RS-232/422/485 Selection (for PCI-1612A/B/AU/U/CU)
Should you wish to configure the PCI-1612A/B/AU/U/CU to operate in
the RS-232 mode, the bottom two pins of the 12*3 pin jumper should be
connected. For RS-422/ RS-485 mode selection, the upper two pins of the
12*3 pin jumper should be connected as shown below.
