2.10.4 Optimization of Individual ACU-1000 Extensions
Once the radio, satellite phone, or other communications device is connected to the ACU-1000
using the proper interface cable, the interface must be optimized to fit the individual
communications device (usually a radio) and the circumstances of its use. A flow chart is
provided to assist with this task. This flowchart assumes that the ACU Controller is being used
to adjust the DSP configuration, but the same steps may be performed using the WAIS
Controller or the HSP-2A keypad.
The detail notes that follow each flow chart provide additional explanations when necessary. If
the installer has had some experience setting up an ACU-1000 interface it may prove sufficient
to simply follow the flow chart. The notes are tagged by the number of each question posed in
the flow chart (e.g. QA3 is the third question in flow chart A, and “QA3” is noted at the top of
the question diamond). This allows the user to reference the notes only for specific segments
of the flow charts.
Flow Chart A is the Overall Setup procedure. Charts B & C are used only if certain conditions
exist:
• Use Flow Chart B only if Application Notes are not available
• Use Flow Chart C only if the radio being interfaced is part of a trunked system
Flow Chart B guides the installer through a simplified version of the steps taken by Raytheon
Systems Engineering when a new radio interface cable is designed.
Flow Chart C provides a systematic procedure for determining the proper amount of TX Audio
Delay to compensate for the Trunked System’s channel acquisition delay.
After an individual extension has been optimized, that port’s operation with the other parts of
the ACU-1000 system must be checked and optimized if necessary.
Following the flow charts and explanations is a description of a procedure for operational
testing and final adjustment. See Section 2.10.4.4.
