I am hoping for some assistance. I recently purchased a router from a sign shop that replaced it with a new machine. I was on site when they showed me the router running before picking it up. I haven't been able to get the PC to connect with the router to transmit files. I tried a new data cable but that didn't work either. I'm not sure what else to do or check, all the fuses are good in the control cabinet and have power to the pendant, it can cut a rectangle once I enter all the settings from the table. I have attached 2 photos, 1 showing Available Machines and the other showing Communication. The LRC shows no connection and no current .I followed many explainer videos to get a solution out of it but,did not any. I don't know how this happened. Please help me out.

Any help will be appreciated.
Thank you.
