RS-232 Ports

There are two PS/2 type serial interfaces - Port A and Port B. The serial ports use a high-density connector. An HP A4301A conversion cable is required to convert to a standard PC-compatible 9-pin male D-sub cable. Figure 4-9shows the RS-232 serial connector. Also refer to Figure 4-1. Table 4-8shows the RS-232-C connector pinouts.

NOTE:The RS-232 Port B is not functional until VME services are operational.
