distributors. RG-58 coaxial cable is recommended.
Connecting the Power
The VX uses an external power supply that is provided with the modem (Figure
3-5). To apply power to the modem, plug the five-pin DIN connector of the
power supply cable into the modem (labeled POWER). Next, plug the AC
power cord into the power supply, then into the grounded electrical outlet.
Connect the ground stud on the back of the modem to the radio system ground.
WARNING To avoid the danger of electrical shock or power loss, ensure that the power cord is
securely seated in the receptacle on the modem. This equipment is designed to work with
electrically grounded systems. The product’s AC power cord ends in a three-pole
grounding plug. Do not use a three-pole to two-pole adapter with the plug.
Verify that the outlet you intend to use is properly installed and grounded; the outlet used
must comply with the local electrical code for the country it is installed in. To ensure your
safety, only connect the power cable to a properly grounded outlet.
Pin assignments for the DIN connector can be found in Appendix A,
“Specifications.”
