My original H4P5-H48-HRL-120 Homeworks processor recently died. Everything was working fine until 2 weeks ago. I have replaced the processor with an identical model purchased on Ebay that has had the battery replaced. I have uploaded the program and all wired lights & keypads are working again, but I am unable to get ANY of the RF devices to upload or be recognized by the new processor.
As you probably know, the RF devices communicate through Link 8 on the board. I am suspicious that the Link 8 connection on the "new" board may be faulty. Neither the Tx or Rx lights are on next to Link 8.
I would very much appreciate any help or guidance here to get the RF devices to upload to the new processor.
