9.2.6 J400 CHUC - VIP and DEK Interface
J400 is located on the back of the O5 control head assembly in the remote mount configuration. This
connector provides the ability to utilize up to 3 VIP OUT, 3 VIP IN, the GND and SWB+ pins they
require, or DEK signal lines. This connector has cable detection pins to allow the control head to
determine which type of cable is being used, and therefore allow the control head to configure its
pins appropriately for either VIP or DEK accessory interfacing. It is not recommend to fabricate this
cable from scratch. The cable must be inserted prior to control head power-up. Please refer to the
installation manual for ordering part numbers for either the VIP or DEK cable.
