IPI 100 Series Installation Instructions

IPI 100 Series Overview

The Extron IPI 100 series are one- (IPI 101) or four- (IPI 104) button IP intercom modules that are used to create an easy-to-use, two-way IP Intercom® system. They facilitate room-to-help-desk or room-to-room communication within a building, campus, or a wider area, as long as the intercoms are connected to the same network. The IPI 101 can communicate with one other location; the IPI 104 can communicate

with four other locations.

Each room in the Intercom system requires either an IPI 100 series, with an

MLC 226 IP MediaLink® Controller or an IPI 200 series module. The IPI 100 module must be connected to the the

MLC 226 IP controller. The IPI 100 must be no more than 100 feet (30 meters) from the controller; a 12 inch (30.5 cm) cable is provided. Only one IP address and network drop are needed because the IPI 100 uses the same network drop as the MLC 226 IP Controller. Consult with your IT department to ensure that IP addresses have been correctly allocated.

Also on the network, there must be at least one PC that is running the IP Intercom HelpDesk™ software to coordinate the intercom system. The IP Intercom HelpDesk software, which is provided with the IPI 100 Series intercoms, allows any PC on the network equipped with a microphone and speaker, or a headset, to become a help desk station. The software is also available for free download from the Extron website (www.extron.com).

The IP Intercom HelpDesk software offers the following features:

•Works with IPI 100 Series IP Intercom stations to enable two-way communication with a classroom and ensure rapid problem resolution.

•Sets up, accesses, and manages audio for IP Intercom modules.

•Pages one room or a group of rooms.

•Forwards calls automatically from a help desk that is busy to one that is available.

Network and IT administrators should use information from the following white papers, which can be found on the Extron website (www.extron.com), to ensure optimal network configuration and compatibility for the IP Intercom system:

•“IP Intercom Network Impact Statement”

•“IP Intercom Best Installation Practices”

Extron recommends that the IP Intercoms and the HelpDesk be on the same LAN with a static IP address and not be separated by a firewall. If the IP addresses are on different subnets, it is best to set up a dedicated VLAN. If a firewall is required,

the following ports need to be open: UDP port 3121 (audio traffic), TCP telnet port 23 (control and status), UDP port 3122 (inter‑helpdesk communication), and UDP ports 1230 and 1231 (auto discovery).
