16.6 Double Serial
Interface Board, cont.
"uart2:" Confi guration
The serial communication port "uart2:" can be confi gured for 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.
Caution!
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 chapter.)
Also take care so all “legs” of the circuit fi t into their respective
slots in the socket and are not bent. Also, take proper precau-
tions so as to protect the board and circuits from electrostatic dis-
charges.
"uart2:" RS-232 (standard confi guration)
RS-232 circuit fi tted on IC2
No circuits on IC3, IC4 or IC18
Strap on S4 deactivated
