Default factory settings

The default settings of the MT will set the device in a configuration that calculates and outputs the orientation 100 times per second in quaternions. The MTData2 messages will also include a sample counter which can be used to detect missing samples. The data is transmitted at a baud rate of 115k2 bits per second and the synchronization in- and outputs are disabled.

The default settings are listed in the table States.

There are two ways to set the MT in this default setting. You can RestoreFactoryDef or you can use the individual messages shown in the table to (re)set the settings. Keep in mind that if you use the RestoreFactoryDef message, the filter / device settings shown in the table below are also reset.

Restore communication

If the MT has been programmed with a baud rate setting that is not compatible with software or is unknown to the user, a 'restore communication' procedure can be applied. This procedure will set a number of settings to its default values, including the baud rate. Note that for MTi RS422 devices, this procedure is the only method to set the MTi to default values in order to restore communication. For devices with both USB and serial interfaces (i.e. RS232 and RS485), you can easily restore communication by disconnecting and reconnecting over USB.

You can either use the MT Manager (Tools menu) or perform the procedure manually. To restore the settings, manually follow the following procedure:

1. Disconnect the MT from the USB-serial converter cable.

2. Insert the USB-serial converter cable into a free USB port and open the respective virtual COM port with the following settings: baud rate 115k2, 8 databits, no parity and 1 stop bit.

3. Start sending the byte value 222 (0xDE) repeatedly, but make sure there is a gap of 0.1 to 0.5 ms between the words (no back-to-back transfer).

4. While sending the message, connect the MT to the USB converter.

5. Stop sending when the WakeUp message is received.

This procedure during MT device WakeUp ensures that communication can always be restored with the device, even if erroneous settings have been programmed by accident.

Default communication settings

The baud rate (bps) setting can be changed by the user. The maximum is 921600 bps and the minimum is 4800 bps. Should the communication fail, it can be helpful to change the number of stop bits to 2.
