Smart Dash / Smart Dash Quick Start Guide
« Last post by oletorv on 28 August 2019, 10:32 »
This post relates to configuring the Smart Dash when you get it from Situne !

Prerequisites

  • Smart Dash Kit from Situne
  • iOS based device
  • Smart Dash application downloaded from the App Store or Test Flight
  • Bolts and nuts needed for HW installation
  • Hookup wire

Smart Dash Kit Contents
  • DAH-280 Data Aquistion Hub with 8 analog inputs
  • LEDBar LED based warning indicator
  • Connector housing and pins
  • Pinout drawing

If any of these items are missing, please contact Situne as quickly as possible and we will send you the missing items.

Hardware installation
This section describes how to do the hardware installation.

When starting the hardware installation it's best to plan before starting :
  • Where is the DAH280 going to be fitted ?
  • Where are you going to power the DAH280 from ?
  • What analog inputs are going to be used (if any) ?
  • How is the CAN connection going to be done (if used) ?


1. Where is the DAH-280 going to be fitted ?
When placing the DAH-280  in the vehicle, remember to try to place it as close to the physical center of the vehicle as possible.
Do not place Smart Dash in the engine compartment !
The best place is on top of the transmission tunnel.


The DAH280 has two mounting holes, one on each side, use these to mount it firmly to the chassis of the vehicle. In places with extreme vibration please use some kind of damping to keep from transferring high levels of vibration into the unit.

Orientation of the DAH-280 should be mounted so the connector points to the rear of the vehicle and label faces up



2.Where are you going to power the DAH280 from ?



The DAH280 needs to be powered from the 12V battery of the vehicle.
It is important to use a 5A fuse either in the fuse box, or inline. If using an electronic fuse box, program the fuse to 5A.

Use minimum 1.0mm2 wire to connect 12V and GND wiring to get a good connection on the large pins.

GND should be connected to pin A2 with a large pin.
+12V should be connected to pin A1 with a large pin.



3.What analog inputs are going to be used (if any) ?

The DAH280 can handle up to 8 analog sensors connected directly to the unit. The inputs can handle both temperature sensors and 0-5V analog sensors.

Temperature sensor hookup:
      Temperature sensors have two pins, which pins are connected to Sensor GND and which are connected to the analog input.
      DAH280 contains two sensor ground pins A7 and B7, we recommend using A7 for analog channel 1-4 and B7 for analog channel 5-8
      GND wires should be split in the wiring harness you are making at appropriate points.

Analog 0-5V sensor hookup:
      Analog sensors have three connections:
     
  • GND - Connect to one of the sensor ground pins
  • +5V - Connect to one of the +5V reference pins A6 or B6 (use A6 for sensors connected to analog inputs 1-4 and B6 for analog inputs 5-8
  • Signal - Connect to the analog input pin
     
4.How is the CAN connection going to be done (if used) ?
DAH280 has two CAN-buses, CAN1 is used for connection to your ECU, CAN2 is used for connection to other Situne units.
Connection of the CAN1 bus to the ecu is done with two wires C6 CAN1_L and C7 CAN1_H.
The wires used shall be twisted together. Use a drill to twist the wires together.
     
CAN-bus termination:
A CAN-bus needs to be terminated, this is done with one 120Ohm termination resistor in each end of the bus wires.
Some ECUs have a termination resistor built in while others have software controlled termination resistors.
DAH280 has a built in 120Ohm resistor that can be enabled/disabled by the Smart Dash application.

RPM-input hookup:
DAH280 has one digital input for RPM signal. Most ECUs of today has CAN bus, and the RPM then be transmitted through the CAN bus.
In a setup with an ECU that does not have CAN, the ECU will have a tachometer output which can be connected to DAH280.
Another scenario is when not using an ECU, then the RPM-input should be hooked up either to the ignition module, of to the coil low voltage side to get RPM into Smart Dash


The Smart Dash is now hooked up and ready to be paired and configured with the Smart Dash iOS application !


Smart Dash app installation
The Smart Dash app is currently in Test Flight beta program.

The current URL for testers is: https://testflight.apple.com/join/tsyn6ZnZ

Click the link with your iOS device, and it will open up the app store and help you install the Apple Test Flight application that in turn installs the Smart Dash application.



Inside the test flight application click on the Smart Dash application and click install



Then click on "Open" to start the Smart Dash application



You will then see the main screen of the application:



Description of the main screen:



The main screen is comprised of a main tile space and a menu and indication field in the upper left corner.

Menu button has three functions:
  • LOG - Configuration and access to all log files etc.
  • GAUGES - Configuration of the tiles shown on the screen
  • SETUP - General and device specific setup

Logging indicator: The logging indicator show the current status of logging of data on the iOS device:
  • Green indicates data from DAH280  is currently being stored
  • Orange indicates data from DAH280  is in after-run still being stored
  • Black indicates data from DAH280 is not being stored

Data indicator: Indicates that the iOS device is receiving data over the bluetooth interface:
  • Black - No data is coming from DAH280
  • Green - Data is streaming from DAH280

This article is a Work In Progress, stay tuned

Smart Dash / Smart Dash App CAN-Bus Setup [Howto]
« Last post by oletorv on 12 August 2019, 13:10 »
In this post we will go in depth on setting up the DAH-280's CAN-Bus from the Smart Dash iOS App.


