NOTE: If the Model 2200 is beeping, then the 9V battery needs to be replaced.

If for some reason it is necessary to store the 2200 for more than a few months, it is

recommended that the unit be kept at a low temperature(5-10°C). Before storing for longer

than a year, it is advisable to remove the batteries from the unit; store the batteries separately

Control Port

Digital control is performed via the subminiature DB-9 connector on the instrument.

Signal Description

The output signal is turned on and off via the Gate line. The default (open circuit) condition is

a logical "1", allowing unimpeded signal transmission from input to output.

Output errors may be detected via the Error line. Normally at a logical "0", this line goes high

for at least 500ms if the output amplifier cannot drive the load satisfactorily or if the output

range were exceeded, such as trying to obtain 200V from the unit.

Since it is possible that either or both of the internal batteries will be too low to provide a

readable Error signal, it is strongly recommended that a periodic battery check be done via the

front panel button in order to ensure proper operation.

Pinout

The pins are connected as follows. Note that while this is mechanically compatible with a 9-

pin RS-232 connector, it is not electrically compatible. The 2200 is not smart enough to

understand serial communications; and for some, the slow, erratic speed of serial

communications would compromise performance
