Note
The setting for item “ RxD, TxD Active ”, also called “ TX, RX inverting ”, allows you to
determine the activity of RxD and TxD. We set it to “
Hi, Lo
”. If your motherboard BIOS uses
“
No
” and “
Yes
” to represent this item, you should set it to the same setting as the NV7-133R.
This means that you should set it to “ No, Yes ” in order to match the transfer and receiving speed.
If you fail to do so, you will not get an IR connection between the NV7-133R and the other
computer.
