When the FX
2N
-232IF receives the RS (request
to send) signal at its carrier to send (CS) pin, the
FX
2N
-232IF transfers signals as if the external
equipment exists.
*1. It is not necessary to connect the CD signal if
monitoring the CD signal is not required.
For the CD signal, the 232IF indicates only the
status.
*2. The 232IF indicates only the status.

-232IF
In the interlink connection mode, the 232IF can
receive data larger than 512 bytes which is the
upper limit of the received data buffer in the
232IF.
*1. In this mode, the request to send (RS) signal works
as the receiving enable signal for the 232IF.
When the 232IF receives data beyond the
maximum number of receivable bytes, it turns OFF
which works as the receive ready signal (RS signal)
to ask the external equipment to stop sending. At
this time, by withdrawing the data located in the
received data buffer using a sequence program,
the 232IF can receive remaining data.
*2. The 232IF indicates only the status.
