ETTINGS
Refer to Table C and Fig. 2 or 3 (per your unit) for specific infor-
mation to set the switches. Here are some general guidelines that
apply to
both
versions of Smart MAC:
Card Address
Switches S1-1 through S1-3
The MAP uses this card address to sequence up to four MACs in
an alarm system. The address also defines the ports the Smart
MAC supports. For example, Address 1 supports ports 1-8; Address
4 supports 25-32.
Master Port Data Rate
Switches S1-4
Unless system requirements dictate otherwise, set the master port
data rate for 9600 baud.
Master Port Protocol
Switches S1-5 through S1-8
Unless system requirements dictate otherwise, set the master port
protocol to DCPF.
Port Termination (SMT Version Only)
The individual bits on S3 set the termination on the receive ports.
Refer to the Port Termination section discussed earlier.

OUNTING
Determine the proper shelf slot where the module will be installed.
Slide the module along the guide slots in the equipment housing,
then firmly seat the edge connector in its receptacle.
Normally the 56-pin edge connector for the slot is prewired at the
factory. To wire the connector, refer to Fig. 4 for module connector
pin wiring assignments. Also refer to Fig. 1, the functional sche-
matic, if necessary.
