6.4 REMOTE COMMUNICATIONS
The converter can be controlled remotely and be queried for alarm, electrical, and status data
through its RS-232C port. The port’s hardware configuration is by default RS-232C unless modified
by the inclusion of the Modbus Option—which converts the default hardware protocol to the RS-485
standard via a din-rail mounted converter/optical-isolator.
The two software protocols supported by the converter are SCPI and Modbus. Please contact an
ASEA Power Systems authorized distributor or the factory for additional information and
comprehensive command/query listings.
The Baud Rate and fixed serial port settings can be viewed in the REMOTE INTERFACE
CONFIGURATION display (as depicted below) by pressing the CONVERTER POWER (6) and
SYSTEM STATUS (7) buttons simultaneously, and then pressing the Comm (SHORE POWER)
button. The software protocol in use is indicated in the lower-right corner (SCPI or Modbus) of the
display. The software protocol is auto-detected by the converter based on the incoming
command/query formatting.
The Baud Rate can be increased by pressing the Press the More (SHORE POWER) button, and
decreased by pressing the Less (CONVERTER POWER) button. Press the SCPI/Modbus (F2)
button to manually move between the SCPI and Modbus modes. Press the Cursor (F1) button to
change the Node Id while the m ode is set for Modbus. Press the Exit (SYSTEM STATUS) button
to save settings and exit. Standard baud rates are 1200, 2400, 4800, 9600, 19200, and 38400 where
19200 is the standard for communication with ASEA Power Systems Touch Screens.
