Installing the Link CX 41
4-2 Initial Configuration
interWAVE strongly recommends that the installer configure the Link CX at a depot or on-site before it is
mounted in its final location. This section includes instructions on how to configure the Link CX before it
is installed.
4-2.1 Connecting a Craft PC to the Link CX
The equipment used to configure the Link CX is a Craft PC with 10/100 Ethernet port and cable,
equipped with any current web browser and Adobe Acrobat Reader software. Figure 4-2 shows how to
connect the Craft PC and power to the Link CX for initial configuration.
Perform the following steps:
1 (Only for Link CXs with external antennas.) When you are configuring a Link CX with an
external antenna, connect the external antenna or a 2 W, 50 Ohm load to the antenna port.
This prevents harm to the Link CX internal circuits should full RF power be applied without a
load.
2 If necessary, use the instructions provided with your Craft PC operating system to change
the Craft PC ethernet address to 10.0.0.1.
3 Turn off power to the Craft PC to prevent damage to the Ethernet port receive circuitry.
4 Using a factory-supplied ethernet cable, connect an Ethernet-port equipped Craft PC to the
Link CX as shown in Figure 4-2.
5 MAKE SURE the antenna is pointing away from your work area before you apply power to
the Link CX, and MAKE SURE you stay at least 2 m (79 in.) from the front of the antenna
while the Link CX is connected to power.
6 Using a factory-supplied power cable, connect an external power supply to the Link CX as
shown in Figure 4-2.
7 Turn on power to the Craft PC and verify that the Ethernet port is active. Note that the
Link CX Ethernet switch will auto-detect transmit and receive pairs, and you should detect an
Ethernet connection within a few seconds of port activation.
The Link CX is now powered on and transmitting RF, and the Craft PC is now ready to log onto the
Link CX internal web main page.
Because you can expose yourself to harmful RF radiation any time the
Link CX is powered up, do not stand within 2 m (79 in.) of the antenna
during Link CX operation. The installer is responsible for ensuring that
the antenna is mounted in a place inaccessible to the public.
For faster configuration, make sure you have a filled-out copy of the
Radio Link Planning Worksheet from Chapter Three before continuing
with the rest of this section.
