HE (Eros) Power Accessories

This document from Emergent Vision Technologies describes HE (Eros) camera power accessories, including regulated 12 VDC power supplies and GPIO breakout cables. These accessories work with HE high-speed cameras, provide reliable power delivery, and offer convenient access to GPIO signals. Selected models also expose control lines for EF/RF lens adapters (EF = Canon EF mount, RF = Canon RF mount).

The sections below summarize the accessories, list technical specifications, and provide pinout tables to support system integration.

Feature Matrix

Accessory Provides Power GPIO Breakout EF/RF Lens Support
HE PWR 24WYesNoNo
HE PWR BREAKYesYesNo
HE PWR & EF/RF BREAKYesYesYes
HE PoE EF/RF BREAKYes (via PoE)YesYes
HE GPIO BREAKNoYesNo

Notes

  • All GPIO breakouts use flying-lead wires.
  • Flying-lead length: 200 mm.
  • PoE accessories do not contain a power supply; the camera receives power over Ethernet from the PoE network equipment.
