I/O chassis module slot. They also help to align the module with the
backplane connector.
Each module is slotted at its rear edge. The position of the keying bands
must correspond to these slots to allow insertion of the module. Position
the keying bands on the upper backplane connector between the numbers
at the right of the connectors. Keying bands are only used to key slot 0 of
the module. Figure 3.3 illustrates the encoder module keying positions
for slot 0.

You must provide a minimum of two external power supplies: one to
power input circuitry and one to power output devices.
Input Power Supply
Connect a +5V DC power supply for the input circuitry between terminal
21 (+) of the left wiring arm and terminal 21 (-) of the right wiring arm.
Make sure the voltage is 5V DC +.25V. The input circuitry requires a
