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
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.
