We have a Jerrold Impulse 7000 model DP71.

Does anyone know what pressing the 'F' key then 1, 2, 3, 4 or 5 does?
The display
changes when these are pressed after the 'F' key.

Just curious.

Jim,

Those are the self diagnostics for that converter. Really useless for
the average person, but very helpful for us techs. F1 will tell wether
a signal is being received, and whether or not the barker frequency is
coming in. Fmute will restore the volume control to it top level....and
so on.

Here is a list of test codes for the JERROLD / GI
IMPULSE 7000 RF & BB units
____________________________________________________________
Press the following F key & Digit:::
------------------------------------------------------------

F 1 = Dynamic Diagnostics
This mode permits the monitoring of the descrambler,
the fm reciever,fm signal.
________________
- - - -
- 1 - - 2 - <<<<<-----DISPLAY
- - - -
- -A - -B
________________

Indicator A= on when unit sees a purchasable event
Indicator B= on when unit is addressed over the FM Data
Digit 1= State of the Descrambler<>Digit 2= State of the FM Reciever
C= Clear Channel O= Fm Data "OK"
S= Scrambled Channel E= Fm Data "ERROR"
b= Barker Channel
-= Disconnected
____________________________________________________________________

F 2 = Serial Number & Firmware Version

1st Number = Place Made 00=Japan 01=Taiwan
2nd Number = Year Made 1X (X=last digit of year) ie. 15=1985
3rd Number = Month Made 20=A=Jan 21=B=Feb 22=C=March 23=D=April
24=E=May 25=F=June 26=G=July 27=H=Augest
28=J=Sept 29=K=Oct 2A=L=Nov 2b=M=Dec
4th - 10th Numbers are the SERIAL NUMBER

Then you will see the Firmware Versions
_________________________________________________________________

F 3 = Firmwares i=Internal Firmware r=Expanision ROM version
_________________________________________________________________

F 4 = STATE Diagnostic Mode

Digit 1= r=Recieving DATA Digit 2 =O=Data "OK"
-=Idle E=DATA "ERROR"
t=Transmitting Data (2-way only)
___________________________________________________________

F 5 = STATUS Diagnostic Mode
Alternating Display of the FREQUENCY & LEVEL
There are 16 different differnet Levels (0-9 A-F)
___________________________________________________________

F 9 = CLOCK
Toggles clock On / Off

-----------------------------------------------------------

F 0 = Error Code

E0 = Normal
E1 = Reset Time Out or Good FM packet not recieved
E4 = Illegal Converter
E5 = Converter has default Address-Initialize again
E7 = Faulty ROM or wrong Initialization process
E8 = Site Code Error
E9 = Bad check pattern in Non-Volatile Memory
EA = Invalid serial number ( wrong checksum )

Enjoy,

f3 = firware version
F4 = visual representation of the data pilot (press F4 the disconnect

F1 is one way diagnostics and tells you weither your on a C=Clear
B=Barker and S=Scrambled channel. The second digit shows you the
condition of the data stream E=Error and O=OK.
