Part No. 001-4008-101/102

Rx / Tx Frequency

Rx / Tx Frequency shows the current transmit frequencies.

F5

Pressing the F5 key will cause the unit to transmit on the programmed transmit frequency.

F6

Pressing the F6 key will cause the unit to go to receive on the programmed receive frequency.

2.4.14 ASCII / Hex Terminal

Terminal Screens allow the user to select an ASCII or Hexadecimal Terminal Screen for the Primary and 
Secondary COM Ports (configured in the Port Settings screen - see Section 2.4.3) Data is sent according to 
the port configuration set up in the Port Settings screen.
