Function description 

The RESI-DMX-ASCII converter is designed to integrate a DMX light subsystem into an automation device 
very  easily.  The  automation  device  has  to  offer  a  serial  interface  (RS232  or  RS485),  which  is  capable  of 
sending and receiving simple ASCII messages. The  converter also offers the possibility  to control  the 512 
DMX lights via a MODBUS/RTU based serial interface of an automation device, because the converter is also 
a MODBUS/RTU slave. The RESI-DMX-MODBUS converter is designed to control a DMX light system with 
MODBUS/RTU protocol. 
  
The bases for this integration are lamps with ballasts, which are compatible to the DMX standard. 
 
Please refer to the DIN 56930-2, ANSI E1.1 norm for more operational details about the DMX light system. 

 

If the converter works properly, the state LED flashes with a 1 second period. Is there an internal error in the 
converter, then the state LED flashes with a 250m period. 
 
Is the DMX connection ok and the converter is cyclically sending data to the DMX lamps, the DMX LED  is 
always on. If the user has stopped the cyclic sending of DMX data, then this LED flashes faster with 250ms 
cycle.   
 
For the communication with ASCII strings, the ASCII messages starts with a special start character # (0x23, 
35dec)  and  the  message  ends  with  a  special  end  character  (0x0d,  13dec  or  CARRIAGE  RETURN).  The 
answer of the converter uses the same start and end characters. Please refer the chapter ASCII command 
description. 
 
For communication via MODBUS the following MODBUS functions are available: 
 

  READ HOLDING REGISTER (function code: 3) 

  PRESET SINGLE REGISTER (function code: 6) 

  PRESET MULTIPLE REGISTERS (function code: 16) 

 

Note: 

The functions READ HOLDING REGISTER and PRESET MULTIPLE REGISTERS are limited to max. 50 register 

per query! 

 
 
More information about the MODBUS/RTU slave functionality see the chapter MODBUS Registers.
