Technote 3: Setting up PC-525 Channel Processors
PC-Series are fully agile Channel processors for the VHF/UHF band. The channel processor
has a built-in double FOS filter, so that it is possible to program the output with adjacent
channels.
IMPORTANT: Layout of the modules must be as shown above. Power Supply (FA-310/312)
must be located on the far left hand side and launch amplifier (PA-720) must be the next
module in the chain. Please look at the above picture.

WHEN PROGRAMMING
Programming of Modules
Ensure the following prior to programming:
•It is necessary to connect all the modules to the support frame SP-226 (code 9120130)
for the system to function.
•It is also recommended that you make the earth connection to the building using a cable
with a section of at least 4 mm.
•Ensure that you have the Alcad programmer PS-003 with firmware version 4.7 or later.
•Power supply/Control cable must be plugged into each module. DO NOT ADD OR
REMOVE modules without disconnecting mains supply power from wall outlet. Always
disconnect the equipment, and then reconnect it to the mains supply so that the
amplifier recognises the new module. Failure to do so can cause equipment to fail.

1.0 Programming of the Processor
To program the channel processor, place the programming switch in the ON (upward) position
which can be seen from picture below. When you turn the switch in the “ON” position the
programming indicator will light up. While the programming indicator remains lit, the channel
processor is ready to receive data from the PS programmer. When the channel processor has
been programmed, programming mode should be deactivated by placing the switch in the OFF
position. The programming indicator light will go out.
To start programming the equipment, Press any button on the PS-003 programmer to turn on
the programmer. The following screenshot below will appear.
You must then select the model you are trying to program. Scroll left or right using
the arrows until you get screenshot below
You will then need to press arrow down and you will then see the screen “Mode“. This
enables you to set the processor for analogue or digital which can be seen below

Press the arrow up once and you will then see the screenshot that enables you to
select the “Table Channel frequency” for the input/output frequency.
Then press the down arrow twice that will take you to screen you see the below which
requires you to enter the output frequency of the carrier you are processing without the offset.
You increase/decrease the values using the arrows or use the numeric keypad to
enter the frequency. Ensure if you enter the value using the numeric keypad you use the
decimal point. The Australian Analogue/Digital frequency table can be seen on the next page .
NB. The PC-series allows you to set the output frequency as processor (e.g. If Input
Frequency is 177.500 MHz then Output frequency 177.500MHz) or converter (e.g. If
Input Frequency is 177.500 MHz then output frequency is 620.500MHz) as they are fully
agile.

AUSTRALIAN DIGITAL/ANALOGUE FREQUENCY TABLE

Once you have entered the Output frequency press the down arrow to take you to
screenshot below which requires you to enter the input frequency of the carrier you are
processing or converting without the offset.
Once you have the entered the desired input centre frequency press transmit and you
will see the LED on the processor you are programming flash twice. This indicates it is
receiving the settings from the programmer. Now press down arrow to get to the next
screen below.
Please note offsets are required on some channels. e.g. Broadcaster Nine Metro requires
191.625 MHz so would set offset to + 1/6. For offset values look at table below to give you the
decimal Australian offsets.
Fraction
Offset
Decimal
Offsets
+ 1 / 6 +0.16
+ 2 / 6 +0.333
+ 3 / 6 +0.500
- 1 / 6 - 0.16
- 2 / 6 - 0.333
- 3 / 6 - 0.500
Press transmit to send the information then press down arrow to get to the next
screen below
Press transmit to send the information after you have set offset if required then press
down arrow to get to the next screen below
Change to 7MHz and then press transmit . Then press down arrow to get to the next
screen.
Bandwidth setting for Australia MUST ALWAYS be set to 7MHz.

You will be taken to the “Adjust Levels “screen which enables you to alter the output power
level.
The manual adjustment of the power output can be changed by pressing arrow
buttons to select desired output level. The range of the level is +25 to -25. Press transmit
to send the information.
You have now finished programming the channel processor, therefore programming mode
should be deactivated by placing the switch in the OFF (down) position. The programming
indicator light will go out.
