heres a quick question without burning up my radio trying it

Can you run 2 T-Connectors + plus the original control cable on a syntor 9000?

I want to use a T-Connector for Pac-RT and The T-connector for the Siren

Any ideas?

Thanks

Yes you can do that, they even made an extra long 3 cable hold down screw for it.

Another vote for yes...

I had one through here a while back that had three T-connectors on it! Siren, external options housing that had a DTMF and i think MDC boards in it, and a Pac-RT.

Just go to the hardware store and bring the screw from you existing cable with to match the thread. I don't remember what the size was now but i bet Jason or someone else can say what it was exactly. I found one at a True Value that was the right size and they had them availble from 1/2 inch to something like 8 inches in length and came in either philips or hex head. The one i used had a allen head on it and was plenty long so i had to cut it to length. If you have to cut to length get a nut to match and spin that on, then cut it off and spin the nut off to clean up any burs left on the end.

Don't forget to include a washer in the length needed, you will want to put a washer under the bolt head to keep it from damaging the plastic shell on the connector.

They aren't available from Moto anymore as far as i know, but then i haven't checked the part numbers lately.

Actually there is a bit better of a way than that.

You should be able to chain the cables and T connectors so that your siren is first, then the assy box is next followed by the PAC-RT. All of the appropriate leads should be cut through.

Check the manuals to see what's in each cable but you should be okay.

I don't immediatly recall the size of the bolt either, but I do recall that it is metric.

(the Syntor X 9000 NKN6371A Cable)

As for daisy chaining the cables. The PAC-RT cable T-connector pin 32 (B-) ground is missing in the Siren/PA cable. The PAC-RT cable T-connector pin 6 should work because the Siren/PA cable jumpers pins 6 and 7 together. You can check the Siren/PA schematic and see if the circuit board provides a ground connection to pin 32. If it does not, you can fix it by moving the PAC-RT cable T-connector pin 32 to pin 8. If there is enough slack in the wire you might be able to physically swap the pins inside the T-connector housing.

Of course it is assumed you are using a standard negative ground power system.

The problem is pin 24 (Spare 1) is missing from the Siren/PA cable. Spare 1 is used to connect the Systems 9000 control head (modification required) to the PAC-RT microphone PTT input. This allows PAC-RT users to hear anything transmitted directly from the mobile using the mobile microphone. Daisy chaining the two cables will not support this listening function.

I looked for the 3 deep extended connector knob part number a long time ago. I was never able to verify the part number I did find, so I never included it in the web site. I do remember Motorola wanted around $ 80 for it. I know they were used on the primary radio of a Systems 9000 dual radio (not the HHCH dual radio) that also has a Siren/PA. This required the Siren/PA T-connector cable and secondary radio T-connector cable to be stacked together with the control head cable on the primary radio connector.

The answer is yes, you can run 2 T-Connectors + plus the original control cable on a Syntor 9000. Motorola did it.

Actually, regarding the stacking of connectors on a dual radio X9000, non HHCH, the manual I have shows the chaining of cables, not stacking them.

Without pulling the manual and looking, the diagram shows, as memory serves, the secondary radio is closest to the control cable, then the primary radio, then the siren.

This was because of the audio feed from the primary radio to the siren for external radio functionality.
