7.3 The Distribution Connectors
The three 37 way D connectors PL2, PL3 and PL4 provide individual distribution of the Group X,
Group Y and Group Z signals respectively. This feature is primarily geared towards use with the
digital I/O group(s) of the board being used in order to connect the signals to one or more of the
additional expansion panels in the 200 Series Digital I/O family.
The EX213, EX230 and EX221 expansion panels add relay or high level logic output drivers
and isolated or high level inputs for any Digital I/O group of any board in the 200 Series Digital
I/O family. See section
1.4
for a more detailed description of these expansion panels.
7.3.1
PC236 compatibility
The pin designations of the three 37-way distribution connectors, when used with Digital I/O
group PPIX, PPIY or PPIZ, are given in Figure 7.2 below. These pin designations are
compatible with the Amplicon PCI236 Digital I/O board, which provides 24 lines of digital I/O (i.e.
equivalent to one 200 Series Digital I/O group PPIX, PPIY or PPIZ).
This makes it possible for the PCI236 board to take advantage of the features of the EX213,
EX230 or EX221 input/output panels by connecting directly to the panels via a 37-way cable.
The
±
12 and -5 Volt power supplies on the 37-way distribution connectors are
not
provided by
the host 200 Series Digital I/O board, unlike the PCI236 - only the +5 Volt supply is provided.
These additional power signals must be provided externally via the auxiliary power connector,
PL5. See section 7.4.3 for details.
