RS232 to RS422/RS485 converter, K2

The K2 and K2-TB are mini RS232 to RS422/RS485 converters. They are powered via the RTS and DTR signals from the RS232 sub-D 9 port. On the RS422/RS485 side there is a sub-D 9 or screw terminal block connector.

Description

The K2 is a non-isolated RS232 to RS422 or RS485 converter for 0-115200 baud. It is primarily for RS232 to RS422 conversion. For RS485 use, RTS Control is required from the RS232 device. The K2 can also act as a Master on a 4-wire "RS485" bus. The K2 has a DB9 female connector at both ends.

  • RS232 port-powered in most applications
  • Very low supply current
  • RS232 output swings above and below ground, for maximum compatibility
  • Sony professional compatible (also known as SMPTE) RS422 pinout
