Just press the button and use the configuration program. Serial ports on USB allow further use of existing devices, even when the computer doesn't offer serial ports. Now the USB-2COM-PRO is extremely flexible in offered communication standards. Besides the classical RS232 and RS422 it offers six variants of the RS485 operation. The often required Termination and Polarization (BIAS) is also provided by built-in hardware, and it is controlled by the same configuration software. The USB 2.0 interface enables the high speed serial ports (max. 3Mbps, 128 byte FIFO) for high speed communication, even in heavy loaded systems. Unique features reduce the system load. The serial ports also allow unusual speed settings like 500kbps.   Hardware Specifications Serial interface 2 x RS232/422/485 configured by software RS485 Termination and Polarization configured by software Connectors DB9 male Speed RS232: up to 500kbps RS232 RS422: up to 3Mbps RS485: up to 3Mbps Available Modes RS232 full duplex RS422 full duplex RS485 4-wire, full duplex RS485 2-wire, half duplex, with echo RS485 2-wire, half duplex, without echo Signals RS232: TxD, RxD, RTS/CTS, DTR, DSR, DCD, RI, GND RS422: Tx+/-, Rx+/-, RTS+/-, CTS+/-, GND RS485 4-wire: Tx+/-, Rx+/-, GND RS485 2-wire: Data+/-, GND USB Interface USB 2.0 Bus powered No external power supply Driver Windows 2000 to Windows 7 Windows Server 2000 to 2008 R2,  both x86 and x64 Editions.
