The Hokuyo DMS‑HB1‑Z40, DMS‑GB1‑Z28, DMS‑HB1‑Z09, DMS‑GB1‑Z35, and DMS‑HB1‑Z52 are 8‑bit parallel optical data transmission devices designed for reliable short‑range wireless communication in industrial automation applications such as AGV/AMR docking, conveyor handoff, and material handling interfaces. These devices transmit and receive 8‑bit parallel input/output signals wirelessly using infrared light and pulse modulation, eliminating the need for physical cables and offering robust performance in environments with ambient light up to 4000 lux. Each model provides half‑duplex two‑way transmission, parity check error verification, and a D‑sub 25‑pin connector interface for easy integration with PLCs and controllers. Variants differ mainly in optical axis alignment (head‑on or side‑on) and optical interference handling enhancements.
