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 sections 3.4 & 3.5. 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 navigating to the iCCU Configuration screen (Main Menu
→
iCCU Configuration). Select Cabinet Ped Interface.
If Using Cable A for Load Switch Monitoring:
Select the 4 Channel option. Then tap Save in the upper-right of the screen.
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 Load Switch and Ped Call Assignments.
Proceed to Assigning iNS2 PBSs to Phases in section 5.5.
