Godox TimoLink TRX Wireless DMX Transceiver

Foreword

Thank you for purchasing the Godox product.

The TimoLink TRX is a wireless transmitter and receiver device that combines both functions into one. It is plug-and-play and supports USB-C power supply. When used as a transmitter, it can be plugged into a DMX512 controller to remotely control lights with CRMX receiver functionality. Alternatively, it can be connected to the 'Godox KNOWLED' App to remotely control lights with CRMX receiver functionality. When used as a receiver, it can be plugged into lights that have DMX functionality but do not have CRMX receiver capability, allowing them to receive CRMX signals.
