EA KIT160-7
BAUD RATES
The baud rate can be set by means of the 3 DIP switches on the left. 9,600 baud
is set at the factory (DIP 3 ON). Please note that the internal data buffer only holds
24 bytes. It is therefore imperative that the RTS handshake line be queried (a level
of +10V means data can be accepted; a level of -10V means the display is busy).
The data format is fixed at 8 data bits, 1 stop bit and no parity.
WRITE PROTECTION FOR PROGRAMMED MACROS
You can use DIP switch 6 to prevent the programmed macros,
images and fonts from being inadvertently overwritten.
RS-232/RS-422 CONNECTION
The graphics kit is shipped with an RS-232 interface as standard. The pin assignment of the plug
connector (J3) is as shown in the table on the left. The J3 has a 2.54mm grid. If the graphics kit is ordered
together with the EA OPT-RS4224 optional component, RS-422 drivers are fitted. In this case, the pin
assignment is as shown in the table on the right.
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. However, if these signals are used, solder link LB5 and LB6 must
be cut or opened.
SUPPLY VOLTAGE / EA OPT-9/35V
In the standard model, the supply voltage of +5V
is fed in via screw-type terminal J1. In the case of
the version for 9..35V (EA OPT-9/35V), the
power is supplied via J2.
Important: It is imperative that the polarity is
correct. Polarity reversal, even for a very short
time, can cause the immediate destruction of
the entire display.
