Ethernet Data Gateway In this column, you will see all the found ADAM-4570/ADAM4571/ EDG-4504 devices are listed when you use the configuration utility to auto-search ADAM-4570/ADAM-4571/EDG4504 devices. The specific number following each ADAM-4570/ ADAM-4571/EDG-4504 device is its MAC Address. The MAC Address is what helps the local system to identify and locate each Ethernet data gateway device. This MAC Address is already set before delivery from factory, hence no need for further configuration. 36 ADAM-4570/ADAM-4571/EDG-4504 User’s Manual Device Name Configuration utility provides a default name for device to distinguish a specific ADAM-4570/ADAM-4571/EDG-4504 from other ADAM-4570/ADAM-4571/EDG-4504. You can update the default device name based on your application. Names longer than 128 characters cannot be used. It is best to choose a name you can remember. Device Description This field is to record the function, application and other information for each ADAM-4570/ADAM-4571/EDG-4504 device in more detail for easy management and maintenance. You are allowed to describe in your own words. Firmware version In this field, the configuration utility represents the firmware version of the ADAM-4570/ADAM-4571/EDG-4504. You might need to refer to the firmware version to determine functions available on the ADAM-4570/ADAM-4571/EDG-4504 device. In case of problems that might concern the firmware version, please provide the firmware version number to our Customer Service. Type Each ADAM-4570/ADAM-4571/EDG-4504 offers three serial interfaces, RS-232, RS-485 and RS-422. You can use any one of these serial interfaces according to your requirements. Chapter 3: Installation and Configuration 37 3.2.3 Network Configuration Figure 3-6 Network Configuration Window MAC Address This does not need configuration. Link Speed This function will show the current linking speed to be either 10Mbps or 100Mbps. However, the utility will auto-detect the current transmission speed on the network segment and set the transmission speed for the device accordingly without your further efforts. Duplex Mode The utility will detect the current transmission mode (half-duplex or full-duplex) on the network segment, and set the transmission mode for the device accordingly without your further efforts. 38 ADAM-4570/ADAM-4571/EDG-4504 User’s Manual IP address, Subnet Mask, Default Gateway The IP address identifies your ADAM-4570/ADAM-4571/ EDG-4504 device on the global network. Each ADAM-4570/ ADAM-4571/EDG-4504 has same default IP address 10.0.0.1. Obtain a specific IP address from your network administrator and then configure each ADAM-4570/ADAM-4571/EDG-4504 with the individual IP address. Note: The ADAM-4570/ADAM-4571/EDG-4504 does not support auto IP address configured by DHCP server. 3.2.4 Port Configuration Figure 3-7 Port Configuration Window Chapter 3: Installation and Configuration 39 Name To specify which port on the ADAM-4570/ADAM-4571/EDG4504 is to be connected to the serial device. 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-4570/ADAM-4571/EDG-4504 offers three kinds of serial interfaces, RS-232, RS-485 and RS-422. You can use any of the three serial interfaces according to your requirements. Parity The ADAM-4570/ADAM-4571/EDG-4504 provides five options: Even, Odd, None, Space, Mark. Flow Control The ADAM-4570/ADAM-4571/EDG-4504 provides four options: None, Xon/Xoff, RTS/CTS, DTR/DSR. Data Bits The ADAM-4570/ADAM-4571/EDG-4504 provides four options: 5, 6, 7 or 8. Stop Bits The ADAM-4570/ADAM-4571/EDG-4504 provides three options: 1, 1.5 or 2. Baud Rate The ADAM-4570/ADAM-4571/EDG-4504 supports baud rates from 300 to 230,000 bps. 40 ADAM-4570/ADAM-4571/EDG-4504 User’s Manual 3.2.4.1 Host/Device Idle Protection (ADAM-4570 only) When building up a system, users sometimes face the following problems. The system crashes because the serial/Host device breaks down; the application program fails or the cable between the host device and the ADAM-4570 breaks etc. For keeping the stability of system, the users usually have to spend lots of efforts to build up “Redundant” function. Now the ADAM-4570 provides new powerful functions to help users to build up it fast and easily. Focusing on Host PC, serial device, ADAM-4570, the new functions are: Host idle switch, device idle switch and auto-reconnect (refer to Chapter 3.4.4). Host Idle Switch Mode When the application program which is running in host PC fails, the ADAM-4570 and the serial device always “Hang up”. The data can not be sent to other PC. The purpose of the “Host idle switch” mode is to prevent this system hang-up from occurring due to the above problems. If the application program fails, the ADAM-4570 will cut off the connection between the host PC and the ADAM-4570. Another PC can then start to access the same ADAM-4570. Below illustrates t...
