I'm using an OLIVETTI 486 @ 60MHz for all DOS based RSS without any problems yet. (some times I have to lower the speed thru BIOS).
After programming the MSF. I get this sequence:
1. All TTRC leds on, then "disable" led on. display "---"
2. "TTRC Encode" goes off, display "4.07"
3. "Fail Soft" goes off, display a short "---" then display "d.A.O."
4. All TTRC leds on, "disable" off. display off.
and all over again...
SSCB VER 4, TTRC VER 5.
Looking in an error code list I got that I have a bad codeplug in the TTRC.
I swiched the PC to low speed but I had some comm problems.
I know very little about MSFs, so, any ideas?
Also, since it was a repeater and now a base station I removed the duplexer and installed an antenna relay, but to connect it where? (I mean the relay power)

Re: MSF programming problem
The antenna relay has a two-pin connector on it. It plugs into a cable that's probably missing in your station. The cable runs down the right side of the station to the Interconnect Board under the RF Tray, where it terminates in a three-pin connector that plugs into J500, located on the right side (looking from the front of the station) of that board, hidden by the TX VCO casting of the RF Tray. If you slide the RF Tray out and look underneath the right side behind the cable bundle, you'll see a two-pin and a three-pin connector on the rear of the Interconnect Board that hangs down under the RF Tray. (The two-pin connector provides power and ground to an external reference oscillator for 800 and 896 MHz stations; ignore this.) The three pins have the following signals (top to bottom):
3: Aux +13.8VDC (A++)
2: +9.6VDC
1: Antenna Relay
The antenna relay cable connects to pins 1 and 3 only. A transistor on the SSCB grounds pin 1 to activate the antenna relay. There is a protection diode from that signal to Aux +13.8VDC so you don't need one on the relay.

Computer speed is rarely an issue with the MSF5000. I use a Pentium 3 at 850 MHz with no problems. About all you can do is keep trying to write the code plug to the station. If that doesn't fix it, the EEPROM inside the TTRC's microprocesssor could be defective, and the only fix is to replace the IC or the entire board. You could disable the TTRC in the code plug but then you wouldn't be able to use it.

Re: MSF programming problem
Hi Bob, thank you very much for your detailed information.
I tried several times to re-program my MSF, but in vain.
And since the problem persists, I must think of the eeprom, so I'll try to replace the mcu.
My TTRC board is much different from the one in the repeater builder photo-tour.
It is single-floor with the two MF10 hybrids and no transformers at all (weird for a TRC).
It is also missing a socketed 8-pin chip like the potos.
I also tried to disable the TTRC, but the problem is here to stay. Error d9A
(I kept the original codeplug to be in the safe side, since I don't know how to re-enable the TTRC)
I this helps. it was operating ok at arrival.

Re: MSF programming problem
Once you disable the TTRC in the code plug, all of the TTRC info is removed from it. The only way to re-enable the TTRC is to build up a new code plug from scratch starting with one of the default code plugs.
I would think that even if the TTRC looks different, it still programs the same way, but perhaps there's a special version of the software that matches the station you have. European models could be different.

Re: MSF programming problem
You also have to move jumpers around on the SSCB to take it out of the HSR data ring. I THINK it's JU1 and JU5 moved to alternate but don't hold me to that (I'm at work, manual is at the house.)Paul wrote:I also tried to disable the TTRC, but the problem is here to stay. Error d9A

Re: MSF programming problem
Confirmed with the manual:
JU1 - TTRC HSR - Alternate position for no TTRC present.
JU5 - Trunking modulation audio - Alternate position for no TTRC present
Those are the only two you need to move. After that the D9A error should go away.
