Zones To maximize the number of frequencies available for larger venues such as corporate campuses, festival venues, and theaters, you may be able to divide the environment into zones. Creating zones in Wireless Workbench tells the frequency compatibility calculator to assume that systems in one zone will not create intermodulation distortion with systems in another zone.
System Setup and Configuration Part 2 Chapter 8 ‒ Wireless Workbench Configuration Example.................................................................................34 Chapter 9 ‒ RF Connectivity and Antennas.........................................................................................................50 Chapter 10 ‒ Networking.......................................................................................................................................
Chapter 8 ‒ Wireless Workbench Configuration Example This chapter covers the steps of pre-show planning using tools in Wireless Workbench. Step 1: Setting up a show file Set up the show properties by clicking File > New Show. Enter the details of the show, venue, and contact information that can be saved as a show file (.shw) in Wireless Workbench.
Step 2: Adding devices to inventory and setting up zones Click Add new device on the toolbar to choose devices for the show. From the list of manufacturers, models, and bands, select the device type and pre-configure the frequency to allow the system to find the best available, or manually enter the frequency. If using zones, it's convenient to set up zones for the show while in the inventory chooser. Tip: All device and channel settings can be set from the inventory view.
Step 3: Naming devices Once the devices are entered into the inventory, assign individual names to the device ID and channel name. For the example below, the device IDs are RX1, RX2, RX3, and the channel names are Vocal1, Vocal2, Vocal3, Vocal4, Guitar1, Guitar2.
Step 4: Entering television station information Enter the television station information that Wireless Workbench will take into account when performing the frequency coordination. Select the Frequency Coordination tab, and then Change TV Channels… under the ‘Coordination’ tab. Specify the location of the venue by entering the city and postal code, or entering the latitude and longitude by selecting geo data in the location setup box.
Step 5: Selecting channels to coordinate Use this step to select the channels that will receive new frequencies from the calculation. Unselected channels will retain their frequency and not be altered by the frequency coordination and calculation process in Wireless Workbench. During the frequency calculation for selected channels, unselected channels will be analyzed as part of the overall solution.
Step 6: Entering frequency scan data If scan data for a venue is available, import the scan file (.sca) into Wireless Workbench. Saved scan data can also be imported from the AXT600 Spectrum Manager if it is connected to Wireless Workbench. If scan data is not available during the pre-show planning, live scan data from the venue can be included later.
Step 7: Entering Exclusion ranges Enter additional individual frequencies or frequency ranges to exclude from the frequency coordination process. If you have the Automatically calculate exclusions from scan data preference checked in the Coordination tab of preferences, exclusions will be generated by the scan data in the Coordination plot and the exclusion threshold level.
Step 8: Save Show File At this point, the pre-show planning for this venue is complete. Save the inventory, scan data, television station, and exclusion information into one file and recall it at the venue. Select the File > Save menu option to save the show.
Step 9: Matching inventory to live devices (including merging devices) At the venue with the live devices set up and configured, load the show file and configure the devices. Open the show file from the File > Open Show menu. If the devices in the show file have never been matched to the actual live devices, WWB adds the offline devices to the inventory. Drag each offline device onto its corresponding live device to merge them into a single device in the inventory.
Step 10: Frequency coordination and deploying frequencies to live devices If a prior frequency scan data from Step 6 is not available, select the Frequency Coordination tab at the top of the application, then select Change Scan Data.... From the Scan Data window select Settings.
Choose which device to use for the scan (either a receiver or a Spectrum Manager) and enter the frequency range to scan. Click Start to perform the scan. Once the scan is completed, select Calculate New Frequencies from the Coordination panel. WWB will calculate a new compatible frequency list (CFL) using the device list, TV channel information, exclusion threshold, and scan data. WWB will then display a new window with the frequency calculation results.
Step 11: Setting up and using monitor views To monitor live devices in real time, select the Monitor tab. From the Device Chooser, select the channels to monitor. Drag the individual channel strips around to place them in any order. Select which parameters to show and how many channels per row to display by right-clicking Channel Strip Settings anywhere in the monitor area. Set up channel groups by selecting the Channel Group heading, clicking Add Group, and then naming the channel group.
Step 12: Viewing the frequency list from the Spectrum Manager Selecting Frequency List from the tool bar displays real-time analysis of frequency list monitored by the Spectrum Manager. The Spectrum Manager continuously measures and ranks the frequencies based on noise and interference.
