Archos AV500 and AV700 video accessory pinout assignments and voltage regulation modifications
20 years old. Gear and prices may have changed since.
What the thread found
- The Archos video pod connector uses purple for +5 volts center of DC coax, grey for power ground and coax shield, dark green for video in, yellow for video out, brown for left audio out, red for right audio in, orange for left audio in, and black wires for grounds
- A switching 5 volt 2 amp voltage regulator can replace the internal 7808 regulator in the PRO series battery cage to improve power stability
- A video distribution amplifier accepting 8-36 volts input can be installed in the PRO lower j-box to isolate and condition three separate video feeds with gain control and DC restoration
- Video signal noise on external monitors can be minimized by isolating the video feeds using a distribution amplifier with separate outputs for recorder, monitor, and transmitter
- Crazy glue or 3M epoxy are better attachment methods than hot glue for internal components as they do not insulate the voltage regulator heatsink
Depends on
- Pinout details apply specifically to Archos AV500 and AV700 models
- The voltage regulator modification and distribution amplifier installation are described for PRO series equipment
- The distribution amplifier modification requires soldering skills and component sourcing from specific vendors
- Some participants mentioned alternative regulators and techniques without complete specifications
