## AVIT Data Recorder Instructions

Getting C

onnected There are two method of connecting to the AVIT. 1) Wired. The AVIT and PC must be connected using a crossover Ethernet cable. PC I P configuration must be set to “Obtain I P address automatically ”. This is the best and easiest way

to connect to the AVIT. 2) Wireless. Wireless internet can be used to connect to the AVIT. The computer must be able to communicate with an ad

- hoc 802.11b network. Once the AVIT is powered, yo u can scan for wireless networks . Select the wireless network corresponding to the AVIT and connect. Once the network is connected, and an IP address has been negotiated, the AVIT is available for use. 

### Setup In order to use the AVIT as a Data Recorder, some software must be installed. All of the Allison Engineering tools have a Communication Interface dialog as follows.

### AVIT Software

In order to install the data recorder software, first y ou must establish a connection (see Getting Connected section). Once the connection is es tablished, the data recorder software can be installed by clicking on the “update AVIT recorder software” button. The installation can take several minutes. Follow the on screen instructions to complete installation. 

### AVIT Firmware After completing a c ontrol s fill up and on new AVIT’s there may be a need to install the latest firmware . This can be installed by clicking on the “update AVIT firmware” button. If the firmware is installed y ou must follow by installing the AVIT software. 

### Set Files In ord er to collect data with the Data recorder, a datalog set file must be installed into the AVIT similar to Datalog for Windows. The set file for the AVIT uses the same set file format as Datalog for Windows (see Datalog Help, Modify ing a Setup). 

### Compilin g the AVIT Set File The AVIT requires that the set file be precompiled for a specific TCM software level. The AVIT does not have the X ref’s available to convert variable names to addresses for any TCM software level, and any variable names that exist in the set file must be converted to address locations. However, address locations in the TCM software can change between software levels, thus a precompiled set file is only valid for one software level. Update: As of Windows Datalog version 21.92, the I nstall PDR Setup also compiles the set file for AVIT use. There is no Make AVIT Setup option on the Tools menu. To compile and load a set file: Open datalog and click on Tools, a drop down list will open, click on AVIT Data Recorder.This will ope n the AVIT data recorder dialog box

.Click on Install Setup.

Datalog will prompt y ou for a set file: Browse to find the set file y ou want to load. Notice: the set file should be located in dl/sets folder for the file to properly load. It is not possible to load a set file from y our desktop or any other file folder.Note: Do not try to load a set file that has alread y been compiled! A compiled set file will have the software level append ed into the name of the set file. Example

- Recorder file 1 8EC .set These compiled set files are saved in dl/avit folder. Itis possible to load a compiled file , but the AVIT will not record properl y.

Ty pe in the proper software level for the TCM yo u want to record AVIT data from or b rowse :

Click OKOnce this is complete, Datalog will save the compiled set file in c: \ gen4 \ dl \ avit\

. The set file will be loaded into the AVIT recorder. Inorder to make sure that the AVIT is actually collecting data, observe the lower left status p anel. Once collection has begun, it will update to show the set file name, and give the status of the buffer. This panel is not updated often, and it can take up to 10 minutes to show the status.

Notice : Datalog has appended the software level ont o the name of the set file. This set file cannot be load ed a second time because it has alread y been compiled.

### Working with the Data Recorder

In order to interact with the Data Recorder, y ou must launch the AVIT Data Recorder dialog window. In Data log, on the tools menu, click on the AVIT Data Recorder option.

Once this is launched, and y ou are successfull y connected to an AVIT Data Recorder, The AVIT Data Recorder dialog window will appear.

### Using an external switch to trigger

It is possible to use an external shift save box to trigger a data save. The switch box will have three LED’s used to determine the current status of the AVIT. The switch is connected to the AVIT at the 25pin parallel port connection. Green

– Indicates that a set fil e is loaded and the buffer is recording data

-- the switch is read y to be pushed to save data. Orange

– Flashes when the switch has been triggered, indicating data is being saved. Red

- The red LED indicates that there is an active code present.

### Con figuring a set file for external switch See the example

- This set file configuration will allow data to be saved 30 seconds prior to the switch trigger and 10 seconds after, these timing variables can be an y value if the buffer is large enough. This in formation must be added to the set file store control section. Store Control: On Start When: EXTSW Delay : - 30 Save When: EXTSW Delay :10.0 In itialState: Stopped end:
Set - up to set on a DTC shown below: **Set up to trigger on a DTC ---**  Store Control:On Start W hen: P_Code<>P_Code Delay:
- 20 Save W hen: P_Code<>P_Code Delay:10.0 Initial State: stopped end:

### Wiring an external T her misto r A thermistor can be used to collect converter out temperatures with an A42 or A43 TCM. A jumper wire can be incorporated at the TCM gro und return pin 58 to provide a ground for the thermistor . The other side of the ther mistor wiring should run to TCM pin 75

. You will need to add a line in the set file like this

- Thermisto r available from Signal & Power

– P/N 12160855

- B Datalog line used : C=D Conv_Out_øC A=@VfVIOS_T_RetarderUndfltd B=2 E=N/128: U=øC P=N Z=3 S=20 L=7 T=Y DASH=N P_ALT=N 

### Saving files File s are saved on the AVIT data recorder with Dat alog store control blocks. See the Save When: statements under Datalog Help: Modifying a Setup. 

