- 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.

Table 2. Channel configuration worksheet with example data (default values shown in bold)
Notes
1. Contact closure cards are addressed by the Card ID, a value dictated by the
controller or supplied by the installer.
2. Complete one worksheet for each channel.
3. Channel Holdover Setting should not be used; set it to zero.
4. The items listed in the section Other Information are not part of APCC
configuration. They are relevant to other aspects of installing and operating
the APCC.
Determining Slots and Contact Closures
Configuration of contact closure cards depends on (i) the availability of open slots
on the controller backplane and (ii) the use of any predefined functions or phases
for each slot – such as in the case of a standard CalTrans 322 shelf, where one
contact closure card and three contact closure EX cards are required (one card per
phase). Typically, a site survey of the traffic controller is required.
Shelf and slot information from the controller are used to create an identifier,
known as the Card ID, that uniquely defines an APCC in the network.
IMPORTANT!
If using an APCC with an I/O board, it is essential that there is an empty slot directly to the left of
the APCC.
