Pinouts
Connector pinouts & wiring diagrams
Pin assignments for the connectors live production runs on: XLR, DMX, speakON, powerCON, RJ45/etherCON, and more. Every page has a face-view diagram, a pin table, and the termination notes that keep a midnight re-solder from becoming a polarity hunt.

Video & LEDDB9 RS-422 Pinout
DB9 RS-422 pinout for Sony 9-pin (P2) machine control: transmit and receive pairs, grounds, and controller vs device direction, as used for deck and server control.
Power & ElectricalpowerCON Pinout & Types
powerCON pinout: line, neutral, and earth terminals; blue power-in vs grey power-out; and TRUE1 vs original powerCON breaking capacity and outdoor ratings.
LightingSocapex 19-Pin Pinout
Socapex 19-pin pinout: six circuits with hots on odd pins 1-11, neutrals on even pins 2-12, grounds on 13-18, pin 19 unused. Break-in/break-out usage notes.
AudioXLR 4-Pin Intercom Pinout
The 4-pin XLR intercom headset pinout: mic on pins 1 and 2, earphone on pins 3 and 4 in the Clear-Com convention, with notes on brands that wire differently.
AudioTA4 Mini-XLR Pinout
TA4F (TQG) mini-XLR pinout for Shure beltpacks: pin 1 shield, pin 2 bias, pin 3 audio, pin 4 bias return. Wiring notes for lavs and instrument cables.
Video & LEDHDMI Pinout
HDMI type A pinout: all 19 pins, from the three TMDS data pairs and clock to DDC, CEC, ARC/HEAC, +5V, and hot plug detect, with field notes for AV work.
Power & ElectricalEdison (NEMA 5-15) Wiring
NEMA 5-15 Edison wiring: the narrow blade is hot (brass screw), the wide blade neutral (silver), the round pin ground (green). Plus the 5-20 T-blade variant.
LightingStage Pin (2P&G) Wiring
Stage pin (2P&G, Bates) wiring: ground is the center pin, longer so it makes first; hot is the outer pin farther from center, neutral the closer one.
Power & ElectricalNEMA Twist-Lock Wiring
NEMA locking connector terminal codes: G green ground, W silver neutral, X/Y/Z brass hots. Wiring tables for L5-20, L6-30, L14-30, and L21-30 on one page.
AudioAES/EBU XLR Wiring
AES/EBU (AES3) uses XLR pins 1 shield, 2 data+, 3 data−, over 110 ohm digital cable. Why mic cable fails on long AES runs, and the 75 ohm BNC variant.
AudioRCA (Phono) Wiring
RCA phono wiring: center pin carries the signal, the shell is ground/shield. Unbalanced consumer line level, plus the 75 ohm S/PDIF digital variant.
AudioTT / Bantam Patchbay Wiring
TT (bantam) patch cables wire tip hot, ring cold, sleeve ground. What half-normalled and full-normalled patchbays mean, and why studios wire them that way.
Video & LEDVGA Pinout (DE-15)
VGA DE-15 pinout: RGB on pins 1-3 with returns on 6-8, H/V sync on 13 and 14, DDC data and clock on 12 and 15, +5V on 9. The legacy connector that will not die.
Video & LEDopticalCON & LC Fiber Guide
Fiber for shows: duplex LC and opticalCON DUO carry two neutral fiber channels, jacket colors mark fiber types, and APC green never mates with UPC.
