Parallel Port Configuration And Connection - Xycom XVME-976/202 Manual

mode. It is the responsibility of the user's software to provide a protocol that
can handle the bi-directional nature of the interface. The four handshake in-
put signals (RI, CTS, DSR, and DCD) are tied active by the jumpers in-
stalled at W11, W12, W13, and W14 when this port is configured for RS-
485 (refer to Tables 2-10 and 2-11).

Parallel Port Configuration and Connection

Table 2-16 lists the connector pin assignments for the parallel port at J3. In
addition to the pins of connector J3, Table 2-16 also lists the corresponding
pins for the DB25F parallel connector cable supplied with the unit. The
pinout of J3 is such that it allows the use of a flat ribbon cable between J3
and a PC/AT compatible DB25F parallel connector.
