• Wireless optical data transmission under unobstructed line of sight
• DDLS 500 supports high-speed 100 Mbit/s Ethernet transmission
• DDLS 200 supports stable data transmission for various industrial bus protocols
• Heating option for extreme low-temperature environments (-35°C for DDLS 500, -30°C for DDLS 200)
• Parallel transmission lines can be decoupled to exclude mutual crosstalk
• Remote start/stop input control (IN terminal: 0–2 V = off; 18–30 V = on)
• Three operating modes: AUT (automatic), MAN (manual debugging), ADJ (alignment)
• 10-segment LED light column displays received signal strength
• OUTTWARN alarm output for low receive strength (max 100 mA, with short circuit/surge/overheat protection)

• Conveyor Systems: Integration of transfer cars of all types into existing industrial system communication networks
• Electroplating Plants: Gantry systems where multiple hangers moving in sequence must be connected in parallel to a central master computer in confined spaces
• Automated Stereoscopic Warehouses: Fixed transmission between storage systems
• Building-to-Building Transmission: Long-distance data transmission between structures
• Rotary Transmission: Data transmission for rotating equipment
• Stationary/Moving Object Transmission: Long-distance data links for both stationary and mobile industrial objects

• Pairing: Devices must be installed in opposite directions in pairs with an unobstructed light path
• Mounting: Secure with 4 × Φ5mm screws
• Alignment: Optical opening angle of ±0.5° (DDLS 200); fine-tuning angle of ±6°
• Anti-Interference Spacing: For parallel same-frequency devices, minimum spacing is 300 mm (120 type) or 500 mm (200 type); spacing must be calculated according to distance formula for same-frequency parallel operation
• Coaxial Optical Path: Paired installation ensures coaxial optical paths
• Maintenance: Clean optical windows monthly using a soft cloth and glass cleaner; avoid solvents such as acetone
• Laser Safety: Class 1M laser product (DDLS 5xx) — never observe directly using telescope optics; invisible laser radiation at 852 nm wavelength with maximum peak output < 36 mW
• Power Interruption Effect: Power outage or obstruction of optical path is equivalent to bus disconnection
• Mode Switching: Long press >2 seconds to switch between AUT and MAN; short press to switch between MAN and ADJ (both ends must be in MAN mode for ADJ)
