PSI 9000 2U Series
1.9.7
USB port (rear side)
The USB port on the back side 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 or 3.0). The driver is delivered with the device and installs a
virtual COM port. Details about remote control can be found in form of a programming
guide on the included USB stick or on the web site of the manufacturer.
The device can be addressed via this port either using the international standard
ModBus RTU protocol or by SCPI language. The device recognises the message
protocol used automatically.
If remote control is in operation the USB port has no priority over either the interface
module (see below) or the analog interface and can, therefore, only be used alterna-
tively to these. However, monitoring is always available.
1.9.8
Interface module slot
This slot on the back side of the device (only with standard models, units with option
3W installed are different) is available for various modules of the IF-AB interface
series. The following options are available:

The modules are installed by the user and can be retrofitted without problem. A firmware update of the device may
be necessary in order to recognize and support certain modules.
If remote control is in operation the interface module has no priority over either the USB port or the analog interface
and can, therefore, only be used alternately to these. However, monitoring is always available.
Switch off device before adding or removing modules!
1.9.9
Analog interface
This 15 pole Sub-D socket on the back side of the device is provided for remote
control of the device via analog and digital signals.
If remote control is in operation this analog interface can only be used alternately to
the digital interface. However, monitoring 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%.
