8 character (ASCII codes $00..$07) are presetted with " ", "±", "²",

"³", "ß", "Ä", "Ö", "Ü" and can be redefined with the command

"ESC Z n1 data...". After re-definition the presetted codes are no

longer available. It makes sense to switch off the relocation of

ASCII codes via command 'ESC U 0'.

After power-on or reset the predefined codes are avaiable again.

Example:

ESC Z $00 $04 $04 $04 $04 $15 $0E $04 $00

After that, character code $00 is defined as an downside arrow.

Note: For definition 8 data bytes are necesary.

There are up to 6 digital outputs OUT1..OUT6. They share with the solder link for address setting

(cannot be used with EA OPT-DIP6). When one or more outputs are used, the possibility for address

set is limited automatically.

Each output line provides a NPN transistor with about 50kOhm pull-up resistor; i.e. only LO level is

able to supply about 10mA. In summary current for

OUT1..OUT6 may not exceed 15mA. HIGH level is

able to source up to 100µA only. Driving a higher

load signal must be amplified by an external

transistor or MOSFET.

only the complete character set can be exchanged

Displays with Snap-In case (EA SERxx-92)

After Power-On all output are set to HIGH. Setting an output will be done by following command:

'ESC Y n1 n2'

n1: Output no. 1, 2, 3, 4, 5 or 6

n2=0: Output set to LOW (0V); n2=1: Output set to HIGH (5V); n2=2: Invert output
