Hi and Thank you in advance, So i have tried to build Setup Bose Powermatch PM4500N with Sound Processor ESP-880 with CC-64 Control Center. i have connected them all over ethernet switch via lan cable with my laptop. so i have two problems i cannot see the ESP-880 device in CSD application and i cannot see also the CC-64 device in CSD application so i dont have access in these two things. i cant make update firmware like that. Where is exactly the problem? Thank you.
