Overview of QCPort Interconnect System
Device Connection in a QCPort System
Devices are connected into a QCPort system using one of the following connection
types—either a backplane or interconnect cabling. Both of the connection types provide
for communication and power.
types—either a backplane or interconnect cabling. Both of the connection types provide
for communication and power.
The entire QCPort system, using QCPort pre-manufactured interconnects, cannot exceed
100 feet [30 meters] in total length. For systems that require longer runs, the long run
interconnect is used. Using the long run interconnect, the system length is increased to
500 feet [150 meters] @ 460Kbaud and 1000 feet [300 meters] @ 230Kbaud. In this
case, special care has to be taken to size the power supply correctly for the distance.

QCPort Backplane
The QCPort backplane provides a convenient way to connect the Network Adapter and
IO devices that are located in close proximity to one another. The QCPort backplane
mounts within a DIN rail, allowing the receptacles on the back of the Network Adapter
and IO products to plug into them. This auto connection eliminates the need for any
customer communication or power wiring between devices, while providing hot insertion
and removal without affecting other devices.

The QCPort backplane provides the data signals and the 24V DC to power all devices
that are connected. The QCPort backplane is limited to a maximum current carrying
capacity of 6 amps.
