Electrical Specifications 

The 2433 connects to a single USB port and provides four RS-232/422/485 software programmable serial 

ports. The 2433 utilizes a high speed UART with 128-byte Tx FIFO and 384-byte Rx FIFO. This chip features 

programmable baud rate and data rates to 921.6K bps. 

The input power is connected to pin 9 on each of the DB9 connectors for conveniently powering 5 VDC serial 

peripheral devices at a maximum of 500mA per port. Each DB9 serial port is fused at 500mA to protect the 

SeaLINK serial adapter from an over current situation. 

 

Do not connect pin 9 to any devices that have Ring Indicator (RI) enabled.  Doing so can result in 
damage to your device.
