Description
The EasyReader-S accepts numeric serial ASCII data and displays it on a 4 digit LED readout. The
digits are 57mm or 102mm high, depending on model.
It can accept a limited range of alphabetic characters - limited by their ability to be represented
accurately on a 7 segment type display.
Its string extraction ability allows the display to select defined parts of a data string for display,
whilst rejecting surrounding data.
The front panel comprises of a 4 digit LED display, including decimal points and minus sign.
All adjustments are made with front panel pushbuttons.
A lockout connector allows you to disable the front panel programming buttons, to protect settings.
An unlocked display won’t perform parity checking or addressing. Every character which arrives
will be displayed as it arrives - a useful feature for diagnostic tests.
The characters may be made to flash if you include CtrlF in the datastring.
You can change the brightness of the display to one of 6 levels. To do this, press the DOWN
arrow button for more than 3 seconds and wait until the display brightness suits your environment.
The display will store the chosen brightness level, so that it will return to this brightness if power is
lost and re-applied.
