The SX80 doesn't provide power to any external perpherials, such as the Precision 60 camera, as it requires an external power supply, this can be seen in the SX80 Install Guide.
I think you should have received a power supply with the P60 camera, but I think the part number is PSU-12VDC-40W2.
What is the part numberfor Power Cube for P60 Camera, as It will not power up if I only connect it to SX80 Codec LAN port ?
