Firmware Upgrade
This allows you to select an OS upgrade file to
upload to the DX810 as they become available.
Click Select File in the Firmware Upgrade window
and the Select OS Upgrade File dialog box opens.
Browse to the location of the OS upgrade file (with
a .pkt extension) on your hard drive or floppy drive
and click Open, then click Upgrade. You can monitor
the progress in the Firmware Upgrade window.
Set Lock Code
Select this to view and change the four-digit
Administrator Pass Code or User Pass Code for the
DX810. The code must consist of four digits. Use
the Panel Lock button in the Top Section to lock and
unlock the front panel controls (User level), or use
the MODE button on the front panel to lock the
controls. Refer to page 13 for more information on
using the Lock mode and password protection.
Configure COM Ports
The DX–810–PC application uses COM1 on the PC
by default. If necessary, you can change the COM
port used by the application. Click the PC Com Port
pull-down box in the COM Port Setup window and
select the desired COM port.

– DX810
Note: The DX–810–PC application defaults to
COM1 whenever it is restarted. This is regardless
of whether another COM port was selected in a
previous session. To permanently change the
default COM port setting, you must open the file
named DX8.ini (located in the System folder where
the DX–810–PC application is located) with
NotePad. Change the line "dspport:0" to
"dspport:1" to change to COM2, "dspport:2" to
change to COM3, and so on.
The DX–810–PC application uses 115.2k baud
transmission speed for both COMM PORTS. Some
third-party control systems require a lower baud
rate. If using one of these systems, the DX810 rear
COMM PORT baud rate can be changed in the
COM Port Setup window. The front panel COMM
PORT always operates at 115.2k baud.
Note that when the rear COMM PORT baud rate
is changed from 115.2k baud, the PC application
can no longer communicate with the DX810 via this
port. You must use the front COMM PORT with the
PC application in this case.
Set Temperature
Select this to open the Delay/Distance Parameters
window. The temperature value entered here is
used to calculate the delay time in the Delay Line
output processor (the Delay button). The speed of
sound varies with air temperature, so it is necessary
to enter the ambient air temperature here to
calculate the time delay required as a function of
distance traveled.
Click and drag up or down in the Set
Temperature box to change the temperature
setting from –40.0° F to 122° F (–40° C to 50° C).
Change from Fahrenheit (US Units) to Celsius
(Metric) in the Set Units box. This also changes the
distances in the Delay Line window to Metric.
Set Ramp Time
Select this to open the Preset Ramp Time window.
This controls the transition time for the input,
output, and group faders when changing from one
preset to another. The range is Off to 30 seconds.
