The Smart-House Master Generator (or Controller) is shown here

This is BH8-CTRLX but other models may also be available in different regions. This has one Rs232 interface for connection to external devices. Other models may have Rs485 and Rs232 ports

The UCM/Dupline + RS232 interface is shown. You can also plug in the AUX485 submodule in place of the Rs232 interface to connect to Rs485 interface on the Dupline.

Unfortunately the BH8-CTRLX controller has the Rs232 connections on terminal blocks instead of a standard DB9 male or female connector which means you will have to make up a cable to connect from the UCMs DB9 to the terminal blocks. Rs232 interfaces should really be on DB9 connectors

The connections for the Rs232 are
              UCM/Dupline                    BH8-CTRLX
TxD               3                                   12
RxD               2                                   13
GND              5                                   14

The Dupline Controller Rs232 interface should be set to 9600 baud and the Modbus ID should be set to 1 in order to communicate to UCM/Dupline
These details are also described in http://www.cytech.biz/ucmdupline_manual.html
