D
Set the transmission method used with the RS-232C interface which connects
the AJ71C24 to the external device. Both half-duplex and full-duplex transmis-
sions can be used for setting. If the half-duplex transmission is used, the
following settings should be made:
*Whether or not the AJ71C24 continues or stops transmission when the
AJ71C24 and the external device have begun sending data to each other at
the same time. (Prioritylnon-priority setting at simultaneous transmission)
.Whether or not the AJ71C24 transmits data again from the beginning or from
the point where transmission stopped when it restarts transmission. (Trans-
mission method when the transmission restarts.)
Set the transmission method which conforms to the specifications of the
connected device.
*When full-duplex transmission is used, settings with buffer memory
addresses IOFH, 110H, and 11 1 H are not required.
