NOTE
If, alternatively, only a single transformer is available, when connecting a laptop, PC, web
browser, CL-Touch, or 3
rd
-party touch panel to the USB 2.0 Device Interface on the front of
the CIPer Model 50 controller, use an optical isolator for the USB connection or substitute an
M-Bus Mikro-Master USB (Relay GmbH, D-33106 Paderborn) for the PW M-Bus Adapter.
M-Bus Connection Procedure
1.
Install the PW M-Bus Adapter on DIN rail. Insert a screwdriver into the slot in the DIN rail clamp on
the underside of the PW and pry downward to loosen clamp until the unit snaps onto the rail.

2.
Connect the M-Bus devices to the PW M-Bus Adapter. All M+ and M- terminals are connected in
parallel in the PW M-Bus Adapter.

3.
Connect the PW M-Bus Adapter to the RS232 / RJ45 socket of the CIPer Model 50 using the
TECHTOO USB 3.0 and YIOVVOM DB9 Breakout Connector cable.
Both a USB RS-232 DB-9 male adapter (since most PCs and laptops no longer have a conventional DB-9
male jack) as well as a nifty little DB-9 female Jack with (small) screw terminals to connect wires (your cut
Ethernet cable) to the pins.
