operating as expected.
Point-to-Point Network Quick Start (HyperTerminal):
1. Connect antennas to the transceivers.
2. Connect the transceiver to the serial port of a computer either through a serial cable or using the
diagnostics cable. Make sure to connect the radio to a power source (+6.0 to +27.0 VDC).
Warning!

not
connect the LRS-455 series radios to DC power without terminating
the antenna port to a suitable load, such as a 50 ohm antenna, or an
attenuator with a power rating greater than or equal to 2 W. Powering up
without a load attached will damage your radio and void your warranty.
