Note:
Fire codes may require that cables in occupied building be installed in steel conduit.
Local government agencies may waive this requirement with the use of Plenum cables
which are standard cables encased in solid Teflon. Check codes for your area.
Note:
Equipment outages due to faulty installation are not covered by the Terrasat warranty.
Terrasat recommends following OEM procedures when making cables and
connectors.
J2 – M&C Interface The M&C interface is a 19 - pin circular socket connector used to
enable remote monitoring and control of IBUC operating parameters. Pin assignments
are shown in Table 3.4 . If the M&C port of the IBUC is going to be used, the cable
should be a shielded multi-conductor cable. For more information about fabricating
your own cable, see the IP cable drawing in Appendix G . An optional pre - assembled
IP test cable is available from Terrasat.
