The microprocessor reads the front panel switches every 1 second , and
stores the address or applies the special function described above. When
a serial stream is received, the microcontroller sets the output audio
switch to the state indicated by it’s corresponding bit.
2.4.3 - RF Frequency Changes (Replace U10) - The RF frequency
is programmed by the internal controller and the frequency programmed
is indicated on the rear panel. Figure 2.4 shows the location of the
controller. To remove U10 and replace it with a new controller at a
different frequency:
1.) Remove DC Power.
2.) Remove four (4) rear panel screws (see Figure 2.1).
3.) Gently pull the backplane and PCB assembly completely out of
the extrusion.
4.) With the wall power supply disconnected, and TAKING
PROPER ESD PRECAUTIONS Replace U10 and install new
controller. CAUTION! BE SURE PIN I OF U10 IS AS SHOWN
(Figure 2.4).
5.) Remove adhesive from the supplied LO frequency label
and place over existing label
6.) Always be sure power is removed when installing the PCB
in to the extrusion. Make sure the shield goes in the lower channel and
the PCB in the next channel above that in the extrusion.
7.) Gently push the backplane and PCB assembly completely in to
the extrusion so the front panel controls go through the front panel.
8.) Install four (4) rear panel screws.
9.) Connect RF to 210-01 and note that all LEDs are green.
