EDT, Inc.
Power Connector
Below are the pin assignments for the power connector – either a standard coaxial Switchcraft or an optional Lemo.
Figure 5. Pin assignments – standard Switchcraft or optional Lemo connector
With the Lemo, you can use various cables that allow auxiliary signals.
Cable Assembly – Lemo to Loose Wire
The Lemo to loose wire cable assembly (EDT part #016-12650) can be wired as needed or connected to various types
of connectors, depending on your application.
Cable Assembly – Lemo to Male DB9
The Lemo to male DB9 cable assembly (EDT part #016-12718) supports signals that can be used as an auxiliary
signaling system for a variety of purposes.
For example, with custom firmware you could control the camera’s pan and servo motors, or set up a hardware trigger
that is local to either end. If you wish to explore these options, contact EDT.
Unlike the DB9 in the female assembly, this DB9 has no looped-back signals or integrated level conversion.

Pin 1 is power
to the extender
(+12 V DC).
Key in connector barrel (at top).
Pin 2 is power to the extender (+12 V DC).
Pin 7 is ground (for signals and power).
Pins 1, 3, 4, 5, 6 (defined by firmware used in extender)
typically are used at CMOS +3.3 V signal levels, though
pins 1,6 and 3,4 can be configured as LVDS pairs.

All five CMOS 3.3 V signals go to
FPGA I/O 3.3V pins using series
100-ohm resistors.
Custom firmware can be used to
configure these pins as input or
output.
