DATA COMMUNICATION
When the data transmission speed is set to 9600 bps,
the data signal coming from the TNC is applied exclu-
sively to the internal limiter circuitry to automatically
maintain band width.
NEVER apply data levels from the TNC of over
0.6 Vp-p. Otherwise the transceiver will not be able to
maintain the band width, and your transmitted signal
may possibly interfere with other stations.
D Using a level meter or synchroscope
When using a level meter or synchroscope, adjust the
TX audio output level (DATA IN level) from the TNC as
follows.
0.4 Vp-p (0.2 Vrms) : recommended level
0.2–0.5Vp-p (0.1–0.25 Vrms) : acceptable level
D Not using a measuring device
q Connect the TNC to the transceiver. (p. 171)
w Enter a test mode (“CAL,” etc.) on the TNC, then
transmit some test data.
e If the transceiver fails to transmit the test data, or
transmits sporadically, (TX/RX indicator doesn’t
light or it flashes):
- Decrease the TNC output level until the transmit
indicator lights continuously.
If transmission is not successful, even though the
TX indicator lights continuously:
- Increase the TNC output level.
■ Adjusting the TNC output level
■ Data transmission speed
In the FM data mode, the data transmission speed can
be set to 9600 bps, only when the data is output from
the pin 3 of the [DATA2] socket.
q Hold down [MENU] for 1 second to enter the Set
mode.
w Push [Y](F-1) or [Z](F-2) to select “9600bps
Mode.”
e Rotate [MAIN DIAL] to turn the 9600 bps mode ON
or OFF.
