Communication Baud Rate
To configure the communication baud rate, set DIP switches 6 and 7 according to the following table. DIP
switches 6 and 7 control the communication baud rate for port 1 only. Port 6 is fixed at 38400 bps.

Note:
The 115,200 baud rate is supported for use with a Lantronix device. If using a direct connection to
the host workstation, refer to the OnGuard 7.3 Release Notes for supported operating systems.
In order to communicate with an ISC at 115,200 bps, an extra wire is required in the RS-232 cable,
connected to RTS/R1+.
For a 9-pin cable,
•
Jumper pins 4 and 6 together.
•
Connect pin 8 to RTS/R1+ on the LNL-2000.
