Disconnecting The Ground - Extron electronics DTP HDMI 4K 230 User Manual

Disconnecting the Ground

If you cannot resolve a ground potential difference between the transmitter and receiver installation sites (as
suggested by a missing or unstable picture), remove the ground connection between the units as follows:
NOTE: Once you have removed the ground jumpers, the DTP HDMI 4K 230 cannot extend analog audio and
one unit cannot remotely power the other. No analog audio is output and each unit requires a local power
supply.
1. Disconnect any cables and remove the transmitter and receiver from any rack or other installation option.
2. Remove and retain the screws securing the covers to the transmitter and receiver. Slide the covers forward
slightly and lift them off both units (see figure 9).
