Note: Bits 2 and 3 are set to ʹ1ʹ by each device reset.
The cash drawer interface can be diagnosed remotely. For security
reasons, the cash drawer diagnostics mode must first be activated by
pressing an external momentary switch (SW2). The intention is for
authorized personnel to be present when the cash drawer diagnostic
tests take place.
There is only one cash drawer status signal; therefore, bit 0 is the status
of either cash drawer or both cash drawers.
