Industrial Interface Confi guration
The Industrial Interface provides:
• 8 digital IN ports with optocouplers (Opto In)
• 8 digital OUT ports with optocouplers (Opto Out)
• 4 OUT ports with relays (Relay Out)
The Industrial Interface has no straps or circuits to be fi tted or
removed. All signals are available on a female DB-44pin connec-
tor and the various ports are controlled by the Intermec Fingerprint
instructions PORTIN and PORTOUT ON/OFF (see Intermec Fin-
gerprint v7.61, Programmer’s 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.)
