TBS Tracer Manual
OSDs with only analog rssi input
RSSI/LQ
Combines the LQ and RSSI and translates them from 0 -100% to a PWM signal from 1000µs to 2000µs. The
RSSI/LQ value will always show the worse value of both
Smart Audio
SmartAudio is a protocol developed by TBS for OSD to VTx communication. SmartAudio is a single-wire
UART protocol, running over the (Audio)-wire. All versions of Smart Audio are supported.
Channel map
The channel map menu is almost like the output map, except that you can change the channel order which
also affects the channel order for any serial protocol. If you own a radio without flexible channel mapping,
you can do it here.
This is also used to inject the LQ sensor for your FC. An example can be found in this section.
The possible settings:
● Channel 1-12: Any channel coming from the remote
● LQ: same as the output map setting
● RSSI: same as the output map setting
● RSSI/LQ: same as the output map setting

Channel number
The transmitted number of channels. Can be set to 8 or 12 channels.
Use the 8 channels setting whenever you can. This ensures the best performance for your rc link.
