R065 DMX512 / Modbus TCP converter (2 channels)

DMX512 / Modbus TCP converter (2 channels)

Modbus TCP to DMX512 convertor, for control of up to 2× 512 light sources or other DMX compatible devices. Alternatively, it works as a DMX sniffer, reading packets transmitted to a DMX bus by a DMX controller, and providing the data as Modbus TCP server registers.

Datasheet

The R065 is a Modbus TCP to DMX512 (further referred to as DMX) for control of up to 2× 512 light sources or other DMX compatible devices. Alternatively, it works as a DMX sniffer, reading packets transmitted to a DMX bus by a DMX controller, and providing the data as Modbus TCP server registers.


Applications:

• intelligent light control, control of other DMX compatible devices, such as fog machines
• integration of 3rd party devices into DMX-controlled systems
• testing and diagnostics of DMX systems

 

The R065 is a Modbus slave (server) device, receiving commands from a Modbus master (client). The client is a PLC or another supervisory system. The Modbus data are translated to DMX commands for 2 independent DMX channels and sent to the RS485 buses with DMX512-A protocol. The DMX telegram is sent immediately after writing into the Modbus registers, and optionally on a periodical basis according to the Period Modbus register setting. The period time is configurable in the range of 0.1 to 65.5 s.
At the DMX bus, the converter acts as a master device (note that there may only be one master at the bus). For the sake of simplicity, only one DMX bus is dispayed at the image below. The R065 contains two independent DMX interfaces, and can control up to 2x 512 DMX addresses.
