Power Up
1. Verify the power cable is properly connected to the
TCU rear panel POWER connector.
2. Verify the power cable is properly connected to the
TXU front panel POWER connector.
Note If your TCU does not have a DC ON COAX
switch, go to step 4.
3. Turn the recessed DC ON COAX switch on the front
panel of the TCU until the screw slot of the switch
points to OFF.
4. Turn the recessed DC ON COAX switch on the front
panel of the TXU until the screw slot of the switch
points to OFF.
5. Verify all coaxial cables and connectors have been
properly connected.
6. Connect the TCU and TXU to DC power of the correct
voltage and polarity.
If you are unsure of the power requirements or the
connections, refer to the “Installation” Chapter on
page 6-1 (Part of the STRATA TX System Technical
Reference Manual only).
If the TCU and TXU are both powered from the
optional STRATA ACU, connect the ACU input to AC
power and verify the TCU and TXU branched power
cable is connected to the ACU DC OUTPUT
connector. Set the ACU power switch to I (on) and
verify the ACU power LED is on.
If the TCU and TXU are powered from a source other
than an ACU, turn that power source on.
7. Set the TCU PWR switch to I (on).
8. The normal power-up sequence is as follows:
- The Status LED above the PWR switch should
illuminate and should change colors from red, to
green, to amber, and finally remain green.
- The alphanumeric display should light up and quickly
display a self-test screen, then the version of the
installed firmware, and finally the Main Screen.
Some typical screens are shown in Figure 3-12. The
exact screens will vary depending on installed
hardware.
- The TCU will typically power up using the last settings
in use when power was turned off.
- If the TCU does not power up normally, refer to the
“Troubleshooting” Chapter on page 4-1.
