Receiving input pin events from Mango DSP units on the standby Archiver - Security Center 5.8.2.0

To receive input pin events from Mango DSP units in Security Center when the unit is managed by two Archiver roles, the second Archiver role requires a specific configuration.

1. On the Archiver role machine, navigate to the installation directory, for example, C:\Program Files\Common Files\DVR Software x.x\Extensions\Drivers\ on 32-bit machines, and C:\Program Files (x86)\Common Files\DVR Software x.x\Extensions\Drivers\ on 64-bit machines.
   x.x refers to the Security Center version.
2. Open the Generic01DriverConfiguration.xml file in Notepad.
   Text similar to the following is displayed:

   <MangoDspDriverConfiguration>
     <HttpServerNumber>1</HttpServerNumber>
   </MangoDspDriverConfiguration>

3. Change the value of the HttpServerNumber from 1 to 2.
4. Save the file and restart the Archiver.
