USB InterfaceUSB Setup Instructions:

1. Install USB to Serial Driver

Located in the Help file of the Movi™ and Movi™ Pro DMG is the FTDI (USB to serial) driver. Click the applicable version for your operating system. Mountain Lion (10.8) users may use the version that states 10.7. You may also download the current driver from: www.ftdichip.com/Drivers/VCP.htm.

2. Locate OBD 2 Connector

Plug your OBD 2 USB hardware interface into the OBD 2 port ensuring a solid connection. OBD 2 connector locations vary by vehicle make. Please refer to service manual to locate your vehicle's OBD port.

3. Power Up

Turn on ignition switch to ON or start the vehicle.

4. Connect

Launch Movi™ and click "Yes" when asked if you are ready to connect.

 

USB InterfaceSerial Preferences: (USB and Bluetooth)

1. How do I know if my USB to serial driver is installed correctly?

  • Click here for assistance with installing serial drivers.

 

2. What should I select for Serial Port settings?

Bluetooth InterfaceOn "Automatic" Movi™ will cycle through all of the serial ports on your computer until either it finds the port that is connected to an OBD 2 interface or until the software runs out of ports to check. Once connected to a port, Movi™ will remember the connected port and try that port first the next time it connects. If a specific port is selected, Movi™ will only check that port for the interface. It may be faster to select the specific port versus waiting for the timeout in Automatic port cycling.

Serial Port Screen Shot

3. What should the Port Speed (bps) be set at?

The interfaces we currently ship require the 38400 (bps) setting.

4. What is Parity and what should Parity be set to?

Parity is a method for error detection in transmission. For most interfaces Parity should be set to "No Parity".

5. What is the "Timeout (sec)" selection in Movi™ʼs Preferences for?

The timeout is how long the software will wait before it gives up on hearing back from a serial port. Some vehicles respond more quickly, in which case the timeout should be set for a shorter duration so time is not wasted when troubleshooting connection issues. However, some vehicles respond more slowly, in which timeout should be set for a longer duration to ensure that Movi™ does not prematurely terminate communication.

Timeout Screen Shot

6. What is the Connection Keep Alive checkbox for?

Some interfaces, such as the Kiwi Wi-Fi interface, may lose their connection if left idle. With this checkbox checked, the software will automatically send a message every few seconds to keep the connection alive.
