DMX-shields



SN75176A

The DMX-shield is an add-on (or "shield") for the Arduino. It is an easy way to use the Arduino as a DMX-Master device (transmitter), just by adding the DMX-shield on the top of the Arduino. This shield is a simple circuit based around a driver chip (MAX-485 or SN 75176). The Driver Block Outputs the 3 Pins are needed for sending DMX (DMX-Pin1 -> Reference (GND); DMX-Pin2 -> Signal inversion (cold); DMX-Pin3 -> Signal (hot)). Furthermore is the Driver Block taking care of changing the Arduino signal Voltage (0V / 5V,) into the DMX signal Voltage (-2,5V / +2,5V, according to RS485). Resistor is 100 Ohm.

 

The  SN75176A  differential bus transceiver is a monolithic integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. It is designed for balanced transmission lines and meets ANSI Standard EIA/TIA-422-B and ITU Recommendation V.11.
