Some Basic Information about STS standards of 4U Serge: (C&P from ModWiggler Forum)
Banana Jack Color Code
Black = AC-coupled (IN or OUT)
Blue = DC-coupled (IN or OUT)
Yellow = Trigger (IN)
Red = Gate (IN or OUT)
Grey = White Noise (OUT)
Purple = Pink Noise (OUT) or Sync (IN)
PSD vs Obelisk
the psd (power supply distribution) is for shop panels while the Obelisk is for m-odules. The obelisk contains a PSD like distribution board - but with only 4 connectors instead of 5.
Power Connector
The standard inter-connector used by STS is a Tyco Rectangular 4 pin Connector. The body and pins are sold separately.
Pin & Socket Connectors PLUG W/O EAR 4P inline is PN: 770078-1
Pin & Socket Connectors 24/18 AWG TN/BR SKT is PN: 770146-1
Pin & Socket Connectors RECPT 4P DETENT LOCK in-line is PN: 770075-1
Pin & Socket Connectors 24/18 AWG TIN/BRASS is PN: 770147-1
The PSD has the female connectors.
Pin 1 is at the point. Pin 4 is at the flat (for both male and female).
Pin 1 = Ground 1, Black
Pin 2 = -12V, White
Pin 3 = Ground 2, Green
Pin 4 = +12V, Red
STS also uses a 5 pin XLR connector for power distribution. Coming from the power supply (PS4 for example) is a 5 pin female XLR. It is intended to be plugged into a panel mount 5 pin male XLR connector which then terminates to a male Tyco Connector (for plugging in power to the PSD). I used an Aphenol panel mount 5 pin male XLR connector, PN: AC5MDZ for a replacement part and it worked fine.
Here is what my PS4 XLR connector pinout is (note, I am not sure if this is standard or not, i would assume it is, but I dont want to be responsible for plugging anything in backwards):
Pin 1 = +12V, Red
Pin 2 = Ground 1, black
Pin 3 = -12V, White
Pin 4 = Ground 2, green
Pin 5 = Not Connected
PS2a Specs
the PS2a is a line lump, laptop type power supply. It is manufactured by Jerome Industries (Elizabeth, NJ). Their part number appears to be MIKS20-14 and has "Serge Power Supply" written on it. It appears to be a switching type power supply and can be switched from 115VAC to 230VAC inputs
12V @ 350mA
-12V @ 350mA
Fuse Type (T). 250mA, 250V.
PS4 Specs
Inside of a custom case (LMB boxes LINK maybe?) is a condor linear power supply model HAA15-0.8-A+
Technical/Catalog Information for the HAA15-0.8-A+
Vendor - SL Power Electronics Manufacture of Condor/Ault Brands

Voltage Input - 100, 120, 220, 240VAC
Power Supply Type - Linear, Regulated (Open Frame)
1st Output - +15 VDC @ 800mA (This number should be a bit higher at 12V)
2nd Output - -15 VDC @ 800mA (This number should be a bit higher at 12V)
Mounting Type - Chassis Mount
Size / Dimension - 6.5" L x 4" W x 1.62" H (165.1mm x 101.6mm x 41.2mm)

It is wired to an on/off switch and on LED indicator (wired to the -15V rail). The output is a 5 pin XLR with the following pinout: (coming soon).
