- 1. Cabling – a minimum of one straight-through Ethernet cables are required.
- 2. Laptop PC and TrafficDOT software – if contact closure cards will be configured via TrafficDOT's GUI, a suitable host is required.
- 3. Contact closure card functions can be configured from the switches on the front panel eliminating the need for a laptop PC and TrafficDOT.

Wireless Sensors
Each channel of an APCC interfaces a designated set of sensors to a designated
contact closure. Ensure information describing which sensor (or sensors) will
actuate a given APCC is available.
NOTE:
Wireless sensors have a unique identifier known as the Sensor ID. Use this identifier to
refer to sensors in design notes and plans.
Determining the Device Configuration
Configuration of an APCC is based on the following design decisions:
The number of APCC channels enabled
The operating mode (pulse or presence) of each channel
The use of and settings for any optional elements that modify the behavior of
channels operating in presence mode
The channel status communication method (LED-only) used by each channel
Configuration Worksheet
Each APCC supports up to four channels that are separately configured. Design
decisions can be captured in a Channel Configuration Worksheet such as the one
shown below.
NOTE:
Default values are shown in bold.
