RS-232 INTERFACE
If the display is wired as shown below, the
RS-232 interface is selected. The pin
assignment is specified in the table on the
right.
The RxD and TxD lines lead 5V (CMOS level)
to a microcontroller, for example, for direct
connection.
If “genuine” RS-232 levels are required (e.g.
for connection to a PC), an external level
converter (e.g. MAX232) is required.
BAUD RATES
The baud rate is set by means of pins 6, 7 and 8 (baud 0 to 2). The
data format is set permanently to 8 data bits, 1 stop bit, no parity.
RTS/CTS handshake lines are not required. The required control is
taken over by the integrated software protocol (see pages 8 and 9).

Note:
The pins BAUD 0 to 2, ADR 0 to 2, WUP,
DPROT and TEST/SBUF have an internal
pullup, which is why only the LO level
(0=GND) is to be actively applied. These pins
must be left open for a Hi level.
For RS232 operation (without addressing) the
pins ADR 0 to ADR 2 must be left open.
On pin 20 (SBUF) the display indicates with a
low level that data is ready to be retrieved from
the internal send buffer. The line can be
connected to an interrupt input of the host
system, for example.
