Modular Connector Connection
Modular connector is composed of a modular plug (male)
and a modular jack (female). Modular jacks are provided on
Infilex FC, and modular plugs will be crimped on LAN cables
as requires. Refer to the following procedure for crimping the
modular plugs on the LAN cables and connecting them to the
modular jacks.
For modular plugs, refer to the note 1 in
Specifications
section.
Procedure for modular connector connection
1) Strip outer sheath of a LAN cable end. Be sure not to
scratch or peel off any inner conductor sheath when
stripping the outer sheath.
Figure 16. Stripping the outer sheath
Make sure there are 8 inner conductors inside the outer
sheath.
2) Align the 8 inner conductors in a order specified by the
LAN cable manufacturer.
Figure 17. Alignment of the inner conductors
Alignment of the LAN cable inner conductors is shown in
the table below.

Note:
Color alignment shown above may not agree with your LAN
cable specification. Ask your LAN cable manufacturer for the
latest specification.
3) Insert the aligned inner conductors into a modular plug.
Figure 18. LAN cable insertion into a modular plug
Pin numbers of the modular plug in Fig. 18 shows the pin
number arrangement when you face the side with
contacts and cable stopper.
Before inserting the inner conductors into a modular plug,
even out the length with a nipper. Note that the modular
plug may not be crimped on inner conductors stripped
too long.
4) Crimp the modular plug with the crimping tool.
Completely insert the inner conductors into the modular
plug so that the contacts of the modular plug stick into
the inner conductors when the modular plug is crimped.
Crimped modular plug is secured on the LAN cable with
the cable stopper of the modular pug. Check the
contacts and the cable stopper when crimping the
modular plug.
5) Follow 1) to 4) for the other end of the LAN cable.
6) Check continuity of the LAN cable. Modular continuity
tester (Part No. DY7206A0000) facilitates continuity
check. At the same time, make sure that the inner
conductors are in order with the modular plug contacts
sticking in the conductors and that there is no cable
damage or disconnection.
7) Connect the modular plugs to the modular jacks. When
the continuity check is successfully completed, insert the
LAN cable modular plugs into the modular jacks of Infilex
FC and of user terminal/temperature sensor.
Be sure to completely insert a modular plug until it clicks.
