  • DSATX 3 blinks?

    i set my dsatx to keep the 5vsb on so that i could do standby. when acc goes low, the computer goes into standby like it should but when i look at the dsatx it's showing me 3 blinks every few seconds. in the user manual for 3 blinks it says n/a. is this the expected behavior of the dsatx in sleep mode with the 5vsb still hot?

    If i'm not mistaken, 3 blinks means its in hibernation mode. In that case it would be normal. Correct me if i'm wrong though..

      So i discovered that not only is the 5v still hot, the 12v is also still on because if i manually hit the power button, the computer will turn on even though acc is low. I don't think it's working correctly. Anyone have any ideas?

        We have an update for this that we are testing. It is version 115 and it will hibernate more solidly..

          can't say enough good things about jeff and the dsatx. the support he has provided has been great. from researching on the forum it doesn't appear that too many people use s3 standby with the dsatx since there are less than 10 threads about the topic. most here would recommend s4 hibernate over s3 standby to prevent degradation of your battery but that's a different topic.

          in getting my new install up and running, i discovered a quirk with the dsatx when enable5vsboff is set to 0. because of some hardware driver issues my computer would randomly decide to hang when going into standby. in firmware 114 the dsatx would wait patiently for the computer to go into standby and would only kill power once the battery voltage dropped below the lowvolts threshold. there was at least one occasion when i left my car for a few hours only to come back to discover that xp had hung going into standby and had been drawing full power the whole time i was gone. when brought to jeff's attention he modified the code for me and sent me firmware 115. here's how it works. if enable5vsboff = 0, when acc goes low, the dsatx will send a pulse to the power button and the computer will begin to go into standby. if for some reason after 90 seconds the computer has not yet gone into standby, the dsatx will go ahead and pull the plug and go into deep sleep.

          i have since figured out my hardware/driver issue but it's great to know that when i leave my car, if the computer does not go into standby correctly, the dsatx will pull the plug on the misbehaving machine. one side effect of this modification is that in 114 you could manually power up the computer even if ACC was low. it is convenient to be able to power up the computer without a key in the ignition but having a failsafe is much more important to me. in 115 if the system is in standby drawing only from +5vsb and the dsatx is in hibernate mode and you try to manually power up the computer, the dsatx will see the power on signal and treat it like the computer got hung up and pull the plug and go into deep sleep mode. as jeff mentioned in his email, this is actually a good behavior for those using standby and who don't have a master kill switch and want a quick way to put the dsatx into deep sleep for times when they know they won't be driving the car for a few days.

          the new firmware does exactly what i need. big thanks to jeff for his great support and for a great product.

            Thank you for this great post!!! I have the 115 firmware too, and saw these 3 blinks. A little search and I got the above explanation.

            Just to make sure, you left enablesleepon=1, right? So that it can go to deep sleep.

            I have just left enable5vsboff=0, so that the 5v allows sleep mode. So this should be good.

            Thanks a lot!

            Boy, love this forum! Repped!

              how are you guys updating your firm ware? I was under the impression that the brainstem is required for that and that most people have problems with the brainstem. Do i need to send it to jeff to have it updated?

                ripplinghurst, i have enablesleepon=1 and enable5vsboff=0 and it leaves my carputer in s3 standby.

                sonicxtacy02, i also have trouble with the brainstem causing the dsatx to behave abnormally. i have the usb version so what i was able to do is use my laptop to load firmware and change settings on the dsatx. i was never able to use the carputer connected to the dsatx with the brainstem to change settings or monitor the dsatx.

                on a different but related topic, with hybrid sleep and windows 7, i think it would be the perfect setup to have the dsatx keep my carputer to in s3 standby for 3 days before going into deep sleep and pull the plug on the 5vsb and go into deep sleep if any longer than 3 days, and next time i drive the car it comes out of hibernate instead. i'm thinking could accomplish this by bumping up the dsatx's lowvolts value up from the default 11V to high 11's or low 12's but i'm not that clear on what value i should use and how much time it would give me in standby. maybe someone with a little more knowledge about voltage, amps and what not can chime in here.

                    I'm using a very old pentium III laptop, that I take it to the car and plug the brainstem to it's external good old COM port. It's very reliable that way. I can never connect it to my carputer, it won't work properly.

                    I know that somebody posted on the dsatx forum that he connects the DSATX to the Carputer bypassing the Brainstem altogether via a "phone data cable", which I believe it's one of those COM-TO-USB motorola or whatever cell phone cables? I wonder what the brainstem is supposed to do anyway.

                    The post if from a guy called Marcel, and I wonder if it's the same MarcelIP from CF forums and here? I forgot to post more info about it.

                      THANKS!

                      on a different but related topic, with hybrid sleep and windows 7, i think it would be the perfect setup to have the dsatx keep my carputer to in s3 standby for 3 days before going into deep sleep and pull the plug on the 5vsb and go into deep sleep if any longer than 3 days, and next time i drive the car it comes out of hibernate instead. i'm thinking could accomplish this by bumping up the dsatx's lowvolts value up from the default 11V to high 11's or low 12's but i'm not that clear on what value i should use and how much time it would give me in standby. maybe someone with a little more knowledge about voltage, amps and what not can chime in here.

                      How long does it take to go to deep sleep right now? My 75Ah battery doesn't keep 12 volts for much longer after the engine is turned off, it's mostly high 11's from 15 min after engine turn off to mid 11s days after. How does yours behave?

                      So to get the exact 3 days figure you must first figure out how much time is taking right now and go testing from there, experimenting every .2 or .3 volts.

                        i haven't actually tested this yet. i have yet to get windows 7 into the car so for now i'm still running xp with the lowvolts setting at the factory default of 11. i guess the better question would be what is a safe voltage to use so that my battery will always be able to start my car and doesn't die prematurely. i've researched here and on the web and have read that it depends on the amperage more so than the voltage and it fluctuates depending on battery health but like i said before, i'm no expert on car batteries.

                        with lowvolts set to 11v, if i leave my car for more than 4 days, the car will just barely start and the dsatx still brings my carputer out of s3 standby so i assume my voltage was still above 11. i think i'll just bump the lowvolts to 12 and let it sit for a few days.

                          I think I was way off regarding my battery's health. It actually stays around 12.37v 15 min after turning off the engine.

                          Another user pm me and recommended to bum the lowvolts DSATX variable to 12v (currently is at 10.50v), as you are suggesting.

                          You said at 11v you get 4days? Yeah, that's more than enough for me, 24hs is what I need, 12hs I'll be happy enough. Are you testing on the G35? I wonder if it's the same 75Ah battery as my FX.

                          You can bump it into 12v and tell us what happens, I'm going to bump it to 11:50v and see what happens and I'll report back.
