(2) Precautions
(a) Laying Ethernet cables
• Place the Ethernet cable in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
• Do not touch the core of the connector of the cable or the module, and protect it from dirt and dust. If any oil
from your hand, or any dirt or dust sticks to the core, it can increase transmission loss, causing data link to
fail.
• Check the following:
• Is any Ethernet cable disconnected?
• Does any Ethernet cable short?
• Are the connectors securely connected?
(b) Broken cable latch
Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
(c) Connecting and disconnecting the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable connected to
the module may result in damage to the module or cable or malfunction due to poor contact.
(d) Connectors without Ethernet cable
To prevent dust from entering the module, attach the provided connector cover.
(e) Maximum station-to-station distance (Maximum Ethernet cable length)
The maximum station-to-station distance is 100m. However, the distance may be shorter depending on the
operating environment of the cable. For details, contact the manufacturer of the cables used.
(f) Bending radius of the Ethernet cable
There are restrictions on the bending radius of the Ethernet cable. Check the bending radius in the
specifications of the Ethernet cables used.
