LCD Term 20
LCDTERM20 is the choice for all applications requiring extra features.
Displays with 4 lines of 20 characters are very common but have other character positions than the other displays. LCDTERM20 fits these displays in size and mounting holes.
- High power nonstandard version of LCDTERM
- Use LCDTERM20 instead of standard LCDTERM for:
4x20 displays. - Large displays requiring high backlight drive current.
- Large or extended temperature modules
requiring high negative contrast voltages. - Non-RS232 levels
- 4 x 20 LCD module driver software and form factor: 60x98 mm.
- Software for other modules available optionally.
900mA @ 5V backlight supply, switchable. - Contrast voltage generation -15 to +5V (for large modules).
- RS232 standard serial line, optional module socket for level shifter modules: 20mA TTY, RS422, fiber optic.

Details
There are many other applications where special features are needed: extended temperature displays (-10 to +60 °C) often need -5V to +5V contrast voltage while large displays need up to -15V. Also large 12mm character size 4x20 modules need up to 800mA of backlight current where LCD-TERM20 is the choice.
RS232 is very common, however, for extended lengths of cable 20mA or RS422 are better suited. There's an LCDTERM20 version with a module socket that seats level shifter modules for these line types. CTS handshake is not supported on these modules. See LCDTERM for standard features.
Technical data:
