Connecting to external control devices
•
To connect the laser marker to the PC for control, use a commercially available RS-232C cross cable (9-pin).
•
In case of connecting to PLC, a type of the cable (straight or cross) differs depending on a manufacturer or a model.
Please follow the PLC manual.
•
To connect RS-232C terminal without using a commercially available RS-232C cable, connect only 3 signals of RxD,
TxD and GND and do not use other signals on the laser marker side.
•
The external controller may need a signal line connection (loop back line) other than RxD, TxD, or GND on the external
control device side depending on the specifications of the external control device. Read the instruction manual of the
external control device and connect it to the laser marker appropriately.

The loop back wiring on the external control device side shown in the above figure is just an example. The wiring
method varies depending on the specifications of each external control device. Read the instruction manual of the
external control device and connect it to the laser marker appropriately.
