I have just got an used AB7007 communicator from eBay. I am trying to set a new IP but when I connect the Ethernet cable to my switch, none of the switch LEDs turned on. it seems there is no device connected. I tried two other cables but the same issue. I also changed the dip switches on AB7007 for preset IP like 192.168.0.2 but it did not work.
the communicator’s status LEDs is as below:
1- Blinking Green
5- Solid Red
6- Blinking Green
Should I do something else to be able to communicate it? or the device might be malfunction?
