5 ADS131M04EVM Initial Setup
This section explains the initial hardware and software setup procedure that must be completed for
properly operating the ADS131M04EVM.
5.1 Default Jumper Settings
After unpacking, the EVM is already configured with the default jumper settings. Figure 5 shows the
locations for the default jumpers.
Figure 5. ADS131M04EVM Jumper Default Settings
The default position of the JP6 jumper is across [1-2] at the top. JP6 sets the onboard oscillator frequency
to 8.192 MHz, used for the ADS131M04 in high-resolution mode. The default connection for JP9 is to the
left, so that the linear regulator is powering the system using 5 V from the PHI controller.
The default settings, as listed in Table 8 , includes no jumpers installed at JP5, JP7, and JP8. When
installed, JP5 disables the onboard oscillator, JP7 enables the EEPROM for write, and JP8 disables the
linear regulator.
Table 8. Default Settings
Jumper Position Function
JP1, JP2, JP3, JP4 [3-4] Sets common-mode to ground for device inputs
JP5 Not installed Disables on-board oscillator
JP6 [1-2] Oscillator frequency select, 8.192MHz
JP7 Open Disables write for EEPROM
JP8 Not installed Disables linear regulator power
JP9 [1-2] Selects device power from linear regulator
5.2 EVM Graphical User Interface (GUI) Software Installation
Download the latest version of the EVM GUI installer from the Tools and Software folder of the
ADS131M04EVM and run the GUI installer to install the EVM GUI software on your computer.
CAUTION
Manually disable any antivirus software running on the computer before
downloading the EVM GUI installer onto the local hard disk. Depending on the
antivirus settings, an error message may appear or the installer. The exe file
can be deleted.
