INTERFACE OF PACKET TNCS

The VX-177may be used for Packet operation, using the optional CT-91Microphone Adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail- able connectors wired to your TNC. You may also build your own cable, using a four- conductor miniature phone plug, per the diagram below.

The audio level from the receiver to the TNC may be adjusted by using the VOL knob, as with voice operation. The input level to the VX-177from the TNC should be adjusted at the TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms.

Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver.

When you are operating on Packet, switch the Receive Battery Saver OFF, as the “sleep” cycle may “collide” with the beginning of an incoming Packet transmission, causing your TNC not to receive the full data burst. See page 62 for details regarding Battery Saver setup.
