* Plug the CAN hub into RaceCapture
* Plug the RJ45 cable into the CAN hub
* Plug the other end of the RJ45 cable into ShiftX3
* Prepare the RJ45 cable described below for power + ground and plug into the CAN hub


=====RJ45 power cable for ShiftX3=====
===Plug and Play connection===
* '''Note:''' ShiftX3 requires 12v power, via RaceCapture's own power connection.


Start by snipping the RJ45 connector off the end of a patch cable, and then expose the individual wires.
ShiftX3 connects effortlessly into our plug and play connector system, using the recommended cabling accessories:


If you just need power and ground, just use these connections and snip the others short.  
* [https://www.autosportlabs.com/product/can1-can2-dual-can-splitter/ Dual CAN splitter]
* [https://www.autosportlabs.com/product/can-bus-extension-cable/ CAN extension] (choose your desired length)
* [https://www.autosportlabs.com/product/inline-can-terminator/ Inline CAN terminator]


[[file:Rj45labeled.jpg|500px]]
Connect the Dual CAN splitter into the CAN1/CAN2 port of your main system:

'''Note:''' These color codes assume EIA-T568B RJ45 cable (check printing on the cable to confirm)
 
===CAN Termination===
CAN termination is enabled by default.  To disable termination, cut the '''CAN Term''' jumper on the bottom of ShiftX3.
 
==Powering and Connecting to RaceCapture==


=Scripts=
Then connect your CAN extension cable to the "B" port of the Dual CAN splitter:


The following scripts assume ShiftX3 is the first ShiftX3 on the bus (ADR1 jumper default setting). ShiftX3 is designed to work on the CAN2 network.
[[file:dual_CAN_splitter_closeup.jpg|600px]]
 
==Disco Lights Demo==
This is a test script that exercises all of the LEDs and the 7 segment display on ShiftX3. You can use this as a first time test, as it does not rely on any sensors.  


===Script===
At the opposite end of the CAN extension, attach the inline CAN terminator:
Copy and paste this entire script into the scripting window, replacing any existing script.


This script will randomly set LEDs with different colors, and the navigation buttons will cycle the display number up and down.  
[[file:inline_terminator_plugged_in.jpg|600px]]


<pre>
Finally, attach ShiftX3 to the other end of the Terminator to complete the installation.

end


function sxOnUpdate()
===Direct wire connection===
  for i=0,9,1 do
You can connect ShiftX3 into a non plug and play system by using the following cabling accessories:
    r = rndc()
    g = rndc()
    b = rndc()
sxSetLed(i,1,r,g,b,0)
  end
end


function sxOnBut(b, id)

  if b == 0 then return end
  if id == 1 then disp = disp + 1 end
  if id == 0 then disp = disp - 1 end
  sxSetDisplay(disp)
end


function sxOnInit()
Connect the pigtail wires to your system:
  print('sx onInit')
* Green to CAN2 High
end
* White to CAN2 Low
* Red to +12v (same power connection for your system)
* Black to Ground (same ground connection for your system)


--ShiftX3 library functions--
Then connect the pigtail to the inline CAN terminator.


function sxSetLed(i,l,r,g,b,f)

  sxTx(3,{bright,sxAutoBrightScaling,orientInverted})
end


function sxSetAlert(id,r,g,b,f)
==Navigation Buttons==
  sxTx(20,{id,r,g,b,f})
Once ShiftX3 is powered and connected via CAN bus, the left and right ShiftX3 buttons will automatically trigger corresponding left and right navigation actions on the RaceCapture dashboard.

Introduction

Parts in the Kit

  • ShiftX3

Shiftx3 3quarter.jpg

Compatibility

ShiftX3 is compatible with:

  • RaceCapture/Track MK2,MK3
  • RaceCapture/Pro MK2,MK3,MK4
  • RaceCapture/Apex
  • PodiumConnect MK1,MK2

Note: Not compatible with RaceCapture/Track MK1.

Firmware Requirements

ShiftX3 requires RaceCapture/PodiumConnect firmware 2.15.0 or higher. Download the latest firmware

Connection and Installation

Mounting ShiftX3

Attach ShiftX3 with #6 mounting screws and tighten until snug.

