3.4 Selection between Analogue Output and RS485 Interface
Configuration pin connected to GND:
• Independently of its original factory configuration, the EE872 features analogue outputs.
Configuration pin not connected:
• EE872 set to RS485 interface (option P1 in the order code): features RS485 interface.
• EE872 set to analogue outputs (option GA7 or GA11 in the order code): the RS485 interface is active
for the first 10 seconds after power on and awaits connection with the EE-PCS Product Configuration
Software. This allows for setup changes or adjustment of the EE872. If the connection to EE-PCS is
not established within 10 seconds, the device automatically changes to analogue output.
Change of the factory setup:
An EE872 set originally to analogue output can be changed to RS485 interface and vice versa using
the optional USB configuration cable and the free EE-PCS Product Configuration Software, see chapter
“Setup and Adjustment” below.
Please note: By changing the EE872 configuration, the product and the packaging label lose their vali-
dity. Please see “Relabeling in case of product configuration changes” at http://downloads.epluse.com/
