DKM-411 User Manual Rev_01                                                             Firmware V-1.0                     

 

 

 

K46D03-EN                                                 - 22 -                                              

 

 

Structure: 

RS-485,  isolated. 

Isolation voltage: 

1000VAC, 1 minute 

Connection: 

3 wires (A-B-GND).  Half duplex. 

Baud rate: 

2400-115200 bauds, selectable 

Data type: 

8 bit data, no parity, 1 bit stop 

Termination: 

External 120 ohms required 

Common mode voltage: 

-0.5 VDC to +7VDC, internally clamped by transient suppressors. 

Max distance: 

1200m @ 9600 bauds (with 120 ohms balanced cable) 

200m @ 115200 bauds (with 120 ohms balanced cable) 

 

 

 

 

The RS-485 port features MODBUS-RTU protocol. Multiple modules (up to 128) can be paralleled on the 
same RS-485 bus for data transfer to automation or building management systems. 

 

 

The RS-485 port provides also a good solution for distant PC connection where RainbowPlus program 
will enable programming, control and monitoring. 

 

 

For more details about programming, control and 
monitoring through RS-485 port please refer to 
RainbowPlus user manual. 

 

 

The Modbus register list is available at Datakom 
technical support.
