SETTING THE DATA COMMUNICATION MODE
A Data Select switch, which is a 10-position rotary switch, is provided on the bottom of the FT106011
transmitter and the FR106011 receiver (refer to Figure 5). The Data Select switch allows you to set
the data communication mode required for the transfer of data.
With the FT106011 transmitter/FR106011 receiver powered off, set the Data Select switch to the
required data communication mode using the supplied screwdriver. Table B lists Data Mode Select
switch settings and associated data communication modes as indicated on the bottom of the units.
Note the following:
• The FT106011 transmitter and the FR106011 receiver allow data translation between RS-232
and RS-422 signal levels. Consequently, the Data Select switch can be set to 0 (RS-232) on the
transmitter and to 1 (RS-422) on the receiver. Conversely, the Data Select 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 mode setting after the FT106011 transmitter/
FR106011 receiver has been powered on, power off the transmitter/receiver, change the data
communication mode setting, and then power on the transmitter/receiver again.
