5-10 TELNET

The FMS supports a Telnet connection over IP port 23. When properly configured a telnet user can use the
Com1 port of the FMS to communicate to external EIA232 enabled devices. For instance, a user could
properly configure the FMS, open a telnet session and then connect to an LD5100 interface over Com1
EIA232.

5-10.1 Hardware Connections

The Com1 port is located on the back of the FMS. The COM1 Transmit and Receive LEDs are also located
on the back of the FMS.

The EIA232 port allows communications between the FMS and one other device (point–to–point
connection). The EIA232 port has maximum cable length of 50 feet (15.2m).
