Channel and Phase Setup
The iCCU-S2 can obtain Ped interval information by monitoring the outputs of the load switches (via the
Cable A
harness)
or by monitoring the SDLC bus. The iCCU-C2 obtains Ped interval information via the C4 cable adapter and has
automatic source selection. Follow the appropriate setup steps below, depending on which iCCU-X2 model you have
installed, and how it is wired in the cabinet. Refer to section 3.3. The iCCU-S2 supports four phases. The system identifies
four channels, named A, B, C, and D. Each pedestrian phase will be associated with a channel.

Cabinet Ped Interface Selection
Begin by clicking on the Cabinet Ped Interface menu item under the Intersection category.
If Using Cable A for Load Switch Monitoring:
Click on the 4 Channel option, then click the Save Settings button.
The channel assignment will be determined by the wiring of Cable #4. For example, the red and brown wires belong to
channel A. With the Red wire connected to the Don’t Walk output of the ped load switch associated with phase 2, and
the Brown wire connected to the Walk output of the same load switch, channel A has a hard-wired association with
phase 2. The most common assignment is setup by default. To customize the assignment, choose the Advanced 4-
Channel Settings sub-option and then click on Advanced Settings and modify the assignment as necessary.
If using the iCCU-C2 and the cabinet input file is wired differently than the Cal-Trans standard such that the ped call
wiring in the backplane is different than the C4 connection, select the Advanced 4-Chan Settings option and tap the
Advanced Options button to change the configuration of the input file phase mapping.
