Installing the SiteNet 450 Network 3
The 30 m (99 ft) infrastructure cable (PN 40942-99) connects directly
to the SiteNet 450 and splits out to power via a TA-3 connector and
communications via dual female DB-9 connectors. The DB-9
connectors can connect to a GPS receiver and to a PC at the same
time. This is particularly useful for troubleshooting. This cable
requires its own power for the radio. It has no Conxall connector for
the MS750 GPS receiver. You can connect it to the MS750 with the
hammerhead connector B1/B2 cable PN 37382 that comes with the
base (reference) station kit. The cable has a TA-3 connector for power
to the radio only. The MS750 must be powered separately with the
cables provided in the base station. See Figure 3.8.