Step 13: Using the ShowLink, Frequency, and RF History Plots Wireless Workbench provides plots to show activity in the ShowLink 2.4 GHz spectrum, RF Spectrum. Additionally, an RF History plot is available to record transmitter signal strength over time. ShowLink Plot A dedicated 2.4GHz scanning radio inside the ShowLink Access Point (that is separate from the ShowLink radio) continuously scans the 2.4GHz spectrum to generate the ShowLink plot. The ShowLink plot contains a live 2.
Frequency Plot Use a receiver or Spectrum Manager to perform real-time, wideband frequency scans that can be overlaid and saved to a file. Select the Scanner Setup… button in the Frequency Plot window to choose which device to use to perform the scan and set the start and stop frequencies. If using a Spectrum Manager, choose the resolution bandwidth (RBW) and step size of the scan.
RF History Plot The RF History Plot measures and records the signal strength of a transmitter as measured by a receiver over time. The RF History Plot is also referred to as a ‘walk-around’ plot since WWB can be set to record the transmitter signal as you walk the venue to ensure proper antenna placement and coverage. Select the Add Channel… button in the RF History Plot window to select which receiver channel to record. Up to 20 receivers and channels can be selected to record at one time.
Chapter 9 ‒ RF Connectivity and Antennas The following sections cover routing the RF antenna signal to receivers, Spectrum Managers, and antenna distribution systems. Antenna Placement Proper antenna placement has an enormous impact on RF system performance. In general, receiver antennas should be at least six feet above ground level and at least six feet away from other antennas. Maintain a clear line-of-sight between transmitters and receiver antennas.
RF Cascade Ports The RF cascade ports provide a connection point allowing additional receivers, Spectrum Managers, or Antenna Distribution Systems to share the RF signal. The following components have RF cascade ports: • AXT600 Spectrum Manager • AXT400 Receiver • AXT630 Antenna Distribution System The following table lists the characteristics of the cascade ports for each component.
AXT630/AXT631 RF Output Distribution The RF distribution ports of an AXT630 or AXT631 Antenna Distribution System send the signal from a pair of antennas to up to 4 receivers or additional antenna distribution systems. Port-to-port isolation reduces interference, making the distribution ports the best option for distributing signal to additional devices. AXT630/AXT631 Signal Flow AXT 630/ AXT631 Circuit Diagram Antenna In 50 Ω Cascade Out Distro Out 1 50 Ω 0 dB Distro Out 2 50 Ω -5.
Multiple Levels of Antenna Distribution For large configurations, multiple AXT630s or AXT631s can be layered to support up to 3 levels of signal distribution: Note: For best RF performance, use all the RF outputs on one level before creating additional levels.
Chapter 10 ‒ Networking Connecting components using an Ethernet network enables advanced Axient features such as automatic frequency assignment, remote control and monitoring, and interference avoidance. Adding a computer to the network allows you to run Wireless Workbench® 6 (WWB6) to control and monitor devices on the network.
Configuring Network Settings with the AXT620 Ethernet Switch The switch is managed from an embedded web server, which offers advanced configuration features and lets you access the switch from anywhere on the network through a standard web browser. The Web-Based Management supports Internet Explorer 6.0 or later versions. Default Values System Login IP Address: 192.168.1.1 1. Open a web browser. In the address bar, enter the IP address of the switch, and then press Enter.
Network Topologies There are several ways to configure a network of devices. In general, you should always use a "star" network topology where each device uses one connection to an Ethernet switch port. If multiple switches are used, each switch is individually connected to one connection to the next level of Ethernet switch. Below are three example configurations of large networks of devices.
Multiple Ethernet Switch Setup #2 Each networked device needs an individual connection to the switch.
Multiple Ethernet Switch (Wi-Fi) Setup #3 Each networked device needs an individual connection to the switch. Showlink Acces Point Axient Wireless Wi-Fi Router (DHCP enabled) AXT610 802.
Assigning IP addresses to Networked Devices Each device on the network must be assigned a unique IP address to ensure network communication. IP addresses can be assigned automatically by a DHCP enabled server such as the Shure AXT620 Ethernet switch, or manually assigned from a list of valid IP addresses. Note: Selecting the reset option for a device will clear existing IP addresses and set the IP address mode to Automatic. Automatic IP addressing 1.
