Communication Protocol Setting
In the PNC-3100, the interface type (Parallel or Serial) is differentiated automatically. The distinguished interface is
memorized until the power is turned OFF. It can not be varied while the power is ON. When changing the differentiated
interface, turn the power OFF and then ON again, then transmit data.
In the case of serial connection, the controller sends and receives data under the communication protocols set using
the PNC-3100 DIP switches.
NOTICE
The PNC-3100 cannot receive data properly when the computer software and PNC-3100 communication
parameters differ.

DIP switches
Set the DIP switches on the bottom panel
to the ON or OFF position as needed.
• Setting of the stop bit, data bit, parity
check, baud rate and handshake can be
done with these DIP switches.
• An object with a fine tip such as a ballpoint
pen will make ON/OFF settings of the
DIP switches easier.
Please use ample caution to avoid
breaking the DIP switches by apply-
ing unnecessary force.
