3.1.2 DB-9 Pinouts for RS-485 Connection

Four Wire (full duplex multidrop)

Two Wire (1/2 duplex)

Note: The flow signals, RTS and CTS, should be connected as per diagram when unused to prevent loss of
performance on the FieldServer.

For users who do not wish to construct their own connector, we recommend using a DB-9 to screw block
connector which can be purchased from L-Com, Inc.

Ethernet Connection

The FS-X25 Ethernet port automatically senses an uplink connection, and may therefore be connected to a PC or a
hub/switch using either a crossover cable (not supplied) or a direct Ethernet cable (supplied).
