does my MK3 work?

I am trying to configure a MultiPlus using a MK3 but when I plug in the Cat5 cable into the MK3 I get the MultiPlus go into error mode and get 14 (Device cannot transmit). Using a HP computer with Windows10, I see the MK3 is on USB serial port COM3. My Multi firmware sticker says 2702481.VFD

MK3

I forgot to add this information, I inspected the RJ45 Jacks and none of the pins were bent. I ran a TDR on the cable, all 8 lines are fine, it is 7 ft long, straight through (pin 1 to 1, 2 to 2, .....8 to 8)
