Start-up procedure
Install the bmcm driver package (see chapter 5.1.1). Plug the red frames onto the short sides of the device
with the feet looking downward as to be seen in the product picture. Connect one end of the USB cable to the
device and the other to the USB-interface of the PC and start the Plug&Play installation (see chapter 5.1.2).
The device is supplied with power via the USB-connection.
If necessary, further software components can be installed now, as described in chapter 5.

Analog inputs and outputs
The 37-pin D-Sub female connector at the front of the device is
designed for the connection of the analog inputs and outputs. An
auxiliary voltage (e.g. for sensor supply) is provided at pin 17.
The following table shows the pin assignment of the 37-pin
D-Sub connector:

The max. potentials to ground must not exceed
±
12V. Any
channel overload may influence measurements of other
channels and may lead to wrong values.
The internal connection of the 16 analog inputs is provided via
two 16-way pin connectors P8, P9 (see figure on the right) on
the USB-AD12f board, which for example can be used for
connecting current shunts (available as accessory under:
ZU-CS250R
).
The pin assignment of these connectors is listed in the
following table:
