WR-1021-VD 1 VGA 1 in 2 out distributor is a long distance output product for VGA signals, supporting one short-distance VGA output and one CAT5 RJ45 network cable long-distance output. It uses 4 pairs of UTP CAT5 twisted-pair cables for long-distance transmission, replacing the original VGA transmission. CAT5(STP CAT 5) network cable effective distance can reach 300 meters.
This manual describes the WR-1021-VD VGA 1‑in‑2‑out distribution unit. It supports a short‑range VGA output together with a long‑range CAT5 RJ45 output, allowing video transmission up to 300 m. The device is compatible with LCD projectors, monitors, and other VGA‑based displays commonly used in schools, museums, and AV systems.
Installation notes cover cable selection, skew mitigation, and power connections. The unit requires a 5 V DC supply (500 mA) and includes dimensions, operating temperature, and humidity limits for proper integration into AV installations. This manual is written in Japanese.
