RFTB Remote Interface Connector (J5)
The RFTB remote interface connector (J5) is a 26-pin, MS style female connector. It
routes serial interface signals, KP-10 power, and uplink and downlink fault information
from Unit B J2 remote to RJU-2000 J6, interface M&C connector. Refer to Table 3-5 for
connector pinout.
