Description

The Maxim Command Module (CMAXQUSB) receives commands from an IBM PC through the USB to create an SPI™ or SMBus™/I²C-compatible interface. Maxim 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 development target is not supported. Rather, use the MAXQ2000 EV kit (available at www.maxim-ic.com/MAXQ2000-KIT) for this purpose.

The CMAXQUSB has been tested on Windows® 98 Second Edition, Windows 2000, and Windows XP®.
