Supernova26 March 30, 2014 Share March 30, 2014 Hey guys, I picked up a non functional DC8 today and I am looking for some troubleshooting help. The DC8 outlets are all off with no power being delivered. The voltage regulator sends a constant 5V to every chip in the board and all individual triacs measurements are ok. I connected the unit to the apex but I don't know if the apex is able to see the unit. Has anyone seen this before on the DC8? Link to comment Share on other sites More sharing options...
st9z March 31, 2014 Share March 31, 2014 I haven't experienced this before. Have you tried using a different USB to connect the DC8 to the main module? Maybe the issue is with the connection wire. Link to comment Share on other sites More sharing options...
Supernova26 March 31, 2014 Author Share March 31, 2014 The DC8 does not use USB connection. It's the old 4 pin telephone line. Link to comment Share on other sites More sharing options...
Origami March 31, 2014 Share March 31, 2014 Are the address switches set up correctly? Are you addressing the DC8 correctly from the base unit? Did you add the DC8 module to the Apex's address space? (I don't think that the Apex can recognize it automatically.) Was it working for the last owner? Link to comment Share on other sites More sharing options...
s2nhle March 31, 2014 Share March 31, 2014 Tom, I believe it was bought from someone that just posted for sale on wamas recently. It was nonfunctional. Have contact Apex technician for the issue. They respond very fast and can troubleshoot the problem remotely. Link to comment Share on other sites More sharing options...
Supernova26 March 31, 2014 Author Share March 31, 2014 Tom, s2nhle is correct. The unit was nonfunctional but i like to tinker with stuff so it's more like diy project for me. Link to comment Share on other sites More sharing options...
Origami April 1, 2014 Share April 1, 2014 Since all of the outlets are out at one time, it sounds like it's either not receiving commands, not recognizing the commands, or cannot process the commands. I believe that there's a green light near where the RJ-11 connector is located and that it blinks when the unit receives command traffic over the link. Are you seeing that light blink?

Supernova26 April 2, 2014 Author Share April 2, 2014 Thanks Tom thats good o know. The light does not blink. I believe it's not receiving commands correctly. There is a photo coupler ps-2501-2 chip that has a slight color change possibly from overheating. I don't know how to test this chip. I will probably buy one and replace it.

That would really be cool if that's all it was. Keep us posted. Link to comment Share on other sites More sharing options...
