RS232 to RS422 adapter

$29.00 In stock

This bi-directional RS232 to RS422 adapter is port-powered with an optional external power supply terminal. An internal amplifier supplies power from the RS232 port without initializing the RS232 to RS422 interface. If the RS232 port is not capable of supplying sufficient power, an external power supply can easily be connected to the converter. This RS232 to RS422 adapter supports 4-wire balanced full duplex RS232 to RS422 communication, which allows two peer participants to operate in full-duplex. The transmission rate of 300 - 115200bps can be applied to point-to-point and point-to-multipoint networks.
This RS232 to 422 adapter is suitable for most applications, including industrial, commercial and any general office computer device. It is a RS232 to RS422 bi-directional, (meaning it communicates in both directions), reliable and cost-effective converter that easily lets you connect any RS422 device directly to your computer's serial RS232 COM port, efficiently converting standard RS232 to RS422 signals to full-duplex RS422 and vice versa. This particular converter utilizes the popular MAX491 processor chip from Maxim/Dallas Semiconductor and a supporting IC from Philips.
A simple and reliable RS232 to RS422 solution for most general and industrial communication needs. Header terminal board is included with each unit.
