Possible Error Conditions
If the download does not execute properly, verify the following:
• Verify that the COM port is correct.
• Verify that no other program is currently using the COM port, or that a previous DOS
window/shell is open that had used the desired COM port.
• Verify that no other copies of the WUpDate utility are currently running.
• Verify that a serial cable is used.
• Verify in the selected COM port’s Advanced Port settings that the FIFO buffers are selected
and that the receive buffer is set to High.
CAUTION: While upgrading, do not use your computer for anything else or switch between windows.
Close all other windows if necessary. If the upgrade was unsuccessful (such as during a power
outage), repeat the procedure.
