Jerrold Impulse "F" codes
Hipster
I bow down to you, my technically literate brethren.
Anyone out there feeling beneficent enough to post or e-mail me a
listing of the possible "F" codes I can use to see what's happening
with my Jerrold Impulse box? I know that F, Mute resets my
converter's volume to the "optimal", but I don't know what the other F
codes do, other than to induce strange output in my 2-digit red LED
display! I'm curious...I like to know HOW things work, not just that
they DO work. It is nowhere in the user guide I got from TimeWarner.
Can I buy an installer's guide or a shop manual for this box from
somewhere?
Thanks!

I would also be interested in any additional information on the Jerrold Impulse
box. I recieved NO documentation from my cable company on it.
Thanks.

Sorry you've had trouble getting tech support, I'll answer what I know....
The F key is partly for troubleshooting, and being in production (not in customer
services) I don't know all of those...but the F key is also a "quick function key" which
allows you to do a couple of things quicker than through the menus. If you hit F then
Mute then it changes the volume to the "optimal sound level". If you set the volume
there, then adjust your TV to what you consider the optimal level for you, then you can
always get to that level quickly. Then you can adjust the volume up a little when your
wife runs the dishwasher or down when you're watching Rambo in the middle of the night!
(if only I could get Dad to do that!) The other functions are:
F, then Delete Clears all the Favorite channels. The best reason I can see for this is
that you can recreate your favorite channels whenever. Each time you sit down you can
clear all the favs, then as you scan through and find programs you want to watch you hit
Prog (program) and it'll remember that channel. After you've surfed through the whole
lineup, then you can just keep hitting the FAV button and surf through just those shows.
Cool, eh?
Then there's F, select...which cancels PPV purchases
And lastly F, CATV (could be the ON/OFF on some remotes) which takes you straight to the
sleep timers...so you can set the TV to turn off in, say, an hour...so after Rambo goes
off, the TV turning off will remind you to wake up and go to bed :)
Hope this helps. If you have any other function questions, I'll try to help. As far as
trouble shooting stuff...I have little knowledge. Not none, just very little :)

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 )

I can't find the book.. but i do have access to the codes. I know some of
the codes.. and they are as follow...
F1 = left dig tells you the stat of that channel (C for clear, S for
Scram, b for Baker) The right dig tells you about your data steam (O for
OK, E for error)
F2 = Tells you the address of the prom in the box (left dig tells you
what dig it's showing you 1 to 10, right address number)
There are some other ones... and if you reply back to me, and send me you
home address, I will be happy to put one in the mail for you.
