Features:
- Full-duplex optical link: Transfers transmit and receive data simultaneously without a copper communication cable.
- 100 m operating range: Supports defined serial communication across moving or separated equipment.
- Industrial serial interface: Connects through RS-422 and a D-sub 25-pin port.
The optical path and the wired RS-422 interface must both be correct for a working link.
Separate carrier frequencies allow simultaneous transmit and receive operation between the paired units.
Commissioning should include real data in both directions under the intended motion and lighting conditions.
Apter Power supports HOKUYO EWF-11A-D quotations, technical documents, and optical-link application review.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- RS-422 interface: Confirm differential pair assignments, signal reference, and D-sub pinout.
- Full-duplex path: Test both transmit and receive directions independently.
- Serial settings: Set both endpoints to the same baud rate, data format, and host timing.
- Cable control: Use suitable shield, grounding, and strain relief on the electrical side.
- Power check: Measure 24 VDC at the unit while the link is operating.
- Optical path: Remove obstructions and confirm the paired units face the correct direction.
- Window condition: Clean contamination with a compatible method that does not scratch the cover.
- Fault isolation: Separate host wiring, optical alignment, and remote-unit checks before replacing hardware.
- Temperature: Keep operation within -10 to +50°C.
- Humidity: Avoid condensation while remaining at or below 85% RH.
- Ingress protection: Install the IP40 housing inside an appropriate protected environment.
- Vibration and shock: Mount securely within the documented mechanical limits.
- Moving-machine communication: Transfers serial data where a trailing communication cable is undesirable.
- Overhead handling: Links fixed and travelling equipment across a clear optical path.
- Rotating or indexed stations: Carries RS-422 data between aligned positions under controlled geometry.
- Legacy optical links: Maintains an installed EWF-11A serial communication arrangement.
