Quatech Serial USB Adapters.
Quatech Serial USB Adapters. Description:
Quatech serial USB adapters are available in 1, 2, 4, 8, and 16 port units for RS-232 or RS-422/485 communication. All Quatech serial USB adapters enumerate themselves as standard COM ports, and can transfer data at speeds up to 460.8 kbps-a significant improvement over the 115.2 kbps maximum for a standard serial port.
The adapters are equipped with 16550 UARTs containing 16-byte FIFOs. These FIFOs, along with the FIFOs in the USB microcontroller, help relieve the CPU of excessive interrupts by buffering received and transmitted data, making Quatech USB adapters ideal choices for heavy multi-tasking environments.
In addition, Rs-422/485 adapters are configurable for full-duplex or half-duplex operation. Quatech serial USB adapters offer several attractive features that make them particularly convenient and easy to use. The adapters provide multiple ports via a single box with easily accessible connections. All the adapters are bus powered, so no external power supply is needed-an unusual feature in adapters providing such a large number of ports.
