Serial Port Configuration
The serial communication port "uart2:" can be configured for four
different types of serial communication:
• RS 232C
• RS 422 non isolated
• RS 422 isolated
• RS 485 (not supported by UBI Fingerprint 7.11)
By fitting or removing certain circuits and straps, the desired type
of interface can be selected. This is either done at factory or by the
customer.
Caution!
When fitting circuits yourself, do it before connecting the interface
board and make sure that the circuits are not fitted upside down (see
front end markings in the illustrations in this chapter). Also take
care so all “legs” of the circuit fits into their respective slots in the
socket and are not bent. Also, take proper precautions so as to
protect the board and circuits from electrostatic discharges.
