A unit address planning worksheet is provided in Appendix A - Unit Address
Worksheet that allows you to record the unit addressing information for your
comparator display system. Using the system shown in Figure 7 as an example,
the worksheet would look like the following:
Unit Type Group # Module # Bank
Group & Module # of
associated
Comparator I/O
Module
(For IIB only)
Group: Module:

CIB 01 0 0 Comparator #1 Room A
CIB 01 1 0 Comparator #2 Room A
CIB 01 2 0 Comparator #3 Room A
AIB 02 0 0,1 Comparator #4 Room B
AIB 02 1 0,1 Comparator #5 Room B

HIB/RCD 80 1 0 PC #1 Dispatch Room
HIB/RCD 81 0 0 PC #2 Maintenance Site
HIB/RCD 81 1 0 PC #3 Maintenance Site
* You must set the Bank # on the IIBs. CIBs and HIBs are factory-configured for
Bank 0 only. AIBs are factory-set for Banks 0 and 1.
With this worksheet, you now have a record of your MCN system configuration,
which can help reduce system troubleshooting time.
7.2 Grounding
A chassis ground connection is available on all MCN modules. This connection
point is provided by a screw hole that is marked on the bottom of the case.
CAUTION
Make sure that the screw used for grounding and mounting does not protrude into
the enclosure more than 1/8 inches from the bottom surface of the module.
Using a larger screw that touches the PC board inside the module may damage the
module when it is powered. Doing so will void the unit’s warranty.
