1.  Route good quality 50-ohm coaxial ca-

bles (e.g. RG-223) from each of the se-
lected 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 con-
nection.  

3.  At the  G3

       

 position, cut the three ca-

bles to length and terminate with the ap-
propriate plug. For the transceiver and 
the auxiliary cables, use a Mini-UHF 
crimp plug using an appropriate crimp-
ing tool. For the GPS, use a SMA con-
nector.  

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 con-
nector position.  

7.  Do not skip this last step, trust us; it is 

an important one. To complete the in-
stallation, tie-wrap together 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 cor-
rectly 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 together. 

•  Re-check that all other connections are 

secure (antennas, PC, etc.) 

•  Switch vehicle ignition ON. 
 
You are now ready to check for normal op-
eration and to run Dataradio test commands 
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 in section 3.1 

2.  Using the Dataradio test commands pro-

gram and an in-line wattmeter, check 
forward & reverse power to confirm 
main antenna installation (as per section 
4).  

3.  Using Dataradio test commands, check 

the RF Data Link with a base station 
that can be heard (as per section 4.3.2. 

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