  1. KD485-STD

    KD485-STD

    The KD485-STD is an interface converter/isolator only and is baud rate and character format independent. Its main application is in isolated conversion between RS232 and RS422. It can also drive a 2-wire RS485 bus if the RS232 host provides RTS Control. Requires a power supply in the range of 7-35 volts at typically less than 2 watts.

    Port 1 is RS232. Port 2 is RS422 or RS485.

  2. KD485-ADE

    KD485-ADE

    The KD485-ADE is similar to the KD485-STD but inserts a microprocessor (with two serial ports) into the data path which provides data buffering and facilitates baud rate etc conversion. The KD485-ADE is a highly versatile converter which is intended for RS232 to RS485 conversion but works equally well for RS232 to RS422, half duplex and full duplex.

    Port 1 is RS232. Port 2 is RS422 or RS485.

  3. KD485-PROG

    KD485-PROG

    This interface converter is similar to the KD485-ADE with the addition of a 32kbyte EEPROM into which application specific data conversion programs can be loaded. It is typically used for protocol conversion applications. A MODBUS RTU SLAVE library is available to speed up the development of custom Modbus RTU converters.

    Port 1 is RS232. Port 2 is RS422 or RS485.

  4. KD485-STD-232-232

    KD485-STD-232-232

    The KD485-STD-232-232 is an interface converter/isolator only and is baud rate and character format independent. Its main application is isolation between RS232 and RS232. It requires a power supply in the range of 7-35 volts at typically less than 2 watts.

    Port 1 is RS232. Port 2 is RS232.

  5. KD485-ADE-232-232

    KD485-ADE-232-232

    The KD485-ADE-232-232 is similar to the KD485-STD-232-232 but inserts a microprocessor (with two serial ports) into the data path which provides data buffering and facilitates baud rate etc conversion.

    Port 1 is RS232. Port 2 is RS232.

  7. KD485-STD-422-422

    KD485-STD-422-422

    The KD485-STD-422-422 is an interface converter/isolator only and is baud rate and character format independent. Its main application is isolation between RS422 and RS422. It requires a power supply in the range of 7-35 volts at typically less than 2 watts. The KD485-STD-422-422 does not support RS485 because its interface drivers are permanently enabled, but can be used for RS485 monitoring.

    Port 1 is RS422. Port 2 is RS422.

  8. KD485-ADE-4XX-4XX

    KD485-ADE-4XX-4XX

    The KD485-ADE-4XX-4XX is similar to the KD485-STD-422-422 but inserts a microprocessor (with two serial ports) into the data path which provides data buffering and facilitates baud rate etc conversion. It can also be used for connecting 2-wire RS485 slaves to a 4-wire RS485 bus, or vice versa. Subject to minimum intermessage gaps it can also operate as a 2-wire RS485 repeater.

    Port 1 is RS422 or RS485. Port 2 is RS422 or RS485.

  10. KD485-STD-232-20MA

    KD485-STD-232-20MA

    The KD485-STD-232-20MA is an interface converter/isolator only and is baud rate and character format independent. Its main application is in isolated conversion between RS232 and 20ma loop (TTY). It requires a power supply in the range of 7-35 volts at typically less than 2 watts. If the built-in 20mA current source is to be utilised, the power supply should be 24V.

    Port 1 is RS232. Port 2 is 20mA loop (TTY).
