J-7.5 Installing a NIC in an existing CCM Module
1. Ensure that all programming is saved using PCS software.
2. Put on a properly grounded ESD-protective wrist strap.
3. Remove power from panel but be sure the chassis remains
grounded.
4. Remove 4 nylon screws holding membrane keypad and
remove membrane by pulling it straight out of its connec-
tor.
5. Remove the 6 threaded spacers that secure the display
electronics board and lift board out. Do not disconnect board
- let it hang down. Data and power lines will remain con-
nected.
6. Insert the three plastic standoffs that were included with
the NIC into the holes shown in Fig J-5.
7. Carefully plug the NIC into the 20-pin receptacle and onto
the plastic standoffs.
8. Secure upper right corner of NIC with long screw and
spacer. Spacer will separate NIC and the CCM board and
screw will go through to the panel.
9. Replace the display electronics board and reattach the 6
threaded spacers.
10. Carefully plug in the membrane keypad and attach the 4
screws. Make sure pins and receptacle are properly aligned.
11. Attach network wiring as previously described.
12. Reinstall programming and configure the network using
PCS. See J-2.

J-7.6 Replacing Firmware Chips
For complete instructions, see PEGAsys Firmware Upgrade
datasheet (P/N 06-235763-001). This document covers the CCM
EPROM. Be sure to follow ESD prevention procedures.
J-8 POWER SUPPLY REQUIREMENTS
The NIC is powered by the panel to which it is attached via the
CCM board. No other power connections are required.
J-9 TESTING
Testing is a function of the PEGAsys system in which the NIC is
installed. No local test functions exist. For more information on
testing the NIC and the network, see the PEGAsys Configura-
tion Software (PCS) Program User's Guide.
