AMIS−49587
Min Delta Credit
Description: This request is used to read the Min Delta Credit in the AMIS−49587. Once the request sent to the AMIS−49587,
the Min Delta Credit is automatically set to 7. The AMIS−49587 answers with the value of the Min Delta Credit (before it was
set to 7)

MaxTransmittingGain
Description: This request is used to modify the Max Transmitting Gain of the AMIS−49587. The Max Transmitting Gain can
be reduced from 0 to 21 dB by step of step 3 dB. The data value for the request is in the field 01 to 0F by step of 2, it indicates
an attenuation of ((N − 1) / 2) dB. The data value for the Confirm is in the field 00 to 07, indicating an attenuation of N * 3 dB.

Synchro
Description: This request is used to modify the synchro parameters: the synchro type and the synchro bit. The value of the
synchro bit field is 0 if the synchro bit is automatic, or (2 * N) + 1 if the synchro bit is fixed, where N is the synchro bit value
(0 < N < 7). You can add 16 to this value to enable synchronization on special frame

MaxReceivingGain
Description: 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 6dB, 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.
