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. Therefore ARC330
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 unreliably. 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.
