Step‑by‑step instructions for installing the high‑end bus multimedia unit, covering hardware mounting, wiring, and testing.
This installation guide explains how to correctly install the high‑end bus multimedia unit, including the main host, front and rear displays, keyboard, antennas, SIM card, speaker and camera. It emphasizes safety checks, proper positioning, and secure fastening before powering the system.
The manual details mechanical mounting, wiring standards, connector verification, and final electrical tests such as voltage checks (8‑36 V on the 3P automotive connector, 12 V host output) and speaker impedance verification (2 Ω minimum, 4‑8 Ω recommended). Follow the procedures to ensure reliable operation on the bus. This manual is written in Chinese.
| Power cable minimum cross‑section | ≥ 1.5 mm² |
|---|---|
| Recommended speaker impedance range | 4 Ω – 8 Ω |
| 3P automotive connector voltage range | 8 V – 36 V |
| Host output voltage | 12 V |
The power cable must have a cross‑section of at least 1.5 mm².
The connector voltage should be between 8 V and 36 V.
Check mechanical installation, ensure all wiring follows the standards, measure the 3P connector voltage (8‑36 V), verify antenna connections, confirm speaker impedance, and confirm the host output voltage is 12 V.
