This document explains the setup of the Anytone AT-578UVIII Plus radio and the Moblinkd TNC3. There isn’t a dedicated DATA port on the Anytone AT578VUII Plus radio, so a special cable must be used.

Anytone AT-578UVIII Plus Setup

• Obtain a cable to connect from the radio microphone jack to the modem
• Set radio squelch to none (0)
• Using the radio menu
• Select “Settings”
• Select “Radio”
• Select “Other function”
• Set SPKR option to MIC (not radio)
• Set HAND to VOLT-DET (not uart)
• Connect the radio and modem

Moblinkd TNC3 Setup

• Get Moblinkd app (Android® phone, iPad®, or computer)
• Start the app and connect to the modem 
• Select audio out, change audio on the radio for the green bar with a little red at the end
• Select audio input
• Press transmit to verify the transmit light is on and the radio is normally on simplex
• Check KISS parameters and device info

This configuration may require more testing. Note that this procedure was tested using the Apple IOS and RadioMail Winlink App on an Apple iPad®.
