TDET1
Cable between LNB and the LNB head is disconnected. When cable disconnect
test mode is applied, the LNB linear regulator is disabled and a 1 mA current
source is applied between the BOOST1 and LNB1 output. If the LNB volts rise
above 21 V, CAD1 will be set to 1. The CAD1 bit is reset if the LNB volts drop
below 19.95 V.
See description for CAD1. This indicates status for channel 2.
Tone Detect. When tone is enabled by whatever option, or if a tone signal is received
from the LNB, TDET1 will be set to 1 if the tone appears at the LNB1 output. When
the tone is disabled and no tone is received from the LNB, TDET1 is reset.
