![]() ![]() I always had with empty batteries often because the device was in standby mode and in the course of time were empty, I have considered a solution and indeed an on and off switch after the device goes down in standby mode, I turn it off thus it can not consume power and keep the batteries.Īnother solution I’m thinking about is when not in use connecting the mux to a power source (battery charger). This was (my personal opinion) because of the continuous battery drainage that pulled the voltage so low the batteries eventually got broken. The same problem occurs when disconnecting the mux from the car.īut as I did not remove the rechargeable batteries after use I noticed that some of the inserted batteries went dead after a while. ![]() I’ve used my (Chinese clone C4) MUX from the first beginning without batteries.Īfter some time I inserted rechargeable batteries just because I had the same idea as mentioned a few times above -> The voltage drop/peak when starting/stopping the cars engine is not good for the electronic components of the mux. Cal.ini sd c4 free#I think heat with wifi card is a problem because card itself is heating adding to the heat that pcb’s itself produces, with no card installed less heat inside the mux and heat can go exit through the free slot of card, making a grill on the grey plastic piece will help allowing heat to go out of mux, surely extending its life. Seems that error came from heating the wifi card and not correctly drainage from hot air.Īdded to this, using mux without wifi card save around 0.4v consumption, xentry will see around 0.4v more voltage,so safer voltage for programming,etc… I dont have wifi card installed, better work always with lan, i dont see too much work in connecting just a cable when making a work. Try to use mux on lan( without wireless card inserted),and you will have no more ‘check batteries’ error on display. You can avoid this problem by letting the laptop only use its internal battery, or by using a 120vac adapter to power the laptop.(or the 12v-to-laptop plugged into a totally separate external battery). ![]() If the SD Connect C4 diagnostic device expects to be able to connect the laptop’s signal “ground” (or 0v or negative) directly to the Sprinter’s 0v/negative/frame smoke can happen… you’ve suddenly got the power adapter fighting the two “negatives'” 6 volt difference across the diagnostic device. The 12v-to-laptop adapter then creates the laptop’s desired 18v by pushing the *negative* feed “down” an addition 6 volts … the battery’s +12v is fed directly to the laptop via a wire. Many 12v-to-laptop devices have a “common positive”. I am pretty sure that the consensus view is to run it without batteries and ignore the warning on the display.īTW: you should always connect an external power supply to your van while using Star.Īnother thing to watch out for is to NOT use a 12v-to-laptop adapter powered by the Sprinter when you’re using a diagnostic device that also connects to the Sprinter. As a result, the battery charge error will appear only due to the “fault” of the batteries themselves. Revision of the device circuitry eliminates the second reason. a chaotic error caused by the feature of the circuit design of the multiplexer.wear or not the corresponding capacity of the installed batteries.The error is accompanied by the message “Insert / check batteries” “batteries can not be charged” on the instrument display. Multiplexers SDConnect C4 Chinese production is peculiar, randomly appearing, battery charge error. I had the van idling in the driveway with 14.2v in the top right of laptop screen so wanted to know as to how if atall i charge the multiplexer, the laptop had 82% battery life when the ! Check batteries! appeared on the multiplexer. Questions: where does the multiplexer get power from as a battery icon appeared in the little window on the multiplexer and a warning !Check Batteries! after this appeared an error screen appeared on the laptop screen along the lines of communication had been disrupted (i was checking the block heater at the time) due to low voltage. Very pleased with SD Connect C4 when plugging it into my van (2002 311 CDI LWB UK spec) to run a ‘quick test’, first attempt and found everything simple to navigate. ![]()
