a/b Ports

The a/b ports are for operating ana-
logue devices (a fax machine, mo-
dem or telephone). The maximum
permissible length of the cable is
1,000 m when twin-wire 0.6 mm ca-
ble (with twisted pairs) is used.
Doorstation equipment can be acti-
vated on an a/b1 port. In this case,
an electronic switch enables the
low-frequency voltage to be sepa-
rated from the feed.

Actor/Sensor

In order to operate an entrance in-
tercom and door opener, you need
four twin-wire cables:

LAN Port

The LAN port on the basic module
enables integration of the
OpenCom 130 into an existing in-
house LAN by means of a 10 Mbit
hub.
The LAN ports on the add-on mod-
ule (LAN0, LAN1 and LAN2) lead to
the Ethernet switch of the add-on
module. These LAN ports support
10 Mbit/s and 100 Mbit/s transmis-
sion speeds in half- or full-duplex
operation. The change in transmis-
sion rate and mode of operation is
automatic ("auto-sensing func-
