Base DMX
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 is equipped with XLR-5 and XLR-3 male and female connectors, making it convenient for users to connect DMX devices with different interfaces. Additionally, the module features a 485 interface with HT3.96 spacing, allowing for easy connection to extended 485 devices. The communication signals are isolated using high-speed optocouplers, and the power supply uses a dedicated isolated power module, providing two independent RS-485 circuits for transmitting and receiving DMX data. The internal double-throw switch allows users to choose between two independent or parallel operation modes. For power supply, the DC-JACK interface and the corresponding DC-DC circuit provide power to 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
S1: OUT Port Bias Resistor
- A switch that connects the bias resistor to the OUT port.
- Open when no device is connected to the IN side or when switch S2 is set to separate configuration.
- The left position of the switch connects the bias resistor, and the right position disconnects it.
S2: Separate or Pass-through
- This switch selects whether the wiring between the IN-OUT ports is directly connected or separated.
- The left position of the switch is for Pass-through configuration, and the right position is for Separate configuration.
- In Pass-through configuration, the signal input from the IN port is directly output from the OUT port.
- In Pass-through configuration, if a signal is output from the DMX module while a signal is input from the IN port, devices on the OUT port side may malfunction.
- In Separate configuration, the IN and OUT ports are independent DMX signals, so the M5Stack is needed to relay the signal.
- In Separate configuration, return signals from devices supporting the RDM standard cannot be relayed from the OUT port side to the IN port side.
- If you are using devices that support the RDM standard, choose the Pass-through configuration.
S3: IN Port Termination Resistor
- A switch that connects the termination resistor to the IN port.
- The termination resistor is connected when the switch is in the up position and disconnected when in the down position.
- Open when no device is connected to the OUT side or when switch S2 is set to separate configuration.
