NOTE: Transit and Receive may need to be reversed, depending on which type of
device or cable is connected. (No damage will result—attempt communication after
reversal.
With the connections in Figure 2-6 in place, plug the DB-9 connector into an appropriate
serial port on your PC.
To minimize the potential for RF interference, it is recommended to shield these wires.
Use a metal DB-9 connector and connect one end of the shield to the DB-9 shell and the
other end to the outer shell of the Smart-Trak 2 HD DB-15 connector.
CAUTION: The CAT-5 connector on the side of the Smart-Trak 2 is NOT an
Ethernet connector. It is for use with the optional Remote Pilot Module or CRN
cable. Do not plug an Ethernet cable here as damage may result.
