The OSN1500 SSQ2CXL4 single board has jumpers to set the battery enable and dip switches to set the operating state of the single board.
The dip switches and jumpers are for single board testing and maintenance only.
After setting the BIOS dialing state and the single board has executed the corresponding operation, before restarting the single board, you need to reset the BIOS dialing code to zero (i.e., set the binary number to 0000). Otherwise, the single board can not enter the normal operating state.
The positions of jumper J3 and dial code SW1 on the SSQ2CXL4 single board are shown in Figure 1 and Figure 2.
