RS 232C:
There are no straps for controlling the RS 232C interface on
"uart3:".
External +5V:
External +5V ( max. 200 mA) can be made available on pin 16 by
fitting a strap on P-1.
Be careful not to enable this option unintentionally, which may
cause harm to the connected terminal, computer or other device.
IN/OUT Connector
In/Out port 201-204:
One relay for each port switches the OUT signal to open or closed
as PORTOUT ON/OFF statements are executed in the program.
Four straps, P-2, P-6, P-7 and P-8, control the relation between
relay and output signal on output ports 201–204 respectively:
PORTOUT stmt Strap between pins OUT signal
PORTOUT (<nexp>) ON 1–2 (upper position) Open
PORTOUT (<nexp>) ON 2–3 (lower position) Closed
PORTOUT (<nexp>) OFF 1–2 (upper position) Closed
PORTOUT (<nexp>) OFF 2–3 (lower position) Open
