3.4.2 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
Check the instructions on page 16 before wiring, and perform correct wiring.
