Thanks Rand, I will try getting a new PLM

Hi all I am in need of some assistance. I am new at this stuff and have just received an ISY 99i pro and a PLM 2412s. I am having a problem communicating between the two of them. Whenever I plug in the PLM in the ISY will power up and then light the Power LED, RX LED, the TX LED, and then the MEM LED. After a second or so the MEM light goes out and then briefly after that the TX light goes out. The RX light continues to stay lit. I noticed that at the same time the TX light goes out there is a quick blink on the PLM. I have tried numerous cat5 cables and have done my best to make sure the pins are bent up for good contact. When I go into my administrative console and go to tools and check diagnostics I check the PLM status and it says its not connected. Please, any info would be great on what might be the issue.
