The KTD-400 comes with a 6-foot cable that attaches to a modular phone box. All external
connections are made in the phone box. For the KTD-300R, connections are made to the
removable terminal strip located on the rear of the unit. Figures 4 and 5 illustrate connection
details.
The illustrations below give connection points for an RS422 input cable and an RS422
output cable. Do not confuse the two. The input is used only if other keypads, alarm chassis,
or a time date generator are located ahead of the unit that is being wired.
Wiring the KTD-400 and 300R to control a standard Digiplex system involves connecting
the RS422 input cable (if used), the RS422 output cable, and the 12VDC wall transformer
(Figures 4 & 5).
