SUPPLY VOLTAGE
In the standard model, the supply
voltage of +5V is fed in via the
screw-type terminal J1. In the case
of the version for 9V to 35V
(EA OPT-9/35V), the power is
supplied via J2.
Important: It is imperative that the
polarity is correct. Even very brief
polarity reversal can damage the
entire operating unit immediately
and irreparably.
BAUD RATES
The baud rate can be set by means of the three DIP switches on the left. When
the equipment is delivered, the setting is 9,600 baud (DIP 3 ON). Please note
that the internal data buffer is only 128 bytes. The RTS handshake line must
therefore be queried (+10V level: data can be accepted; -10V level: display is
busy). The data format is set permanently to 8 data bits, 1 stop bit, no parity.

RS-232/RS-422
The operating unit is shipped with an RS-
232 interface as standard. The pin
assignment of connector J3 is then as
shown in the table on the left. J3 has a grid
of 2.54mm. If the operating unit is ordered
together with the EA OPT-RS4224 option,
special RS-422 drivers are fitted. The pin
assignment in the table on the right then
applies.
Incidentally, the same serial
data with 5V levels and
TTL logic is available at
the J5 eyelet strip. These
levels are suitable for
direct connection to a µC.
If these signals are used,
4 solder straps LB1, LB2,
LB 5 und LB 6 has to be
opened !
