Specifications of MAX5952AEVKIT

• Product: Controllers & Switches

The Hunt for active listeners button scans the entire
2-wire address space, reporting each address that is
acknowledged. The SMBusWriteByte transmits the
device address, command, and 1 byte of data. The
SMBusReadByte transmits the device address, a com-
mand, and then retransmits the device address and
reads 1 byte of data. The SMBusWriteWord and
SMBusReadWord operate the same, except 2 bytes of
data are used.
Problem: Software reports it cannot find the board.

and look at what device nodes are indicated for
USB. If there is an unknown device node attached to
the USB, delete it—this forces plug-and-play to try
again.
Are the SCL and SDA signals pulled up to
OPTO_VCC (CMAXQUSB VDD)? The CMAXQUSB
dip switch SW1 enables the on-board resistors on
the CMAXQUSB interface board. There must be
pullup resistors somewhere on the bus.
If using jumper wires to connect, are the SCL and
SDA signals swapped? Is the ground return missing?
