Packet Mode Setting

1. Press the FUNC key. While [F] icon is on, press

the H/L and SQL keys. [TNC] lights up on the

display and the unit enters packet mode.

By the same operation, [TNC] disappears, the

unit exits from packet mode and the display

returns to its normal status.

2. Use the computer keyboard to send designated

commands from your PC to start packet com-

munication.

Please use PC commands to program the following.

Data Speed (Transfer Rate) : 9600bps

•What is programmed from a PC is stored in memory even after the TNC unit is

removed from the transceiver.

• This TNC unit is not equipped with all the functions an external TNC may have

(Some functions may be limited).

IMPORTANT: • Packet communication is easily affected by the transmission and re-

ception environment especially in the 9600bps packet mode, commu-

nication error may easily occur unless all segments of the S-meter are

displayed.

• While in the packet mode or geolocating communication mode, tones or

codes are not output even if a Tone setting or a DCS setting is programmed.
