Doors.NET v4.8.0 was the last software revision that will support modem communication for PXL and Entraguard products.

Modem communication for PXL and Entraguard units IS NOT SUPPORTED beginning with Doors.NET v4.9.0. 

Installers are notified of this change when selecting an Upgrade Installation in the Doors.NET installation program. Systems that have existing modem communication with controllers can continue to use modem communication using the existing configuration information. The Advanced View option will continue to display this information. Any new controllers added to an existing system must be added using either a serial connection or a LAN network connection. Should someone attempt to select modem communications a popup message box appears stating modem communication is no longer supported. Further, should someone change an existing communication path from modem to serial or network that change is made permanent and there is no reverting to modem communication.

This change was made due to the rapid conversion by telecommunication providers from POTS lines, which are completely modem compatible, to VOIP lines, which do not transfer data packets reliably and have differences that vary from vendor to vendor, making it impossible for us to ensure modem compatibility with all VOIP vendors and the VOIP hardware they use.

For Data Communication with Either PXL or Entraguard Units

• Keri recommends replacing your modems with a LAN-520 Ethernet module.
• Alternatively, if your computer has a serial communication port, you can use a direct-connection cable.

For Voice Communication with Entraguard Units

• You will need a VOIP converter for voice calling between Entraguard units and tenants.
• Keri recommends the Cisco SPA 112 VOIP Adapter, however your ISP likely has their preferred unit.
