2.1 Understanding the ADAM-4570/ADAM-4571/EDG-4504
The ADAM-4570/ADAM-4571/EDG-4504 is an advanced data gateway unit. It extends traditional COM ports of a PC with access over a TCP/IP network. Through networking, you can control and monitor remote serial devices either over a LAN or over the WAN.
Since the ADAM-4570/ADAM-4571/EDG-4504 is connected through a TCPIP network, you will need to know some basic facts about networking in order to get the server hooked up correctly.
2.1.1 Network Architecture
Traditional serial port communication uses a COM port board that slides into one of the slots at the back of your PC. In this case, only the computer containing the board can access the serial port. With the ADAM-4570/ADAM-4571/EDG-4504, you are now able to access the COM port from a distance through local area network. The ADAM-4570/ADAM-4571/EDG- 4504 can be integrated within the network architecture of any protocol. Note, all serial devices which are connected to the port must have the same protocol running and the same trans- mission speed. Connect devices running different protocols to different ports of the ADAM-4570/ADAM-4571/EDG-4504.