### Retrieving DL4 Files with Datalog Data files, DL4 files, can be retrieved from the AVIT Data Recorder dialog window. The list box in the upper rig ht corner of the AVIT Data Recorder dialog window shows the files that are on the AVIT. They can be retrieved b y clicking Save All Files, or b y selecting the files to save and clicking Save Selected Files. 

### Retrieving DL4 Files without Datalog Data files can be retrieved by mounting a network drive to the AVIT. This should onl y be done if you are going to be downloading a lot of files, or if the files are to be retrieved b y a remote user who does not have Windows Datalog. **AVIT Data Recorder Software ver**  **sion 1.1.4**  **or newer automatically enables**  **File Sharing.**First, the AVIT must be configured to allow File Sharing. Once connected wired or wirelessl y to the AVIT, open a web browser. If wired, go to h ttp://192.168.43.101/ , or if wireless go to http://172.16.1.1/ . On the left, click on Boot Options.

When prompted for a username and password, Username: root Password: powerful Then scroll down until you see the Services section, and the File Server option. Change the drop down menu to Enabled. Then scroll to the bottom of the screen, and click Save Settings.Then click on Reboot CarDAQ

- AVI T Now. Allow AVIT to reboot. Wait until the AVIT is showing both y el low lights.Once this is complete, open Windows Explorer or My Computer. On the Tools menu, click on Map Network Drive. Pick an y available Drive, then in folder, if connected wired t ype in \\ 192.168 .43.101 \ Share \ cf \ data , or if wireless, \\ 172.16.1.1 \ Share \ cf

\data . Then click on Connect using a different user name. Username: root Passwrod:powerful Click Ok, then click Finish. A new drive should ap pear in Windows Explorer or My Computer. Files can then be manipulated as normal.

### GPS GPS can be used on the AVIT. The recommended GPS receiver is the Garmin GPS 18 with the serial and cigarette lighter power adapter. An y GPS receiver can be used, as long as it has a 9 pin serial connection and can be configured to send GPS data in the NMEA format, at 4800 bps. A null modem adapter may be needed to mate the GPS cable with the AVIT connector. GPS use requires AVIT Data Recorder Software version 1.1

. 4 or later. This version automatically sets up the AVIT to collect GPS data. Add GPS data to your set file and it will be collected provided there is a GPS receiver plugged in, and the GPS receiver is collecting data from satellites. 

### Date and Time GPS or Cellular broadband is required to have a valid date and time set in the AVIT. A valid date will also be set once the AVIT is connected to Datalog, and the date will remain until the AVIT is power cy cled. At this point, the date will be reset to January 1, 1970. If the date and time is not set, the files saved by the AVIT Data Recorder will have a date close to January

1, 1970. All other functions will operate normall y. 

### Ignition Wakeup The AVIT is set to automatically to collect data on power up once a set file has been installed. In order to disable this, click on the Disable Collection button in the AVIT Data Recorder dialog window. The AVIT will automatically go to sleep after 2 hours of try ing to connect to the TCM, or 2 hours after any of the Allison Engineering Tools has been connected to the AVIT. This will prevent the AVIT from draining the vehicle battery once ignition has been shut off. In order to wake up the AVIT, either power cy cle the AVIT, or provide an ignition sense into the re d banana jack on the front of the AVIT. Once ignition sense is raised above 5 volts, the AVIT will wakeup, and resume collection. AVIT wakeup is much quicker then power up.

### Cellular Broadband

Cellular Broadband can be used with the AVIT. The only device that is currentl y supported is the Novatel U720 USB EV

- DO modem on the Verizon network.

Other USB EV

- DO modems will work, please contact Rob Carlson ( robert.carlson@allisontransmission.com ). The cellular broadband card allows data to be uploaded to an FTP server. Data is automatically moved to a network drive inside the firewa ll.

### Troubleshooting

If communication cannot be established with the AVIT perform these steps in order to regain communication. 1) Power cy cle the AVIT. Retry

. 2) Reboot the laptop. Retry. 3) If the PC cannot connect to the AVIT’s Ethernet, ensure that the IP settings are set to “Obtain I P Address automatically ”. Ensure you are using a crossover Ethernet cable between the PC and AVIT. Contact your Computer Support Desk. 4) If the PC cannot connect to the AVIT’s wireless network, ensure that the PC is allo wed to make network connections with Ad

- Hoc networks, and he IP settings are set to “Obtain I P Address automaticall y”. Contact your Computer Support Desk or try

using a wire. 5) If you have a valid Ethernet or wireless connection to the AVIT and can communic ate to a TCM/vehicle using the Allison Engineering Tools but cannot establish communication to the AVIT Data Recorder, reinstall the AVIT Data Recorder software. This will not loose any files previously

saved , but it will return the AVIT Data Recorder to its default state with no set file installed. 1) A crossover Ethernet cable must be used to communicate with the AVIT. If there is a repeatable problem with the AVIT that is not related to Ethernet or wireless connection issues, please contact me at Robert.Carlson@allisontransmission.com
