Most of the main window’s available functions and a
few more can be evaluated by using the pulldown
menu.
There are two methods for communicating with the
MAX5945: through the Main Window Display or through
the general-purpose Two-Wire Interface Diagnostics
Utility using the ViewInterface menu. The utility config-
ures the I
such as Start and Stop bits, Acknowledgements, and
clock timing. The two-wire Interface screen allows you
to send general-purpose I
mands using the SMBus-WriteByte/ReadByte and
WriteWord/ReadWord commands. For more informa-
tion on the differences between the I
wire interface and an SMBus interface, read the appli-

the Main Window display no longer keeps track of
changes sent to hardware. The EV kit can be reinitial-

The Hunt for active devices button scans the entire
two-wire address space, reporting each address that is
acknowledged. The SMBusWriteByte transmits the
device address, command, and one byte of data. The
SMBusReadByte transmits the device address, a com-
mand and then retransmits the device address and
reads one byte of data. The SMBusWriteWord and
SMBusReadWord operate the same, except two bytes
of data are used.
Problem: Cannot find MAX5945 EV kit parallel port
connection.
Ensure that the I/O extension cable is connected to a
parallel port, and not a SCSI or other type of port. If a
local printer driver is installed, temporarily disable it.
The software will not work if the program icon is
dragged onto the Windows desktop; instead, install the
software into a subdirectory, such as C:\MAX5945.
