CGS91 About

PCB Mounting Rail for Serge style panels.

Gate Sequencer

Hole positions for the CGS91.
The ends both have two holes.
It is likely the upper hole will be used for both mounting AND holding a PCB.
If mounting directly to the front panel then you may need to choose holes further along the strip
to avoid panel mounted pots.
Of course, two boards are required per boat, one as the upper mounting rail, and one as the lower.

Pad identification:

O1 to O10	Outputs
0V	0V power rail
+VE	positive voltage power rail. usually +12V
+V2	unspecified voltage power rail such as 6V or 5V. We recommend using this as a 2nd 0V
-VE	negative voltage power rail. Usually -12V

Construction

Short spacers (or a couple of nuts) are needed to space the module boards off the rails so that there is space for the power wire, and so the PCB tracks on the modules are not shorted. 12mm M3 bolts with 5mm spacers is the recommended combination.

If using the CGS91 mounted directly to the front panel then the end mounting bolts and spacers need to be long enough to clear your panel mounted components - 16mm bolts with 10mm spacers is the minimum recommended combination.

The CGS91 is also suitable for mounting in to the base of the boat and is the recommended approach

Suggested method for wiring modules to the integral power bus.

Each module on the panel is connected like this. The other ends of these wires to the rear of a module's onboard power connector. Power can now be fed to the whole panel through that board's power connector. Power connectors could be omitted from all but one PCB on the panel, although if installed, they are convenient for initial testing of the boards off-panel!
