The USB-B 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 on the included CD and installs a virtual COM port. 

Details for remote control can be found on the web site of Elektro-Automatik or on the included 

CD. A general programming introduction for the USB port is available (date: 01-15-2015) 
The device can be addressed via this port either using the international standard ModBus pro-

tocol 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 alternatively to these. 

However, monitoring is always available.

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 AnyBus CompactCom 

(abbr.: ABCC) type of the IF-AB interface series. The following options are available 

(date: 01-15-2015):

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.

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 val-

ues, 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%.
