Precautions

This section describes wiring precautions.
 Handling of the Ethernet cable
• Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from your hand, dirt or
dust is attached to the core, it can increase transmission loss, arising a problem in data link.
• Check the following:
• Is any Ethernet cable disconnected?
• Is any of the Ethernet cables shorted?
• Are the connectors securely connected?
 Broken Ethernet cable latch
Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
 Connecting and disconnecting the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling a cable connected to the module may
damage the module or cable, or result in malfunction due to poor contact.
 Maximum station-to-station distance (maximum cable length)
The maximum station-to-station distance is 100 m. However, the distance may be shorter depending on the operating
environment of the cable. For details, contact your cable manufacturer.
 Network configuration
