3.2.1 Power
The power connector is a Switchcraft 712A 2.5mm barrel
connector wired with the tip +ve and the shield -ve. A 7-
28V DC regulated supply must be used. There is some
variation amongst connectors labelled “ 2.5mm barrel” so
it is recommended that mating connectors are purchased
from GSL.

This is a standard DE9F (TIA-574) sub-miniature
(D-sub) plug, conforming to DIN 41652 and
MIL-DTL-24308. They are very widely available,
as are suitable mating connectors.
