Hi Everyone!

As many of you may remember from last year, I got the Mini-RDS board and integrated it with the Vastelec transmitter.

(I started a How-To here: http://www.c3inet.com/FM%20Transmitter/index.htm)

I did it at the last minute and made the easiest cable I could for the connection to the PC which was the Unidirectional Printer Port cable (Only needs 1 680 Ohm resistor)

This year, I upgraded my show PC and could not get the printer port to work with the RDS board no matter what combonation of settings I chose in the BIOS for the port and within Windows device manager....

Since I am doing EVERYTHING else with serial ports (Even the LED Triks via the awesome TRIKS-C!), I decided to make the Bi-Directional Serial Port Cable (3 680 Ohm resistors, 1 1N4148 diode, and 2 5V1 Zener diodes) and get it back up and running.

To get it to work, you need to replace R9 on the RDS board with a 2k resistor.

Here is a link to the circuit diagram and a picture to interface the output of the Mini RDS to the Vastelec:

I'll post some pictures of radios with my station ID and messages in a few...

Here are 2 quick pics:

I'll post some more soon, but you can see how cool this is on the Zune!

As people tune in, they get song title and artist for each of my songs, as well as the Merry Christmas, Charity Info, & Donation Info on their radio screen as well as on the LED Triks (Different scripts and test files for now - Working on using the same ones...)

Great to hear KMC123!


Here's an odd duck for you.. I used your how to last year to test the miniRDS on the different Vastelec models.

I just noticed that R9 needs to be 2.2K, I use Serial and I've not had an issue yet. whats Odd is I never swapped out my R9..

Go figure.

Hey Steve - Are you doing Unidirectional or Bi-Directional serial?

The resistor swap is only needed for Bi-Directional...

I didn't do i right away, and afer making the new cable it worked at times and didn't at other times.

When checking all the docs / pages, one mentioned swapping both R8 and R9 with 2k resistors, and the other mentioned only R9...

I swapped out R9 first, and it seems to work perfectly now!

I use bi-directional Serial

I know I had a few issues originally and thought it was a bad chip, so i swapped it for my backup unit. they both work there is a low hum, barely detectable, I wrote that off as being too close to my computer power supply.

I'll swap out the resistor tomorrow and see if that fixes the hum.

Very nice posting and all. Which VastElect transmitter is this? I've got the FM02 so I'll need to find the connection info on the site again. I'm a little worried that since they changed the antennae connector on the one I've got, they may have changed other things as well.

Steve - I can't remember the model number, but I think it was the FM02 - it was the higher power model of the 2 Vastelec transmitters that were popular on e-Bay last year - can't seem to find this model / brand there now...

In case anyone wants to add yet another mod :) This one is buried in the data sheet, but is not implemented on the boards you buy...

I added a status LED to my RDS board between pin 1 and ground, with a 2.2k Ohm resistor.

It blinks +- once per second when on, and really fast / almost steady on when transmitting RDS data to the transmitter...

Finally found the Vast page again on the web. That actually looks like the FM01W due to the fact that it has a line and mic input. It appears to output 0.3 watts (my Chinese translating abilities are a little rusty). I believe it's a little better version that the FM01 or FM02.

Got this from http://www.vastelec.com/Products-04-11.htm

is the miniRDS still the option to stream text to the station as well ?


i just got a FM-02 and wondering if theres a way to add text via the FM....
Thanks

MiniRDS is the easiest way to add text.

This info is in the FM02 wiki:
