control unit and 5 in Fig 8 for the keypad).
Fitting a jumper to the pins adds a
termination to the cable.
In a daisy chain configuration terminate
each end of the chain (see Fig 11 ).
In a star configuration:
If there are only two keypads then this
is the same as a daisy chain
configuration. If required terminate at
each keypad.
If there are more than two keypads
AND two cables are long while the
remaining keypad cables are short (less
than 10m) then it is possible to
terminate at the two keypads with long
cables.
If there are more than two keypads BUT
each keypad cable is more than 10m
then DO NOT terminate.
Keypad Addressing
Each keypad connected to an end station
must have a unique address. See Figure 8
on page 4 for the position of the addressing
jumpers.
