The Dataman 48UXP has two interfaces: USB and Parallel. You can choose either
one to connect the unit to your personal computer.
USB:
If you wish to use the USB interface then you will need to install the 48UXP USB
software. The Dataman 48UXP supports both USB 1.1 and USB 2.0. Dataman
recommends USB 2.0 for performance reasons.
This software is currently only available in Beta form and supports the
following operating systems: Microsoft® Windows® 98SE, ME, 2000, and XP.
Parallel:
If you wish to use the parallel interface on your personal computer then please
use the latest Dataman 48XP/UXP software. This software currently supports the
following operating systems: Microsoft® Windows® 9x, ME, NT, 2000, and XP.
Device Support and Performance Issues:
The Dataman 48UXP uses a very data intensive handshake between the personal
computer and the programmer during the programming and verifying stages. USB is
designed for large data transfer between the host and the USB device. The 48UXP
is not able to take full advantage of this due to the bulk transfer nature of
the USB bus.
This causes the handshake to be very inefficient, furthermore this overhead
causes a reduction in programming speed and verification of microprocessor
devices under the USB interface.
Due to this issue, we have removed certain MCU devices from the USB driver
software. If the speed decrease is an issue or the MCU is not supported under
the Dataman 48UXP (connected to USB) then we recommend that you install the
Dataman 48UXP on a parallel port and run the Dataman 48XP/UXP parallel port
software as mentioned previously.
