Just a picture showing what I am working on. I also think this is the first picture with Ethernet mounted. Both these boards will soon come in new versions.
I need to experiment a bit with picture resolution since my screens now are 4K – I used to reduce pic resolution by copying pictures through a 2K screen to make them more user friendly – that don’t work anymore.
The main board at right was made 2cm short of full length to enable 5 x DSUB9 in front panel with 1:1 cable to the ports. What you see here is a test cable used to communicate port to port. Firstly I detected that port 2 on the cable was not properly connected and secondly I detected that the 3rd port had crossed tx/rx – but, I got the CANFD ports working. Using CAN ot RS485 I usually either use DSUB9 or simply screw terminals. M12-5 and NEMA2000 (left) add a different perspective. I am quite eager to test both NEMA2000 and an increased speed version to see what speed/distances that can be used.
But, that’s work for another day. I lost power in my house yesterday and realized the reason was that a plug-board in the basement had short-cutted. The reason it shorted had something to do with 20cm rainwater on the floor. It has been raining so much that water now comes in through the floor rather than leaving out – so water pumps was installed this morning. Only minimal damage done, but this scare me a bit – I did not thing this was possible and have even bragged about my basement beeing dry – I never considered the water to come in from the drains in the floor. Oh easter fun!
