The DSP-200/300 adds two fully independent serial ports to a host PC. Each
port can be configured as RS-485 by using a 60 ohm resistor, or as RS-422 by
connecting an 100 ohm resistor. Any combination of RS-422 and RS-485 ports can
be used. The DSP-200/300 serial ports are implemented with 16750 UARTs that
provide 64-byte transmit and receive FIFOs, making the card ideal for use in
multi-tasking environments.
The card can be configured for full-duplex or half-duplex operation. To further
increase performance, we have created an auto toggle feature for the RS-422/485
transmitter in half-duplex mode that permits the hardware itself to regulate
data flow by only driving lines while actively transmitting--providing increased
speed and convenience over the older software controlled method.
Software is included to install and configure the DSP-200/300 for use with Windows
95/98/Me/NT/2000/XP, Windows CE, Linux and OS/2. |
