Issue 4.5 August 2005 Hand-Held Terminal (HHT) 10-3
HHT OVERVIEW
The infrared hand-held terminal (HHT) is a compact, battery operated device for use with the 3GS system.
You use the HHT to communicate with the nodes on the system and to extract information such as input and output
status, voltage and current draw, Ringnet communications status, and so on. You can also use the HHT to emulate an
RKD node in order to program the system – via either the infrared link or over a direct connect link to the controller
serial port.
The HHT filesaver (or Panel Data Buffer) facility allows you to transfer a complete system configuration to or from a
panel or PC.
