Adapter 1: Serial to M-Bus 

To communicate through the serial port directly to M-Bus adapter 1 is used. 

Connect  the  adapter  to  the  COM  port  on  the  computer  and  the  straight  module 

cable between the adapter and the RJ-12 contact on the gateway.

Adapter 2: Configuration 

When configuration is to be made via the serial port adapter 2 is used. 

Connect  the  adapter  to  the  COM  port  on  the  computer  and  the  straight  module 
cable between the adapter and the RJ-12 contact on the gateway.

Adapter 3: Ethernet to serial port 

If  the  gateway  is  being  used  as  an  Ethernet/RS232  gateway  adapter  3  is  used. 

Observe that hardware handshaking can’t be connected. 

Connect the adapter to the unit, which communication will be established and the 
straight module cable between the adapter and the RJ-12 contact on the gateway.
