I have used 3 daisy chained CTB16PCg3 controllers for the last 4 years with no problems. This year I cannot get box 3 to stop green light flashing and begin to work.
1. Rebooted the number 3 controller by moving the JP3 jumper to 5&6, powered, quick flash, unpowered, moved back to JP3 jumper back to 4&5 to reset controller.
2. Plugged the controller directly into the computer through SC485 serial connector and removed all additional controllers connected to computer. Went to light o rama hardware and ran the "auto configure" , I then received the message to connect 485 serial connector to the serial port and to make sure power was on ( which both were done). The following message was then received "Port not Found".
3. I unplugged the number 3 controller and re-plugged controllers 1 and 2 back into the computer through the same SC485 serial connector and they both work perfect.
Any thoughts on why I can't get this controller to work? The Ethernet connection from the computer seems to be fine as it works great when I plug in controller 1, so it won't let me auto configure to set the ID number. When I push the Refresh button in HU is says "0 units found" It continues to have a slower green flashing light.
Controllers 1 and 2 continue to work once re-connected so I know that it is getting signal from the computer.
Any thoughts on what can I do to fix this ASAP?
