Pin layout for Edge Finder, and Measured Value Output input (for
pinout)
Pins 12, and 14 are used in conjunction with the Measured Value
Output feature. When either of these contacts are shorted to Pin 8
(0V) the measured values as defined in Job Setup are output over the
TXD line of the RS-232 interface. A commercially available switch can
be used to provide the contact between pin 12, and 8. The pulse input
between pin 14, and pin 8 can be initiated with a TTL logic device (i.e.
SN74LSXX).
The operator must enter new edge finder settings.
