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.
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.
