Keyboard connections

The keyboard input and output connectors are used to connect a Bosch Intuikey keyboard to one or more 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 unit. Up to 16 Divar 700 units can be connected and controlled in this manner with one keyboard. Additionally up to 10 Divar 2 recorder units can be operated with the same keyboard.

The following accessories are available:

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 supply for the external keyboard. The recommended cable type is Belden 8760 or equivalent.

By using a keyboard Port Expander unit (LTC 2604) up to 4 Intuikey keyboards can operate recorder units.

With the Video Manager (LTC 2605), up tp 16 Divar recorders and up to 6 monitors can be operated from 1 to 4 separate Intuikey keyboards.

Termination

Connect the keyboard terminator (supplied with the Intuikey keyboard) to the KBD out connector. If multiple units are controlled with a single keyboard, the KBD out connector of the last unit must be terminated.
