OTEK Corp. announced its USB converter that allows the interface of any RS-232 or -485 equipment with any USB port without the need for an external power supply. The USB draws its power from the USB port and since the connectors match any existing PC DB9, the USB plugs to the DB9 on the existing equipment, requiring one cable (type A to type B) for the USB end. For RS-485, the USB comes with a screw terminal connector. The unit is supplied in modular form (no housing), and the board is conformally coated. Set-up software can be downloaded at no charge from www.otekcorp.com/software.htm. Applications include upgrade legacy peripherals, microcontrollers to USB, proprietary HiQ and TR wireless series to USB, games and instruments to USB.
