Cable Guide: DIY & Pinouts
DIY & buy guide for cables
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Cable Guide is the field reference for anyone who terminates, repairs, or buys cables for a living — or just wants to do it right at home.
It covers 65 cable types across 10 categories: Ethernet, telephone, coaxial, fiber optic, USB, display, audio, serial / industrial, power, and structured cabling.
For each cable you get:
• Step-by-step how-to instructions — strip, prep, terminate, test
• Pinouts with TRUE colors — T568A, T568B, crossover, rollover, RJ11, XLR, DB9, OBD-II, DMX-512, and more
• SwiftUI diagrams of plug bodies, fiber jackets, and coax cross-sections in real-world colors
• A list of every tool needed, with what it actually does
• Specifications — bandwidth, max length, connector type, impedance, polarity
• "Watch out for" warnings drawn from real-world mistakes (mixed 50/75 Ω BNCs, APC ↔ UPC fiber damage, 13 mm untwist rule, etc.)
• "Where to buy" — vendor search shortcuts to Amazon, Monoprice, Home Depot, Newegg, Markertek, B&H Photo, Sweetwater, Digi-Key, Mouser, FS.com, ShowMeCables, trueCABLE, and Ubiquiti Store, so you can compare prices in three taps
• "Photos" — opens a Google Images search for the exact productWhat's covered