Connecting a Computer to the Network Connecting a computer to the network allows you to run Wireless Workbench® 6 to control and monitor devices on the network. A computer can be connected to any Ethernet port in the system. The Shure AXT620 Ethernet switch offers a convenient front panel port for easy computer connection. Connecting to devices via USB is not supported in Wireless Workbench 6. An Ethernet connection is required for WWB6 control.
Configuring Wi-Fi for Wireless Networking When using Wireless Workbench over Wi-Fi, it’s important to set up the wireless router properly for best performance. Wireless Workbench employs ‘multicast’ data protocols to communicate to the Axient and PSM1000 devices. Wi-Fi treats broadcast and multicast packets differently than general packets for backward compatibility reasons.
Chapter 11 ‒ Axient Rechargeable Battery System Axient lithium-ion rechargeable batteries use advanced chemistry that maximizes transmitter runtime with zero-memory effect. Axient power management provides detailed visibility to critical battery parameters such as health, charge status, temperature and cycle count.

Backup Options using Standard AA Batteries In the event that a Shure rechargeable battery is not available, optional battery sleds and carriers are available to allow the transmitter to use standard AA batteries as an emergency backup. Runtime using standard batteries will be less than a Shure rechargeable battery. The AXT913 3-AA battery sled holds 3 AA batteries and can be used to power the AXT100 bodypack transmitter.
Chapter 12 ‒ ShowLink™ Network ShowLink remote control enables real-time remote adjustments of all transmitter parameters using a wireless network connection between linked Axient transmitters and receivers. Whether performers are on stage in the middle of a performance, or off stage waiting for their cue, ShowLink lets you make crucial changes to transmitter settings without interrupting the performers.
Coverage Area The coverage area of the access point is approximately the same as the transmitter’s UHF range (depending on the RF squelch setting of the receiver). Use the ShowLink Test feature in the receiver menu to map the boundaries of the coverage area. Multiple access points can be used to increase the coverage area or to expand coverage to multiple rooms. Transmitter Capacity A single access point supports up to 16 Axient transmitters.
Positioning the Access Point Use the following guidelines when positioning the access point: • Provide a clear line of site between the access point and transmitters • Mount the access point on a microphone stand or wall to elevate above crowd level • Position the antenna vertically for optimal performance.

Chapter 14 ‒ RF Range and Selectivity Antenna Type and Placement Using the proper antenna type and placement can dramatically impact the usable range of any wireless microphone system. For an overview of general antenna selection and placement, see the “Antenna Setup” (http://www.shure.com/idc/ groups/public/documents/webcontent/us_pro_antenna_setup_ea.pdf) educational publication on www.shure.com. The following antennas are compatible with the Axient Wireless System.
Antenna Distribution Gain Adjustment The AXT630/631 has a user‐adjustable RF gain setting that ranges between ‐15 dB to +3 dB and is active on all antenna output ports and both channels equally. After selecting the antenna type, placement, and RF cable used to route the antennas to the Antenna Distribution System, it’s important to optimize the RF signal level going into the receivers for best signal‐to‐noise ratio.
Channel Spacing The AXT400 Receiver has been specifically designed to provide superior RF channel spacing down to 250kHz while rejecting adjacent high‐power RF signals. In the receiver filter response plot below, the shape factor and selectivity of the receiver provides the ability to place more wireless microphones on the air in less spectrum.
Chapter 15 ‒ Interference Detection and Avoidance In crowded RF environments, interference can come from anywhere. Other wireless microphones, intercoms, and a growing number of digital devices all have the potential to interfere with wireless audio channels. Interference from these devices can strike without notice, compromising the audio signal and creating dropouts.
On-Screen Frequency Change Options When Avoidance mode is set to Prompt, the following on-screen options are available when interference is detected: • Switch: Deploys a clear backup frequency from the Spectrum Manager when selected • Manual: Accesses the frequency menu to make a frequency change using the control wheel • Ignore: Suppresses the interference warning message Detection Sensitivity The sensitivity setting allow you to vary the timing of warning messages to match the RF conditions and the need
Interference Avoidance The options available for moving to a clear frequency depend on the components in the system.
Chapter 16 ‒ Frequency Diversity Frequency Diversity enables seamless, uninterrupted audio for mission-critical applications. Frequency Diversity works by transmitting the audio on two independent frequencies from an AXT200 Frequency Diversity handheld transmitter or from two AXT100 bodypack transmitters. When operated in Frequency Diversity mode, the AXT400 receiver uses the best combination of the two frequencies to provide a single channel of audio.
