Traps
Whenever a status value changes a trap will be sent to the SNMP manager. By
interrogating this trap it is possible to identify the status change and its
consequences. It will be quite common for multiple traps to be sent for any one
incident – for example, removing an input may typically trigger eight traps. It will
then be down to the SNMP manager to sort these into a hierarchical order or mask
as necessary.

Downloading licences
The Indigo DTSE is pre-installed with an SNMP manager which will require a
licence to be downloaded and installed. The licence is available by email from
Crystal Vision’s customer support. To obtain a licence the frame’s MAC address will
be required.
Once you have obtained the licence, the file is downloaded to the frame using the
board update tool.
Click the “Refresh list” button and wait whilst the network is scanned. Once done
then select the frame for upgrading from the “Board to talk to” drop-down list by IP
address or name.
Select the “Download license file” tab and click on the Browse button. Navigate to
the folder containing the Licence file. Click “Download to Board” and wait.
It will now be necessary to reboot the frame. This can be achieved by cycling the
mains supply to the frame or, if not convenient, carefully removing the ribbon-cable
connector from the front panel PCB.
