Alternatively, ports 1 and 3 support RS-422/485 devices.
To connect an EDS4100 serial port to another DTE device, use a null modem
cable.
To connect the EDS4100 serial port to a DCE device, use a straight-through
(modem) cable.
Connect the EDS4100 to one or more serial devices.
1. Power off the serial devices.
2. Attach a serial cable between the EDS4100 and each serial device.
3. Connect an Ethernet cable between the EDS4100 Ethernet port and your

These power-up methods can be used in combination to provide redundant backup
power to the unit.
