The Black Box® Parallel to Serial Converter IV is ideal for connections to an HP® JetDirect® parallel print server. It features an 8-position DIP switch to set the data rate from 300 bps all the way up to 38.4 kbps -with six data rates in between! It also senses if the serial device is DTE or DCE and adjusts accordingly. You can set the flow-control method (hardware or X-ON/X-OFF), parity, and word length with the external DIP switches.

The Parallel to Serial Converter IV is compact enough for laptop users, yet it can work with any desktop computer connected to a power outlet. The converter draws its power from the connected device and requires no external power supply.
