I have gcanbox's GCAN-4128.. but it did not come with an EDS/DCF file. So using a similar devices' eds (PCAN-MicroMod Digital 1) and a few tools (Delta Electronics EDS Builder 3, CanOpen Architect Mini, port CanOpen Design Tool)..I cobbled together an EDS. However the documentation is incomplete, so my EDS probably has issues* For example, the GCAN pdf lists NOTHING for index 0x1A00, 0x2000, 0x2010 and 0x2100. And index *0x1800* says transmission type set to 0x2000(?). So to get some insight on what is actually in those OD entries, I connect a USB and PCAN Magic to read OD Entries: 0x1400 : 0x201 (RPDO1 Config COBID) 0x1600 : 0x2100 01 08 (RPDO1 Config Mapping) 0x1800 : 0x181 (TPDO1 Config COBID) 0x1A00 : 0x2010 01 10 (TPDO1 Config Mapping) 0x2000 : Entries 0+ are 0x60 , 0x00 (?) 0x2010 : Always 0 regardless of DINs PCAN Magic won't read from 0x2100, and won't write to RPDO1 (0x200+1) saying it's an invalid area.. yet if I use PCAN-View, I can change DOUT (500kbps, Standard Id 0x201 message with one data byte ). Also, I see the device transmit TPDO1 (ID 0x181) every 20ms immediately at power-on. *I tried Python CanOpen, but node.tpdo.read() fails. At this point, not sure if I should stick with free/open-source ( CanFestival , Lely CANopen, CANopenNode, KickDrive) or try something commercial (TKE CanTrace, Vector CANoe.CANopen, EmSa CanOpen Magic, CodeSys CanOpen, emotas CANopen Device Explorer , Moon CanOpen Test Tool etc). Or perhaps, even non-CanOpen specific software like plotjuggler-CAN-dbs?

I would buy the ulralites until Vuzix can make a phone replacement that looks like the ultralites. If they are going to look as bulky as the second pair he showed Ill be happy with the smaller phone display only glasses personally.

Hello, good morning, I am contacting you, to be able to comment on the following situation that occurs in my vehicle, it was presenting an electronic problem, without knowing I changed the battery, and nothing, I went on to change the alternator regulator, and well, I I bought, it charges over 14.5V, and I considered the fault finished, one day cleaning the interior, I left the radio on, while I cleaned, and nothing after a few minutes, the voltage began to drop, less to less, until that the battery discharged at that moment, I was surprised because that had never happened to it, I did another test, with the battery charged again, I gave the contact, after a short time, equal to less than less, that in a moment the battery goes, I recharge it, install it, and leave it connected for approximately 2 months, until I realized that the red alarm light was not flashing, I checked it and discharged, that did not happen in the past either, did the current leakage test with the multimeter, because I told myself what And this would have to be a current leak, it is the logical thing to think, and what was my surprise, that the value it gave is 0.02, with the battery just charged, so there is no current leak, and then what is happening to you?, I have explained everything to you with hairs and bones, to see if you could help me determine the cause, because I do not understand it nor do I know what else to do, regarding what I am explaining to you, I await your prompt clarification, please, greetings.
