Command Controls (41,022)
The command control word is used to control the unit. Each bit gives access to a command or
state as if the operator was using the keypad.
Bits initiating a command (7-12) must change state to cause the command the begin. For
example, to reset totalizer 1, Bit 9 must be set to 0, then changed to 1. It can stay set or clear for
any period:
