EL512.256-H Series Operations Manual (020-0354-00A)

 

 

Two Bit Parallel Data 

To reduce the input data frequency the video data can be input two bits per 
clock cycle. The two data inputs are organized so that the data for the odd 
columns, numbered

 

from left to the right at the viewers side, is input at the

 

TVID (J1/ pin 7) and the data for the even columns at

 

VID (J1/ pin 15). The two 

bit parallel mode is selected by

 

removing  jumper 2 of the pin strip PS1. 

Display Enable 

The display can be totally shut off for screen save or power reduction by a LOW 
sate in the ENABLE control

 

input (J2/pin 6). When disabled, the display stops

 

scanning and only the DC/DC converter remains

 

functional lowering the 

power consumption to below

 

2 W. In normal operation the ENABLE input 

should be

 

pulled HIGH or left disconnected (internal pull-up). 

Brightness Control 

The brightness of the display can be adjusted (appr. between 40 and 100%) by 
an external 50 k

 Ω

 

logarithmic potentiometer between the LUMPOT1 and 

LUMPOT 2 inputs (J3/pins 1 and 2). The control function is done by feeding a 
small DC current signal via the external potentiometer from LUMPOT1 (+5V 
reference voltage) to LUMPOT2. If the two inputs are left disconnected, the 
brightness is at its maximum level. 

Low Power Mode 

The power consumption of the display is possible to

 

be reduced typically to 4 

W by using the low power mode. This mode is selected when _LOWPOW 
control

 

input (J2/5) is pulled low. In normal operation

 

_LOWPOW should be 

pulled HIGH or left disconnected.

 

In low power mode the contrast and average 

brightness

 

of the display are slightly reduced. 

Self Test

  

The operation of the display can be easily checked

 

without any external 

signals by the self test function. 

Remove Jumper 1 in pinstrip PS1.

  

Connect power to the display. 

All pixels of the display will be lit with the exception

 

of the first half of the 

topmost row.
