5.2 Data Format Selection
A group of 10 switches is located on the bottom center of the module’s circuit card (see
Figure 5.2). The left two (2) of these switches control the data format that is
transmitted/received. These switches on both the transmitter and receiver must be set
the same in order to have proper data communications format between them. FT and FR
modules can be configuring different for data format conversion (see Figure 5.1)
The figure and table below illustrates these switch locations on the board and how they
are configured for the proper data format options. The factory-supplied default setting
is for RS-232 data (Switch #1-2 OFF (up)).
