Installation - Array Solutions PowerMaster Series Manual

INSTALLATION DETAILS - DISPLAY HEAD AND
COUPLER LOCATION
The Display Enclosure is designed to be either table-top or 19-inch rack
mounted with the optional rack mounting plates. You can mount one or
two meters side by side in a standard 19-inch rack with the available
mounting plates in a 2U high space. If using the Display Enclosure as a
table top or shelf mount, simply place it into a position that is easily
seen, but be careful not to place it on top of an amplifier in a way that it
blocks the cooling of your amplifier. Choose a suitable location for the
Directional Coupler and mount it as well. We suggest mounting it with
an adapter right at the output of your amplifier. Be sure that you mount
the Directional Coupler close enough to the Display Head so that the
supplied cable can reach. If you require a longer cable, any shielded ¼"
"Stereo" jumper cable will suffice. If you use a longer cable, test it for
accuracy and RF immunity.
Connect a 12-15V DC power supply cable with 2.1mm plug to the
Display Head. The center pin is the "+" side of the DC power plug. Wire
your cable to a clean DC power source. Remember that some switch
mode or cheap wall warts are RF "noisy". The Display Head is protected
against polarity reversal.
DIRECTIONAL COUPLER WIRING - Since the purpose of the
PowerMaster is to provide an indication of the match of your antenna
system to your transmitter, it is critical that the Directional Coupler be
installed as the first element after the antenna jack on your transmitter or
amplifier and before a tuner. Connect from your transmitter's antenna
jack to the SOURCE connector on the Directional Coupler.
PowerMaster Series RF Wattmeter
The standard Directional Coupler comes with SO-239 connectors. You
can order optional "N" connectors or 7/16 Din connectors for very high
power operation.
If you are using an amplifier, install the Directional Coupler after your
amplifier. Connect the cable that goes to your antenna system to the
ANTENNA jack on the Directional Coupler. You may use the VSWR
protection circuitry if desired.
Recheck your cables/adapters and fasten them down appropriately. Turn
on the power to the Display Head. You should see the firmware version
number displayed, and then the PowerMaster will go to its normal
operational state.
Note that the display will become dimmer after 2 minutes of not
sensing power, and completely dark after 10 minutes of not sensing
power. This feature allows you to keep the meter on all the time and
not reduce the lifetime of the display.
