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.

When finished reading or programming user EEROM, push any of the first four buttons to exit the programming

mode.

Read Firmware Version

Firmware version and be read by simultaneously pressing buttons 1 and 2. The firmware version is read on the

channel status LEDs in binary for as long as the buttons are held. For example, if LEDs 1 through 6 are off and

7 and 8 are on, this represents binary 00000011 or firmware version "3."

Note: If buttons 1 and 2 are pushed carefully at the same time, it will not disturb the currently selected audio

channel.
