As the title says, i need the pinout info / schematic for the rear control head cable on the Syntor X9000.

I'm going to take a shot at building one but i can't find any info on it. Mike B's website has all the other cables for the X9000 but no mention of the rear cable.

May take me a day or two, but I have one here I can ring out for you. If noone beats me to it, I'll post it when I ring it out.

Thanks!

If you do that i'm going to also forward the info to Mike B so he can put it up on his website. Of course i will make sure you get the credit for it.

I'm surprised that the rear head cable is so unknown yet. One other question that you might be able to answer then. What is commonly used for heads on the dual head setup? I did some searching and it sounds like a 1071 or 1073 can be used for the rear, but can a regular 1033 still be used for the front head?

Scott, I thought about this after I replied to your post earlier today. We are both trying to make this way more complicated than it really is. The pinout of a regular cable should be more or less the same as the rear cable. The only difference I know would exist is the absence of the 'orange and green' wires at the head end of the rear cable. See what happens when you try to over-complicate things?:lol:

As for what head can be used for the front head in a dual head setup, it doesn't really matter, as long as it is compatible with the radio in question to begin with (and isn't a 1071, of course). The only thing that should matter is the rear head be correct. The 1073 you mentioned is not a rear control head. The 1071 would be the correct head to use. However, you should be able to convert almost any Systems9000 head (that is normally compatible with an X9000) into a rear control head by using the bit-bang feature in the Spectra Lab RSS. This would not work for the heads which store the firmware in U1 (µprocessor). If you need it, I've got a dump of the related bits for a 1071.

I was just thinking about that myself tonight, obviously the rear head would need the same connections to communicate that the front one does. And i read some other posts about no orange or green wires on the rear control head cable.

So, lets get into this head conversion issue. Which heads would i not be able to convert then? I thought all of them have the firmware in U1?

Also, are you saying you can run Spectra Lab on the X9000 with the control head you want to convert connected to make the changes? Otherwise i don't have a Spectra to put the head on to do any trickery with it.

I might be able to get a 1071, that is if i can find one, but at this point i would think i'm better off knowing how to convert another head.

I noticed on Mike's site he mentions that a 1071 could be converted to a 1073 equivalent, so i figured if that could be done maybe a 1073 could go the other way and become a 1071.

HCN1062 (permanantly 2k), HCN1063, HCN1066, HCN1068, HCN1069, HCN1071, HCN1073, HCN1076, HCN1078, and HCN1121 all contain the firmware in U0007, not the µprocessor. I was, however, slightly mistaken. U0007 is not the EEPROM that the codeplug is in, but rather a PROM specificially for the firmware. So, it may be that any head that is compatible with the X9000 in the first place can be bit-banged into a 1071. I'm almost positive that the 1073 can be 'converted'.

As for how to bit-bang it, yes, you can simply connect it to an X9000, and fire up the Spectra Lab RSS to do the hacking. I have already done this to convert a head that was originally trunking, and didn't play well with the X9000 anyway, into a conventional X9000 head. I don't recall the model of the head anymore, but it was one that Mike used to have posted as "Looking for control head information". He had never tried 'reseting' that particular model head, and I wound up with one. He sent me the proper bits to change, I changed them , and it worked. The moral of that little story, I don't have a Spectra, either .

BTW, did you want me to send you the dump of the 1071 bits?

Ok, so basically any SMD head is a candidate for a rear control head then since the firmware is stored seperately.

Send me the info, you got me all intrigued now! I know i can get a hold of a 1073 easier than a 1071 to try this.

Also, if you happen to find any documentation on a HCN1067 let me know. I should have one in my possession soon and then i will see what i can do with it. If it's an SMD head maybe it can be converted to a rear head also.

You've got a point there, Scott. I didn't notice that all the heads listed as having the firmware in U0007 are SMD, but they are. In that case, yes, any SMD head should be convertable, with the possible exception of the 1062. I'm sure, but I think the rear head has to be 8k, and the 1062 is permanently limited to 2k.

If documentation for the 1067 isn't on Mike's website, I can't help you with it. I don't have access to any other info on these radios. All that I know about them I've learned from lots of reading on his site, and personal experiance with my own X9000s.

Seems the 1067 is a big mystery then, well maybe i can be the first to document info from it then.

When the info from you get's here i will take a look at it and see what i can do. I do know where i can one or two of the SMD models to try it on. Should be interesting to see what ones it will work with.

OK, Scott, I've just sent the information your way.
