Note
Huber+Suhner MXP cable assembles are not provided with this EVM. Users are expected to provide
cabling to connect to other boards and test equipment. For MXP cabling recommendations, refer to
Section 8 .
4 Setup
This section describes the jumpers and connectors on the EVM as well as how to connect, set up, and use the
DS560MB410EVM.
4.1 Modes of Programmable Communication
The DS560MB410EVM can be programmed in one of two modes, which are as follows:
1. SMBus target mode – provides full access to the DS560MB410 status and control settings through the
on-board USB2ANY. ADDR0 (J6) and ADDR1 (J11) headers are used to set the SMBus target address.
2. Controller mode – provides access to the DS560MB410’s EEPROM-programmable control settings through
an 8-pin EEPROM. A subset of SMBus register bits are writeable through the EEPROM. The EEPROM can
program up to 16 DS560MB410 devices.
For convenient use, a USB-to-mini USB cable provides a direct connection through the J27.
