Setting up the ACU-1 from the Front Panel
Introduction
The switches that are normally used for channel selection can be used to change some operating parameters
of the ACU-1 that may not be accessible through third party software. It is impossible to predict if third party
software will react properly if unsupported adjustments are made in hardware. If you make changes to the
system using the information contained in this document, you are accepting the responsiblity for making
alterations to the system that may not be supported by your software vendor or by Sine Systesm, Inc.
Set EEROM to Factory Default
This is the same as command 3B (hex) and is executed by pressing buttons 1 and 8 simultaneously for at least
one second.
Program User Settings from the Front Panel
(firmware version 6 and later)
All user programming in the ACU-1 can be read and altered from the front panel.
To enter the front panel
programming mode, press buttons 1 and 3 simultaneously for at least one second. The POWER/SYNC LED
will begin flashing to indicate that the programming mode has been entered. The front panel will display a
memory address in binary using the left 8 LEDs of the left VU meter. The data at that address is displayed in
binary on the channel LEDs:
The starting address will be 27 (binary 00011011) which programs the "Box Address." The memory address
may be changed using buttons 5 or 6. To change the data at that address, push buttons 7 or 8. If data is
changed, the new data will be stored in EEROM and will unaffected by a power failure.
