Operating the PTX-PRO
This chapter describes how to use the PTX-PRO
Transmitter
(PTX-PRO).
3.1 Powering Up
Before powering up the PTX-PRO, make sure to connect the cables to the correct connectors
and fully mate and lock the connections.
CAUTION
Make sure the power supplied matches the power required by the unit.
When you set the
PWR
switch to
I
(on), the following sequence occurs:
1. The
PWR
LED above the
PWR
switch illuminates and changes colors from red, to green,
to amber, and finally to green and should remain green.
2. The alphanumeric display lights up and displays a self-test screen, then the version of
the firmware, and finally the default screen. The PTX-PRO uses the last settings in use
when power was turned off.
Test the performance of your PTX-PRO by setting up a link and transmitting and receiving video
and audio. If the PTX-PRO does not power up normally, see
Chapter 4,
Troubleshooting
.
3.2 Using the Display Screen
The screen on the PTX-PRO transmitter displays the values of the selected preset and the
output power. For example:
Preset #1
0.00W C 1
The Control switch lets you monitor status and set functions, displayed on the PTX-PRO
screen. The Control Switch cycles through information when you turn it clockwise (for
Monitoring information; see
Section 3.3
) or counterclockwise (for Setting parameters; see
Section 3.4
).
If you do not turn or press the control switch within 7 seconds, the screen reverts to the default
display. You can lock the display by pressing the Control switch; the display continues to update
the information. To unlock the display, press the Control switch again; the default screen
displays.
Use the
CHAN
and
OFFSET
Switches to select which channel to use. Verify the channel by
turning the Control switch clockwise to view the Channel Monitor screen, as shown in the
following example:
12712.500MHz
0.00W C 1
