• Maximum communication speed of 921.6Kbps
• Industrial grade temperature range of 40 to 85 degrees Celsius (IEC 60068 2 30/33)
• RS422/RS485 side able to absorb 400W surge from 10/1000 s peak pulse waveform
• ESD protection of level 4 (IEC 61000 4 2)
• No external power required when DTR signal line is enabled

The SystemBase CS 428/9at PRO2 RS232 to RS422/485 Serial Converter is the smallest converter currently available. It is an effective and efficient solution for overcoming the distance limitations of RS232 or connecting to industrial devices with an RS422/RS485 interface. No additional software is required for operation; a DIP switch can be used to configure the interface for either RS422 or RS485. Moreover, the CS 428/9AT PRO2 is fully compatible with the serial COM port on your PC.
