Base DMX
SKU:M128
Description
Base DMX is a functional base specifically designed for DMX-512 data transmission scenarios. It communicates and enables control with the M5 host via a serial port and comes equipped with both male and female XLR-5 and XLR-3 connectors to facilitate connections to DMX devices with different interfaces. In addition, the module features a 485 interface with HT3.96 pitch for connecting to extended 485 devices. Communication signals are transmitted through high-speed opto-isolation, and the power supply adopts a dedicated isolated power module. It provides two independent RS-485 circuits for transmitting and receiving DMX data, with an internal double-pole switch allowing the operation of two independent lines or parallel connections. For power supply, the DC-JACK interface and its corresponding DC-DC circuit can power the entire device. This product is suitable for stage lighting control, sound equipment control, landscape lighting control, and decorative lighting control.

Onboard Switch Function Description
- Switch1: Controls whether the Base DMX output interface is connected to a 680Ω bias resistor. This resistor ensures stable levels on the bus during idle states and improves signal quality.
- Switch2: Controls whether the Base DMX input signal is split (signal input to the host) or bypassed directly to the output interface.
- Switch3: Controls whether the Base DMX input interface is connected to a 120Ω termination resistor. This resistor reduces signal reflection and improves signal quality.
