ITS Core AP Connectors
Figure 1-5 shows the controls and connectors on the 1.4 GHz ITS Core AP and
Remote Antenna.
Note the following controls and connectors on the ITS Core AP:
• Ethernet Interface - The AP provides a 100 Base-T Ethernet interface with an
RJ-45 connector to connect the Core AP to the ITS Sync Unit.
The AP Ethernet interface provides data communications to and from the
IntelliVue Information Center over the ITS LAN infrastructure. It also presents
the 48Vdc power and synchronization signals required by the Core AP. The
synchronization signal is superimposed on the power supply voltage. You should
attach a ferrite block to the CAT 5 cabling (from the Sync Unit) no more than 20
inches (50 cm) from the RJ-45 connector to reduce electromagnetic (radiation)
interference. Table 1-1 lists the pin signals for the AP Ethernet interface.
• Serial Port - The serial port is used only for manufacturing purposes.
