Power
The TechTerm is available as a line-powered or battery-powered unit. Line-powered units
use a 7.5-12 VDC linear regulator. A 5 VDC (
±
5%) transformer and optional 9.5-28 VDC
switching regulator are also available, depending on current draw.
Battery-powered TechTerms come equipped with a push-button power switch, low-battery
indicator and a rechargeable Nickel Metal Hydride (NiMH) battery. Operating time on a full
charge is up to 40 hours, depending on use. Battery-powered TechTerms can also operate on
six AA alkaline batteries
Display
TechTerms come with a standard 80-character monochrome liquid crystal display that
features the standard U. S. ASCII character set as dark characters on a light background.
A supertwist nematic display is available for applications that require a greater viewing
angle. For applications where ambient light is insufficient, backlit supertwist and LED
Backlight supertwist displays are available for line-powered units. Other display options for
line-powered units include a Vacuum Fluorescent Display (VFD) and an extended
temperature VFD.
