The
PC
can suspend the transmission of the “C-response Packet” data for the period less than
1000
milliseconds from
the
RE-350
by setting the
RTS
signal to
OFF
.

If the
PC
wants to suspend the transmission of the “C-response Packet” data stream on its half, the
PC
should
set the
RTS
line to
OFF
.
Once the
RE-350
recognizes the
RTS
of the
PC
is
OFF
, the
RE-350
will hold the transmission of the “C-response
Packet” data after the remaining maximum 3 byte data in its communication buffer is transmitted. The
application software on the
PC
can recognize if the
RE-350
is operating properly. The time period required for
transmitting the remaining data in the buffer will depend upon the communication speed of the
RS232C I/F
.
When the
PC
wants to resume the transmission, the
PC
should set
RTS
to
ON
immediately. The longest time
period to be able to hold the transmission is
1000
milliseconds. If the
PC
fails to set the
RTS
line to
ON
in
1000
milliseconds, the
RE-350
will stop the sequence to send the “C-response Packet”. The
PC
can not receive the
remaining C-response data any more.
Once the
RE-350
recognizes the
RTS
signal comes back to
ON
within
1000
milliseconds, the
RE-350
will resume
the transmission of the “C-response Packet” data.
