6. Connector
Pinouts
6.1
JP1 & JP2 Serial Port Connections
JP1 and JP2 carry the serial port signals for Serial Channel A and Serial Channel B respectively. JP1
(Serial Channel A) is the lower connector. The layout is designed to connect directly to a standard 25-
way connector as shown:
The pinout numbering conventions are
different for the two styles of connector (see
diagram). However, the pinout is arranged to
give a one to one connection to a 25-way D-
type connector when using Insulation
Displacement Connectors (IDC) and ribbon
cable.
Not all the RS232 signals defined for a 25
way connector are supported by the
BVME4000/6000. The cable assembly
should be built such that pin 1 on the 14 way
connector connects to pin 1 of the 25 way. A
14 way ribbon cable is used leaving pins 8 -
13 and 21 - 25 unconnected.
Figure 17 JP1 & JP2 Serial Port Connections
The above assumes standard RS232 drivers are fitted to the BVME4000/6000. If RS422 or RS485
interface modules are fitted refer to the RS422/RS485 INTERFACE MODULE documentation detailed
in the "A.9 RS422/485 Interface Module (on page 60)" section of this manual .
6.2
JP3 Parallel Port Connections
JP3 carries the parallel port signals, and the layout is designed to connect directly to a standard 36-
way connector as shown:
The pinout numbering conventions
are different for the two styles of
connector (see diagram). However,
the pinout is arranged to give a one
to one connection to a 36-way delta
printer connector when using
Insulation Displacement
Connectors (IDC) and ribbon cable.
Not all the signals defined for a 36
way connector are supported by
the BVME4000/6000. The cable
assembly should be built such that
pin 1 on the 26 way connector
connects to pin 1 of the 36 way. A
26 way ribbon cable is used leaving
pins 14 - 18 and 32 - 36
unconnected.
