Features
- Max. 921,600bps RS-422A/485 Serial Communication
The COM ports of this product support up to 921,600 bps. This product has one channel RS-422A/485-standard serial ports. - Compatible to USB 2.0/USB 1.1 and not necessary to power this product externally as the bus power is used
Compatible to USB 2.0/USB 1.1 and capable to achieve high speed transfer at Full Speed (12Mbps). Not necessary to power this product externally as the bus power of USB is used. - Possibly used as Windows, Linux-standard COM ports
Combining the product with our device driver COM-DRV makes it possible to use the product in the same manner as the COM ports of a PC. This product supports communication using DCB structures in the Win32 API and Linux-standard system calls. In addition, supplies a diagnostic program to confirm hardware operation and to perform a communication test with equipment. - Up to 127 converters can be installed on a single PC
Using a USB hub allows you to install up to 127 converters to a single PC. - Equipped with buffer memory for transmitting 128 bytes and receiving 384 bytes
This product is equipped with buffer memory for transmitting 128 bytes and receiving 384 bytes. These are FIFO format, useful for high speed communications and to reduce the load to the CPU when transmitting/receiving. - The control line for RS-422A/485 can be controlled and monitored by software.
The control lines for RTS+, RTS-, CTS+ and CTS- can be controlled and monitored using software.
