In case it is necessary to send and receive different voltage signals at the
same time, jumpers belonging to jumper groups DIR1 and DIR2 should
be placed in the appropriate positions. Refer to Figure 6. Jumpers HVS1,
HVS4 and HVS5 belonging to jumper group DIR1 as well as jumpers
LVS0, LVS1, LVS4 and LVS5 belonging to jumper group DIR2 are placed
so as to enable 5V to 3.3V voltage signal adjustment. Likewise, jumpers
HVS2, HVS3, HVS6 and HVS7 belonging to jumper group DIR1 as well
as jumpers LVS2, LVS3, LVS6 and LVS7 belonging to jumper group DIR2
are placed so as to enable 3.3V to 5V voltage signal adjustment.
