Default Settings
The board will be shipped in the RS-232 mode (Enhanced), all the
jumpers on the 12*3 pin jumper will be set to the upper position, this is
the cards default setting. The PCL-746+ DIP switch and jumper default
settings are as shown below:

Protocol Selection
Firstly you have to decide which mode each port will be operating in,
RS-232, RS-422 or RS-485. You can configure each port to operate in a
different mode if required. Each port has to be individually setup by
selecting the correct jumper configurations on two jumper groups, one
pair for each port. These consist of a 12*3 pin jumper (RS-232) and a
1*3 pin jumper (RS-422/RS-485).
Note: The second (RS-422/RS-485) jumper group is ineffective
when the main jumper group is configured to operate in
the RS-232 mode.
RS-232 or RS-422/RS-485 Mode Selection
Should you wish to configure the PCL-746+ to operate in the RS-232
mode, then the upper two pins of the 12*3 pin jumper should be
connected. For RS-422/ RS-485 mode selection, the bottom two pins of
the 12*3 pin jumper should be connected as shown below.
