1.9.6 USB port (rear side)
The USB-B port on the back side of the device is provided for communication
withthedeviceandforrmware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 on the
included USB stick and installs a virtual COM port. Details for remote control can
be found on the web site of Elektro-Automatik or on the included USB stick. A
general programming introduction for the USB port is available (date: 08-17-2016)
The device can be addressed via this port either using the international standard
ModBus 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 inter-
face module (see below) or the analog 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 back side of the device 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toconguration
page for network parameters, as well as a input box for SCPI commands.
2. TCP/IP access via a freely selectable port (except 80 and other reserved ports).
The standard port for this device is 5025. 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 back side of the device is provided for remote
control of the device via analog signals or switching conditions.
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 set-
tings 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)
In order to compensate for voltage drops along the DC cables to the load, the Sense
input (between the DC output terminals) can be connected to the load. The device
will automatically detect when the sense input is wired (Sense+) and compensate
the output voltage accordingly.
