PS 9000 1U Series • DC Laboratory Power Supply • User Manual
1.9.6 USB port
The USB-B port on the backside of the device is provided
for communication with the device and for firmware updates.
The included USB cable can be used to connect the device
to a PC (USB 2.0, USB 3.0). The driver is delivered on the
included CD or is available as a download and installs a
virtual COM port. Details for remote control can be found
in external documentation, a general programming guide,
on the web site of Intepro Systems or on the included CD.
The device can be addressed through the USB port either using the international standard ModBus protocol or by
SCPI language. The device recognizes the message protocol used automatically.
If remote control is in operation the USB port has no priority over either the analog interface or the Ethernet interface
and can, therefore, only be used alternatively to these. However, monitoring is always available.
1.9.7 Ethernet port
The Ethernet port on the backside of the device (standard
version of device only) is provided for communication with
the device in terms of remote control or monitoring. The user
has basically two options of access:
1. A website (HTTP, port 80) which is accessible in a standard
browser under the IP or the host name given for the device.
This website offers a configuration page for network param-
eters, as well as a input box for SCPI commands.
2. TCP/IP access through a freely selectable port (except 80 and other reserved ports). The standard port for this
device is 5025, default IP is 192.168.0.2. Via TCP/IP and this port, communication to the device can be established
in most of the common programming languages.
Using the Ethernet port, the device can either be controlled by commands from SCPI or ModBus protocol, while
automatically detecting the type of message.
The network setup can be done manually or by DHCP. The transmission speed is set to “Auto negotiation” and
means it can use 10MBit/s or 100MBit/s. 1GB/s is not supported. Duplex mode is always full duplex.
If remote control is in operation the Ethernet port has no priority over either the analog interface or the USB interface
and can, therefore, only be used alternatively to these. However, monitoring is always available.
1.9.8 Analog interface
This 15-pole Sub-D socket on the backside of the device
is provided for remote control of the device through analog
signals or switching conditions.
If remote control is active this analog interface can only be
used alternatively to the digital interface. However, monitor-
ing is always available.
The input voltage range of the set values and the output voltage range of the monitor values, as well as reference
voltage level can be switched in the settings menu of the device between 0-5 V and 0-10 V, in each case for 0-100%.
1.9.9 Sense connector (remote sensing)
During constant voltage operation (CV) and in case the adjusted output voltage has
to be held constant on the load and not on the power supply’s DC output, remote
sensing can be used to compensate for the voltage drop on cables up to a certain
limit. The maximum possible compensation is given in the technical data.
