Minimum MLC 226 IP MediaLink Controller hardware required – Applies to the IPI 101 AAP, IPI 104 AAP and MLC 226 IP Series only:

The IP Intercom HelpDesk software will work properly only with MLC 226 IP MediaLink Controllers shipped after November 16, 2005 with ER E16076 or later. Controllers that support the IP Intercom HelpDesk software feature a second RJ-45 connector labeled “Intercom” and an audio output.

Minimum MLC 226 IP MediaLink Controller Firmware required – Applies to the IPI 101 AAP, IPI 104 AAP and MLC 226 IP Series only:

The IP Intercom HelpDesk software will only work properly with MLC 226 IP MediaLink Controller firmware version 1.05 or greater.

Minimum Microsoft .NET Framework and DirectX versions required:

Microsoft .NET Framework version 2.0 and DirectX 9.0c or greater are required

to be installed on the help desk computer running Windows XP before running the IP Intercom HelpDesk software. Microsoft .NET Framework version 3.5 and DirectX

IP Intercom HelpDesk software TCP/IP protocols and standards – The

following ports should be open for the IP Intercom system to work properly:

 TCP Port 23 – Telnet protocol for control and status

 TCP Port 3122 – Inter helpdesk communications

 UDP Port 3121 – UDP (User Datagram Protocol) for sending audio traffic

 UDP Port 1230 and Port 1231 – UDP for the auto discovery function

TECH NOTES - Continued

Do not run the IP Intercom HelpDesk software and IP Link Device Manager simultaneously:

Both applications use port 1230 to scan the local subnet for devices. Only one application can use port 1230 at a time.

Intercom modules must be configured to call the help desk – If an intercom

module is not set up to call a help desk on one of its call buttons, it will be unable to receive communications from the help desk even though the module is shown in the HelpDesk software’s inventory of intercom modules. In addition, the HelpDesk software’s main screen will only show status (Active/Inactive) information.

panel mode will only work in the same network subnet –

Panel-to-panel mode will only work when both Panel-to-panels reside on the same network subnet.

Virtual machine – Extron does not recommend running IP Intercom HelpDesk

software under Virtual Machine such as VMWare which creates a virtual operating system session on a PC. A dedicated PC running Windows XP or Windows 7 should be used as help desk.

Dynamic plug / unplug PC’s microphone & speaker devices – The IP Intercom

HelpDesk software may not work properly with dynamic plugging in and unplugging PC’s microphone and speaker devices with help desk PC running Windows 7. PC’s microphone and speakers must be plugged in all the time with help desk PC running Windows 7.

Remote Desktop – Prior to “remote in” to launch the IP Intercom HelpDesk

software from another PC, it is recommended that the “Remote audio playback” option under the “Local Resources” tab in Remote Desktop Connection is set to “Play on remote computer”.

Microsoft Windows 2000 is no longer supported – The IP Intercom HelpDesk
