Checking Power and Receiver
It is a good practice to check the main power and make sure it is
within specification. If there are no power indications on the
Gateway, perform the following procedure.
Verify Main Power
The Gateway uses the same DC power cable (Part No.
13065-000) for both the solar power and UPS option.
Complete the following steps to check the power for the unit and
the receiver.
Figure 92 – Gateway Power Plug
1. Disconnect the power plug to the Gateway. See
Figure 92.
2. Using a voltmeter, verify that there is 12 VDC present
between pins C+ and D- on the power plug.
3. If voltage is not present on the power plug or is less than
11 VDC, there is something wrong with the wiring or
the power source (solar power system or UPS).
See "Solar Power Information" on page 77.
Verify the RF Receiver
When the system is on, there are two LED lights labeled
RXMODE (red) and LOCKED (green) on the RF receiver board
that should be illuminated and remain on. See Figure 93 – page
72. If the two LED lights do not illuminate, check that there is
power to the unit.
