The ATEN IC485S is an outstanding two - way interface converter designed for long - distance applications. It efficiently converts RS - 232 signals to and from RS - 422/RS - 485 signals over distances up to 1200 m (4000 ft.). This converter supports the connection of up to 32 hubs and comes with a monitoring feature to confirm data passing between devices. Key features include data transmission controlled by the RTS signal, selectable DCE/DTE mode, multiple link selection options like point - to - point, multidrop, and simplex/duplex. It offers four - wire full - duplex and two - wire half - duplex communication. With a compact size, it can reach a cable distance of up to 1200m (4000 ft.). It supports monitor configuration and baud rates up to 115.2Kbps, and is compatible with Windows 2000 and Windows XP. Technical specs show it has a DB - 25 female RS - 232 connector, an RS - 485/RS - 422 four - terminal block, and an RJ - 11 female connector. It has various switches for different settings, low power consumption, and wide environmental tolerance.

Using the ATEN IC485S is quite straightforward. First, connect the DB - 25 female connector to your RS - 232 device. Then, connect the RS - 485/RS - 422 four - terminal block or the RJ - 11 female connector to the appropriate device on the other end. You can use the switches to set the mode according to your needs, like DCE or DTE. When it comes to data transmission, make sure the RTS signal is properly configured. For long - distance applications, remember it can reach up to 1200m, but the data rate might be up to 100 Kbps under this distance. Keep the device in an environment where the temperature is between 0 and 50 degrees Celsius and the humidity is between 0 and 80% non - condensing. For storage, the temperature can range from - 20 to 60 degrees Celsius. The plastic housing is durable, but try to avoid dropping or hitting the device. Clean it with a soft, dry cloth regularly. If you have a rack - mount product, note that the standard physical dimensions are expressed in LxWxH format.
