Description Technical Specs Drivers & Downloads
 
Null modem adapters are used to connect two DTEs (computer, terminal, printer etc.) directly using a RS-232 serial cable. The original RS-232 standard only defined the connection of DTEs with DCEs (i.e. modems).

With a null modem adapter, the Transmit and Receive lines are crosslinked. Depending on the purpose, one or more handshake lines are cross-linked. Several wiring layouts are in use because the null modem connection is not covered by a standard. B+B SmartWorx’ Null Modem adapter comes with a variety of connector options and pin outs to cover most common applications
Features
  • Interconnect two devices with similar DTE ports
  • Reverse Pin 2 (Transmit Data) and Pin 3 (Receive Data)
  • Connect TD to RD, DTR to DSR, and RTS to CTS
  • Transfer port power from host to peripheral
  • Ideal for use with port powered converters from B+B SmartWorx
