Chapter
Installing the BASIC Module 1

Now that you have installed your BASIC module into the I/O rack,
you need to connect your external devices to the communication ports.
See Chapter 2 for cable pin out information.

Apply power to your I/O chassis backplane. At power up, the top six
LEDs are on. They go off one at a time as each part of the module self-test
successfully passes. If a fault occurs at power up, the LEDs give an
indication of the portion of the test that failed. Depending on how you set
jumper JW4 (page 1 -6) and if you’ve executed a PROG2 (page 10 -13),
the BASIC module powers up either executing a program or in Command
mode.
Although not required during initial power up of the module, the BASIC
module has a hard reset switch located behind the module ejector tab.
When this switch is pressed (you may need to use a pointed instrument to
press it), the BASIC module initiates a full reset. The BASIC module
reacts to this reset the same as it does when you turn on power to your I/O
chassis backplane.
