ZTH EU as MP level converter
Description
The ZTH EU is also a potential-free interface between the USB
port of a PC and the Belimo MP bus. It is used to connect the
Belimo PC-Tool directly to the MP bus or directly to a program-
mable MFT drive.
Power supply
The ZTH EU is supplied with power by the USB port. The MP bus
voltage is obtained internally by means of DC/DC converter. This
is why no external power supply is necessary.
Driver
To be able to work with the ZTH EU, a suitable driver must be
installed on the PC. The driver can be downloaded from the Be-
limo website (download section). After installation of the driver,
the ZTH EU device will log in to the PC as a virtual COM interface.
Note
For connection to USB ports of PCs and BELIMO-24 V drives
only (to safety extra low voltage SELV or US class 2 feeds).
