If you have an NCE system they are in the process of offering a Cab upgrade which improves the radio range and response times.

My understanding is this only affects the wireless aspects, so if you don't have wireless I don't think it will change anything.

Here is a link with more information:

It's a resistor soldered to the board. Seems that the wake up state of the keyboard does not allow the processor to reset properly, a single resistor soldered in the right place fixes it...

Found it on the NCE forum... there's a reference to a site and the site owner goes into a detailed discussion of why it happens... wish NCE would incorporate the change.

Thanks Greg! I've never had this problem in the 2.5 years I've had my NCE Cab. It's turned on every time and always connects to the base. I assume you'd had this happen? Does it just not turn on or turns on but does not connect to the base? How did you resolve the problem before the modification?

I only have the problem occasionally, but some of my friends have it more often. Reading the site, you see that since there are 4 contacts under the emergency stop switch, pressing on it from the side or top may make just 2 contacts close and avoid the problem.

My feeling is that it is a simple, inexpensive fix that has no downside. Hope it makes it into production soon.

The normal symptom is just not turning on.

If you have a situation where it turns on, but does not connect, that is a different problem. Normally resetting power to the command station clears that. If you have a power supply that "glitches" when it turns on, it can do this. I leave my system power on 7/24 so I rarely see this problem.

I have experience the problem Greg mentioned when the power system is first turned on and the cab will not connect.  Shuting the power off and then reboot then the cab comes up.  Something to do with the power supply.  Later RJD

Got my radio upgrade from NCE. Holy Smokes! The range is unbelievable. It used to be 40' beyond the base and commands rarely worked. With the upgrade I did a "Versizon" type test starting at 40' and moved further by 10' and sent a whistle command. Kept moving 10' at a time. I kept hearing the whistle blow. I ended up at 350' and it was still working!!!!! I still don't know what the range is because I haven't hit it yet. Wow!

Also, noticed better response on commands. For some functions before I noticed a delay, now it seems immediate for every function.

Wow thats good to hear. I'm still waiting on mine to be returned then I can send the second one to them. Maybe I could have skipped buying another repeater./DesktopModules/NTForums/themes/mls/emoticons/unsure.gif Later RJD

I'd like to hear your results when you get yours back.

Jim-

Glad to hear the fix is successful. I've got wireless cabs, but I tend to run them tethered for various reasons. Once mine are upgraded, I'll have to give wireless another try.

Best regards,
Bob

Hi Greg-

You wrote:
I'll be able to compare the mod and unmod units on next Saturday, will see how it works, because I have 3 base stations.

Do you have multiple radio base stations or multiple radio cabs? Or both? It would be interesting to hear more comparisons between the modded and unmodded versions. Everything I have heard has been positive.

Now, if NCE would only add a battery charging feature to the ProCab! (Zimo and Massoth allow cabs to charge when plugged into the bus. I believe there is a hack to add this functionality, but it would be nice to have this as a standard feature.)

Best regards,
Bob

Hi Bob...

Both, 3 base stations, multiple cabs wired and radio.

The only negative is that the extended hearing of the radio cabs can be a problem when you are at a show, where there are multiple layouts, your cab now hears a number of other systems, which COULD result in resduced response time.

I've thought about the rechargeable option. That would have to add a charging circuit to the unit, which could be problematic on space. My thinking is that the unit runs so long on batteries that having the possibility of picking one up and not being able to use it because of low batteries is not of interest to me.

If it "ate" batteries I would have a different opinion. You also realize that the AAA alkalines have much more amp hours than any AAA rechargeables you can get?

Those factors combined with keeping a few sets of 4 AAA'a at the ready and swap out in 40 seconds keeps me happy that they are not rechargeables.

Regards, GReg

My understanding is that if you use the new radio upgrade with some radio cabs that have not had the upgrade you should still see an improvement but not as great.

I'll test that also, but I believe that is incorrect, apparently only the receive function is changed in the throttle, not the transmit function. I'll let you know. We will be testing Saturday.

Hi Greg-

Did you get a chance to use the upgraded system? I am curious to hear your thoughts. Thanks!

Best regards,
Bob

Yep, astounding difference in range, and of course response time. It approximately doubled the range of the unit, and quickened the response time. The response time issue is because it is a bidirectional air interface, and your command is acknowledged and the display updated only after the command is received.

I will be converting them all.

Oh, had an unconverted one running at the same time as well as a wired one. No degradation of performance on any of the 3 throttles by using them together.

If the NCE shop is backed up there is another outfit in Florida that is authorized to do the work.
