CALAMP WIRELESS NETWORKS INC. GPDB ユーザーズマニュアル

1.  Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions

to the position where the G3 unit is mounted.

2.  Terminate the end at each of the antenna positions with the appropriate connector for the antenna

used and make the connection.

3.  At the G3 position, cut the three cables to length and terminate with the appropriate plug. For the

transceiver and the auxiliary cables, use a Mini-UHF crimp plug using an appropriate crimping tool.
For the GPS, use a SMA connector.

4.  Positively identify the transceiver mini-UHF plug and connect to the left rear of G3.

5.  Positively identify the auxiliary receiver mini-UHF plug and connect to the front left of G3 to the RX

position.

6.  Connect the SMA connector to the GPS* position below the auxiliary connector position.

7.  Do not skip this last step, trust us; it is an important one. To complete the installation, tie-wrap to-

gether the auxiliary and the GPS antenna cables at a point about two inches in front of the unit. It will
be much easier hereafter to correctly identify which mini-UHF plug goes where. You DO NOT want
to cross the auxiliary plug with the transceiver plug.

To complete the physical installation and prior to testing G3:

•

 

Connect DC Power cable’s connector to G3’s until you hear a click as the two parts snap to-
gether.

•

 

Re-check that all other connections are secure (antennas, PC, etc.)

•

 

Switch vehicle ignition ON.

You are now ready to check for normal operation and to run the Radio Installation Software (WinRIS)
program for testing or trouble-shooting.

Check that the vehicle ignition is ON.

1.  Check for proper operation of the G3’s LEDs as per Table 1 on page 17.

2.  Using the WinRIS program and an in-line wattmeter, check forward & reverse power to confirm

main antenna installation (as per section 4).

3.  Using WinRIS, check the RF Data Link with a base station that can be heard (see section 4.3.3).

If user application and its base station are available, test the installation by going through a normal se-
quence of transmitting and receiving messages.
