This section explains the settings in order to communicate in the pairing open method
by giving an example.
• Connection No. 1 and 2 are used.
(When connection No. 1 is specified at pairing open settings, connection No. 2 is
automatically used as pairing.
Therefore, connection No. 8 cannot be specified as pairing.)
b11 b10 b9 b8
(1) Fixed buffer (BFM#32 b0)
In the open pairing, the applicable connection No. and the subsequent
connection No. are paired. Set the applicable connection No. to "Receive" and
the next connection number to "Send".
(2) Existence confirmation (BFM#32 b1)
If existence confirmation is going to be executed, set the receiving connection to
"Confirm" and the sending connection to "No confirm".
If existence confirmation is not going to be executed, select "No confirm" for both.
(3) Pairing open (BFM#32 b7)
Set the receiving connection to "Pairs" and the sending connection to "No pairs".
(4) Protocol (BFM#32 b8)
Both "TCP/IP" and "UDP/IP" are allowed.
