3.0 Front Panel Facilities
RES: Pressing the RES (Reset) button reboots the unit. The unit will retain the
parameters of the previous settings.
LOC/REM: While depressing and holding the LOC/REM button and depressing and
releasing the RES button, the unit will toggle between the local and
remote mode of operation. In the local mode all parameters can be
controlled from the front panel facilities. The remote M&C is not
functional in the LOCAL mode of operation.
3.1 Local Operation
3.11 Changing Frequency
FSET: The FSET button activates the cursor. When depressed and released the
cursors will blink over one of the frequency digits.
CURSOR: Depressing and releasing the CURSOR button will cause the cursor to
move one frequency digit to the right. When the last digit is reached, the
cursor will jump to the first frequency digit. When the desired digit is
selected, the value of that digit may be changed.
UP: While in the FSET mode, the UP button increases the value of the
selected frequency digit.
DOWN: While in the FSET mode the DOWN button decreases the value of the
selected frequency digit.
When the desired frequency is selected depress and release the FSET
button. The cursor will no longer be displayed and the unit will be tuned to
the desired input frequency.
3.12 Changing Gain
When the unit is in the LOCAL mode of operation, the attenuation of the
input signal level can be changed to accommodate the variations in the
beacon input signal strength level. The attenuation is displayed in dB from
0 to 60 dB on 0.5 dB steps.

Once the unit has been tuned to the proper input frequency and the unit
indicates that it has locked to that desired carrier then the signal strength
the attenuation can be adjusted to achieve the desired operating signal
strength voltage.
UP: The UP button increases the value of the attenuation of the unit. The
maximum attenuation setting is 60 dB and is adjustable on 0.5 dB
increments.
DOWN: The DOWN button decreases the value of the attenuation of the unit. The
minimum attenuation setting is 0 dB and is adjustable on 0.5 dB
increments.
Using the above procedure, and when the unit is locked to the desired
carrier, adjust the gain such that the front panel signal strength indication
displays +7.50 VDC. The unit tracks the input signal strength over a 20 dB
range (0.5 V/dB). For a signal strength reading of +7.5 VDC, the unit will
track upwards to +10.00 VDC or a +5 dB increase in input signal strength
and downwards to 0.00 VDC or a –15 dB decrease in signal strength. The
signal strength is not only displayed on the front panel but is also available
for interfacing to external devices by utilizing the rear mounted terminal
plug.
3.2 Display
The front panel display is a 2 x 20 VFD (vacuum fluorescent display). The
display provides operating as well as alarm indication.
F : 930.00 to 2300.00 MHz on 10 kHz increments
ATTEN : 0 to 60 dB on 0.5 dB steps.
REM: Displayed in the lower left corner when the unit is in the REMOTE
mode of operation.
ALM: Continuously displayed if the unit is not locked to the carrier. The
green LOCK front panel LED will not be lighted.
SS: The signal strength voltage is displayed in volts DC. The range that
is displayed is 0.00 to +9.99 VDC. The normal optimum operating
level is +7.50 VDC.

