SUMMARY

There is a lot to know about making good Cat . 5 cables
with RJ45 connectors . The purpose of this guide is to
cover the basics of crimping Cat . 5 cable; which is vital to
LC&D system installation, operation and maintenance .
Please follow the steps outlined in this guide thoroughly; if
you have any questions or need assistance call Tech Sup-
port (800) 345-4448 .

STABLE DATUMS ON CRIMPING CAT.5

1 . Ethernet cabling standards are different from our GR
2400 Cat . 5 cabling . Ethernet cables max out at 100m
(330ft) . RS485 can go to 4000ft .
2 . A cable can pass a LAN cable test but still cause an un-
stable bus, no matter how expensive the cable tester .
3 . Inconsistent crimping causes problems in a network . The
expression "weakest link in the chain" really applies on a
DAISY CHAINED system . If there is a bad connection in
the chain, nothing on the far side of that connection can
communicate back to the beginning of the chain .
4 . Inconsistent crimps that may work fine on an Ethernet
network may yet cause problems on a "multi-drop" or
"daisy chained" bus .
5 . Professionally made wires use stranded RJ45 cable . Al-
ways use stranded wire . It is only slightly more expen-
sive than solid cable and yet can save hours and hours
of tracking down and correcting bad crimps .
6 . LC&D can only recommend EZ-RJ45 brand modular
connectors .
7 . The EZ-RJ45 brand crimper that also cuts off the wires is
NOT recommended since it still produces bowed crimps
no matter how many times you hit the crimp . The recom-
mended crimper is provided in the LC&D crimper kit .
It's also widely available from other suppliers who private
label the same crimper . They all look the same .

8 . When you crimp an RJ45, always crimp it down multi-
ple times to ensure properly aligned and evenly seated
contacts on the connector .
9 . Never bend Cat . 5 with a radius of less than 1" . Cut out
and throw away sections of cables that have been kinked
and straightened out . They can cause drop outs .
10 . Always VISUALLY inspect crimps . This one action can
save a lot of work . Always follow up with a cable tester
once both ends of the cable have been crimped .
