Part number: ATC-107N
In Stock : Available
Driver & software

product overview

    ATC-107N Isolation Interface Converter is compatible with RS-232C, RS-422, RS-485 standards and capable of converting single end RS-232 signal into RS-422 or RS-485 signal of balanced signal. The built in photoelectric isolator can offer 3500V isolation voltage and the rapid Transient Voltage Suppressor (TVS) can effectively inhibit lightning and ESD, prevent lightning strike and common code interference.

    Connect PC, IPC, or portable computer via a DB9 female connector at RS-232 interface, and connect RS-422, RS-485 end via convenient 4-bit terminal. The RS-485 supports dual-line half duplex. The inner circuit of ATC-105 Photoelectric Isolation Interface Converter can detect data direction and switch to control it automatically, conveniently to form a RS-485 network without any shake hand signal. This kind of RS-485 control is fully transparent and need no software amendment for the former working modes basing on RS-232.

    ATC-107N Photoelectric Isolation Interface Converter can provide credible connection for point to point, point to multi-point communication. The point to multi-point allows connecting 256 RS-422 or RS-485 interface devices with data transmission speed of 0-115.2KBPS. The 3 power supply and data flow indication light can indicate malfunction. It supports communication modes including RS-232C to RS-422, RS-232 to RS-485 conversion.
