DM Series Controls and Features

DM1624F - 16 inputs, 24 outputs

Front Panels

The front panels of the DM Series include a USB port 

and LCD interface in addition to Power On/Off and other 

system controls.  The front panel controls can be locked 

out with special button presses to prevent tampering 

and inadvertent adjustments. (See 

Locking/Unlocking 

Front Panel Controls

.

The control interface is the same for all three models, 

since the difference between them is simply the number 

of inputs and outputs.

POWER On/Off Switch

The POWER On/OFF Switch is used to turn the DM 

unit on (1) or off (0).

LCD Interface

The LCD Interface is a  graphics type interface that can 

be used to set up and operate a DM system or provide 

feedback on system operation.

PUSH FOR MENU/SELECT Rotary Control

The PUSH FOR MENU/SELECT rotary control is used 

to select a menu, submenu or setup screen and for 

selecting or setting operating parameters.  This control 

is often used for minor tweaking after the original setup 

has been downloaded from a computer system via the 

USB port.

USB Port

Standard USB Version 1.1 connector for setup and con-

trol of the DM from a Windows-based computer system 

with USB interface.

Reserved Button

Currently used with the BACK Button to lock or unlock 

the front panel controls.

BACK Button

The BACK button is used to return to the previous 

screen or menu.

Item Select Buttons

The Item Select Buttons are used to select items from 

setup screens.
