settings will be lost. If possible we advise downloading the setting to the PC before proceeding with the
reset, to simplify any future reinstallation.
1. Switch off the matrix
2. Set dip 6 to ON
3. Switch on the matrix and wait until the presentation screen disappears
4. Set dip 6 to OFF.
2.3.3.4 Updating the firmware
The matrix firmware (program) can be updated when necessary.
When the firmware is updated the matrix setup is not erased. After updating, however, we advise checking
all the previous parameter settings are still correct, and if not we advise proceeding to reset the matrix and
then re-configure all the parameters.
1. Switch off the matrix
2. Connect the Personal Computer using the serial cable
3. Set dips 7 and 8 to ON
4. Run the update program
5. When updating is finished, close the program then switch off the matrix
6. Set dips 7 and 8 to OFF
7. Switch on the matrix and make sure it is set up correctly.
