Power standards
A number of different power supplies are used around the station.
XLR-4 (4-core)
In February 2014, the umbilical power cables were replaced with 4-core cable. This was to allow both 12V and 8.7V on the same cable but different pins, avoiding the possibility of the wrong voltage being connected
Pin-out
- 1 = Ground (yellow/green)
- 2 = 5V (brown)
- 3 = 8.7V (black)
- 4 = 12V (grey)
Standardised devices
- Sony HVR-HD1000E (HD cameras) - 8.7V
- Sony DSR-PD150 (Ex-BBC cameras) - 8.7V
- Panasonic AG-AC90 - 12V (Currently issues with distance)
- Vestel monitors - 5V and 12V
- Blackmagic Battery Converters - 12V
- Analogue to SDI converters - 5V
- Pretty much anything with 12V

These standards were once in service, but have since been removed or superseded.
