Mackie DX810 Front Panel Lock, Upgrading the Software, Logic Inputs, Logic Outputs

unconnected or inactive, the logic voltage level is high (+5 V). The active state is defined as voltage low (0 V or ground).

The logic functions assigned to each individual logic input and output are configured using the DX-10E-PC application. In addition, each logic input and output can be assigned a descriptive name (up to 32 characters) for easier identification within the PC application.

Note: Logic I/O functions are set from the PC only.

Logic Inputs

A number of functions can be activated by the logic inputs:

Force-on/Force-off

This provides a means to temporarily increase or decrease the gain of a channel with an external switch. These are momentary functions and are active only when the logic input pin is active (held low). It affects a single input (only if the selected input has no priority assigned). This is defined when configured in the DX-10E-PC software application. It forces the input fader level to the fader on level or fader off level selected for that channel. See “Audio In” on page 22 for more information about the Force- on and Force-off function.

Mute

This function can be activated in one of three ways:

•Momentary: The mute function is continuously active while the logic input is continuously active.

•Latching: The mute function is activated or deactivated when the logic input goes from inactive to active. Mute activation or deactivation is specified during configuration.

•Toggling: The mute function will toggle its state when the logic input toggles between inactive and active.

Preset Recall

This function can be activated as a momentary function or as a latching function. When activated as a momentary function, the preset state is recalled only when the logic input is active. When the logic input is inactive, the DX810 returns to its base state as long as no other momentary function is in force. Normally, the base state is the state the DX810 was in prior to activating the preset state.

When activated as a latching function, the preset state is recalled when the logic input goes from inactive to active. See “Presets” on page 21 for more information about the preset recall function.

Logic Outputs

The logic outputs indicate the state of a number of different conditions.

Signal Present

A logic output can indicate whether a signal greater than –40 dB is present on an input or an output. Select the channel from the DX-10E-PC application.

Preset Active

A logic output can indicate when a particular

preset is active. Choose the preset to be indicated by the logic output from the DX-10E-PC application.

Priority Inactive

A logic output can indicate whether an Input Force-on Priority is active. This is selected from the DX-10E-PC application.

Front Panel Lock

The MODE button on the front panel is used to disable the front panel controls by selecting LOCK. The LOCK LED blinks for about five seconds before it engages. When the LED lights steadily, the front panel controls are disabled.

The Lock Code can be changed using the DX-10E-PC application (see page 20, "Set Lock Code"). To unlock the DX810 from the front panel, press the bottom "Down" buttons on the front panel in the correct numerical sequence. Use the following chart:

Input 1 Down = 1

Input 2 Down = 2

Input 3 Down = 3

Input 4 Down = 4

Input 5 Down = 5

Input 6 Down = 6

Input 7 Down = 7

Input 8 Down = 8

Low EQ Down = 9

Hi EQ Down = 0

Note: The default Lock Code is "1234."

Upgrading the Software

From time to time, Mackie Industrial will release upgrades for the internal operating software in the DX810. This can be downloaded from our website (www.mackieindustrial.com) to a PC-compatible computer. Use the serial port on the computer to connect to the COMM PORT on the DX810. Then transfer the data to the on-board flash memory with the DX-10E-PC software.
