Installing the BASIC Module
Chapter 3
3–5
Now that you have determined the configuration, power requirements,
location, keying and wiring for your module, you are ready to install it in
the I/O chassis.
1. Turn off power to the I/O chassis.
2. Insert your module in the I/O rack. Plastic tracks on the top and
bottom of the slots guide the module into position. Do not force the
module into its backplane connector. Apply firm, even pressure on
the module to seat it properly. Note the rack, module group and slot
numbers and enter them in the module address section of the
block-transfer instructions.
3. Snap the I/O chassis latch over the module. This secures the module
in place.
You must use the following procedure when powering up the module for
the first time. This procedure is a continuation of the installation procedure
presented above.
4. Connect the cable from your program terminal to the BASIC Module
program port.
CAUTION: Be sure you properly ground the system be fore
turning on power. A difference in ground potential between the
BASIC Module serial connectors and your program terminal or
other serial device can cause damage to the equipment or loss of
module programs.
5. Turn on your program terminal. Select 1200 baud. If you are using an
industrial terminal, select the Alpha Numeric mode, baud rate and
press [RETURN].
6. Turn on power to the rack. The following sequence takes place:
Fault (FLT) and ACTIVE LED’s go on.
FLT and ACTIVE LED’s go out until power-up diagnostics is
complete. Ignore any other LED activity during power-up.
ACTIVE LED goes on.
