The OSN1500 SSQ2CXL1 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 code status and the single board executes 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 Q2CXL1 single board are shown in Figure 1 and Figure 2.
The location of jumper J7 and dial code SW2 on the Q3CXL1 single board is shown in Figure 3.
The description of jumper J3 on the Q2CXL1 single board and jumper J7 on the Q3CXL1 single board is shown in Table 1.