5.0 Serial Communications:
REMOTE OPERATION
Note: The unit must be placed in the remote mode of operation to perform any serial
communication functions. Select the interface mode (RS-232 or RS-485) by
placing the rear mounted mode switch in the appropriate position.
The unit can be remotely monitored and commanded by use of an RS-485, 4-wire,
interface or an RS-232, 2-wire interface. The serial protocol is the same for both
modes and is as follows:
2400 Baud, No parity, eight data bits, one stop bit
(2400,N,8,1)
The unit can be assigned a Hex address within the range of values of 1 Hex to F Hex.
The assignment of the unit address is accomplished by the following sequence:
1. Place the unit in the REM (remote) mode of operation by depressing and holding
the LOC/REM button and depressing and releasing the RESET button. The unit
will toggle between the LOCAL and REMOTE mode of operation. When the
REMOTE mode is selected, REM will be displayed in the lower left corner of
the front panel display.
2. To select the address for the unit, press and release the UP or DOWN buttons
until the desired address is selected in the range of NO or 1to F where NO
means that no unit addressing is required and 1to F requires that the hexadecimal
equivalent of the selected address must be sent to communicate with the unit.
3. The unit needs to be left in the REM mode of operation for external control of
the unit.
To poll the unit for operating status when the unit is in addressing mode of 1 to F,
transfer the following sequence:
ADDRESS (HEX) <space>0<space>0<space>0<space>
The unit will respond back with the current operating settings and alarm conditions
AD=address, F=f4f3f2f1.k2,k1, ATT=AT3,AT2 . AT1, SS=v2,v1.m1,m2
Where address is the hex value of the unit, f4f3f2f1 is the operating frequency in
MHz, k2, k1 is the operating frequency in kHz, AT3, AT2, . AT1, is the attenuation
setting in dB from 0.0 to 60.0, v2, v1,m1, m2 is the signal strength in volts from 9.99
to 0.00.
If an alarm condition exits, the unit is out of lock, and then the signal strength voltage
will not be displayed and will be displaced with the word ALARM.
To change parameters of the unit transmit the following command string:

_____________________________________________________________________
ATLANTIC SATELLITE CORPORATION
MODEL ASC300LW
BEACON RECEIVER
9
Address (Hex) <space>f4f3f2f1<space>k2k1<space>at3,at2,at1<space>
Where address is the Hex value of the assigned address, f4 is the most significant
digit of frequency in MHz, k2 is the most significant digit in kHz, g3 is the most
significant digit of gain. The range of frequency is 950.00 to 2300.00 and the range of
attenuation is 0 to 600. If a frequency of less than 950 or greater than 2300 and/or an
attenuation of greater than 600 or a least significant digit of a number other than 0 or
5 is transmitted then ? will be transmitted back. The address, frequency in MHz and
kHz and gain must be simultaneously transmitted. They cannot be transmitted
independently.
The attenuation of the unit can be changed by transmitting any number from 0 to 600.
The least significant digit must either be a 0 or a 5. 0 corresponds to 0.0 dB
attenuation and 600 corresponds to 60.0 dB of attenuation. To change the attenuation
by 0.5 dB, the least significant digit must be a 5. For example, to change the
attenuation setting to 26.5 dB, the number string 265 must be transmitted.
An example to change frequency and attenuation is:
A (Hex) <space>1210<space>99<space>265<space>
The unit will change to 1210.99 MHz and an attenuation of 26.5 dB.
To poll the unit to see if the changes have been made transmit the following
sequence;
A (Hex) <space>0<space>0<space>0<space>
The unit will echo back the following:
AD=A,F=1210.99,ATT=26.5,SS=(As determined)
If there was an alarm conditions the unit would echo back at the end of the response
string the word ALM.
If the unit has NO selected as the address then no address is necessary as a preface to
the serial commands.
To poll the unit to see if the changes have been made transmit the following
sequence;
0<space>0<space>0<space>
All other commands are the same as described above with the exception that the
address character does not need to proceed the command structure.

11.0 Continuous Digital Streaming 351L STREAMING
The streaming option associated with the ASC351L series of beacon tracking receivers provides a
continuous data stream running at 9600 baud that contains signal strength level indication in
centiVolts as well as lock or alarm condition of the unit. A dedicated DB-9 (J4), on the rear of
theunit, provides the RS-232 streaming interface. The DB9, RS-232, pin out is:
Pin 2: serial output
Pin 5: ground
The protocol for the data stream is as follows:
9600,N,8,1
There is a 500 ms delay between transmissions.
The output data format is:
#(delimiter)1 or 0 (Lock or Alarm), space, followed by the signal strength voltage in centiVolts
(cV).
As an example, for signal strength of 7.50 Volts and the unit locked the data string would be:
#1 750
If the unit is not locked the data string would be:
#0 0
