EA KIT129-6
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
16 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.
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 J1 also.
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.
RS-232 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.
The same serial data with 5V levels and CMOS 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 RxD and CTS must be
cut or opened.
Please note that the internal data buffer only holds 16 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.