  • Note: You can install with the 7 segment display above or below the LED strip; see the setup instructions for selecting the orientation.

Dimensions

ShiftX3 enclosure dimensions.jpg

Plug and Play connection

  • Note: ShiftX3 requires 12v power, via RaceCapture's own power connection.

ShiftX3 connects effortlessly into our plug and play connector system, using the recommended cabling accessories:

Connect the Dual CAN splitter into the CAN1/CAN2 port of your main system:

Dual can splitter plugged in.jpg

Then connect your CAN extension cable to the "B" port of the Dual CAN splitter:

Dual CAN splitter closeup.jpg

At the opposite end of the CAN extension, attach the inline CAN terminator:

Inline terminator plugged in.jpg

Finally, attach ShiftX3 to the other end of the Terminator to complete the installation.

ShiftX3 with terminator.jpg

Direct wire connection

You can connect ShiftX3 into a non plug and play system by using the following cabling accessories:

Connect the pigtail wires to your system:

  • Green to CAN2 High
  • White to CAN2 Low
  • Red to +12v (same power connection for your system)
  • Black to Ground (same ground connection for your system)

Then connect the pigtail to the inline CAN terminator.

Finally, attach ShiftX3 to the other end of the Terminator to complete the installation.

Using ShiftX3

The LEDs and display on ShiftX3 are controlled by RaceCapture's Lua scripting capabilities. Built-in functions provide access to ShiftX3's capabilities. See the ShiftX3 Lua scripting reference for additional details.

Note: Ready to go scripts may be available as a preset. When in the Scripting view, press the Presets button to access a list of pre-configured scripts. Be sure to press the cloud update button to get the latest set of presets.

Lua scripting presets.png

Navigation Buttons

Once ShiftX3 is powered and connected via CAN bus, the left and right ShiftX3 buttons will automatically trigger corresponding left and right navigation actions on the RaceCapture dashboard.

[file:CSQfW4s.gif]

Disco Lights Demo

This is a test script that exercises all of the LEDs and the 7 segment display on ShiftX3. You can use this as a first time test, as it does not rely on any sensors.

Script

Available as a scripting preset - or you can copy and paste this entire script into the scripting window, replacing any existing script.

This script will randomly set LEDs with different colors and the display will update with random numbers. 

setTickRate(10)

function rndc()
  return math.random(0,255)
end

function onTick()
  for i=0,9,1 do
    sxSetLed(i,1,rndc(),rndc(),rndc(),0)
  end
  -- ascii characters between 0 and 9
  sxSetDisplay(0, math.random(0,9)) 
end

Sequential shift light + Gear indicator

This script configures just a sequential shift light, and update gear display.

Script (Gear is calculated from RPM and Speed)

Available as a scripting preset - or you can copy and paste this entire script into the scripting window, replacing any existing script.

  • Default is reading RPM from the channel named "RPM"
  • Default is creating the Gear channel with the channel name "Gear"
setTickRate(30)

-- Set ShiftX3 configuration parameters with default parameters
-- orientation: 0=normal, 1=inverted (display above LED bar)
-- brightness: 0-100%, 0 = auto brightness
-- can bus: 0=CAN1, 1=CAN2
sxSetConfig(0,0,1)

--create gear channel
gearId = addChannel("Gear", 10, 0, 0, 6)

--config shift light
sxCfgLinearGraph(0,0,0,7000) --left to right graph, smooth style, 0 - 7000 RPM range

sxSetLinearThresh(0,0,3000,0,255,0,0) --green at 3000 RPM
sxSetLinearThresh(1,0,5000,255,255,0,0) --yellow at 5000 RPM
sxSetLinearThresh(2,0,6000,255,0,0,10) --red+flash at 6000 RPM

function onTick()
  sxUpdateLinearGraph(getChannel("RPM"))

  -- calculate gear: tire diameter(cm), final gear ratio, individual gear ratios 1-6
  local gear = calcGear(62.7, 3.45, 4.23, 2.52, 1.66, 1.22, 1.0, 0.8)
  setChannel(gearId, gear)
  sxSetDisplay(0, gear)
end

Script (Gear is provided by an existing channel)

Available as a scripting preset - or you can copy and paste this entire script into the scripting window, replacing any existing script.

