Further, Acromag recommends the use of
enhanced
Category 5 cable
(CAT-5e). This cable has all the characteristics of Category 5, but includes
enhancements that help to minimize crosstalk. Category 5e cable has a
greater number of turns-per-inch in its twisted pairs and its performance is
also more suitable for applications that make use of all four wire pairs for
simultaneous bidirectional data transmission (full-duplex). As such, it is
rated for frequencies up to 200MHz, double the rate of Category 5. This
cable is defined in TIA/EIA-568A-5 (Addendum 5).
Acromag offers the following cable accessories for use with this module:
Cable Model 5035-355
– A yellow, 3 foot long, single-shielded Category 5e
STP patch cable with drain wire and an RJ45 plug at both ends. Use this
cable to connect an Acromag 9xxEN I/O module to the Acromag 900EN-
S005 switch.
Cable Model 5035-360
– A green, 5 foot long, single-shielded Category 5e
STP crossover cable with a drain wire and an RJ45 plug at both ends. This
cable performs the Ethernet crossover function and is used to connect a PC
directly to an Acromag Series 9xxEN I/O module.
Note that you do not need to use a crossover cable to connect your PC to
this module if the Acromag 900EN-S005 switch is used between the PC and
module, as the switch is auto-crossing. However, you must use a crossover
cable when directly connecting your PC to a Series 9xxEN I/O Module
without the use of an auto-crossing switch or hub.
You may obtain cable in other lengths and colors as required for your
application from other vendors. For example, shielded CAT-5e cable is
available from the following vendors:
•
L-com Connectivity Products,
www.L-com.com
•
Pro-Link,
www.prolink-cables.com
For very noisy environments or in the presence of strong electrical fields, you
can obtain double-shielded CAT-5e cable and shielded RJ45 plugs from the
following vendors:
•
L-com Connectivity Products,
www.L-com.com
, see cable model
TFSC2004 and shielded plug T8P8CSR.
•
Regal
Electronics,
www.regalusa.com
, see shielded plug model
1003B-8P8CSR-C5.
Complete premium double-shielded Category 5e standard and crossover
cables in variable lengths can be obtained from Lumberg at
www.lumbergusa.com
(refer to their etherMate line). For example, specify
RJ45S-RJ45S-656/B/3M for a double-shielded, 3 meter straight cable.
Specify RJ45S-RJ45S-656/BX/3M for a double-shielded, 3 meter crossover
cable.
