Features
Max. 921,600bps RS-232C Serial Communication)
This product has 4 port RS-232C-standard COM ports. Baud
rates from 300 to 921,600bps can be set for each port. When
data is transferred at the high speed, it may not be transferred
normally, depending on the use environment such as the
external device and cable length used.
Possibly used as Windows-standard COM ports, using the
bundled driver library
Comes with a driver software that allows the boards to be used
under Windows in the same way as COM ports on the PC.
It supports to use under Windows-standard Win32 API
communication function, Visual Basic MSComm or .NET
Framework 2.0 SerialPoart class.
Each channel is equipped with separate 128-byte /
384-byte FIFO buffers for transmit and receive.
These are FIFO format, useful for high speed communications
and to reduce the load to the CPU when transmitting/receiving.
Compatible to USB1.1/USB2.0
Compatible to USB1.1/USB2.0 and capable to achieve high
speed transfer at Full Speed (12 Mbps).
