The RGA COM Utility
The RGA Com Utility is a simple Windows™ OS communication program that allows you to
communicate with the RGA ECU directly by typing valid RGA commands on your keyboard. The
program functions like any common terminal program where the typed characters are sent directly to the
serial communications port and any received characters are displayed immediately on the screen.
The RS-232 communication parameters of RGA Com are fixed to be compatible with the RGA ECU.
The only variable that may be selected is the communications port. A list of up to nine com ports is
available to connect to the RGA ECU.
RGA Com Fixed parameters:
•
28.8k Baud rate
•
8 Data bits
•
No Parity
•
2 Stop Bits
To connect to an RGA ECU do the following:
1. Start the RGA Com program.
2. Select the “Select Com Port...” command from the “COM port Setup” menu.
3. Select the Com port you want (usually COM2) from the list box and press OK.
4. Select the “Connect” command from the “COM port Setup” menu.
5. Begin typing commands, press “Enter” after each command to validate it.
6. When you are done select the “Disconnect” command and exit the program
Tip
•
When you first connect to the ECU (step 5 above), send the ID? command to verify the
connection with the RGA ECU. This command will return the model number, serial
number, and firmware version of the RGA unit you are connected to.
Important
•
If you make typing error the RGA’s Error LED will blink. Press “Enter” and retype the
command, the Backspace character is not processed.
•
When you are done using RGA Com you must disconnect the COM port or exit the
program, otherwise no other Windows program can communicate with the open COM
port.
