LATN4
Receive Line Attenuation Indicators. Convert this binary output to a decimal number and multiply
by 2.9 dB to determine the approximate cable attenuation as seen by the receiver.
For example, if LATN7-4 = 1010
(= 10
), then the receiver is seeing a signal attenuated by
approximately 29 dB (2.9 dB
x
10) of cable. This approximation assumes that a 3 V pulse was
transmitted.
