ComPair Cable overview v1 - 20071009 This is an overview of all cables used by the ComPair system for communication either between the ComPair interface interface and the product or directly between the PC and the product (in case of an RS232 connection). See the ComPair Cable column in the ComPair Feature List to find out which cable(s) is (are) required for which chassis.
ComPair RS232 cable (DB9 to 3.5mm Jack) 12NC: 3104 311 12742 Signal: Serial (RS232) Connect: Between PC COMM port (or RS232/ UART port on ComPair II interface) and TV

ComPair UART cable (DB9 to 2mm pitch JST) 12NC: 3122 785 90630 Signal: Serial (RS422) Connect: Between ComPair I or II interface and TV Note: When using this cable with TPT1.x, TPM1.x and QCZ1.x chassis, the brown and white wire (RxD and TxD) need to be swapped. The easiest way to do this is to use a sharp and pointed device to carefully lift the little white plastic place holders (1 and 3) in the JST connector and remove the metal parts. Then insert the brown wire where white used to be and vice versa.

This is because the capacity of the cable is too high for the I2C bus.
