Detailed Product Description

AN-PH-RS-232/422/485 is RS-232 to RS-422/485 Photoelectric Isolation Interface Converter. It's compatible with RS-232C, RS-422, RS-485 standards, and capable of converterting single end RS-232 signal into RS-422 or RS-485 balanced signal.

AN-PH-RS-232/422/485 IsolationInterface Converter is compatible with RS-232C, RS-422, RS-485standards and capable of converting single end RS-232 signal intoRS-422 or RS-485 signal of balanced signal.

     The built inphotoelectric isolator can offer 3500V isolation voltage and the rapidTransient Voltage Suppressor (TVS) can effectively inhibit lightningand ESD, prevent lightning strike and common code interference. ConnectPC, IPC, or portable computer via a DB9 female connector at RS-232interface, and connect RS-422, RS-485 end via convenient 4-bitterminal. The RS-485 supports dual-line half duplex, namely, the onlytwo lines of RS-485 shall both send and receive data. Handshake signal(e.g. RTS, Request To Send) usually controls the data direction.

    The inner circuit of AN-PH-RS-232/422/485 PhotoelectricIsolation Interface Converter can detect data direction and switch tocontrol it automatically, conveniently to form a RS-485 network withoutany shake hand signal. This kind of RS-485 control is fully transparentand need no software amendment for the former working modes basing onRS-232.

   Photoelectric Isolation Interface Converter canprovide credible connection for point to point, point to multi-pointcommunication. The point to multi-point allows connecting 32 RS-422 orRS-485 interface devices with data transmission speed of 0-115.2KBPS.The dual color data flow indication light can indicate malfunction. Itsupports communication modes including RS-232C to RS-422, RS-232 toRS-485 conversion.
