Acm - Adaptive Code Modulation; Table 3: Max Power Input - Trango Systems TrangoLINK APEX 18 User Manual

The maximum power input, measured by RSSI, is as depicted in Table 3. If your RSSI value is
higher than listed for the modulation that you are running, you may incur bit error rates as well
as possible damage to the system.
ACM – Adaptive Code Modulation
The ACM feature of the TrangoLINK APEX™ works in conjunction with the MSE of the
unit. The ACM command is an on/off command. Once ACM is enabled and link is
degraded to the MSE threshold specified, the radio will shift down in modulation and
speed based on the setting of the ACM table (Table 4).
