RS232 to RS422/RS485 converter, K2-ADE

The K2-ADE and K2-ADE-TB are mini RS232 to RS485 converters. The K2-ADE has a microprocessor for automatic RS485 driver control (ADE is Auto Drive Enable) and does not need RTS control on the half-duplex RS485 bus.They are powered via the RTS and DTR signals from the RS232 sub-D 9 port. On the RS485 side there is a sub-D 9 or screw terminal block connector.

Description

The K2-ADE is a non-isolated RS232 to RS485 converter for 1200-38400 baud, with Option 01 for 115200 baud. It contains a microprocessor for automatic RS485 driver control and does not need RTS Control. The K2-ADE is intended for RS232 to 2-wire RS485 conversion. It is not recommended for RS232 to RS422. It has a DB9 female connector at both ends. Features include ...

  • RS232 port-powered in most applications
  • Automatic Driver Enable (ADE)
  • 400 watt surge protection on RS485
  • Very low supply current
  • RS232 output swings above and below ground for maximum compatibility
