LAN Communication Links—Wiring Requirements
BMTW-SVN01F-EN 7
accommodate patch cables at each end of the link and signal losses in
intermediate wire terminations on the link.
IMPORTANT
Due to the high precision required when performing twisted-pair wire
terminations, Trane recommends that only qualified technicians with
the proper equipment handle all terminations and splicing.
Coaxial Cable—ARCNET
Use a 93 Ω coaxial cable (RG-62) for the Tracer Summit ARCNET link.
No other coaxial cable is supported.
You can order all ARCNET cables, adapters, crimp tools, stripper tools,
and other coaxial accessories from Trane.
For information about maximum cable length and maximum cable dis-
tance between two devices on a communication link, refer to Table 30 on
page 152.
Fiber-Optic Cable—Ethernet and ARCNET
Use fiber-optic cable for applications involving long distances. There is lit-
tle degradation of optic signals when using fiber-optic cable, and the
integrity of the signal is maintained in the presence of several sources of
electrical noise including lightning, EMI/RFI, voltage conductors, and
ground loops.
Use a duplex, 62.5 µm core glass fiber-optic cable with ST connectors for
the Tracer Summit Ethernet or ARCNET link. There are a variety of
cables available for different applications including indoor, outdoor,
burial, aerial, and duct.
You can order fiber-optic cables, fiber-optic modems, ST type crimp con-
nectors, epoxy connectors, and other accessories from Trane.
Note:
Cable installations must comply with both federal and local
codes. Plenum-rated cable is available to meet NEC Article 725,
which addresses flame resistance and smoke emission for
signal cables.
