P7100 doesn't RX analog or unencrypted P25C traffic when keyloaded?

[merlin]

My original notion was a box the RS232 plugged into. This had the switch and resistors for the various programming modes. A universal programming interface if you will. from there the cable would go to the UDC connector.
Point here is the resistors don't have to be at the UDC.
Well, the finish is this ugly snurd for the UDC and a toggle switch protruding from the glob.
It works, so that was where I left it.
(Anyone asks, 'I didn't do that' )

Have a picture of it?

Is this for Provoice or Aegis? The help menu shows that key banks are only used in those modes. For P25 trunked or P25 conventional, I don't think you'll be prompted for key banks.

That's what's odd. I'm only assigning AES keys to P25C systems, but this radio keeps wanting key banks and doesn't go into KEYLOAD IDLE even when you do assign key banks and DES keys to a conventional system, set for encrypted ProVoice.

It must have never had key loading fully implemented in it's design.

 

[TDR-94]

I can assign all 8 key banks and the radio will toggle through KEY LOAD BANK=1, BANK=2, BANK=3 etc... when using the arrow keys on the radio keypad. Pushing any other buttons just results in an error boop tone.

 

[rescue161]

My P7100 does not give me access to key banks at all. I assigned the P25 Conv tab to use encryption and then select which algorithm. Then when I connect the cable and select keyload (on my cable), it shows KEY LOAD IDLE and then I push the key to the radio with Key Loader.

Unless you haven't done so already, try setting a value of 1-8 in the max key banks setting, in the Digital Voice menu section in RPM.

I tried creating a conventional system, then assigning a key in the conventional set, under voice options and then selecting ProVoice, encrypted, and a key bank in the convention system tab. This radio still didn't do anything different even though all the parameters for assigning a key bank were set and the key loader had DES keys created to match the same key bank and key ID.

 

[rescue161]

I make a P25 Conventional system. Then I go under that tab and create a P25 Conv Freq Set and set each channel that I want to be encrypted to P25. Then under the P25 Conv tab, I select either AES or DES and set my key number. That is it. If you are trying to create a ProVoice channel, then I can't help with that as I haven't messed with ProVoice in a long time. As far as I know, the key banks don't have anything to do with P25 conv or P25 Trunking.

This is correct. I've never had to do anything special in RPM1/2 to get a key loaded other than specify the default system key, or strap the key to a talkgroup.

 

[TDR-94]

Yes, key banks are not related to P25, only Provoice EDACS and conventional systems set for Provoice or AEGIS.

"This particular" engineering prototype P7100 only indicates NO KBANK ERROR = 0871 or KEY LOAD BANK = 1-8, when powering it up with a cable configured for key loading. My only interest was configuring the programming cable into a key load cable and loading AES keys into the radio, with the key loader, for a P25 system programmed into the radio, to verify if the radio receives unencrypted P25C transmissions when set to private mode. The P7100 user manual indicates that it does not receive digital unencrypted transmissions, when set for private operation, only analog and encrypted transmissions are received.

This P7100 does not key load regardless of what type of encryption settings are assigned or what system is being programmed or what version of Firmware or DSP is loaded into it. I was just configuring it to have the ability to assign keys to a key bank, since that is what the radio keeps indicating when a key load cable is attached. The key loader can't talk to it, regardless.

Being that it is a engineering prototype, I think it's just spewing out error codes and is in fact, not able to have any keys loaded into it with the key load cable or the key load software.

My P7100 is also one of the full 40 optioned prototypes and it works fine. You have to delete that Provoice/conventional system and create only a P25 Conv system. Then it won't give you that error. Once you start trying to create a Provoice system, the radio is getting confused. Follow the steps above and it will work.

I only created the ProVoice conventional system to see it the radio would actually key load if configured to use DES keys and key banks. Originally, I only had the P25C systems programmed to use AES keys and no conventional systems, ProVoice, DES keys or key banks were assigned.

It gives the NO KBANK ERROR=0871 and then bonks out to the power-up system when the key load cable is attached, if there is NO max key banks value assigned in the digital voice options. It won't even go into KEY LOAD BANK = 1-8 if you don't assign a max key bank value in RPM.

 

[TDR-94]

I can load keys just fine into the P7200's even with the modified programming cable. They will actually go straight to KEY IDLE if the cable is attached after the radios are turned on. It's not a good idea or recommended to do it that way, but it proves that they go into key load mode with the cable modified as a key load cable.

I also tried connecting the cable to a 700P, which doesn't support encryption options, and it correctly displayed NO PVT.

You can send me you pers file and I'll set it up the way mine is. Then it should keyload properly. Are you using RPM14?

I have the personality set up properly, the radio is just incapable of going into KEY IDLE. This radio also never had the driver for the TX/RX LED's. It also can not transmit modulated audio, unless a speaker mic is attached. The main board has also had "engineering"rework done on it. It's not a standard factory production main board.

Who knows what the engineers were testing.

 

[TDR-94]

I even dumbed down the personality to a single P25C channel. TEST1 136.0000 MHz.

 

[rescue161]

I guess you got a dud then. Like I said, mine is a development 40 option radio and it works 100%.

As far as no audio, I bet that you are missing the small jumper that carries the audio from the board. They are easily lost when you take the radio apart. One of mine fell out and I lost the ability to transmit audio, but once I located the jumper and put it back in place, it worked like a champ.

This one has the little sandwich looking connector piece that connects the front mic to the display board. If that's the jumper you are referring too.The main board on this also has some jumper wires.

 

[rescue161]

Yes, the little sandwich piece is the one to which I was referring. I have seen them where they don't quite line up and cause your issue. Other times, they are just missing. If I remember right, there is one for the display and one for the mic. I think the 7200 has the same thing, but it has been a while since I had them apart.

 

[TDR-94]

Yeah, when I re-housed this radio, with new housings, I double checked those connections to make sure the new "zebra" strip connectors were all in place and not missing. They can easily get dislodged or stuck in the old housing.

This radio recieves just fine and all the other functions have been working without issue. I never had a chance, up until now, to key load it. So I didn't know that was going to be an issue.
