9.3 Set/Reset Output Contacts Command (3 9 3)
This command allows for the assertion/deassertion of the ULO1 to ULO9 logical outputs. It also provides the means to reset
the sealed in logical output contacts. Outputs denoted with an '*' are sealed in and can only be reset.
Bit = 0, Output Not Energized/No Change in Status.
Bit = 1, Output Energized/Change in Status.

Example: To send a command to clear 150G-2* and set ULO4, the following command bytes should be issued.
Set/Reset Output Byte3 = 01 hex
Status Change Output Byte3 = 81 hex
This allows a change to occur for outputs in bit position 7 and 0. Note that you can only clear '*' (sealed in) outputs.
