Low Level Tab
In this tab, the user can find all of the register values that are on the DS125DF1610 board, including both
shared values and values unique to each of the input and output channels.
The Expand / Collapse all buttons can be used to show and hide all of the registers on the list. In order to
read the most recent settings from the board, use the Read All button to update the state of each of the
registers. In order to update only one of the registers, use the Read Register.
In order to adjust all of the registers in bulk, 4 additional buttons are available. The load config and save
config buttons will load and save the contents of all registers on the board. These .cfg files store all
registers in order with data in hexadecimal. The file can be edited in your favorite text editor. A simple way
to restore custom settings is to load your saved config files. The reset device button will reset the registers
and the board to their original configuration.
The fourth button is the broadcast button, which the user can utilize when it is necessary to change a
channel register on each of the 16 channels simultaneously.

Saving and loading the EEPROM configuration hex file can be performed with the Load from Hex File, and
