Using the RS-232 Serial Port
The RS-232 serial port allows communication between an attached computer or
terminal and the main microcontroller of the generator. This communication link
lets you obtain information regarding calibration values, power and mode
settings, and the alarm number history of the generator. You can also use the link
when testing or calibrating the generator.
Equipment
• Phillips screwdriver
Step 1 – Establish the Communications Link
A. Turn off the generator.
B. On the rear panel of the generator, remove the screws that secure the metal
plate that covers the serial port. Set the screws and plate aside for re-
installation.
C. Connect a standard DB 9 serial cable to your computer and to the generator
serial port.
• Pin 2 is the serial output data line
• Pin 3 is the serial data input line
• Pin 5 is the reference line
D. On your computer, enter your communication program. Configure your
computer for 9600 baud, 8 data bits, 1 stop bit, and no parity.
E. Turn on the generator. Your computer displays the following information:
NOTE: # represents the software version number for the listed
microcontrollers. S represents the serial number.
VS_SC = XX
BP_SC = XX
“XX” represents smart connector codes.
