HAND-HELD TERMINAL WIRING
The HHT is a very reliable unit, but the 6-conductor coiled cord or its RJ-11-6 modular
connectors can be damaged by over-stretching or being dropped. The coiled cord is wired as
a straight pin-for-pin assembly and the parts required to construct a replacement cable can be
obtained from many electronics supply companies. Although similar in appearance, the cable
set is not the same as an RJ-11-4 (4-conductor) telephone coiled cord.
Adapter Plug Wiring
Figure 3-4 shows the internal wiring of the DB-25 interface adapter plug that is used to
connect the HHT to the transceiver.

HHT ALTERNATIVES
As an alternative to using the HHT, a PC running terminal software (such as PCPLUS™,
PROCOMM™, etc.) can be used to program the transceiver. Also, any ASCII terminal
