American Dynamics ad1676b Manuel De Montage
KEYBOARD CONNECTIONS
The 1676 keyboard is supplied with a wall-mount transformer
(7.5 VAC), part number TP8059, a seven-foot 8-pin modular
cable, part number JJ0007, and an 8-pin modular junction box,
part number HP0047. The 8-pin modular format is commonly
referred to as a RJ-45.

Junction Box Mounting
The HP0047 Junction Box (Figure 2) interfaces with three
separate components: the 1676 keyboard, the wall-mount
transformer, and a Matrix Switching System (i.e., 1650B, 1996
CPU, 2150, 2350).
separate components: the 1676 keyboard, the wall-mount
transformer, and a Matrix Switching System (i.e., 1650B, 1996
CPU, 2150, 2350).
The junction box is connected to the 1676 keyboard with the
supplied modular cable. The wall-mount transformer is
connected to the junction box with a 2-wire cable. The
junction box must be located within reach of both the modular
cable and the cable from the wall-mount transformer. The
junction box is connected to a Matrix Switching System with
either another junction box (supplied with that switching
system) or via a 1981 Port Expander, using 9-pin connectors.

DO NOT INSERT THE WALL TRANSFORMER INTO
THE POWER SOURCE UNTIL ALL CONNECTIONS
HAVE BEEN VERIFIED.
Junction Box Connections
To connect the junction box to the keyboard, plug the modular
cable into the 8-pin modular jack both in the junction box and
on the bottom of the keyboard (Figure 3, page 3).
