SELECTING A DATA TRANSFER RATE
The default data transfer rate is 1200 bps. If your
network uses a 9600 bps transfer rate, you can change
the default setting.

Note:
◆ Transmit data input sensitivity is 40 mVp-p for 1200 bps baud rate
and 2Vp-p for 9600 bps baud rate. Input impedance for both baud
rates is 10 kΩ. Using a modulator input level that is different than
these optimum specifications may result in deterioration of S/N
ratio or signal distortion, which could result in increased errors or a
complete failure to connect with other stations.
◆ The TX delay parameter on your TNC (for example, 300 ms)
should be set using your computer.
◆ Packet operation, easily affected by transmit and receive
conditions, requires a full-scale S-meter reading for reliable
communication.
