PCI2320 Data Acquisition V6.011
2.2.2 Physical ID of DIP Switch
DID1: Set physical ID number. When the PC is installed more than one PCI2320 , 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-place 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: place "ID3" is the high bit."ID0" is the low bit, and the black part in
the diagram represents the location of the switch. (Test software of the company often use 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.).
