PCHUD

Data Capture

Mode 1 ALDL Data Tables Bar Graph and Binary Gauges Alarm Thresholds (High and Low) Optional Gauge Size and Colour Configurable Scaling and Decimal Places 100ms Sample Rate (Master Mode) 300ms Sample Rate (Slave Mode : VT)

PCHUD

Gauge Setup

1. Add Gauge Menu-->Gauge-->Add

Parameter Name (From *.PAR)

Location (Screen Position)

Type (Bar Graph, Binary, Warning)

Width & Height

Range (Defaults to *.PAR)

Alarm (High & Low Thresholds)

PCHUD

Gauge Setup

2. Gauge Colours Menu-->Setup-->Gauge Colours High Alarm, Low Alarm Colours

3. Remove Gauge Menu-->Gauge-->Remove

4. Modify Gauge Menu-->Gauge-->Modify (OR Double Click Gauge)

PCHUD

Gauge Setup

5. Save Screen Setup (*.HUD) Menu-->File-->Save e.g. VT_ENG.HUD

6. Retrieve Screen Setup (*.HUD) Menu-->File-->Open Last Used HUD File Opened On Startup

PCHUD

Sample Rate

Master Mode Sample Rate Menu-->Setup-->HUD Data Options-->Display Period Display Period = 100ms typ (Depends on Data Table) Make Sure : Timeout Period > Display Period

Slave Mode Sample Rate Sample Rate Depends on Vehicle Bus PCHUD Triggered by Tech1 Polling Message e.g. VT Commodore = 300ms polling rate

PCHUD

Data Logging

Two Types of Data Logging 1. Screen Capture (*.PLY) Records Visual Image on Screen Playback, FWD, REV, Pause, Step

2. Log to File (*.LOG) Logs Entire Mode 1 Message Data to File LOG.EXE to Display *.LOG File Displayed in Graph Format

PCHUD

1. Screen Capture

1. Record, Playback, Clear Buffer Buttons at Top of Screen Step Rev, Rev, Pause, Fwd, Step Fwd, Playback, Record, Clr Buf

2. Save Screen Capture (*.PLY) Menu-->Playback-->Save Playback

3. Retrieve Screen Capture (*.PLY) Menu-->Playback-->Open Playback

PCHUD

2. Log to File

1. Start Log to File Menu-->File-->Start Capture to File

2. Stop Log to File Menu-->File-->End Capture to File

3. Display Log Data (*.LOG) LOG.EXE

PCHUD

LOG.EXE

1. Load LOG File (*.LOG) Menu-->File-->Open

2. Setup Graph Menu-->Graph-->New (Select from list of parameters)

3. Save Graph (*.LLG) Menu-->Graph-->Save

4. Open Graph

Menu-->Graph-->Open

PCHUD

LOG.EXE

5. Remove Graph Menu-->Graph-->Select Graph Menu-->Graph-->Remove

6. Scale X Axis Menu-->Graph-->Modify X Select Manual Scale Adjust Min / Max Values

7. Scale Y Axis Menu-->Graph-->Modify Y Select Manual Scale Adjust Min / Max Values

8. Line Style Menu-->Graph-->Modify X Menu-->Graph-->Modify Y Line Scatter

PCHUD

LOG.EXE

9. Cursor Course Left : UP Arrow Course Right : DOWN Arrow Fine Left : LEFT Arrow Fine Right : RIGHT Arrow

10. View Menu-->View Single Overplot Separate (Arrange All)

11. Zoom Menu-->Zoom Start at Cursor End at Cursor In 2x Out 2x Center Out Max (Full Size)

12. Text Output (*.CSV) Menu-->File-->Export As Text

PCHUD

Data Slewing

ALDL Mode 4 Data Table Slew Outputs (Byte Variables) Slew Discretes (Bit Variables) Absolute Slew (Var = Slew) Delta Slew (Var = Var + Slew) Configurable Variable Names

PCHUD

Define Slew Parameters

1. Start New Slew Setup Menu-->Slew-->New

2. Edit Outputs (Byte Variables) Menu-->Slew-->Edit Outputs-->Edit Name : Displayed Parameter Name ID : Must match location in Mode 4 Data Table Units : Displayed Units Scale, Offset : Scaling Info From XDE or Software Min, Max : Range of Slew Data for this Parameter Places : Number of Decimal Places to Display

PCHUD

Define Slew Parameters

3. Edit Discretes (Bit Variables) Menu-->Slew-->Edit Discretes-->Edit Bit Number : Same order as Mode 4 Data 00 Bit Description : Displayed 揈 nable?Text 01 Bit Description : Displayed 揙 ff?Text 02 Bit Description : Displayed 揙 n?Text ID : Don 抰 Care

PCHUD

Define Slew Parameters

4. Save Slew File (*.SLW) Menu-->Slew-->Save

5. Open Slew File (*.SLW) Menu-->Slew-->Open e.g. VT.SLW

PCHUD

Slewing Variables

Slew Outputs (Byte Variable) Menu-->Slew-->Slew Outputs Up To 3 Parameters Enable Slew Message : Enables Mode 4 Communication Edit Button : Select Parameter Activate : Activates Slew Parameter Delta : Var = Var + Slew Absolute : Var = Slew

PCHUD

Slewing Variables

Slew Discretes Menu-->Slew-->Discrete Mode Control Up To 24 Discretes Enable Slew Message : Enables Mode 4 Communication Enable : Enables Slew Parameter 揙 n? : Sets Discrete State to ? 揙 ff? : Sets Discrete State to ?

PCHUD

Configuration

1. CSV File Contains all parameter information Edit Using Excel e.g. VT_ENG.CSV

2. PAR File Generated From CSV File Use CSV.BAT e.g. CSV VT_ENG (Don 抰 Include File Extension) Output is VT_ENG.PAR Errors in VT_ENG.TXT

PCHUD

Communication Setup

Comm Parameters Menu-->Setup-->Comm Setup Comm Port Baud Rate : 8192 Slew Device ID : VT = $F5 DTR High at Startup : Yes

PCHUD

Communication Setup

Master Mode Menu-->Setup-->Comm Protocol-->ALDL Master PCHUD Controls Comm Bus

Slave Mode Menu-->Setup-->Comm Protocol-->ALDL Slave PCHUD Triggered By TECH1 Poll Message

Sample Rate & Comm Timeout Menu-->Setup-->HUD Data Options Display Period (ms) : Only For Master Mode Timeout Period (ms) : Make Sure > Sample Period
