Changing the baud rate
The RS-232 interface can be configured from the physical controls to support faster baud
rates and to supprort a remote keypad (optional accessory). The default configuration is
2400 baud. When the generator is powered on, the baud rate returns to the default
configuration.
To support file transfers, you can change the baud rate of the port to 38400 bps using the
command line interface or 9600 bps using the physical controls.
To increase the baud rate using the command line interface:
1. At the R:> prompt, enter the following command:
MODE
38400 n, 8, 1, h, n
After you press Enter, the terminal emulator will lose its connection with the generator,
which is now set at a different baud rate.
2. Close the terminal emulator session, change the baud rate to 38400, and then re-open
the session, specifying the baud rate as 38400.
To change the baud rate to 9600 using the front panel:
1. Turn off the generator.
2. Hold down the R and DCS keys while starting the generator. The serial port is now set
to 9600 bps. Restarting the generator again, without pressing any keys, will
Sending commands interactively
This procedure describes how to send commands through an interactive user session.
The generator parses command lines one at a time. Command lines must be terminated
with a carriage return (<cr>). The generator immediately echoes each character as it is
received and places it in a command line buffer. When sending multiple commands at
once, separate each command with a semi-colon. Commands are not case sensitive.
To send single commands to the generator:
1. Establish a terminal session with the generator (see page 14).
2. At the R:> prompt, enter commands or queries and terminate with a carriage return.
