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.

Provides Power
GPIO Breakout
EF/RF Lens Support
HE PWR 24W Yes No No
HE PWR BREAK Yes Yes No
HE PWR & EF/RF BREAK Yes Yes Yes
HE PoE EF/RF BREAK Yes (via PoE) Yes Yes
HE GPIO BREAK No Yes No
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. See also : Camera GPIO Ports and Schematics
HE PWR 24W: Standard Power Supply Provides regulated 12 VDC / 24 W to HE cameras through an M8 connector. No GPIO signals are exposed.
