WARNING
!
Danger of explosion!
The Dräger REGARD 3900 Modbus Gateway V2.0 is not designed or authorised for
use in areas where flammable or explosive gas mixtures could develop.
The REGARD 3900 Modbus Gateway V2.0 is needed for the communication between the con-
trol unit REGARD 3900/3910 and the visualisation panel RVP 3900.
The visualisation panel receives data from up to 8 control units and displays them in a graphical
form. Every system needs its own REGARD 3900 Gateway. The gateway transforms the CAN
bus data from the REGARD 3900/3910 in to the Modbus protocol. This Modbus data is needed
for the visualisation of the REGARD 3900 System.
Before using the REGARD 3900 Modbus Gateway V2.0 it has to be addressed.
The addressing is carried out via DIP-Switches on the front side of the gateway.
