Connecting the Ethernet
Cable
Connect the Ethernet cable to the SR-750 Series in the following procedure.
1
Preparation of Ethernet cable
First, rotate the connector screw and align the protrusion position with the
positioning pin position in the connector.
2
Connect to the SR-750 main unit
Align the protrusion position of the connector screw with the white mark
position of the SR-750 Series Ethernet port. Then, insert straight to avoid tilting
the connector.
3
Tighten the connector
Rotate the connector screw in the arrow direction until it stops (approx. 180
degrees) and tighten it.
NOTICE
• When connecting the connector, insert it straight so it does not
tilt. Otherwise, the connector pin may be damaged.
• Tighten the connector screw correctly. If it is not tightened
properly, the connector may become loose due to vibration, etc.
and connection failure may occur.
• Do not repeatedly bend the root of the connector of Ethernet
cable. Loose connection may result.
