EDS4100 Overview
The EDS4100 is a compact device server that allows you to network-enable
asynchronous RS-232 and RS-422/485 serial devices. It can deliver fully transparent
RS-232/422 point-to-point connections and RS-485 multi-drop connections without
requiring modifications to existing software or hardware in your application.
Ports 1 through 4 support RS-232 devices.
Ports 1 and 3 also support RS-422/485.
Note: RS-485 circuits support 32 full-load devices or 128 quarter-load devices.
Each RS-485 port, however, counts as one device, leaving up to 31 full-load
or 127 quarter-load devices that can be connected to the RS-485 circuit.
The EDS4100 device server supports the Power-over-Ethernet (PoE) standard. With
PoE, power is supplied to the EDS over the Ethernet cable, by either an Ethernet
switch or a midspan device. Being able to draw power through the Ethernet cable
eliminates power supply and cord clutter. It also allows the EDS to be located in
areas where power is not typically available.