  • Default is reading RPM from the channel named "RPM"
  • Default is reading the Gear channel with the channel name "Gear"
setTickRate(30)

-- Set ShiftX3 configuration parameters with default parameters
-- orientation: 0=normal, 1=inverted (display above LED bar)
-- brightness: 0-100%, 0 = auto brightness
-- can bus: 0=CAN1, 1=CAN2
sxSetConfig(0,0,1)

--config shift light
sxCfgLinearGraph(0,0,0,7000) --left to right graph, smooth style, 0 - 7000 RPM range

sxSetLinearThresh(0,0,3000,0,255,0,0) --green at 3000 RPM
sxSetLinearThresh(1,0,5000,255,255,0,0) --yellow at 5000 RPM
sxSetLinearThresh(2,0,6000,255,0,0,10) --red+flash at 6000 RPM

function onTick()
  sxUpdateLinearGraph(getChannel("RPM"))
  sxSetDisplay(0, getChannel("Gear"))
end

Shift Light + Twin Alert + Gear Example (Gear calculated by RPM and Speed)

This script shows a more complete example that demos a sequential shift light + two alerts + Gear indicator.

Available as a scripting preset - or you can copy and paste this entire script into the scripting window, replacing any existing script.

Assumptions:

  • Engine Temperature on the 1st alert LED, connected to first analog channel - channel name "EngineTemp"
  • Oil Pressure on the 2nd alert LED, connected to second analog channel - channel name "OilPress"
  • Gear channel already exists, named "Gear"

Edit the script to change the analog channels you want to monitor.

Shift Light + Twin Alert + Gear Example (Existing gear channel provided by ECU)

This script shows a more complete example that demos a sequential shift light + two alerts.

Available as a scripting preset - or you can copy and paste this entire script into the scripting window, replacing any existing script.

Assumptions:

  • Engine Temperature on the 1st alert LED, connected to first analog channel - channel name "EngineTemp"
  • Oil Pressure on the 2nd alert LED, connected to second analog channel - channel name "OilPress"
  • Gear channel already exists (provided by ECU) and is named "Gear"

Edit the script to change the analog channels you want to monitor.

Predictive Lap Timer Indicator

This script enables predictive lap time visualization.

How it works

A bar extends left or right from the center of the linear graph:

  • Green bar extending to the right indicates you're beating the best time
  • Red bar extending to the left means you're falling behind.
  • When you're close to the best time, the center blue LED illuminates.


Notes:

  • The script is designed for a +/- 10 second maximum delta - so if you're ahead or behind by 10 seconds, the linear graph will be fully illuminated center-right, or center-left.
  • You will need to complete a a full lap to train the predictive timer before the graph will update.

Boost Gauge

This script visualizes a single analog input channel on the linear graph.

How it works

The script configures the linear graph, then reads an analog channel and updates the graph with the current value. In this case, the value represents boost level measured from a MAP sensor.

Assumptions

  • MAP sensor is on the channel named "MAP"

ShiftX3 CAN bus API

Overview

The CAN bus API provides the configuration and control interface for ShiftX3.

Two styles of control are available:

  • Low level control of LEDs - the ability to discretely set LED color and flash behavior
  • High level control - configuring alert thresholds and linear graph up front, and then providing simple value updates

Hardware / CAN configuration

CAN Termination

CAN termination is disabled by default. To enable termination, bridge the CAN Term jumper on the bottom of the ShiftX3 circuit board.

CAN Base Address

The default CAN base address is 931328 (0xE3600). You can change it by breaking the trace bridging the ADR1 jumper on the bottom of the ShiftX3 circuit board.

ShiftX3 CAN bus base address setting
ADR1 jumper setting Base address
Closed (Default setting) 931328 (0xE3600)
Open 931584 (0xE3700)

CAN Baud Rate

The default CAN baud rate is 1MB. You can switch to 500K by breaking the ADR2 Jumper on the bottom of the ShiftX3 board.

ShiftX3 CAN baud rate setting
ADR2 jumper setting Baud Rate
Closed (Default setting) 1MB

ShiftX3 CAN Protocol

Configuration / Runtime Options

Set Configuration Parameters Group 1

Sets various configuration options.

