LDC2250 defaulting to analog?

7 years 3 months ago #29528120 by Sunin
I have a futaba r2004gf receiver which does green light to my transmitter. I have it connected via both channels and the battery eliminator. I check the status and get 3 blinks, which looking up on the data sheet means it is defaulting to analog. I want it to pick up the rc input but it has not been successful. I could not find any sort of troubleshooting guide to help. Very frustrating considering the reason I bought roboteq was from the many reviews of it being pretty much plug and play from an rc standpoint. Help!

It normally is a plug and play experience.

But is it aways a good thing to first exercise your motors with the controller connected to the PC and using the PC utility.

This way you can also check the command modes and their priorities. Analog is normally disabled by default and in any case, analog mode will only be entered if the input is centered for a moment (i.e at 2.5V).

Ok is there a guide on connecting it to a computer? I only received the rc connector with the kit. I will go read the user manual again.

One question assuming it defaults to analog won\'t it recheck and see an rc signal or does it get stuck in analog mode once there?

You guys could use some quick start guides and videos to help the less experienced guys like myself. Thanks for the help I was hoping to avoid hooking to my computer, but will proceed down that path soon. I\'m going to test both motors to ensure they work and eliminate othe simple stuff first. I mounted the controller on the bottom aluminum diamond plate under a harness for the batteries so not an easy disassembly.

My request again how are u guys hooking an old ass 15 pin rs232 cable to a computer. USB to db15??? I do not own a computer from the 80\'s... Hell only one of my computers even still have a serial port at all and it is only 9 pin

How about u just issue me an rma? I opted for this model because I never ever was going to hook it to a computer, otherwise I would have gotten the mdc version with USB

The PC utility will work on practically all PCs, particularly with newer versions of windows. Try a different PC. Get a USB to serial adapter if no com port is present on the PC. Battling windows is always time consuming and it may not work in the end.

Finally after some 5 hrs of patching I was able to get the software to load! I see it is throwing an over voltage fault. Seems my 4 12v SLA AGM batteries are being overly productive with 52.5v. Any suggestions? I was planning on draining them a touch tonight with a spare motor. Ok last question since I\'m not seeing any sort of user manual for the PC utility is the run page with the slider bars toward the middle bottom where I could as you said, \"Exercise the motors\" at, if not where do I do that? I was able to set the default to pulse, pulse, rs232 for the command priority successfully. It was set to rs232, pulse, none

Thanks for the help!

You can change the overvoltage limit up to 55V.

For priorities, you can keep RS232 as the first priority. This way, when connected to the PC, the controller will respond first to the slider.
