C and D are set to be passive Rx, and F is set to be passive Tx.

You may configure both Tx and Rx on one port to operate in the same
mode, or you can configure each Tx and Rx on one port to operate in dif-
ferent modes.
If you set PCI-1603 to the current-loop mode, plug the card to your
device and turn on the device, both LEDs Rx1 and Rx2 on top corner of
PCI-1603 board are lighten, indicating that current-loop mode is enabled!
Enable mode selection
You set the Enable mode using two, four or eight position DIP switches,
one for each port. If the switches are set to "AUTO", the driver automati-
cally senses the direction of the data flow and switches the direction of
transmission. No handshaking is necessary.
If DIP switches are set to "On," the driver is always enabled, and always
in high or low status. The user must select a mode before beginning RS-
422 applications.
Note: When either channel is configured in the RS-232
mode, the two associated Tx/Rx active/passive jump-
ers will be inoperable.
