Actor
Forum 523/524 can be connected to a door intercom system of the “Door-
phone”. This intercom system is connected to one of Forum 523/524’s a/b
ports via the “Doorphone” module (see
Intercom System (for a/b) starting on
page 53).
The actor port also makes it possible to connect a separate door-opener. To do
this you will need a twin-wire connection cable.
LAN Ports
The LAN ports (LAN1, LAN2 and LAN3) support 10 MBit/s and 100 MBit/s
transfer rates in half duplex or full duplex operating mode. You can integrate
Forum 523/524 into your company’s network (LAN, Local Area Network) via
the LAN ports (Ethernet ports, here provided as RJ45 sockets). This enables
you to use Forum 523/524 for VoIP telephony, to operate the Web console or
to use the Forum 523/524 as an IP router for connection to the Internet,
among other things.
Transfer rates and operating modes are switched automatically (“Auto-
Sensing function”). Connections requiring a crossover Ethernet connection
cable are also automatically switched. You can therefore also use an
uncrossed Ethernet connection cable to connect to a hub or switch. For VoIP
application, a switch device is required.
An Ethernet connection cable (twisted pair cable in accordance with 10BaseT
or 100BaseTX) may be up to 100 m long. Safe operation with 100 MBit/s
transfers requires the use of category 5 cables and connecting sockets. Use a
shielded Ethernet cable (STP cable, Shielded Twisted Pair cable).
There is an internal Ethernet switch with several ports on the Forum 523/
524’s main board. The switch is connected to LAN1, LAN2, LAN3 and slot 2.
The CPU provides two separate Ethernet interfaces/ports internally. One of
these interfaces/ports is connected to the LAN ports, the other to the WAN
port.
