Keyboard connections
The keyboard input and output connectors are used to connect a Bosch Intuikey keyboard to
one or more Divar XF units. For one unit, connect the keyboard to the KBD in connector. For
more units, connect a cable between the KBD out connector of the first unit and the KBD in
connector of the following Divar XF unit. Up to 16 Divar XF units can be connected and
controlled in this manner with one keyboard.
For short distances (up to 30 m), standard 6-core telecom flat cable can be used to supply
power and signal connections for the keyboard (LTC 8558/00).
For distances over 30 m between the keyboard and the DVR, the Keyboard Extension Kit
(LTC 8557) must be used. This kit provides junction boxes, cables, and the appropriate power
