Can anyone please tell me if it is possible to identify my RC9500 as a US or European model. The label in the battery compartment says RC9500/U1S.

The background is that I've just purchased this on eBay, upgrading from a RU950. To start with I've used pcfSwitcher to convert my config to run on the RC9500. I also use an LI910 RF extender as my equipment is in another room, but only IR commands are currently being recognised from my RC9500. My first thought is that I've bought a US version, hence my question.

Many thanks
Richard

I was not aware that the RC9500 had an EU equivalent. If your RF equipment cannot be controlled, then you have a US model that operates on 418MHz frequency. You might be able to purchase an RU model of the TSU7500 and swap out the RF transmitter.

The FAQ here lists the RC9500 as a single 'worldwide' model, but the user manual states that the RF comes in 2 variants (418 MHz and 434 MHz for US/EU resepctively).

Many thanks for your suggestion about swapping the RF board from another unit. I have a couple of broken RU950s and a RC5400 which could be potential doners.

Any idea if the transplant is possible and how to go about it?

My original querstion remains - is there any way to tell if I have a US or EU version of the RC9500 from the outside?

Many thanks
Richard

The label in the battery compartment of my Euro Spec RC9500 says RC9500/T1M so It looks like you definitely have the US spec unit.

Many thanks for the info.

Here's an update for anyone that may be able to advise further.

I'm managing to make the RC9500 work by RF if I'm in the same room and close (1-2m) to the receiver (Philips LI910), but not thru a wall. My RU950 continues to work fine.

Could this be some kind of side-band effect, given that my RC9500 may well be running at 418 MHz.

Or maybe I have a 434 MHz model, but the ouput power from the RC9500 is v. low for some reason (transmitter arial broken off?).

I'm wondering if I can confirm the RF carrier frequency by connecting the jack plug from the RF receiver to a scope or multimeter with frequency measurement capability?

Now that I've seen how good the display on the colour NGs can be, I really can't go back to the b&w version.

Thanks
Richard

Hi Richard,

First off have you made sure it is running the latest software/firmware? I found this at the Marantz US site

[Link: us.marantz.com]

Or on here in the files section

[Link: files.remotecentral.com]

I've always found the files on remotecentral to be the most up to date. Update the remote and then see how you get on.

Otherwise I had some luck using the PowerMid extenders for learning RF/sending IR and I wonder whether if you tried the "IR to RF" part of a PowerMid so that your remote sends IR to that part then translates it to 433 MHz and your Philips LI910 receives it as 433MHz and translates it back to IR. I know you then have the hassle of the PowerMid having to be in line of sight of your remote but could be worth a think.

I don't know enough about your other questions to help. Sorry.

Just found the RC9500 service manual for download, and this decodes the suffixes as follows
/N1M - EUROPE
/TIM - UK
/A1M - AUS
/U1S - US

So it does appear that I have a US model , and therefore need a US RF receiver (RX7001 or RFX6500). Oh well, back to eBay.

Thanks all for your comments.
