Serial Interface

Communication with the external device is possible via a dedicated cable (and conversion adapter). For information on how to connect controllers and other types of equipment, refer to the corresponding device driver manual of the screen editing software.

NOTE:
  • You can switch the communication method between RS-232C and RS-422/RS-485 via the software.

  • The serial interface is not isolated. The SG (signal ground) and FG (frame ground) terminals are separated inside this product.

DANGER
ELECTRIC SHOCK
  • Make a direct connection between the FG (frame ground) terminal and ground.
  • Do not connect other devices to ground through the FG (frame ground) terminal of this device.
  • Install all cables according to local codes and requirements. If local codes do not require grounding, follow a reliable guide such as the US National Electrical Code, Article 800.
Failure to follow these instructions will result in death or serious injury.
