APCC Installation Considerations
This chapter provides the installation considerations for the APCC. Prior to
installing an APCC ensure that the following aspects have been considered in the
site design.
1. Identify the devices that will be used with the APCC (refer to
Identifying the SPP
and Sensors
).
2. Determine the configuration of the APCC (refer to
Determining the Device
Configuration
).
3. Determine the number of available slots in the traffic controller's detector
shelf and which contact closures are required (refer to
Determining Slots and
Contact Closures
).
4. Develop the sensor-to-contact closure card mappings (refer to
Mapping Wireless
Sensors to Contact Closures
).
Identifying the SPP and Sensors
SPP
Each APCC must connect to an SPP. This connection supplies power to the SPP
and passes command and configuration data to/from the APCC. There is a one-to-
one relationship between the APCC and master cards in a network.
Determine the location of the SPP relative to the cabinet that will hold the APCC
card. The Cat5 cable that connects to the SPP to the APCC, via an isolator, must
meet standard length limitations (2,000 ft with isolator) for RS422
communication.
