The K422-ISOL is an isolated RS232 to RS422 converter for up to 38400 baud. It is intended for RS422 i.e. full-duplex point to point communication. It can also act as a Master on a 4-wire "RS485" bus.

  • Isolation 100% tested at >1000V AC
  • Plugs directly into IBM PC DB25 serial port
  • Very low cost
  • No separate power supply required in most applications
  • Baud rate independent 0-38k baud
  • Controlled slew rate driver for low emissions
  • MIL-STD conformally coated circuitry
  • Surge-protected RS422 or RS485 inputs
  • Thousands sold since 1993

Do not confuse these isolated models with imitations which claim to be self-powered but which in fact require power to be supplied to both sides of the converter, or which require about 40mA - far too much for any PC interface to supply.
