Model IR4000S 

 

28 

7.0 Modbus Interface 

The IR4000S does not have a built in Modbus interface. The Modbus signals from the 
single Modbus interface on the connected detector (either an IR400 or IR2100) that is 
connected to the IR4000S is passed through the IR4000S and made available as MOD + 
and MOD – on TB2. Be aware that the commands are sent directly to the IR400 or 
IR2100 detector, not the IR4000S. 

For details on the Modbus registers and a programming guide, a separate Modbus 
manual for the IR400 is available at www.MSAsafety.com/detection.
