RFID 13.56 MHz Interface Board for EasyCoder F2 and F4 Printers – Installation Instructions
The serial communication port "uart2:" can be confi gured for
one of four different types of serial communication:
• RS-232
• RS-422 non isolated
• RS-422 isolated
• RS-485
By fi tting or removing certain circuits and straps, the desired
type of interface can be selected. This is either done at factory
or by the customer. There can only be one driver circuit and its
corresponding straps fi tted at a time.
When fi tting circuits yourself, do it before connecting the inter-
face board and make sure that the circuits are not fi tted upside
down (see front end markings in the illustrations in this chap-
ter.) Also take care so all "legs" of the circuits fi t 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.
