Keypad
Securely framed and clamped into place, the keypad surface provides excellent splash
resistance and prevents curling or peeling of the keypad overlay. Keypad layouts include 45,
30, and 20 keys available with standard or custom graphics and 32 and 15 keys available with
custom graphics. Keypads can be made from your choice of elastomeric or membrane
material.
Switches and Indicators
You can program up to fifteen function keys (keyboard dependent) with single characters
and save in non-volatile memory.
Battery-powered TechTerms have an On/Off switch and a low battery indicator.
Interface Options
Interface options for the TechTerm include RS-232, RS-422 or CMOS/TTL protocols.
Communication (up to 9600 bps) with a host device is through a modular 6-pin connector.
Durability
Like all Two Technologies' products, the TechTerm is remarkably rugged. The case consists
of Cycolac ABS, one of the most durable, chemical-resistant materials available on the market
today.
