2.3.7 Connecting the analog interface
The 15 pole connector (Type: Sub-D, D-Sub) on the rear side is an analog interface. To connect this to a control-
ling hardware (PC, electronic circuit), a standard plug is necessary (not included in the scope of delivery). It is
generally advisable to switch the device completely off before connecting or disconnecting this connector, but at
least the DC output.
The analog interface is galvanically isolated from the device internally. Therefore do not
connect any ground of the analog interface (AGND) to the DC minus output as this will
cancel the galvanic isolation.
2.3.8 Connecting the USB port (rear side)
In order to remotely control the device via this port, connect the device with a PC using the included USB cable
and switch the device on.
2.3.8.1 Driver installation (Windows)
On the initial connection with a PC the operating system will identify the device as new hardware and will install
the driver. The driver is a Communications Device Class (CDC) type and is usually integrated in current operating
systems such as Windows 7 or XP and is therefore not provided additionally. There are, however, versions such
as Windows 7 Embedded in which the class of driver is not installed or does not function.

(Windows 7) and the driver may possibly not be fully installed. In this case take the following steps:
1. In Windows Device Manager click with right mouse button on the not fully installed hardware. Select “Update
driver”.
2. Windows will ask if the driver should be automatically searched or whether it should be located and installed
manually. Select the latter (second choice in the dialogue window).
3. In the next dialogue window the driver source path will be determined. Click on “Search” and enter the folder
of the USB driver from the “Drivers & Tools” CD or the path to the downloaded and unpacked driver. Allow
Windows to install the driver. A message that the driver is not digitally signed can be submitted with “Ignore”.
2.3.8.2 Driver installation (Linux, MacOS)
We cannot provide drivers or installation instructions for these operating systems. Whether a suitable driver is
available is best carried out by searching the Internet.
2.3.8.3 Alternative drivers
In case the CDC drivers described above are not available on your system, or for some reason do not function
correctly, commercial suppliers can help. Search the Internet for suppliers using the keywords “cdc driver windows“
or “cdc driver linux“ or “cdc driver macos“.
