7.3.5.9 MaxReceivingGain
This request is used to modify the Max Receiving Gain of the AMIS−49587. The Max Receiving Gain can be set from 1 to
42 dB by step of step 6 dB, or unlimited. The data value for the request is in the field 01 to 0F by step of 2, it indicates a Max
Receiving Gain of ((N − 1) / 2) * 6 dB; or 00, which indicates an unlimited Max Receiving Gain. The data value for the Confirm
is in the field 00 to 07, indicating a Max Receiving Gain of (N * 6) dB, or 08, which indicates an unlimited Max Receiving
Gain.
