Hello,
I am looking for information on interfacing an MSF5000 to a community repeater panel. I know that there was a kit that Zetron offered to interface their panels to the jack on top of the MSF's control tray.

Any information and/or documentation would be greatly appreciated.

Cheers...

Lots of MSF5000 specific info can be found here:

We were the ones that did the original interfacing for the M38 tone panels to the MSF5000 repeaters, with Zetron's help. Zetron making the final design.
This replaced the Motorola Community Tone panel that was a b*%$^ to program.

I doubt anyone at Zetron remembers this interface. Motorola was NOT happy with us. But our repeaters worked..

Thank you for the info. At this point in time, I am looking for any documentation or information on the interface module itself. Any help will be greatly appreciated by not only myself, but many others.
Cheers...

Everything plugged into the same connector used for the test set on the MSF5000.
The Zetron M 38 put out a logic level when the correct PL was decoded. The interface had some logic that translated it on to the MSF5000's BUSS in the in the correct time slot for PL Indicate. The generated PL tone was fed thru a resistor isolation into the modulation input, power, discriminator audio, and GND went to the Zetron from the same connector.

Here is a post that I posted a little while ago while screwing around with the MSF5000. Some pins that you might need are listed, including the COS pin with info.
Hope this helps, Rob

Here is the info that I have so far from linking a Cat 300dx controller to a UHF MSF5000 CXB model repeater.

Some of the info is already posted in another thread, so this would be the updated info as I have changed some things around.

Here is the pin outs for the J2 connetor located on the side of the repeater.
Most of these connections go the the TTRC board (I believe)

PTT- Pin 12 on the J2

COS- Pin 23 on the J2 "RDSTAT" will appear as RX1ACT on the test panel and mux bus diagnostics in the software. Originally I tried taking this from pin 1 of U1552 but for a regular controller this just provided a signal when the radio rx'd any signal on channel (which equates to no pl control) This is the pin you would use if you are using a "community deck" type panel where it will rx and tx it own pl/dpl.
** If I remember correctly the COS output provides an active low signal which I believe shows 5-6 volts DC and when the radio rx's a carrier with proper Pl/dpl it will drop to almost zero. Most controllers are selectable to some degree of which logic they will accept active high or low.

Audio from reciever- (Line 2) +++ Pin 2 on J2
(Line 2) ----- Pin 3 on J2

Audio to Transmitter- (Line 1) +++ Pin 6 on J2
(Line 2) ----- Pin 7 on J2

Audio Ground- Pin 17 on J2** Tie together pins 17-3-7

Logic Ground- Pin 19 on J2 (Ground for controller)

Repeater programming- In the software all "repeater controls" have to be set up as a base station operation " Half duplex" operation with ptt priority to the wire line.

- Set the "System Connector" to line and the "Spare output" to active low. This is in the advanced information section on page 8.

- Ideally the MSF will be functioning as a base station, so you would just program you channel info and pl info for what you need.

- All of the audio/dev/tonal quality adjustments can be adjusted with the softpots in the service area.

******** It is also noteworthy to mention that we found that the controller audion was not behaving properly because the controller didn't pose a large enough "load" on the Line 2 audio side. So we ran 2 1200 ohm (=600 ohm) resistors across the screw terminals of Line 2 +/- just below the J2 connector. This gave line 2 audio the 600 ohm load it would normally be looking for with a deskset tone remote type set up-*****

I hope this info helps you out. I am not an expert on this at all. Please test properly all of the connections before connecting to them. I also hope more people add to this post

The Zetron 38A manual is available for free download on Repeater Builder. It contains an exact step-by-step set of instructions and a diagram for interfacing a Zetron panel to a CXB MSF5000 control shelf. From that you can extrapolate the needed connections for most any external repeater controller imaginable.
