RS-232/RS-485-422 ANC-6185 terminal block/RJ-45 version
RS485/422 Serial Adapters

The ANC-6185 adapters provide the designer with a low cost solution to change RS-232C level transmit and receive level signals into RS-485, and RS-422 differential level noise immune signals.


  • RoHS Compliant - Lead Free parts and manufacturing
  • Port powered for most applications
  • Transmit data at distances up to 4,000 feet (1,219 m)
  • Auto transmit (AutoXmit) enable is available at baud rates up to 64K baud
  • 4-wire full duplex or 2-wire half duplex operation
  • Baud rates to 1 MBaud
  • Terminal Block (ANC-6185T) or 8-pin RJ-45 Connector (ANC-6185R) versions
  • LED option for transmit and receive status (ANC-6185TL or ANC-6185RL)
  • Use with low cost CAT-5 cable
  • ANC-6085 version for multimedia applications intefacing to SMTPE DB-9

Hardware Flexibility
RS-422/485 - signal levels meet or exceed the Recommended Standards.  The RS-232C side mates directly with a PC serial port.  This makes the adapters an ideal solution for connecting external RS-485/422 equipment up to your PC compatible computer.

Software Compatibility
Because the adapter just converts RS-232C to and from RS-485/422 level signals, no specific software modifications are required to operate with off-the-shelf applications that use the serial communications port.  The data direction can be changed on the adapter by using either the RTS line or the AutoXmit feature of the adapter.

Easy to Use
Shipped ready for installation. Jumpers are pre installed for the most commonly applied  configuration and a comprehensive user's manual is included.

Every Antona product is built and tested to meet high standards of quality and reliability.  Our products are covered with a one year warranty.
