I have a dbox2 Nokia 2x for cable and I put a HD (3.5â€) with the Hallenberg kit. When I installed the kit and the HD, I had a lot of problems and I needed to put a fan to solve this.
I see the electrical diagram to start on the fan only when the dbox2 are ON.

When reboot the dbox2, the HD start, and if you don et use in a few minutes the HD stop. I need start the fan only when the HD are runing, because in the other cases I don’t need the fan. To make it, I need change the “CS34†conection point for other.
Where can I connect it , to know when the HD is running?
If it’s imposible, other solution is, create a new electrical diagram with a timer (555) and conect it to the HD led. Where can I connect the HD led?
Other solution is modify the “recording.start†script and start the dbox2 before to start record.(This is necessary because it’s possible record when the dbox2 show the hour)
Thank you
