This bi-directional RS232 to RS485 converter is a port-powered simple and reliable solution for most standard commercial and industrial communications needs. It converts RS232 signals to half-duplex RS485 balanced differential signals and can extend the communication distance up to 4000 FT (1.2 km).
This RS232 to RS485 converter is port-powered, it uses an internal amplifier to gain power from the RS232 signals (RTS, DTR, TXD) without interfering with the RS232 interface. In case the RS232 port is not capable of supplying sufficient power an external power supply can easily be connected to the converter.
Automatic Send Data Control is enabled which means no software drivers are needed.
This converter utilizes the solid MAX485E processor chip from Maxim/Dallas Semiconductor and a supporting driver IC from Philips, which makes this RS232 to RS485 converter suitable for most applications, including industrial, business and any general office computer device.
It is a bi-directional RS232 to RS485 converter (meaning it communicates in both directions), reliable and cost-effective that easily lets you connect any RS485 device directly to your computer's serial RS232 COM port, efficiently converting standard RS232 signals to RS485 and vice versa.
A simple and reliable solution for most general and industrial communication needs. Header terminal board is included with each converter.
