This article will show you how to add channels to you Smart Dash configuration. Channels are the element that connects the data collected by Situne devices, and the actual data shown on the gauges in the app.

When the logger is enabled, all channels on the channel list are logged. 


  • Before starting the channel configuration, you must have added at least one device, an article on adding devices is here
  • The devices should be powered on and in range when channel configuration is done to keep the devices up to date with the current configuration.

Adding a new channel

To add a new channel to the channel list, start by touching the "Menu" button

Touch the "CHANNELS" option to bring up the Channel list

The Channel list shows all the channels currently configured in Smart Dash. All the channels shown here will be logged if the logger is enabled.

Predefined channels are channels that all DAH-280 units have on-board, this is released to GPS data and internal temperature + battery voltage. Predefined channels are exactly the same as a normal channel.

To add a new channel, start by touching the "Add new channel" cell, this will bring up the "Add New Channel screen" :

Channel Name

The channel name is what the channel will be called in log files, and also in Track Attack desktop app. All channel names are predefined, and cannot be altered. The number of predefined channels are over 260.

To set the Channel Name, touch the "Channel Name" line, this will bring up the "Channel Name Selector":

Since there is a lot of channels, a search function has been added. To use it touch the search field, this will bring up the keyboard and let you enter keywords for the channel you are trying to find. In our example below, we are adding the RPM channel and start entering "rpm" to find the correct channel.

When a suitable channel has been found, select it by touching the line, in our example we touch the "Engine RPM" line and this gets us back to the "Add channel screen":

Now we see that the Channel Name and the default unit has been entered.

Channel Unit

Channel unit is the default unit used by Track Attack, it has no effect other than to show what Track Attack will show it as, and also what it is shown as in the Channel List Live values. If you want to change it for whatever reason, it can be edited.


Before we can configure math on a channel, we need to select the source for the channel. Math is described further down in this page.

Source selection

The last section of the "Add New Channel" screen is the source selection. This is where you select where the data you want for the new channel to come from.

If you have a DAH-280 connected to your Smart Dash iOS app, you will have the DAH-280 internal sources. These are values that the unit produces internally, such as accelerometer data, GPS etc.

You will also have a set of Analog Inputs which are the 8 analog inputs that the DAH-280 has available. These inputs support a variety of sensors, including using them as 0-5v directly and also digital inputs, all this is configured when the source is selected.

Each CAN - BUS protocol will also have it's sources, this is shown below:

Here we have the DAH-280 configured with one CAN protocol "ECU Master Black" on CAN 1 and a "Situne EGT" unit connected to CAN 2.

Since we in this example have RPM input from the "ECU Master Black" we select the line containing the "CAN 1 ECU Master Black import" text. This will bring up the source list from this CAN bus protocol:

Scroll the list to find the source you want for this channel, in our example we touch the "Engine Revolutions Per Minute" line to select RPM.

This line will then be highlighted to make it easy to see what source is selected

After selection, touch the "Save" button in the upper right corner to save the selection. This will return you to the "Add Channel screen again.

The screen now shows in green what source the channel is connected to.

Math is now enabled.


After source selection we can enable math.

To use math slide the switch to the on position.

An arrow will appear on the end of the "Math" line, this shows that the math can be edited, to edit math variables please touch the "Math" line (not the switch). This will bring up the math configuration screen:

The math formula that is used is as follows:

(Value * Multiplication / Divisor) + Addition

Touch the value that you want to change, it is saved directly, and select back arrow to go back.

The channel is now configured and is saved by touching the "Save" button in the upper right corner.

This brings you back to the Channel List screen.

The new channel will now be shown with it's live value updated in the channel list.

Next step is adding a "Gauge" to visualize the values on the main screen, an article on this is here