CAN ID: Base + 3

Offset What Value
0 Brightness 0 - 100; 1 = dimmest; 100 = brightest; 0 = automatic brightness control using built-in light sensor.
1 Automatic brightness scaling (Optional) 0-255; default=61. adjust this value to adjust the relative gain of the built-in light sensor when in automatic brightness mode.
2 Display orientation 0: 7-segment display is below shift light; 1: 7-segment display is above shift light

Set Display

Directly sets the value of the 7 segment display.

CAN ID: Base + 50

Offset What Value
0 Digit index 0 (must be 0)
1 Character ASCII value of character to display

The value of the display is set by the ASCII coded value. To set a numeric value, offset the value by 48: e.g. 48 = 0, 49 = 1, etc.

Most alphanumeric characters are supported as well, also via ASCII representation.

Set Discrete LED

A low level function to directly set any LED on the device.

CAN ID: Base + 10

Offset What Value
0 LED index 0 -> # of LEDs on device
1 Number of LEDs to set 0 -> # of LEDs on device (0 = set all remaining)
2 Red 0 - 255
3 Green 0 - 255
4 Blue 0 - 255
5 Flash 0-10Hz (0 = full on)

Alert Indicators

Alert Indicators are typically single LEDs or a group of LEDs treated as one logical unit. This is defined by the hardware configuration of the device.

Set Alert

Directly set an alert indicator

CAN ID: Base + 20

Offset What Value
0 Alert ID 0 -> # of Alert indicators
1 Red 0 - 255
2 Green 0 - 255
3 Blue 0 - 255
4 Flash 0-10Hz (0 = full on)

Set Alert Threshold

Configures an alert threshold. Up to 5 thresholds can be configured per alert indicator.

Notes:

  • If the current value is greater than the last threshold, then the last threshold is selected.
  • The first threshold may have a threshold value >= 0; remaining thresholds must be > 0

CAN ID: Base + 21

Offset What Value
0 Alert ID 0 -> # of Alert indicators
1 Threshold ID 0 - 4
2 Threshold (low byte)
3 Threshold (high byte)
4 Red 0 - 255
5 Green 0 - 255
6 Blue 0 - 255
7 Flash Hz 0 - 10 (0 = full on)

CAN ID: Base + 22

Offset What Value
0 Alert ID 0 -> # of Alert indicators
1 Value (low byte)
2 Value (high byte)

Linear Graph

The linear graph mode provides visualizations for common scenarios:

  • Sequential RPM shift light where the progression is stepped
  • Linear bar graph to linearly indicate a sensor value
  • Center left/right graph to indicate +/- performance against a reference - such as visualizing current predictive time vs best time

Power up default configuration

Upon power up the linear graph is configured:

  • Rendering style: left->right
  • Linear style: stepped
  • Low Range: 0
  • High Range: N/A
  • Threshold :
    • Threshold value: 3000 / segment length: 3 / color RGB: (0, 255, 0) / flash: 0
    • Threshold value: 5000 / segment length: 5 / color RGB: (0, 255, 255) / flash: 0
    • Threshold value: 7000 / segment length: 7 / color RGB: (255, 0, 0) / flash: 5

Configure Linear Graph

Configures the options for the linear graph portion of the device.

Rendering style:

  • If left->right, linear graph illuminates left to right
  • If centered, values below the mid-point in the range extend from the center to the left, and values above the mid-point extend from the center to the right.
  • If right->left, linear graph illuminates right to left

Linear style:

  • if smooth, graph length is updated smoothly by interpolating the current value in-between LEDs
  • If stepped, creates the visual effect of stepped progressions by setting the segment length of the threshold configuration. High Range of configuration is ignored.


CAN ID: Base + 40

Offset What Value
0 Rendering Style 0 = left->right, 1=center, 2=right->left
1 Linear Style 0 = Smooth / interpolated, 1 = stepped
2 Low Range (low byte)
3 Low Range (high byte)
4 High Range (low byte) (ignored if linear style = stepped)
5 High Range (high byte) (ignored if linear style = stepped)

Set Linear Graph Threshold

Configures a linear threshold. Up to 5 thresholds can be configured

Notes:

  • If the current value is greater than the last threshold, then the last threshold is selected.
  • The first threshold may have a threshold value >= 0; remaining thresholds must be > 0

CAN ID: Base + 41
