5. Connecting to the Network
The following describes how to connect the Ethernet module to the 100BASE-TX,
10BASE-T, 10BASE5 and 10BASE2.
POINT
Sufficient safety precautions are required when installing the 100BASE-TX,
10BASE-T, 10BASE5 and 10BASE2 networks. Consult a specialist when
connecting cable terminals or installing trunk line cables, etc.
5.1 Connecting to the 10BASE-T/100BASE-TX
<Connection procedure>
1) Connect the twisted pair cable to the
hub.
2) Connect the twisted pair cable to the
Ethernet module.

5
POINT
During the high-speed communication (100 M bps) via 100BASE-TX
connection, a communication error may occur due to the effect of high
frequency noise from devices other than programmable controller in a given
installation environment.
The following describes countermeasures on the QJ71E71-100 side to prevent
the effect of high frequency noise for construction of network system.
(1) Wiring connection
• Do not bundle the twisted pair cables with the main circuit and the power
wires, and do not install them close to each other.
• Make sure to place the twisted pair cables in a duct.
(2) Communication method
• Data communication with an external device is performed using TCP/IP
communication.
• Increase the number of communication retries as necessary.
(3) 10 M bps communication
• Communication is performed at a data transmission rate of 10 M bps by
changing the connection hub for the QJ71E71-100 to a hub capable of
handling 10 M bps.

B
<Connection procedure> ( 1)
1) Slide the retainer toward the
direction B as shown in the
figure.
2) Push in the AUI cable connector
all the way.
3) Slide the retainer toward the
direction A as shown in the
figure.
4) Confirm that the AUI cable is
locked.
1: Do not connect the AUI cable while the power to the module installed
station is on.
(2) Wiring to the external power supply terminal (DC power supply for
transceiver ( 1))
The following explains how to connect a cable to the external power supply
terminal (DC power supply for transceiver).
1) Strip the cable jacket back 13mm. ( 2)
The applicable cable size is 0.13mm2(AWG26) to 2.5mm2(AWG14).
13mm
(0.51 in.)
2) Loosen the terminal screw and insert the cable into the terminal.
3) Tighten the terminal screw within the torque range shown in Section
3.1.
1:Use a transceiver with a function that is generally called SQE TEST or heart
beat (a transceiver function that emits signals to notify whether the
transceiver is operating normally at the end of communication).
2:If the wire strip length is too long, the conductive part is exposed and it may
increase the risk of electric shock or short circuit between the adjacent
terminals. If the wire strip length is too short, it may result in poor contact.
