Pelco FR85011A manual Data Communication Switch Setting

With the FT85011A transmitter/FR85011A receiver powered off, set the Data Selection switch to the required data communication using a small screwdriver. Refer to Table A for data communication switch settings.

Table A. Data Communication Switch Settings

Data Communication	Switch Setting
RS-232	0 (default setting)
RS-422	1
RS-485 2-Wire	2
RS-485 4-Wire	3
Manchester/Bi-Phase	4
Coaxitron	5

NOTE: Switch positions 6-9 are not used.

Note the following:

•The FT85011A transmitter/FR85011A receiver allows data translation between RS-232 and RS-422 signal levels. Consequently, the Data Selection switch can be set to 0 (RS-232) on the transmitter and to 1 (RS-422) on the receiver. Conversely, the Data Selection switch can be set to 1 (RS-422) on the transmitter and to 0 (RS-232) on the receiver.

•If you wish to change the data communication setting after the FT85011A transmitter/ FR85011A receiver has been powered on, power off the transmitter/receiver, change the data communication setting, and then power on the transmitter/receiver again.