Prerequisites:
  • DAH-280 connected to +12V and GND of the vehicle and powered up
  • CAN-Bus lines connected to CAN-Bus lines of the ECU in the vehicle
  • Unit has been added to the phone app (See separate howto post)

CAN-Bus setup

On the main screen of the app select menu button:



Then select the setup option:



Then select the your device from the list:



The DAH-280 settings menu will then be shown, the CAN-Bus #1 is the options at the top



The first thing one needs to setup is whether or not the electronic termination should be on or off, touch the button to turn on or off termination:



The next thing we need to configure is the protocol which the ECU communicates. This is selected by touching the CAN1 Protocol option:



Then scroll through the options to select the protocol you want to use, and touch "Select":



The CAN-Bus protocols implemented by 12.08.2019 are:
  • Not Used - CAN-Bus #1 not used
  • EFI Euro 8 (Situne Setup) - Protocol used for EFI Euro 8 setup with Situne's custom protocol, also used for Link 4G+ ECUs setup with custom streams
  • Megasquirt 3 Dash Protocol - Setting used with MS3 setup with dash protocol enabled
  • Motec M1 Series Stream - Protocol used by Motec M1 Series setup with Basic CAN Stream
  • ECU Master EMU Protocol - ECU Master's custom protocol used on EMU Black and other ECUs
  • Haltech V1 Protocol - Haltech CAN based ECU protocol
  • AEM - AEM ECU's running with extended CAN-Bus addresses
  • Emtron Predefined 1 - Emtron based ECU's setup to transmit Emtron Predefined message set #1

After this the CAN-Bus #1 Speed must be setup :



Select the correct speed from the list and touch "Select":



The CAN #1 Channel list will now appear, and let you select which channels should be uploaded to Track Attack.

After this step the CAN-Bus #1 setup is complete, touch the Save button to write CAN-Bus #1 configuration into DAH-280:

Smart Dash / Smart Dash Wiring Guide (Work in Progress)
« Last post by oletorv on 24 July 2019, 22:01 »
Pinout of the Smart Dash DAH-280 is shared here in a google document:

https://docs.google.com/spreadsheets/d/1JcwrZuBmyZyXYH9qavSpqWRqof7tmU6Gfk4IxvpxF5Q/edit?usp=sharing


Most common wiring types are as follows:


1. CAN-Bus based ECU no analog sensors

ECUs with CAN-Bus interfaces can be wired directly to the DAH-280. The CAN-BUS uses two wires for communication: CAN_L and CAN_H, these wires are routed directly to the respective wires on the DAH-280 (CAN_H (C7), CAN_L (C6)). For the CAN-Bus to communicate properly the bus needs to be terminated correctly. The correct is to terminate in each end of the bus wire with 120 Ohms. The DAH-280 includes SW selectable termination, this means that you can easily turn on and off the termination resistor inside the DAH-280 with the smart phone application. Go into the Setup menu and select your device, then turn on the switch for CAN1 termination to enable the termination resistor. Touch the Save button in the upper right corner to write to the DAH-280, and termination is enabled.

When using the DAH-280 with a CAN-Bus based ECU, the protocol for the ECU must be selected.
Situne implements the most commonly used aftermarket ECUs and also some OEM ECUs where we have had them available. If you need support for a ECU that is not implemented at the moment, please e-mail us or use our contact form to request implementation of your ECU's protocol.

The wiring when using only CAN-Bus is pretty simple. What you need to connect are:
  • A1 +12V supply. Connect to ignition sw via 5A fuse
  • B1 GND supply. Connect to chassis
  • C6 CAN1_L (CAN1 Bus low wire) Connect to ECU CAN_L
  • C7 CAN1_H (CAN1 Bus high wire)Connect to ECU CAN_H

Configuring the DAH-280 is as simple as opening the app and going into Setup and selecting your unit and setup the following parameters:
  • CAN Bus 1 Speed (Set speed to match your ECU CAN-Bus Speed
  • CAN Bus 1 Protocol. (Set protocol to match your ECUs type
  • CAN Bus 1 Termination. (Set termination based on your wiring, more on this in a later post)

2. Non CAN-BUS ECU, analog sensors connected to DAH-280

Some old aftermarket, or OEM ECUs do not support CAN-Bus, which means that one will need to hook up analog sensors for the parameters you want to monitor. The DAH-280 has 8 analog channels, these can be configured through the smart phone application to be 0-5V analog inputs or NTC thermistor inputs (for all analog temperature sensors). As of this writing, only Situne Sensors are supported, but there will be possible to use custom sensors in the future. The DAH-280 has two +5V analog sensor supplies, these can be shared on mutiple sensors, normal configuration is that channel 1 through 4 share one +5V and one sensor GND and channels 5 through 8 share the other +5V supply and sensor GND. This is the recommended configuration.

We will post a new thread with screenshots on how you configure the analog channels through the smart phone application, it is pretty simple :)

3. ECU with CAN and supplemental sensors connected to analog channels

This is the most advanced configuration, and are used by some of our customers which either have parameters they want to monitor, but the sensors are not available through the ECU CAN-Bus interface. This is a combination of the two configurations listed earlier in this post.
