The XS202 is a bi-directional RS232 to RS422 converter which is port-powered but with an optional external power terminal which allows you to power the converter from an external 5VDC power source in case your serial port does not provide sufficient power to the converter.
This RS232 to RS422 converter supports 4-wire balanced full duplex communication, which allows your applications to operate in full-duplex. The transmission rate of 300 - 115200bps can be applied to point-to-point and point-to-multipoint networks. It is suitable for most applications, including industrial, commercial and any general office computer device.
This converter is a bi-directional RS232 to RS422 converter, (meaning it communicates in both directions), reliable and cost-effective which easily lets you connect any RS422 device directly to your computer's serial RS232 COM port, efficiently converting standard RS232 to RS422 signals in full-duplex RS422 and vice versa, without the need for any drivers or other control software.
This particular converter utilizes the popular MAX491 processor chip from Maxim/Dallas Semiconductor and a supporting driver chip from Philips.
A simple and reliable RS232 to RS422 converter for most general and industrial communication needs.
Header terminal board is included with each converter.
