9.5.1.2 VME P2 Connector
Table 9-4 : VME P2 Connector
The serial port signals (SER_x) are shown in the TVME8240 pin function. E.g. for serial port A
the external TXD line must be connected to pin C28 (SER_RXDA), NOT to pin C27 (SER_TXDA).
For serial port B: The pins are used as the RS422+ signal lines when the RS422
adapter is used. The SER_xB(-) pins are used as the RS232 signal lines when the RS232
adapter is used and are used as the RS422- signal lines when the RS422 adapter is used.
For each serial port only one connection scheme is allowed at a time, either via the VME P2
connector or via the front plate DB9 connector.
Please see the SCSI Interface section for using 16bit SCSI Targets on the VME P2 connector.
