Chapter 7 - Controlling the Printer Using the Industrial Interface The optional Serial/Industrial Interface Board includes 8 digital IN ports, 8 digital OUT ports, and 4 OUT ports with relays. When used with the optional Serial/Industrial Interface Board, Fingerprint can control external equipment such as conveyor belts, gates, turnstiles, and control lamps, in addition to the printer. Conversely, the status of various external devices can be used to control both the printer and other equipment. Thus, a Fingerprint program can independently control workstations without an online connection to a host computer. There are several Fingerprint commands used in connection with the Serial/ Industrial Interface Board: • PORTOUT ON/OFF: Sets one of the OUT ports (digital or relay) to either on or off. • PORTOUT.DATAREADY ON: Asserts the Dataready signal, which can be used to control a print applicator. • PORTIN: This function returns the status of a specified port, or checks the current state of a specified input or output signal. 122 Fingerprint Developer's Guide
