Detail
Select trigger input source as the expansion input #1 on the
comparator unit
Select trigger input source as the expansion input #2 on the
comparator unit
Disable the received light filter
Enable the received light filter
Set 1 to the number of eliminating maximum and minimum value
in the received light filter
Set 2 to above
Set 3 to above
Set 4 to above
Set 6 to the number of received light values in the received light
filter. The result of received light filter is sum of ((FILTA -
FILTE)*2+4) times of received data
Set 8 to above
Set 10 to above
Set 12 to above
Set the gain of operational amplifier #2

Specify the emitter light pulse width. Time period is
50ns*(EMITW+1). It should be set greater than 15
Specify the emitter light cycle. Time period is the emitter pulse
width×(ECYCLE+1). It should be set greater than 4.
Display switching noise may affect on the setting value is 5,37,69,
or 101
Put forward the emitter light pulse. Set value that is calculated
(EMITW-[time period].
