2.2.4 Physical ID of DIP Switch
DID1: Set physical ID number. When the PC is installed more than one USB2832 , you can use the DIP switch to set a
physical ID number for each board, which makes it very convenient for users to distinguish and visit each board in the
progress of the hardware configuration and software programming. The following four-byte numbers are expressed by
the binary system: When DIP switch points to "ON", that means "1", and when it points to the other side, that means
"0." As they are shown in the following diagrams: byte "ID3" is the high byte."ID0" is the low byte, and the black part
in the diagram represents the location of the switch. (Test software of the company often uses the logic ID management
equipments and at this moment the physical ID DIP switch is invalid. If you want to use more than one kind of the
equipments in one and the same system at the same time, please use the physical ID as much as possible.).

Chapter 4 Connection Ways for Each Signal
4.1 AD Single-ended Input Connection
Single-ended mode can achieve a signal input by one channel, and several signals use the common reference ground.
This mode is widely applied in occasions of the small interference and relatively many channels.
Figure 4.1 single-ended input connection
4.2 AD Double-ended Input Mode
Double-ended input mode, which was also called differential input mode, uses positive and negative channels to input a
signal. This mode is mostly used when biggish interference happens and the channel numbers are few.
Single-ended/double-ended mode can be set by the software, please refer to USB2832 software manual.
According to the diagram below, USB2832 board can be connected as analog voltage double-ended input mode, which
can effectively suppress common-mode interference signal to improve the accuracy of acquisition. Positive side of the
16-channel analog input signal is connected to AI0~AI15, the negative side of the analog input signal is connected to
AI16~AI31, equipments in industrial sites share the AGND with USB2832 board.
