20. Microprocessor versions and upgrades.
The Pulson 330 uses a One Time Programmable microprocessor.
The actual software version can be checked in following ways:
1. Push one keyboard key while switching on the instrument.
The intensity display shows the software version, while the timer
display shows the hardware jumper situation.
2. Open the unit . The software version is mentioned by means of a
label on the microprocessor.
20.1 The upgrade routine.
During initialising, the microprocessor compares the checksum of its
ROM with the value stored in the Eeprom. If there is a difference, an
error code is produced.
An upgrade version always has a different checksum than the old
version.
A software upgrade must be performed in following way:
Open the unit and take out the old microprocessor version.
Put in the new microprocessor and put a jumper on CON1 (Main
board).
Switch on the unit.
Upgrading is done when the ‘----’ symbols disappear and the new
software
version is displayed.
Switch off the unit, remove the jumper and close the unit.
