UHF Receiver Board (Q13564)
Mounted on the DCB, the UHF Receiver Board receives 12 VDC from the DCB. The board
also receives information from UHF antennas over J2A or J2B and processes the UHF signal.
This receiver has to comply with FCC and in-country communication protocols such as ETSI.
For this application the ETSI protocol is required for Asia and Europe.
