Jaguar RU vs. 7100IP: Same PC board or not?

[ElroyJetson]

I've noted that if you have an RU series Jaguar, it can be turned into a 7100 via the maintenance tools. And this seems to work just fine.

But....is there actually any difference in the main board between an RU board and a 7100 board? (Same band, of course...)


Specifically, the 7100 (and 5100) have the red/green TX/BUSY LED to drive. The RU 700
doesn't have to drive that LED as it's not part of a 700. So will an RU board, if programmed
as a 7100, and if it's given the CORRECT display board, case, and other parts that make
the radio physically different, (including the frame), will it drive the red/green LED?

Sometimes I get the distinct impression that I'm technically "deeper into" these radios than most anybody else who's a regular visitor. :/


But maybe there's someone out there who can teach me...?


I'm learning a lot in a hurry. Now that I'm getting the service manuals and studying them,
with radios to fix, I'm learning a lot. Before long I may be able to answer tech questions
on these radios rather than have to ask them.

You must be able to get your mitts on the new stuff easier than some of us
Maybe things will get better after rebanding is done--(If it ever is) All the "experts" around here are VERY busy lately

 

[wiliki46]

Unfortunately I do not think that Mark Cobbledick looks at this forum. He would be the most helpful person for tech questions.

 

[ElroyJetson]

Rebanding is an opportunity to make some money. If you can handle reprogramming
a bunch of radios in the field, contact your local 800 MHz radio system contractor and
offer your services to them for when it comes time for them to reprogram ALL their
radios as fast as humanly possible. I'm sure that they'll be interested in getting some
help. 12,000 radios take some manpower to reprogram even under the BEST of circumstances!

So far all they want me to do is shuttle police cars between the shop and precincts; I think they are afraid I will load RPM into my own laptop--Even tho I heard it has to be verified over the net from MA\Com. (Is that true?)
Since being a hostler doesn't turn me on and I am too old to want to work more than 4hrs a day, I am just going to watch from afar

Version 19 is where M/A-Com started licensing ProGrammer. If you already have 19 or 20, you can load RPM without having to get a new license.

I have been told that the 7100 is a faster processing radio. I do know that the 700's and early 7100's were made in Japan by Kyocera, and the later 7100's were made in in Ireland (unknown company). The mfg's. may have used a little different setup , but still keeping in M/A-Com's design.

I am sure that you have figured out that everything M/A Com is contracted out.

 

[ElroyJetson]

Kyocera? I was figuring JRC, which DID make a lot of their other earlier models.

I had figured out that M/A-Com probably actually builds little equipment but has most of
it made by contractors.

Heck, Motorola does that too, sort of. But Motorola does build a large portion of their
equipment in their own factories.

Elroy

not to sound like an ass but then why are you asking them?

anyhow, I am pretty sure they are the same board, but why does it really matter? you really shouldent be mixing such things in a real enviornment...

in addition, i am pretty sure JRC was renamed NJR recently no?

 

[ElroyJetson]

Actually the boards are somewhat different. The differences are to support certain features that a Jaguar doesn't have but a 7100IP does. Like the red/green TX/BUSY LED,
for one.

Knowing that, I wouldn't be mixing models and boards, either.

The LPE, Jag 700p, Jag 725M, P7100/5100 and M7100 all use the same microprocessor, the Hillary chip. The DSP chips and memory have changed through development. All these radios are 100% DSP driven. With the early LPE radios they had 512k memory and used the C50 DSP chip which would do Aegis (DSP codes beginning with a "H" or a "K").
The LPE's were given the C56 DSP chip to enable provoice and then shorly after bumped up to 1 meg memory and use DSP codes starting with an "I" or "J".

Then it became the short lived 700p KRD model. It also used the C56 DSP and 1 Meg memory. Didn't improve on capabilities but it sure is a lot more stout.

Next came the 700p "RU" with the new C5416 DSP chip and 2 meg of memory. Now it had P25 conventional and EDACS IP capability. Also came the J725M mobile version.

Until now these were only available in 800 MHz aside from the 900 MHz LPE's/Prisms. The first generation P7100 for 800 MHz used an I & Q modulator in the transmitter as did the 700p "RU" (and use the "G" series DSP codes). The J725M and the M7100 use direct FM (the "F" series DSP codes). It is the P7100 "I & Q" main board that is the same as that of the 700p RU. Except for one tiny thing. The P7100 uses a different keypad board than the 700p and the front panel mic on the P7100 gets it bias voltage from the keypad board. The 700p RU gets its mic bias from the main board. You can take a P7100 board, install the bias resistor in its place and the board works perfect. Setting a 700p RU to a P7100 in radio maintenance doesn't buy you anything, the capabilities of the radios are the same.

The P5100, as well as VHF, UHF and current 800MHz P7100 radios all have direct FM. Though never used in the 700p, the spot is still available for the mic bias resistor and once installed you have a direct FM 700p.

 

[ElroyJetson]

That's all been noted, of course. Good stuff to know!

Tell me, is there a definitive way to differentiate between a direct FM version and an IQ version of the 7100's main board?

Mask number, perhaps? (Number in the solder mask, easily readable, unique for each
major version of the radio.)

In addition to the LED function the 700 will not support Command Mute unless it is a RU version.

 

[ElroyJetson]

OK....but what IS Command Mute, anyway?

I have a true 7100IP that has option 38 in it, which I gather is some form of text messaging,
but haven't seen where to enable it in the software. The radio isn't an engineer's special,
either. It has a real, customer-ordered feature package...and a nice one at that!

[otter9309]

Command mute is for the user to place the radio in a quiet state while waiting for an I-call. Fire and EMS will use this feature to avoid hearing all the active dispatch traffic. This is a must at night when units are trying to get a little rest. A key is programmed to mute the radio, and when the I-call is received the radio rings and opens to dispatch traffic. High ranking officers in PD also will use the feature if they need to be alerted to special traffic.

Programmer states the radios support this feature all the way back to the M-RK, but this not the case. M/A Com is aware of the issue, but does not want to spend anytime updating code for the KRD.