Setting Frequency Diversity Mode The AXT400 receiver has selectable Handheld and Bodypack modes to optimize Frequency Diversity performance when using each transmitter type. Note: Set Diversity mode to Off to use the receiver for two separate audio channels. FD-Handheld Mode Configures the receiver for Frequency Diversity operation with an AXT200 handheld transmitter. FD-Bodypack Mode Configures the receiver for Frequency Diversity operation with two AXT100 bodypack transmitters.
Linking a Diversity Handheld Transmitter Link the transmitter and the receiver to set up a Frequency Diversity audio channel. 1. Set the receiver to FD-Handheld mode: Radio > Options > Diversity sync RF navigate audio RF navigate audio control monitor power clip AXT400 A 470-698 MHz A B A B OL push enter OL 1 2 exit Dual Wireless Receiver push 2. From the receiver menu select: Tx 3. Align the transmitter with the IR port on the front panel.
Bodypack Frequency Diversity Calibration For optimal performance, the audio levels between 2 AXT100 bodypack transmitters must be set within 1 dB when used for Frequency Diversity. The AXT400 receiver has a bodypack calibration mode that graphically compares the audio levels between the bodypacks, allowing for precise calibration. If the bodypacks are enabled with ShowLink remote control, real-time adjustments can be made from the calibration screen. Otherwise, make adjustments using the bodypack controls.
Chapter 17 ‒ Frequency Coordination and Spectrum Management RF coordination and spectrum management finds the best parts of the spectrum for setting up a wireless audio system. The AXT600 Spectrum Manager offers on-board scanning of the UHF spectrum to find all clear and compatible frequencies for wireless audio channels. The Spectrum Manager analyzes and compiles all frequencies into a compatible frequency list (CFL) for deployment over the network to components.
AXT600 Spectrum Manager Design The AXT600 Spectrum Manager is a unique, 8-band, parallel-processed receiver with three selectable detector bandwidths and an FM-demodulated audio headphone output for quick monitoring.
RF Scanning: Design and Resolution The design of the Spectrum Manager supports wideband frequency scanning over the UHF band. Eight parallel receivers and three selectable detector bandwidth options (1MHz, 200kHz, 25kHz) available in Wireless Workbench enable very fast frequency scanning in just a few seconds. If used without Wireless Workbench, the Spectrum Manager selects the 200kHz bandwidth (RBW) filter to closely emulate the receiver filter response.
Before Starting an RF Coordination Use the following guidelines to ensure accurate RF coordination and maximize the number of frequencies available.
RF Coordination Wizard The Spectrum Manager includes a wizard to provide guided device and frequency configuration. Choose one of the following set up task options: All New Update Freqs For initial RF coordination. • Finds receivers and other devices on the network to manage • Scans the RF spectrum for available frequencies • Calculates a compatible frequency list (CFL) to match the needs of the networked devices Refreshes the frequencies for an existing wireless system.
Update Freqs Wizard Option The following example shows the steps for updating frequencies for networked components by using the Update Freqs option. Choose Setup Task All New Update Freqs Update Devices 1. From the home menu screen choose Wizard and select the Update Freqs option. 3. Allow the scan to complete. Press Next. Scanning Exit Antenna A 27 compatible frequencies Power off or RF Mute all transmitters that will receive frequencies from this coordination Next 2. Mute all transmitters.
Exclusions Most RF environments contain frequencies where it is not desirable to operate wireless equipment, such as those reserved for local broadcasts, public safety, or other users. Exclusions prevent the Spectrum Manager from including these frequencies when calculating a compatible frequency list. Entering Exclusions Exclusions Format Add Clear Clear All 1. From the Spectrum Manager menu: CFL > New > Exclusions 2. Select the Add option. 3.
Editing a Compatible Frequency List Use the Edit menu option to edit the CFL. From the Spectrum Manager menu: CFL > Edit 1 3 2 4/55 478.750 MHz Type: AXT Sts: Ready (-102 dBm) 4 Add Del Listen Edit 6 5 ① Frequency/Total Displays the currently selected frequency and the total number of frequencies in the CFL. Use the control wheel to scroll and select a frequency.
