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.
4.2 Configuration Overview
The following tables provide a description of the connectors on the DS560MB410EVM.

5.2.1 Establishing a Connection
1. Connect the computer to the DS560MB410 through a USB2ANY device and USB cable. If using a
DS560MB410EVM, then this is accomplished by connecting the included USB cable to the EVM and
computer. If using a stand alone USB2ANY device, then a connection can be made between the I2C pins on
the USB2ANY and the SMBus pins on the DS560MB410. A common ground connection is also required.
2. Ensure the DS560MB410 is in SMBus Target mode.
3. Select appropriate SMBus address by using the Target Address menu.
4. Select appropriate USB2ANY by using the USB2ANY Details menu.
5. Click Apply to connect to the device. The status indicator at the bottom of SigCon Architect will turn green to
indicate a successful connection.

5.3 High Level Page
The High Level Page is used to view channel status and configure commonly used channel settings. The
majority of device settings used in a typical use case can be configured through the High Level Page. Additional
device settings can be accessed through the Low Level Page.
5.3.1 Device Status
The Device Status tab shows a high level overview of the status of each channel in the DS560MB410. Although
a summary of channel settings can be viewed from this this tab, they cannot be changed from this tab. Channel
settings that are displayed in this tab can be changed from the Block Diagram tab.
