2 join 2 Tait TM8100 Radios to make a temporary repeater a cable is required

Dear colleagues, I am working out in Mali, West Africa and there is NO Tait support whatsoever. In fact no-one has even heard of Tait.

My Tait Repeater model TB8100 has decided it cannot communicate with its power module and power amp and has closed down. I have 2 brand new TM8100 mobile radios which I could use a a repeater; Tait produce a lead specifically for this TMAA04-06. Basically this lead connects the 15 pin-D Auxiliary ports together. There is the addittion of a RJ45 GPS connection and an External Interface connector but its the Auxiliary to Auxilliary pinout schematic I require plus the connections and values of any pull-up resistors, links etc.
The Auxiliary to Auxiliary leads only use 9 of the available 15 pins, I have the pin identifier from the TMAA04-06 Datasheet but not the interconnections - can anyone help?

Thanks for the offer Morti, Tait have emailed me all the manuals and some schematics as well as the latest software for all my 8100 series kit (TB, TM and TP)
I have figured the interconnections out easily enough… just need to find 15 Pin DB Male plugs in Bamako, Mali. No luck so far.

If you wonder what I am doing here, I work for the EU as Communications and IT specialist in the EU capacity building mission.

Hi, I have uploaded a pdf excerpt from the TAIT TM8100 Service manual with the Cross Band Repeater cable connections plus my quick-dirty working example.
Check Manuals/Tait or search by my callsign as contributor.
Happy to be of help.

Hi there.

First of all - I am not a ham, but I am communications leader for the Luster SAR Group in the Norwegian Red Cross. We use TETRA and analog VHF systems.

I have a similar case as you did. I have got my hands on some TM8110 mobile radios, which I want to put together as a repeater, and if possible, a third radio as link radio - to link this repeater on channel A to another repeater within range on channel B. Not sure if the last case is possible…
But to start, I am looking for the same thing as you did, but I cannot seem to find your example of interconnections for the TMAA04-06. Can you point me in the right direction?

Thanks!

Hi

The description for a cross band & back to back repeater is in Tait Technical Note TN-887-AN "TM8100 Cross Band Operation" dated 28th June 2004.

Copy could be found here at time of posting http://manuals.repeater-builder.com/2006/TECHNOTE/TN-887-AN_TM8100_Audio_Linking.pdf

This is for a radio to radio connection and has cabling & software settings descibed for a back to back solution. - For a in-band repeater just omit one direction.

It may be possible to construct additional cabling to create the connection you describe.
