TX192 OPTION
The TX-30 may be optionally supplied to transmit the AMX-192 protocol. This model transmits both LMX and
AMX simultaneously. An external power supply is included and is needed with this option. The AMX-192 output
signal is transmitted from a 4 pin, male, XLR connector located at the rear of the unit.
CAUTION: Some AMX dimmer equipment uses a 4 pin MINI-DIN connector for the control signal. That
connector is NOT wired the same as the 4 pin XLR connector. The following table provides the information
needed to make an adapter cable.

MAINTENANCE AND REPAIR
TROUBLESHOOTING
Verify the cables (a very common source of problems!).
Ensure that all system units are powered - particularly the dimmer to which the translator is connected.
Check address settings at dimmers, console, and translator. Check console patch configuration.
REPAIR
There are no user servicable parts in the unit. Internal service by other than Lightronics authorized agents will
void the warranty. If service is required, contact the dealer from whom you purchased the unit or contact the
Lightronics Service Dept..
