RF 602 help please????

I bought 'em and blowed if I can make 'em work!
I have a km/2000 and a pentax af200t flash and a Starblitz 250baz flash........
Both flashes work fine on camera........only in manual tho.......

these are the triggers I bought......RF-602 RF602 For Canon 500D/450D/300D/350D w/2 Receiver - eBay Other Equipment, Lighting, Studio Equipment, Photographic Accessories, Cameras. (end time 09-Mar-10 20:18:47 AEDST)

Are they the wrong ones?

I cant even get a test flash when they are mounted on the recievers. The light wont stay green .
I have changed all the batteries for new ones, changed the channels, just about stood on my head and pleaded.........

any ideas on what might be wrong anyone??

cheers

the light staying green thing was mentioned in the main rf602 thread...set you shutter speed to 1/125 to avoid the black band.
Don't go over 1/180 for shutter speed too.

shutter speed low enough?
If you press the transmitter's fire button, does it trigger the flash on the receiver?

shutter speed down well below 125........nothing
if I push the trigger on the transmitter the light on the reciever goes green and then red when I push all the way. Take my finger off and it continues to flash red........

So the receiver led changes color when you press the test button on the TX, but the flash doesn't fire?
Neither flash fires?
I've never seen this happen...sounds like you got a bum set...

Some flashes do this as they don't use the center pin to trigger the flash. If your flashes are like that, then they won't work with any triggers.

Thank you

A flash with just the single center pin is not one of these flashes. For it, I would verify the voltage. Do you have anything in the area using the 2.4Ghz frequency? Did you try changing the pins to another channel?

The normal use indicator is that the red led flashes on the receiver when on and waiting for signal. With the transmitter off the camera, the transmitter led does nothing until the top button is pressed half way. At half press the led turns solid green on the transmitter and the receiver. Once the button is fully depressed both the leds on the transmitter and receiver turn red. Is this what you are seeing? The flash doesn't need to be mounted for this test.


Thank you
Russell

yes that is what I see..........
I cant imagine there is anything in that frequency around, I took them into work and they wouldnt work there either.
Once I mount the flashes........I cant even get a test flsh from them........
The flashes should come in under 10v but I will borrow a multi metre today and check.

I'm out of suggestions at this point. I would think there is something wrong with them if the voltage on the flash isn't the issue. Sorry I can't help further.

Thank you

Use the bundled mini jack cable and try if receiver fires your camera.

1. If it trigger just when you plug the jack in camera set the camera in burst mode. If it repeatedly fires without you holding the transmitter button than you have short contact between the center pin and shoe on the receiver.

2. If it doesn't trigger the camera at all than you have no contact at all.

He is using a K-M/2000. The camera doesn't have a remote shutter port.

Thank you

Ok then, try the hot shoe and center pin on receiver with multimeter. There should be contact only when you fully press the transmitter.
