Hi to all.

I need a pinout for AUDIOVOX 8500.

I already searched for and checked the ensemble different pinouts, but has not found anyone correct.

Please, help me!

The pinout belongs to audiovox CDM-135 but it's the same for CDM-8300 / 8500 / 8600 this is not tested yet...

If you have the schematic to make the cable plese post or send to me. my email is ramirohn@yahoo.com.

I hope it works for you and don't forget to post if works and send me the schematics.

Best Regards from Peru, and sorry for my english.

For Audiovox 8500

##2773 - Debug - Field test mode.
Rx = Receive power measured in dB.
Tx = Send power measured in dB.
P_Rev Protocol Revision = 6 is 1x, 4 is regular CDMA.
Ec = A measure of how strong individual connections from the tower are compared to everything that the tower is transmitting. Compares the pilot signal to the overall level of traffic, but this is a good indicator of how your connection compares to the overall level of traffic from the tower. -3 dB to -8 dB is usually a “good” Ec. When Ec gets larger, like -10 dB or -15 dB phones will start having trouble maintaining their connections, even with full signal. C = Channel. B side carriers start on 384. Will increase by 1.25MHz or 41 channels.

##7738 - Change P_Rev. Allows you to force CDMA (Select Rev 4)
##2283 - Set the data port baud rate
##2240 - S/W test
##2250 - RFNV Contents. Tons of options here. I have no idea what they do.
##1111 - EFS space (This doesn't seem to work on the 8900. The screen loses resolution and freezes)
##2222 - RF stuff displayS CDMA Automatic Gain Control and Low Noise Amplifier data
##1122 - Test ringtone, vibrate, and colors. Adjust contrast and stuff.
##1133 - Be careful! Resets the phone back to factory settings.
##1144 - Change the length of the keypad tones. Navigation keys don't work here, use the numbers to change values.

#7623 (#ROAD) Roadside assistance. I'm not sure what they do, but I'm sure it will cost you.
#5625* (#LOCK*) Unlocks keypad and tells you the code (very useful for sure)

##2769737 (##BROWSER) Internet Options. This is where you can change uplink IP port
##27732726 - Software tests and stuff. Displays the date/time of firmware. Lots of cool stuff in here.
##27752345 - Battery info and modification. Be careful!

2539** - Changes authentication key. This is the A-Key or Authentication Key. Don't mess with it!

**1004 DM Mode Enable (harmless but I'm unsure what it does, maybe don't try just in case)
**1005 DS Mode Enable (same as above)

well after all the pinouts posted below is works fine, I made my own cable and everything go perfectly.

Congratulations!

Merry Cristmas !
Does this cable require an IC chip (from ttl to rs232..like max 232? )
or...may I ust cut off the end of my 8500 usb cable and place db 9 ?
Thank You !!!!!!

Hi, you can made this cable incluiding a MAX232 or without it, but always is necesary a couple of diodes, resistors and other components. do a search and you'll find the schematics to made the cable including IC and without it, almost all the schematics are the same only have to change the phone pins

I recommend that buy a cheap car charger so you can get the phone plug and don't need cut your cable. but if you have an USB cable, why you need another with a serial connection?. :confused:

I hope that this will help you.

Yes, and thank you friend...I am needing a serial connection to work with the Audiovox Flash programs and BitPim...I jus have a pure USB, no serial.
Merry cristmas!

orangetest_999 : Can you please post USB pinouts for Avox 8500 in this thread? :)
Also pls tell what programs you currently use with USB link?

I have two interface but already use both and with any it synchronizes me the audiovox 8300
1a interface is with + the use for the to-505 and it works
2a interface without + alone it is rx tx gnd but it doesn't synchronize the audiovox 8300
that interface is the one that I have to use?
I am using denso pst but, only this in green the pc and cellular and blinks of red on the cable
the pinout that I post ramiroquay arm I am made the but correct for this model one but not you in I am mistaken
if I achieve sincrinozar I warn them
greetings and thank you for their support ahead of time

I inform that it is already able to synchronize the cellular one with the dense pst but
n script I cannot write esn
i need your help to script
I am working with:
mode offline-d (successful)
spc "123456" (unlocked)
nv_write esn {0x12345678} (comand failed)
I can read the cellular one but I cannot write new esn helps me if I am I aquivocado with script
with qxdm reads it but it sends desconeccion errors and coneccion alternately per second
thanks

sorry but english its very bad
but I attempt you improve it greetings to all

Alex76, dime que problema tienes talves pueda ayudarte? dices que tienes 2 cables uno con VCC(+) y otro sin, te cuento que yo hice mi primer cable y no funciono sin vcc asi que es recomendable que le pongas la alimentacion. y si deseas cambiarle la serie al 8300 u 8500 seria mejor que uses el UNICDMA 0.98 como no tiene para audiovox lo uses en qualcomm. la verdad no he probado con estos modelos pero en lineas generales debe funcionar ya que a mi me ha funcionado para muchos otros.

Saludos.

gracias por el dato ramiroquiay
correctanmente solucione el probrema de la interface con una con vcc el problema era que estaba utilizando el denso`pst pero no me cambiaba la esn pero baje otro programa para audiovox 1100 y con ese pude cambiar la esn de antemano te agradesco el apoyo estoy a tus ordenes
saludos a todos

thank you for the fact ramiroquiay
correctanmente solves the probrem of the interface with one with vcc the problem it was that it was using the denso`pst but it didn't change me the esn but lower another t programs for audiovox 1100 and with that I could change the esn ahead of time you agradesco the support is to your you order
greetings to all
