Pre-manufactured QCPort Interconnect Cables

To connect the D77A I/O modules together without using a QCPort backplane, use the QCPort connectors that are located at the bottom of the D77A I/O module. There are two QCPort connections next to each other. They are configured parallel with each other so that they can be daisy chained together using QCPort Interconnect cables. There are standard sizes for the QCPort Interconnect cables. These sizes are listed in the “Renewal Parts” portion of “Troubleshooting and Maintenance.”

Note: The maximum current allowed through a QCPort interconnect cable is 1 Amp. The maximum number of modules that may be daisy chained together using QCPort interconnect cables is calculated by adding the current rating of each device and keeping the total less than 1 Amp.

When making this interconnect, refer to the IT. QCPort System Install and Planning Guide (Publication No. MN05001002E) for the recommended cable and connections.
