When more than one IR Receiver is required for coverage, plug one end of
the 12 meter Stereo Cable into the OUTput jack on the second unit and the
other into the INput jack on the first unit, the third into the second, and so on
down the chain. The last IR Receiver in series does not have to be termi-
nated. One Power Supply will serve up to four units in the chain. Please
contact GTCO CalComp if you require a special configuration. Contact
information is in the Appendix.
The PRS software needs to be informed where to pick up data collected
by the IR Receiver. It needs to be told which COM port the Receiver is
connected to.
1 Open the PRS application.

connected to. The Mac lists either the device, or an identifying serial
number, that each port is connected to, making it fairly easy to find the
correct connection for the IR Receiver. Windows, on the other hand, just
lists the available ports on the system. It's up to you to determine which
