ML4000 Service Manual 19
Console Computer and Operating Software
Operating Software Version Number
You can check the current version number of the
ML4000 software running on the console using a
PC connected via RS232. Instructions for this are
provided on the Allen & Heath Internet site.
Loading New Operating Software
Check the Allen & Heath Web site for the latest
version of console software. New software is
loaded from a PC via the RS232 port.
IMPORTANT ! The current console settings and
snapshots may be lost when you load new
operating software. If you wish to keep your
settings and snapshot contents, first archive them
using the dump out facility. Restore these after
loading the new software by using dump in.
Download the software from the Allen & Heath Web
site to your PC computer. Connect the PC RS232
port to the console RS232 port using a standard
pin-to-pin (not null modem) 9-pin serial cable. Set
the console rear panel switch to the RS232 position.
Power up the console. The console awaits data
from the PC. Follow the instructions provided on
the Web site for loading the new software into the
console. When completed make sure you set the
console rear panel switch back to its normal
operating position, typically MIDI.
Power Up and Power Down
The console settings are saved when power is
removed. On power up these settings are restored.

To Reset the Snapshot Memories

Important Note:
1. If a sidecar expander is used with the ML4000 make sure it is running the same version of
software as the master console.
2. If it is necessary to replace the CPU assembly make sure the jumper links are correctly set on
the replacement assembly. These are set differently for the master and sidecar consoles.
Refer to drawing D44 for details.
3. If it is necessary to replace the MIDI/PSU assembly make sure the jumper links are correctly
set on the replacement assembly. These are set differently for the master and sidecar
