PRODUCT MANUAL - BARIX X8 - V01.05 - 10/26/2006
The command code 71 (hex 47) is used to erase the firmware of
a BARIX X8 device which is connected to the bus and whose
address is unknown (but serial parameters are correct). The
command can also be sent multiple times with different serial
parameters to find the device. The serial number of the device,
which can be found on a label on the unit (format xxx-yyy), needs
to be inserted into this block to address a specific unit. The block
is sent out as a Modbus broadcast.
After erasing the firmware the device will go into the download
mode with serial settings 19200,n,8,1.
