Industrial Interface Configuration
The Industrial Interface provides:
• 8 digital IN ports with opto-couplers (Opto In)
• 8 digital OUT ports with opto-couplers (Opto Out)
• 4 OUT ports with relays (Relay Out)
The Industrial Interface has no straps or circuits to be fitted or
removed. All signals are available on a female DB44 connector and
the various ports are controlled by the Intermec Fingerprint instruc-
tions PORTIN and PORTOUT ON/OFF (see Intermec Fingerprint
7.xx Reference Manual).
Digital Opto In
The status of the digital IN ports 101–108 can be read by means of
PORTIN functions. If a current is led through the opto-coupler of
the port, PORTIN returns the value -1 (true), else the value 0 (false).
