Configuring Intercoms
Configure Intercoms
When Intercoms are shipped from Aiphone, they do not have IP address information
configured. To configure them, you must connect them to your network, install TalkMaster™
and select the menu Admin Configure Intercoms.
The Intercom Configuration Tool will immediately search for all Aiphone intercoms connected
to your current network segment. You must match the loom ID displayed on the TalkMaster
screen to the ID# printed on the back of the intercom and then configure the Intercom's IP
address information and the IP address of the server it will connect to.
If you have intercoms located in a different network segment, you may not find them since
many routers filter out UDP Broadcasts. You can either install these intercoms on the current
network segment or you can install a copy of TalkMaster in the other network segment to
configure your intercoms. You may also refer to the TalkMaster installation CD for instructions
on installing the UBAM™ software which will allow you to configure units across different
networks.
A network segment is determined by looking at the subnet mask and the corresponding bits in
thelP Address. For example, on IP Address 192.168.2.175 Subnet 255.255.255.0, the
network segment is 192.168.2, and on IP Address 126.10.11.12 Subnet 255.255.0.0, the
network segment is 126.10.
To configure Intercoms to connect to TalkMaster™, see Intercom Configuration - TalkMaster
Clients.
To configure two Intercoms to communicate with each other in Direct Mode, see Intercom
Configuration - Direct Mode.
Advanced Configuration
When the Advanced Configuration option is checked in the Intercom Configuration Tool View
Menu, you can specify addition options for an IP Intercom.
If these options are grayed out, you have an intercom with legacy firmware. You can configure
intercoms with legacy firmware from the main TalkMaster™ screen using the menu Admin
Preferences and selecting the Legacy tab. To update the firmware, see Updating Firmware.
Fail Forward IP 1,2,3 allow you to specify up to three IP addresses of alternate TalkMaster
consoles that this Intercom will attempt to connect to if it's current TalkMaster console
becomes unavailable. If an Intercom has failed forward to an alternate IP and it's default
TalkMaster console is restarted, the default TalkMaster console can reacquire the intercom by
using the menu Console -> Retrieve Intercoms.
GPIO 4 Control Mode allows you to specify how General Purpose I/O (GPIO) port 4 is used.
On Intercom models IP-EWST and IP-EWST-POE, GPIO 4 is connected to a relay (dry
contact).
The normal state for GPIO 4 is logic high (+5 volts). When activated, it changes to logic low (0
Volts).
