PSB 9000 3U Series
2.3.10 Connecting the “Share” bus
The “Share” bus connector on the back side is usually connected to the Share bus connectors of further units of
series PSB 9000 3U, in order to balance the current between multiple units in parallel operation, especially when
using the integrated function generator of the master unit. For further information about parallel operation refer to
section
„3.12.1. Parallel operation in master-slave (MS)“
For the connection of the share bus the following must be paid attention to:
•
Connection is only permitted between compatible devices (see
for
details) and between a max. of 16 units
•
When not using one or several units of a system configured with Share bus, because less power
is required for an application, it is recommended to disconnect the unit’s from the Share bus,
because even when not powered they can have a negative impact on the control signal on the
bus due to their impedance. Disconnection can be done by simply unplugging them from the
bus or using switches in the positive line.
•
The Share bus of this series works in two directions, for source and sink mode. It is compatible
to a few other device series, but it requires careful planning of the entire system, if devices are
going to be connected which solely work as sink (el. load) or as source (power supply).
2.3.11 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.
2.3.11.1 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.
2.3.11.2 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.
2.3.11.3 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“.
2.3.12 Initial commission
For the first start-up after installation of the device, the following procedures have to be executed:
•
Confirm that the connection cables to be used are of a satisfactory cross section!
•
Check if the factory settings of set values, safety and monitoring functions and communication are suitable for
your intended application of the device and adjust them if required, as described in the manual!
•
In case of remote control via PC, read the additional documentation for interfaces and software!
•
In case of remote control via the analog interface, read the section in this manual concerning analog interfaces!
2.3.13
Commission after a firmware update or a long period of non-use
In case of a firmware update, return of the equipment following repair or a location or configuration change, similar
measures should be taken to those of initial start up. Refer to
Only after successful checking of the device as listed may it be operated as usual.
