DMX_Base

SKU:M128

Description

DMX-Base is a functional base specially designed for DMX-512 data transmission scenarios, communicating and enabling control with M5 host through serial port, equipped with XLR-5 and XLR-3 male and female interfaces, convenient for users to connect DMX devices with different interfaces, in addition, the module has HT3.96 pitch 485 interface to facilitate connection to Expansion 485 devices. The communication signal adopts high-speed optocoupler isolation, and the power supply adopts a special isolated power module; Two independent RS-485circuits can be used to transmit and receive DMX data, and two independent or parallel operation can be selected through the internal double-throw switch, and the DC-JACK interface and the corresponding DC-DC circuit can provide power to the entire equipment. This product is suitable for stage lighting control, sound equipment control, landscape lighting control and color lighting control.

Schematic

The role of the switch

S1: OUT port bias resistor

switch that connects the bias resistor to the OUT port.
opens when no device is connected to the IN side or when switch S2 is set to a separate configuration.
the switch is connected to the bias resistor in the left position and the bias resistor is disconnected in the right position.

S2: Split 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 used for the Pass-through configuration and the right position is used for the Separate configuration.
In a direct connect (pass-through) configuration, the signal input from the IN port is output directly from the OUT port.
In a direct-connect (passthrough) configuration, if you output a signal from the DMX module while entering a signal from the IN port, the device on the OUT port side may fail.
In the Separate configuration, the IN port and the OUT port are independent DMX signals, so it is necessary to use M5Stack to relay the signal.
In a separate configuration, return signals from devices that support the RDM standard cannot be relayed from the OUT port side to the IN port side.
If you are using a device that supports the RDM standard, select the Direct Connect (Passthrough) configuration.

S3: The termination resistance of the IN port

switch that connects the termination resistor to the IN port.
termination resistors are connected when the switch is in the up position and not when in the down position.
On when no devices are connected to the OUT side, or when switch S2 is set to be configured separately.
