ARC250 User Manual 1.10 - 8
1.5: USB information
Uniden scanners use a standard Rs232 port for computer programming and
control. Uniden scanners do not have a USB port available. Therefor ARC250 is
developed to support standard serial comports.
For laptop PC's that do not have a serial port we advise to use a PCMCIA serial
port extender card.
Several manufacturers also sell serial<>USB converters. These converters
create a virtual software rs232 port and can work very unreliable. Because
USB is not the standard computer interface port for Uniden scanners, BuTel
does not support communication problems when a USB converter device is
used.
For support in case of communication problem customer should contact the
supplier/manufacturer of the usb device.
