Configuring and Installing Your Module
This chapter tells you how to:
select module features by setting configuration plugs
power module input circuitry and output devices
key the module
make wiring arm connections
install the module
Electrostatic discharge can damage integrated dircuits or semiconductors
in this module if you touch backplane connector pins. It can also damage
the module when you set configuration plugs or switches inside the
module. Avoid electrostatic discharge by observing the following
precautions:
Touch a grounded object to discharge yourself before handling the
module.
Do not touch the backplane connector or connector pins.
When you configure and replace internal components, do not touch
other circuit components inside the module. If available, use a
static-safe work station.
When not in use, keep the module in its static-shield bag.
CAUTION: Electrostatic discharge can degrade performance
or damage the module. Handle as stated above.
You can choose various module features by setting configuration plugs.
The module is factory-set for use with a BCD differential output encoder.
To access the configuration plugs, lay the module on its right side and
remove the cover.
The configuration plug sockets are labeled E1 through E15 on the left
printed-circuit board and E1 on the right printed-circuit board. Locate the
configuration plugs with the board positioned as shown
in Figure 3.1 and
Figure 3.2. Each plug is inserted on two pins of a three-pin connector.
You change the position of the plugs in a left-right or up-down direction.
