The ICP-DAS I-7561 is a very cost-effective module to transfer serial data to
USB. This module allows you to connect your serial devices to systems using a USB 1.1 or 2.0 interface. When connecting the I-7561 to a PC, it will add one RS-232/422/485 port. It contains a "self-tuner" chip, which auto-tunes the baud rate and data formats to the RS-485 network. No power adapter is needed, because the module receives power from the USB port. Another feature is a high-speed 115.2 KB/s transmission rate which supports various OS, independent RS-232/422/485 Ports. Windows 98/ME/2000/XP and Linux drivers supported.
