4.1 Polarity Reversal

The output polarity can be easily selected through jumpers on pins 9, 10 and
11 of the DSUB connector.
When pins 9 and 10 are jumpered together, the output is non-inverted. The
output is held at ground when the pulser is not gated (i.e. the TTL gate is low).
When the TTL gate is high, the output of the pulser is connected to the
potential of the high voltage DC power supplies. This is shown in the figure
below:
