Figure 6 - Example for remote sensing wiring
The connector Sense is a clamp terminal. It means for the remote sensing cables:
• Insert cables: crimp sleeves onto the cable ends and simply push them into the bigger square hole
• Removecables:useasmallatscrewdriverandpushintothesmallersquareholebelowthebiggeronetoloosen
the cable clamp, then remove cable end
2.3.7 Connecting the analog interface
The optionally available 15 pole connector (Type: Sub-D, D-Sub) on the rear side is an analog interface. To con-
nect this to a controlling 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 input.
The analog interface is galvanically isolated from the device internally. Therefore do not con-
nect any ground of the analog interface (AGND) to the DC minus input 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 try to
install a driver. The required driver is for a Communications Device Class (CDC) device and is usually integrated in
current operating systems such as Windows 7 or 10. But it is strongly recommended to use and install the included
driver installer (on USB stick) to gain maximum compatibility of the device to our softwares.
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 found out by searching the Internet. With newer versions of Linux or MacOS, a generic CDC
driver should be “on board”.
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“.
