6.6 Remote Control Commands
The front panel keys and their associated ASCII chars are given by the diagram below. Sending these characters to the 630 has the
same effect as pressing the associated button on the front panel.
Tip: To familiarize yourself with the remote operation of the 630, it is helpful to run a terminal program on your PC and manually
type the commands and watch the response. To get a help menu, press H. See section 6.3 for details.

Figure 6.6-1: Front panel keys to ASCII command mapping
Note: Turning the rotary knob clockwise has the same effect as pressing the é key multiple times. Turning the rotary knob
counter-clockwise has the same effect as pressing the ê key multiple times.
In addition to the above ASCII command characters, extra commands are available for remote control operation. They are:
A - Reset the unit to Sinewave mode
V - Report hardware and software versions
K1,0 - Enable, Disable front panel keys and knob
E1,0 - Enable, Disable LCD echo to terminal
F0-9 - Move cursor to field 0 to 9
? or H - Print help menu
^E
- Returns ^C
Each of these "extra" remote control commands is discussed below:
A
- Reset 630 to Sinewave mode
This command resets the 630 to the Sinewave mode and turns the cursor off. The output offset voltage is set to 0.0V. When
writing control software for the 630, it is a good idea to issue this command first so that the 630 is in a known state before further
commands are issued.
Note: The frequency and level values are not reset. They are set to the values that existed the last time the unit was in Sinewave
mode. (Or the power-up default values if they hadn't been changed). The RS232 baud rate remains unchanged.
