2.5.2 Serial Port, Local (J5)
A DB9 male connector serves as a serial interface with a remote SSPA. Interface
parameters are set by internal RCP hardware and can't be reconfigured by user. The
remote SSPA serial interface must be properly set to provide connection with the RCP
unit. Table 2-2 shows the local serial port pin-out.
2.5.3 Program Port (J6)
A DB25 male connector is used to provide on field flash re-programmability for the
RCP controller card. In order to reload controller board firmware, connect this port to
the PC Parallel port via a straight through cable.
2.5.4 Parallel I/O Connector (J7)
A DB37 Female type connector contains a series of contact closures for monitoring re-
mote SSPA faults as well as opto-isolated inputs for controlling some of the SSPA
functions. Inputs react on the closure to ground. Minimal closure time - 50mS. Table 2-
3 shows details of the parallel I/O pin-out.
