The HHDT is manufactured for Automation Electronics by Oyster Terminals Ltd. It was developed as a replacement for
the less capable DUKS unit for our pump off controllers.
Its enhanced capabilities include the transmission of the full 7-bit ASCII character set, a much larger selection of function
keys, and the ability to display dynamometer cards graphically. It responds to most ANSI VT-100 control sequences appropriate
for a hand held terminal and transmits extended codes for special function keys to allow their identification and use in the
controller.
