Technical data

2. As you complete connections for each module, move left to the next
module.
The following numbered sections tell you how to connect each type of device.
To help you make the proper connections, each module cover has an
identifying label at the top. That label contains the module number and
option number. Table 1 lists the identifying labels for all modules you can
use on your system. Use the table to identify the modules as you connect
additional devices to your system. (Not all modules require additional
connections.)
