2.1 Understanding the EKI-1528/1526

The EKI-1528/1526 is network-based, serial device server for connecting RS-232/

422/485 serial devices, such as PLCs, CNCs, scales, and scanners, directly to a

TCP/IP network. Once connected through the EKI-1528/1526, the serial devices will

be able to send and receive data on a network like any other network devices. 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 EKI-1528/1526 is connected through a TCP/IP network, you

might need to know some basic facts about networking in order to get the server

hooked up correctly.

After the simple installation steps to attach your network and serial device to the

appropriate connectors on the serial device servers and driver installation, you will

then be able to communicate with the serial devices via its own application software

and with the EKI-1500 serial device servers. COM port redirector, TCP server mode,

TCP client mode, UDP server mode, UDP client mode and Control mode are all

different schemes to make a serial connection across using one or more Serial

device server.

The EKI-1528/1526 provides dual Ethernet ports that can establish two physical

Ethernet connections. Dual connections enable an alternative backup session that

host can connect to device server by the way of second connection while the primary

connection should be lost or dropped.
