OpenCom 150: V.24 and doorstation equipment slots
The OpenCom 100 has two slots in which special interface cards can be operated
(V.24 and doorstation equipment). You can see the location of these slots in the dia-
grams.
• The doorstation equipment interface card (also called "Door Phone" or "Door Bell")
provides "actor" ports and "sensor" ports.
With the OpenCom 130 and the OpenCom 131 systems, an "M100-TFE" interface
card can be used. For connecting a door station, this card type offers two actor and
three sensor ports.
With the OpenCom 150 system, an "M100-TFE-2" interface card can be used. This
card type offers four actor and four sensor ports. With this card, two door stations
can be connected with two call buttons for each door station.
• The V.24 interface card provides a serial port.
Proceed as described below to install one or both of these interface cards:
1. Turn off the OpenCom 100. Open the housing cover.
2. Remove the slot card from the transport packaging. Check that it is the correct
type of slot card. (There is a sticker with the type name on the connector.)
