Adapter for extending and duplicating the I-port
1. Duplicating:
if you would like to connect two I-port extensions to one module, you can
connect a second LCN-IVH/-IV to a free I-port (red jack).
2. Extension (illustr. 3, page 3):
an LCN-IVH/-IV and a further LCN-IV is needed. The LCN-IVH/-IV is
connected to the LCN module by using the supplied flat cable. Over a four
pole, max. 50m in length, shielded cable, the LCN-IVH/-IV is joined to the
other LCN-IV - see page 3.
Note: Only a maximum of five periphery devices can be operated on one
I-port (except for the LCN-IVH/-IV)!
3. Impulse sensor (illustr. 4, page 3):
For evaluating potential free contacts, these are simply connected to the
terminals “GND” and “2” (e.g. when connecting the wind sensor
LCN-IW).

Hinweise:
!Keep distances to power supplies! The connecting cable (I-port extension) between
!an LCN-IVH/-IV to another LCN-IV´s is a signal line.
!If the LCN-IVH/-IV is being used as an impulse sensor, no other groups may be
connected to the I-port (except the impulse generator.)
!Connect NO external voltages to the LCN-IV!
!The terminal “GND” on the LCN-IV is on the N potential of the connected LCN module.
!The I-port extension should be carried out using a shielded cable. The shielding is not to
be connectedt!
!If the LCN-IV is being used as an impulse counter, the cable to the impulse contact
should be as short as possible. An extension is possible (max. 50m) when using two
LCN-IVH/-IV´s.
Guidelines to I-port connections:
The I-connecting cable to the LCN module can be extended up to a maximum of 50m with
an LCN-IV (all diverted distances added together), use ³0,8mmÆ.
The distance from the LCN-NUI to a maximum of 2 GT-key sensors, must not be longer
that 20m. Only a maximum of five I-port periphery devices may be connected.
