The USB-RS422 cables are USB to RS422 levels serial converter. The cables include FTDIs FT232RQ USB to serial UART interface IC device, which handles all the USB signalling, and protocols, plus an appropriate transceiver. The cable provides a fast, simple method to connect equipment with an RS422 interface to USB. Features: " Entire USB protocol handled by the electronics in the cable. " UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity. " EIA/TIA-422 and V.28/V.24 communication interface with low power requirements. " Internal EEPROM with user writeable area. " Data transfer rates from 300 baud to 3 Mbaud. " Visual indication of Tx and Rx traffic via LEDs in the transparent USB connector. " Extended temperature range (-40°C to +85°C). " Electronics available as separate PCB.
