General Description

The Maxim Command Module (CMAXQUSB) receives

commands from an IBM PC through the USB to create

evaluation kits (EV kits) that make use of the

CMAXQUSB require custom software and can be

ordered together as an evaluation system (EV system).

Ordering information for EV systems is included in the

EV kit’s corresponding data sheet.

An EV system is an EV kit combined with an interface

board such as a CMAXQUSB and custom software.

Refer to the appropriate EV kit data sheet for quick start

and detailed operating instructions.

The use of the CMAXQUSB as a MAXQ2000 develop-

ment target is not supported. Rather, use the

MAXQ2000

EV kit (available at www.maxim-ic.com/MAXQ2000-KIT)

for this purpose.
