FIX: Zetafax Server gives error on startup when configured with Brooktrout Analog devices



ID: ZTN1818

This Zetafax technical note applies to:

  • Zetafax 2010


When adding or modifying a Brooktrout Analog device (using the BTA driver) and starting the Zetafax Server, the device is not initialized and the following error occurs:

  • SYSMAN - (E) - DeviceGroup detected with less than 1 individual device


This was due to a problem in the Zetafax Configuration program that caused the number of channels on the device to be reported incorrectly to the Zetafax Server.


An update is available from Equisys Technical Support.


This issue was corrected in Zetafax 2011.
