The DA-2000 protocol conversion equipment is designed to translate E1 signals into V.35 or RS232 asynchronous data interfaces. Safety instructions advise keeping the device away from water, avoiding cable damage, and contacting the company if the unit shows signs of malfunction.
Technical specifications cover interface rates, impedance settings, power requirements, operating temperature ranges, and physical dimensions. The manual also details front‑panel indicator meanings, switch functions, clock mode settings, and typical application scenarios. This manual is written in Chinese.