Spectrum Monitoring The Spectrum Manager provides tools for examining, tracking, and troubleshooting the RF spectrum. Backup Frequency Monitoring During operation, the data screen tracks the status of frequencies available for Axient channels in the system. The total number of frequencies available for each band are displayed, including real-time status of in-use and backup frequencies. Backup frequencies which have been degraded by the monitoring function are removed from the count of Ready frequencies.
Event Log The event log records the actions of the Spectrum Manager and other devices it manages, as listed below. The log stores up to 150 events. The start of an event record is indicated with an asterisk (*). The most recent events appear at the top of the log. Use the control wheel to scroll through the list of events. When the storage limit is reached, the oldest events are overwritten. Note: A power cycle or firmware update will clear the event log.
Troubleshooting Part 4 Chapter 18 ‒ RF and Audio Troubleshooting....................................................................................................108 Chapter 19 ‒ Network and ShowLink Troubleshooting....................................................................................117 Chapter 20 ‒ Wireless Workbench 6 Connectivity Troubleshooting..............................................................
Chapter 18 ‒ RF and Audio Troubleshooting The Axient Troubleshooting Method The job of a communications system is to transfer a signal, or message, from one location to another. Most communication systems contain a sender and a receiver, and may have multiple paths, or hops, between the sender and receiver. When the signal, or message, doesn’t make it all the way from the sender to the receiver, that typically means some part of the communications link is either malfunctioning or not set up correctly.
Basic Diagnostic Checklist Use this checklist as a first step when troubleshooting the Axient system. If the system fails a test, refer to the related troubleshooting section appearing in brackets at the end of the step.
RF and Audio Troubleshooting Let’s start with an example of an Axient system identifying the RF links and audio links: RF Link Audio Link 4 5 3 1 6 2 Transmitter (sender) Antenna Distribution Amplifier 7 10 6 Receiver 1 Spectrum Manager 6 11 8 6 Receiver 2 9 12 ① Microphone ⑦ Antenna distribution amplifier ② Transmitter (sender) ⑧ Receiver 1 ③ Transmitter antenna ⑨ Receiver 2 (receiver) ④ Electromagnetic waves (RF and Audio) ⑩ Spectrum Manager ⑤ Receiving antenna ⑪ Audio output cab
Step 1 (Receiver 2) The usual indicator of an RF problem is the RF LEDs on the receiver are not on. If the RF LEDs on the receiver are all on, that usually means the RF link is working. Check that the receiver 2 is plugged in, and the power switch(s) are ON The Axient products have two power switches, an AC mains switch on the rear of the unit and a standby switch on the front.
Step 3 (Receiver 1) Check that the receiver 1 is plugged in, and that both power switches are ON The RF cascade ports will not pass the RF signal if the receiver 1 is off. Check the frequency band of receiver 1 It should match the frequency band of receiver 2 since you’re using the RF cascade port to feed the receiver 2. Note: The linking, channel name, or ShowLink settings of receiver 1 have no effect on the RF cascade output.
Step 6 (RF Cables) Check the RF cable connections to the antenna distribution amplifier The cables should be securely plugged into the top BNC input jacks; they should NOT be plugged into either of the bottom BNC cascade jacks or into the Channel A/B RF outputs. Check the RF cable connectors Unplug the cables from both ends and inspect the connector and center pins to ensure they are not missing or damaged.
Step 10 (Transmitter) Check the transmitter power and battery Ensure the transmitter is powered on and the battery is charged and properly seated in the transmitter. Check the RF MUTE setting If the transmitter is RF MUTED, the LCD display will alternately flash ‘RF Muted’ and the set frequency. Check the frequency of the transmitter against the receiver The transmitter and receiver frequencies as well as the frequency band must exactly match.
Step 13 Receiver Audio Settings In addition to checking all the other areas outlined in Step 1 of the RF troubleshooting chapter, you should also check the following audio areas. Check the MIC/LINE switch setting on the rear panel of the receiver The MIC/LINE switch changes the audio output level of the XLR output by 30 dB. If you have a low audio signal and the switch is set to MIC, try switching it to LINE.
RF Troubleshooting Table Use the following table as quick reference to troubleshoot common RF problems Symptom RF LEDs not lit on receiver Possible Cause Solution Transmitter set to RF Mute Unmute RF output Incorrect Squelch setting Adjust Squelch, lower squelch for extra range AC power switch OFF for rack device suppling RF signal Objects in path between transmitter and receiver Band Mismatch between transmitter and receiver Frequency mismatch between transmitter and receiver RF cable or Connec
Chapter 19 ‒ Network and ShowLink Troubleshooting We’ll start with an example network topology that does not have a computer connected but does have a DCHP address server on the network. We’ll cover the topologies with a computer connected in the chapter on Wireless Workbench troubleshooting.
Step 1 (Receivers) For this example, we’ll start at the receivers for our troubleshooting method. Check that the receivers are plugged in, and that both power switches are ON The Axient products have two power switches, an AC mains switch on the rear of the unit and a standby switch on the front. Check the FIND ALL status at the receiver The FIND ALL function from the Util > Network > Find All menu will query any other Axient devices on the network and ask for their model number and address properties.
Step 4 (Ethernet Switch 2 Cables) Check the network cable If the LEDs are not on at the network jack, check the cable connector for damage to the pins or broken or frayed connections on the cable. Ensure the cable is securely plugged into both the Ethernet switch 2 and Ethernet switch 1. Try a replacement cable if you suspect a problem with the cable. If all of the above steps are completed with no problems found, proceed to Step 5.
Note: It’s possible to have the channel names of the transmitter and receiver match, but not have the two devices linked. If you link a transmitter and receiver via the IR sync, they will be linked. If you then turn the transmitter off and link a second transmitter to the receiver over the original link in slot 1, the receiver will unlink the first transmitter from the ShowLink network, but the channel name of the first transmitter will not change once it’s powered back on.
Network Troubleshooting Table Use the following table as a quick reference to troubleshoot common network problems.
Discovering the IP Address of an AXT620 Ethernet Switch If you cannot connect to the switch at the default IP address (192.168.1.1), it’s likely the switch is set to another IP address. You can always use the reset button to restore the default IP address; however, your user-defined settings will be lost. As an alternative, it’s recommended to use a downloadable Ethernet packet analyzer program such as Wireshark® (www.wireshark.org) to identify the IP address of the switch.
➋ Allow Wireshark to run for at least one minute, and then stop the packet capture 2 Chapter 19 ‒ Network and ShowLink Troubleshooting 123
➌ In the filter box, type “lldp” ➍ Click Apply ➎ Select one of the LLDP packets 4 3 124 Part 4: Troubleshooting 5
➏ Expand the “Link Layer Discovery Protocol” line ➐ Expand the “Management Address” line ➑ The IP address of the AXT620 is displayed in the “Management Address” line 6 7 8 Chapter 19 ‒ Network and ShowLink Troubleshooting 125
Chapter 20 ‒ Wireless Workbench 6 Connectivity Troubleshooting This chapter on Wireless Workbench connectivity troubleshooting builds on the networking and ShowLink troubleshooting sections. We’ll use the example in the network section and add a computer to the setup. The most typical symptom of Wireless Workbench connectivity problems is that the devices don’t show up in the Inventory Manager, or they were once in the Inventory Manager but are now offline (and grayed-out).
Step 1. (Wireless Workbench) Check Wireless Workbench network configuration The first step in troubleshooting Wireless Workbench connectivity is to check which network connection it’s using. There are often several network connections on a computer such as a wired Ethernet, wireless Ethernet (Wi-Fi), VPN, wireless 3G/4G, and USB-to-Ethernet. Wireless Workbench is designed to only use one network interface at a time.
Step 2. (Computer) Check the computer-to-network IP connectivity. If Wireless Workbench is configured to use the proper network interface, then the next step is to check the connectivity from the computer to the network. The simple way to check connectivity from the computer to the network is to use the ‘PING’ command on the computer. Find an IP address on one of the devices on the Axient network such as an AXT400 Receiver (192.168.1.10 for example).
Step 3. (DHCP server) If the computer is configured to automatically get an IP address from the DHCP server, you can verify this by checking the DHCP client table on the AXT620 Ethernet switch. Check the DHCP server configuration. Log into the AXT620 Ethernet switch by opening a web browser and navigating to the DHCP server address by typing its IP address (default = 192.168.1.1) into the URL window.
Check the DHCP client table. Select ‘DHCP server’ from the main menu and then ‘Client Entries’ from the middle menu. The DHCP client table should include the computer IP address as well as the IP addresses of all the devices on the network. If you do not see the IP address of your computer in the client table, check the DHCP server switch on the front panel to ensure it is set to ON.
