19.2.3 Keypad interface (X5, X6)

The external interface for connecting the keypad to other keypads or to a (remote) call station consists of a IDC connector with 16 positions (see the PCB for the pin numbering). Keypads are connected in series to a call station. This means that there is only a direct connection between the call station and the first keypad. The second keypad is connected to the first, the third to the second etc. using standard flat cables.

19.2.4 ID selector (S9)

It is possible to connect:

•Up to 16 call station keypads for pre-configured actions (LBB4432/00 or LBB4434/00) to a (remote) call station.

•Up to 15 call station keypads for pre-configured actions (LBB4432/00 or LBB4434/00) and one numeric keypad (PRS-CSNKP) to a (remote) call station.

For a correct communication between the call station and its keypads, the correct ID must be assigned to each keypad for pre-configured actions using the ID selector (see figure 19.2, no. S9 and figure 19.7).

The ID of a keypad for pre-configured actions depends on its position in the array of keypads. The first keypad for pre-configured actions has ID 0, the next 1, and so on up to F for the sixteenth keypad for pre-configured actions.
