JP7: Disconnect Jumper Header

This header provides jumper positions to connect the XPort AR to the RS-232 Port B
transceiver when this RS-232 serial interface is desired. Any number/combination of these
jumpers may be installed depending on which RS-232 signals are required and which XPort
AR signals are to perform functions other than RS-232 related.

JP8: Disconnect Jumper Header

This header provides jumper positions to connect the XPort AR to the RS-232 Port B
transceiver when this RS-232 serial interface is desired and requires either DSR or DCD.
Since CP12 and CP13 are dedicated to an I
DSR and DCD on port B. This jumper has two positions: 1-2 or 2-3. In the 1-2 position, it
connects the XPort AR signal CP11 to the DSR output for Port B. In the 2-3 position, it
connects the XPort AR signal CP11 to the DCD output for Port B. This choice is made based
on whether the serial interface intends to use DSR or DCD.
