Colin Naylar Posted January 24, 2013 Share Posted January 24, 2013 I have just recieved from HK a Frsky telemetry module for my HItec Eclipse7. It came with a V8FR-II NON telemetry Rx. The module was supplied with both switches OFF and in that state will bind with the Rx by holding theF/S button ON while powering up the Rx. Now according to the manual the Module should be in non-telemetry mode (switch 2 on) to operate with this Rx. Furthermore the instructions state that with the module in telemetry mode binding is achieved with the supplied binding plug across the signal pins of channel 1 & 2 of the Rx. If I do put switch 2 to ON then I can't bind by any method. Now I am perfectly happy with the arrangement that I have ie. module in telemetry mode and binding with the F/S switch and have successfully range tested and flown with this setup. Its just that its all contrary to the instructions - any ideas please, have I missed something? Also when all is stable and working and Rx is bound, there are no leds lit on the Rx and apparently the red one should be on with the green one flickering with reception of signals.

John Cole Posted January 24, 2013 Share Posted January 24, 2013 This is how I read it: the bind procedure depends on whether you want to bind in telemetry mode or not. In both cases before you try to bind the Rx you must start the Tx in binding mode, by pressing down the F/S button on the Tx before switching the Tx on. The red LED on the Tx module should then flash, indicating it's ready to bind. Are you doing that / is the LED flashing - you did not say so. For non-Telemetry mode: set the switches to V8 mode 1-OFF, 2-ON. Only then do you power up the Rx, with the Rx F/S button pressed. Its red LED should then flash. For Telemetry mode: set the switches to D mode 1-OFF, 2-OFF and connect CH-1 and Ch-2 pins with the jumper. Then power up the Rx (no need to press button). Its red LED should then flash. You must then turn off both the Tx and Rx (and remove the jumper if you used it), and then turn them both on. Only then should you see a solid red LED on the Rx, with a flickering green one.

Colin Naylar Posted January 24, 2013 Author Share Posted January 24, 2013 Thank you John, I believe I am doing everything as you suggest. The reciever is non telemetry so there is no doubt that the Tx switches should be 1-off and 2-on but I get no binding at all in that configuration. I shall go through it all again and get back to you. Its just a puzzle that it actually works without the correct indications. Quote Link to comment Share on other sites More sharing options...
Welshboy Posted January 24, 2013 Share Posted January 24, 2013 I wonder if the software has been updated, but not the manual. Have you tried downloading the most upto date version from the website? Quote Link to comment Share on other sites More sharing options...
John Cole Posted January 24, 2013 Share Posted January 24, 2013 Although it's a non-telemetry Rx it is designed to work in both modes, that is with switch 2 set to Off for V8 mode or ON (with the jumper in) for D mode (= telemetry mode). Do you get the red Tx LED flash when you set the Tx to Bind mode? Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted January 24, 2013 Share Posted January 24, 2013 This sounds to be the latest V series receiver which will work fine with a transmitter in 'telemetry' D mode, ie both switches off, but it just doesn't send a signal back. The instructions with mine did explain this. To use it with the tx module in non-telemetry V mode you don't use the jumper when binding. I've not tried mine in V mode as my reason for buying it was to avoid the need to switch between modes for different models.

Colin Naylar Posted January 24, 2013 Author Share Posted January 24, 2013 Welshboy, I am not brave enough to re-flash the Rx at this early stage! John, I don't get a solid red led on the Rx at all. After it has been bound and I subsequently reconnect power then I get a single red flash and then a continuous low level green led and then all is well! Bob, I think you may be right here. There may also be a problem over the definition of telemetry as apparently there is a feedback from Rx to Tx of signal strength which will sound a warning bleep if low.

John Cole Posted January 25, 2013 Share Posted January 25, 2013 But does the Tx module red LED flash when you set the Tx to Bind mode? After binding and in normal operation the TX red LED should be lit, with the green Tx LED flashing. Quote Link to comment Share on other sites More sharing options...
Colin Naylar Posted January 25, 2013 Author Share Posted January 25, 2013 Yes John, the Tx module does behave as you say - the red led flashes continuously and the unit bleeps in time. Upon powering up the Rx with the button held down to bind it (not an easy manoeuvre) the red led on the Rx flashes once. Quote Link to comment Share on other sites More sharing options...
John Cole Posted January 25, 2013 Share Posted January 25, 2013 That's exactly what the Rx manual says should happen. But if you switch off both Rx and Tx and then switch both on (Tx FIRST), then the Rx green LED should come on continuously, showing that it is locked to the Tx. The Tx red LED should also be on continuously, and the green Tx LED should flicker. Quote Link to comment Share on other sites More sharing options...
Colin Naylar Posted January 25, 2013 Author Share Posted January 25, 2013 Thanks John, I think I have been confused (easily done) by the settings for the switches and the fact that the green led in the Rx is very dim and not well aligned with the hole in the case. As I said before it is working fine and I really needed some assurance that I had not missed something - thanks again for your help. Quote Link to comment Share on other sites More sharing options...
