Chapter 3 Installation and Configuration
3.1 Windows utility Installation The ADAM-4577 provides two window-based utilities. One is configuration utility; the other is testing utility. You can configure ADAM4577 in any operating system by using configuration utility via Ethernet . If you want to test the communication situation or download firmware remotely, you can use “testing utility”. The following are the installation instructions for setting up the ADAM-4577. 1.
3.2 Configuring the ADAM-4577 The ADAM-4577 provides easy Windows configuration through Ethernet connection. You can configure various parameters for TCP/IP or UDP configuration easily. For secure administration, it can also restrict the access rights for configuration to only one host PC to enhance network security. With this secure function enabled, other PCs will not have permission for configuration.
3.2.1 Search for Specific ADAM-4577 If you want to locate specific ADAM-4577s, the configuration utility provides a “Locate” function to assist you. You can select all the ADAM-4570/4571/4572/4577/4577/EDG-4504 devices (see Figure 3-2) or just select one ADAM-4577 (see Figure 3-3). When you select a specific device, the LED that stands for “Status” will flash . When you select another device, the original “Status” LED will be red. Please follow these steps: 1. Select “All Devices” and click “Locate” 2.
Figure 3-3 Locate specific ADAM-4577s Configuration utility can only search the ADAM-4570/4571/4572/4577/ 4577/EDG-4504 devices on the local network segment and cannot search beyond a router or gateway. Make sure that all the ADAM4570/4571/4572/4577/4577/EDG-4504 devices that you want to monitor must reside on the same system to identify and locate each Ethernet data gateway device.
Firmware version In this field, the configuration utility represents the firmware version of the ADAM-4577. You might need to refer to the firmware version to determine functions available on the ADAM-4577 device. In case of problems that might concern the firmware version, please provide the firmware version number to our Customer Service. Besides, you can download upgraded ADAM-4577 firmware to meet your requirements.
3.2.2 Network Configuration This section will show network configuration of ADAM-4577’s configuration utility. We will introduce their function and operation by item. Figure 3-4 Network Configuration Window Ethernet: MAC Address This does not need configuration. Link Speed This function will show the current linking speed to be 10Mbps.
TCP/IP: IP address, Subnet Mask, Default Gateway The IP address identifies your ADAM-4577 device on the global network. Each ADAM-4577 has same default IP address 10.0.0.1. Obtain a specific IP address from your network administrator and then configure each ADAM-4577 with the individual IP address. Note: The ADAM-4577 does not support auto IP address configured by DHCP server.
3.2.3 Port Configuration Figure 3-5 Port Configuration Window Name ADAM-4577 provide one port to connected to the serial device. The name default is port1, it goes without your further efforts Description You can give more detailed description of the function of the port for easy management and maintenance. Descriptions longer than 128 characters cannot be used. Type Each ADAM-4577 offers three kinds of serial interfaces: RS-232, RS485 and RS-422.
Flow Control The ADAM-4577 provides one option: None Data Bits The ADAM-4577 provides four options: 5, 6, 7 or 8. Stop Bits The ADAM-4577 provides three options: 1, 1.5 or 2. Baud Rate The ADAM-4577 supports baud rates from 300 to 230,000 bps.
3.2.4 Setting Configuration ADAM-4577 provides TCP/IP and UDP two protocol. In settings, you can choose either TCP mode (see Figure 3-6) or UDP mode(see Figure 3-7) according to your application. In this section, we will show setting configuration in either TCP or UDP mode. As to detailed networking architecture for TCP/UDP application, please refer to Chapter 4.
3.2.4.1 TCP(UDP) Port number The TCP(UDP) port number represents the source port number , and the number is used to identify the channel for remote initiating connections. Range: 1024-65533. If an unknown caller wants to connect to the system and asks for some services, they need to define the TCP(UDP) port to carry a long-term conversation. Each node on a TCP/IP network has an IP address, and each IP address can allow connections on one or more TCP port.
3.2.4.2 Only configure the authorized IP This option is enabled in order to protect all configuration settings from being changed inadvertently. 3.2.4.3 Allow any IP to access If this option is enabled, any PC can access data from this ADAM-4577. 3.2.4.4 The specified IP which can access If this option is disabled, only the specified PC can access data from this ADAM-4577. Due to the difference of TCP and UDP, we will discuss them individually.
3.2.4.5 Port Mode 1. Selected Port The default is Port1, DAM-4577 provide one port to connected to the serial device. 2. Port Mode The default is Data Mode, The ADAM-4577 provide one mode: Data mode. Serial devices that connect to the ADAM-4577 can transmit data to another networking device 3. Data Idle Timeout It only appears in TCP mode, The default is 60 seconds. If you want to keep connection continuously, you can key-in “0”. Data idle Time is the time period in which the device waits for data.
3.2.4.6 Protocol for Communication In this option, you can choose either TCP or UDP mode according to your application. Due to your TCP or UDP mode choice, it will show different setting frame of configuration utility. We’ll illustrate the setting base on TCP or UDP mode. TCP Mode Peer for Receiving Data The option is the setting of another networking device which you want to connect , including IP address and TCP port. It applies to two network architectures: Peer-to-peer and Event-handling.
TCP port of ADAM-4577: &&&& TCP port of ADAM-4577’s port1: &&&& +1 For example: TCP port of ADAM-4577 that you want to connect: 5220 TCP port of Port 1: 5220 +1=5221 If you want to connect to a PC or any system, you have to key-in the TCP port of that PC or system. UDP Mode UDP Timeout Setting (ms) The UDP mode is only applied to Polling network architecture. When you choose UDP mode , Data Idle Timeout option is disable. 1.

2. Inter Frame Break ADAM-4577 provides one smart way to reduce inefficient waiting time.Through Inter Frame Break,ADAM-4577 transmits data more fficiently. Inter Frame Break is a good control machine, ADAM-4577 will distinguish whether it transmits back data to host PC by the function. As to set Inter Frame Break 30 ms, ADAM-4577 won't wait response timeout 1000ms over to transmit data As long as the idle time is longer than 30 ms, ADAM-4577 starts to transmit back data to host PC.
Case2 : Assume the transmitted data spends 600 ms As Setting: Response timeout = 1000 ms Inter Frame Break = 30 ms Time over (Response timeout) 1000 ms Start to transmit Real data time Time over Saving time 600 ms 370 ms 30 ms Host PC Inter Frame Break Figure 3-10 Case2 data time diagram Comparing the difference of the two case, case 2 only wastes 30 ms but saves 370 ms comparing to case1. We see clearly that if we set Inter Frame Break, we could save waiting time.
3.3 Testing Utility The purpose of testing utility is to help you diagnose the communication between devices and download firmware remotely.
3.3.1 Self Test Function The purpose of this test is to confirm the communication from host PC to the ADAM-4577. If there is still an error, you can check the communication from the ADAM-4577 to the serial devices. If the test is selected, an external test will be done to check that the connection signals for each port are working properly. For the test, you will need to connect each port to a loopback tester (provided in the package). The loopback test only applies to RS-232 mode. 1.
