Header 217: Request payout high / low status
Transmitted data :
<none>
Received data :
[ level status ]
This command returns the status of the level sensor.
[ level status ]
Bit mask :
Bit 0 - Low level sensor status ( 1 = lower than low level trigger )
Bit 1 - High level sensor status ( 1 = higher than or equal to high level trigger )
Bit 2 - not used
Bit 3 - not used
Bit 4 - Low level sensor support ( 1 = feature supported and fitted )
Bit 5 - High level sensor support ( 1 = feature supported and fitted )
Bit 6 - not used
Bit 7 - not used
For the operator…
Bit 0 is set if the hopper is NEARLY EMPTY.
Bit 1 is set if the hopper is NEARLY FULL.
The normal operating condition of the hopper is bits 0 & 1 clear.
If the raw level sensor inputs are reading NEARLY EMPTY as well as NEARLY FULL then
this is an illegal condition (it can only be one or the other) and bits 0 & 1 are both left clear.
The level sensor inputs are debounced with a time Tlevdeb in Appendix B to remove the
effects of shifting coins.
