CHAPTER 2 2 Getting Started In this chapter, you will be given an overview of hardware installation procedure for ADAM-4570W and ADAM-4571W. As mentioned in the previous chapter, ADAM-4570W and ADAM-4571W comes ready for all network connections, including WLAN and RS-232/422/485 port connections..
Chapter 2 Getting Started 2.1 Installation Procedure Overview See the flow chart below for a brief overview of the installation procedure. Figure 2.
2.2 Understanding ADAM-4570W & ADAM-4571W ADAM-4570W and ADAM-4571W are advanced data gateway units. They extend traditional COM ports of a PC by giving them access to an 802.11b WLAN network. Since ADAM-4570W and ADAM-4571W are connected through an 802.11b WLAN network, you will need to know some basic facts about networking in order to get the server hooked up correctly. 2.2.
The following illustration shows a typical network architecture: Figure 2.
2.2.2 LED Definitions There are network status LEDs located on the top panel of ADAM4570W and ADAM-4571W. ADAM-4570W has five, while ADAM4571W has four. Each has its own specific function. Table 2.
2.2.3 Labels To make it easier to remember the relevant IP addresses of your application, we have provided five labels. Use these to note information like where the host PC is mapped to the ADAM-4570W or ADAM-4571W port, and place it in a secure location. Examples: 172.18.1.59: The IP address of specific ADAM-4570W. 160.59.20.89: The IP address of specific host PC mapped to this port. Figure 2.3: Sticker 2.2.
In the same way, there are two kinds of BSS -- infrastructure mode and ad hoc mode -- exist in Diagnostic Mode. Table 2.2 shows how to enter the mode you want by adjusting the switch. Table 2.
2.3 Connecting the Hardware Next, we will explain how to mount your ADAM-4570W /ADAM4571W module, and then how to connect to the WLAN network, hook up the power cable, and connect the ADAM-4570W/4571W’s serial port to serial devices. Note: If you are planning to install other communication cards, we recommend that this is done before the ADAM module is installed. 2.3.
DIN Rail Mounting You can mount ADAM modules on a standard DIN Rail. First, using two screws, attach the DIN rail bracket to the ADAM module. Because the screw heads are flat, the top of the screws will be even with the module’s front panel surface. You can now snap the ADAM module to a DIN rail. Figure 2.
Piggyback Stack ADAM modules can be stacked as shown in the figure below. Figure 2.6: Piggyback Stack 2.3.2 Wireless Connection ADAM-4570W and ADAM-4571W operate in the 802.11b WLAN environment, which is created by an access point working with 802.11b protocols. Locate your access point and connect to the Ethernet network first. Then build up the connection between the access point and the ADAM-4570W/4571W (Refer to Appendix A "Quick Start").
Power Connection You should take the following steps to connect power to the ADAM module. 1. Connect the power cable to the 2-pin connector. 2. Connect the power cable to the power adapter. Figure 2.7: Power Connection for ADAM-4570W/4571W If ADAM-4570W / ADAM-4571W are working properly, the green power LED will be lit.
2.3.3 Serial Connection ADAM-4570W has two, while ADAM-4571W has one RJ-48 serial port phone jack on the bottom. You may use the supplied RJ-48 to DB9 cable to connect your serial device. Simply plug the RJ-48 end of the cable into the jack, and plug the DB9 end into the serial connector of the serial device. The pin assignment of the RJ-48 to DB-9 cable is shown in the table below. Table 2.
CHAPTER 3 2 Installation & Configuration This chapter first guides you in the installation of drivers and software utilities, and then shows how to use the software utilities.
Chapter 3 Installation & Configuration 3.1 Driver and Utility Installation In order to use a PC via an Ethernet network to control serial devices connected to ADAM-4570W or ADAM-4571W, you must first have a host running Windows 98/NT/2000 or XP. You also need the host to have an Ethernet card and TCP/IP protocol installed. Following are the installation instructions to set up ADAM-4570W / ADAM-4571W. 1. Insert the Advantech INET SERIES DRIVER UTILITY CD-ROM into the CD-ROM drive (e.g. D:\) on the host PC.
3.2 Configuring EDG Series-ADAM-4570W/4571W ADAM-4570W and ADAM-4571W are part of Advantech’s EDG Series. All products in the EDG series provide easy Windows configuration through an Ethernet or WLAN connection and the ‘Configuration Utility’ program. ‘Configuration Utility’ can automatically find all compatible devices on a network for easier configuration of parameters for TCP/IP.
Figure 3.1: Locate All EDG Series Or select a group of ADAM-4570 with these steps. 1. Select “Designated” and then “ADAM-4570”, and last “Locate”. 2. The “Status” LED of all “ADAM-4570” on the LAN will be lit. Figure 3.
Of course, you can select just one ADAM-4570W if you like. When you select a specific device, the LED that stands for “Status” will be lit for 8 minutes. If you select another device, the “Status” LED of the first selected device will turn off. Figure 3.
3.2.2 System Configuration ‘Configuration Utility’ can only search for EDG devices on the local network and not beyond a router or gateway. Make sure that all EDG devices that you want to monitor reside on the same local network as the host PC. Figure 3.4: System Configuration Window Device Name ‘Configuration Utility’ provides default names for the devices it finds on the network. This is to distinguish the EDG devices from each other.
Firmware Version In this field, ‘Configuration Utility’ shows the firmware version of the EDG device. You might need to refer to the firmware version to determine what functions are available on the EDG device. In case there are problems concerning the firmware version, please provide the version number to our customer service. 3.2.3 Network Configuration Figure 3.5: Network Configuration Window-General Wireless Firmware Here is the firmware version of the wireless module embedded in the ADAM-4570W/4571W.
Region Set the region. Each region has its default channel range. When you choose a specific region, the optional channel range and numbers in the below drop-down menu will be changed automatically. • General (USA and Canada): 1~11 • Europe (except for France and Spain): 1~13 • France: 10~13 • Spain: 10~11 • Japan: 14 only • Japan Wide: 1~14 For other regions, please choose General, or refer to table 3.1 to find an acceptable frequency.
Channel Each region has its default channel range, which is decided by each region’s telecommunications laws. Table 3-1 shows the corresponding frequency of channels. If you wish to setup two networks, it is recommended that you use channels that are not close to each other to minimize interference. Table 3.1: Channel and Frequency Corresponding Table Channel Frequency(GHz) 1 2.412 2 2.417 3 2.422 4 2.427 5 2.432 6 2.437 7 2.442 8 2.447 9 2.452 10 2.457 11 2.462 12 2.467 13 2.
SSID The SSID (Service Set Identity) identifies a specific wireless LAN. Before associating with a particular wireless LAN, a station must have the same SSID as its access point. That means the user must set the specific access point’s SSID in infrastructure networks, or set the same SSID in ad hoc networks. If the user doesn’t know which access point is the most appropriate one, just set “ANY” for an automatic search. The frame on the right appears with the current associated AP’s MAC address and SSID.
The “Advanced” drop-down menu identifies several parameters that are related to the 802.11b wireless network. We suggested the default settings are not changed unless necessary. Table 3.2: Advanced Parameters’ Default Value and Range Parameters Default Value Range Beacon Interval 100 0~65535 RTS Threshold 2347 0~2347 Fragment Threshold 2346 256~2346 Preamble Long Long/Short Beacon Interval In infrastructure networks, the access point periodically sends beacons.
RTS Threshold RTS Threshold is the frame size above that an RTS/CTS handshake will be performed before attempting to transmit. RTS/CTS asks for permission to transmit to reduce collisions, but adds considerable overhead. Disabling RTS/CTS can reduce overhead and latency in WLANs where all stations are close together, but can increase collisions and degrade performance in WLANs where stations are far apart and unable to sense each other to avoid collisions.
Figure 3.7: Network Configuration Window-“Authentication” WEP Authentication Type WEP (Wired Equivalent Privacy) is a kind of standard to encrypt the data frame. • Open system: No encryption for network communication. You can neglect the key setting on the right side. • WEP Share Key: Both communication devices use the same key as encryption. • Automatic: Detect the WEP situation of the access point automatically. ADAM-4570W/4571W will use the current key for encryption.
Key Index This lists the supported encryption keys that you can choose from. Key Format Set the key format. Table 3.3 shows the allowed characters and length of the different key index and key formats. Table 3.3: Key Setting Index Alphanumeric Hexadecimal 64 bits Up to 5 random characters on the keyboard Up to 10 random hexadecimal characters (0 ~ 9, a ~ f) 128 bits Up to 13 random characters on the keyboard Up to 26 random hexadecimal characters (0 ~ 9, a ~ f) Figure 3.
3.2.4 Port Configuration Figure 3.9: Port Configuration Window Name Select which port on the EDG device is to be connected to the serial device.
