:::hint{type="warning"}
This page / section pertains to **BrightAuthor Classic**, our legacy app. **BrightSign Author **is our latest app for managing content and players.

Development of BrightAuthor Classic has largely ceased and the app will eventually be deprecated and replaced with BrightSign Author.
:::

Use the **Interactive** tab to configure settings for serial, USB, and UDP communications.

# Serial 

Use this section to configure serial port communications:

- **Port**: Select a serial port to configure. Most standard serial devices enumerate on port 0 (on the HO523, they will enumerate on port 1).

:::hint{type="warning"}
A USB-serial device (such as a GPS receiver) will enumerate on port 2. Additional USB-serial devices will enumerate on ports 3, 4, 5, etc. The enumeration order will remain consistent between reboots as long as the USB-serial devices are connected to the same player/hub ports. The enumeration order can be retrieved using the "usblist" command at the `brightsign>` [shell prompt](docId\:YWkSi6X-2hez1BwztfHMP); otherwise, it will need to be determined by testing the setup.
:::

- **GPS Receiver**: Check this box if the port is being used to connect a USB-serial GPS device to the player.
- **Baud rate**: Set the baud rate for serial communications on the port.
- **Data bits**: Set the number of data bits.
- **Parity**: Set the parity.
- **Stop bits**: Select the number of stop bits.
- **Protocol**: Determine whether the serial data is formatted as **Binary** or **ASCII**.
- **Send EOL**: Select the end-of-line character when sending data to a serial device.
- **Receive EOL**. Select the end-of-line character when receiving data from a serial device.
- **Invert Signals**: Check this box to invert the TX/RX signal levels on the serial port. This allows the player to communicate with devices that use -12V to 12V signaling. Inversion is only supported on the following ports: The DE9 and USB ports on the 4Kx42, XDx32, HDx22, XDx30, and HDx20, as well as the 3.5mm serial port on the XTx43/XDx33 (units that are rev H or earlier) and HDx23. Except for the 4Kx42, all of these ports perform 5V signaling.

# UDP

Use this section to configure UDP communications:

- **UDP Destination Address**: Specify where UDP commands generated by the presentation should be sent:
  - **Specific IP Address**: Enter a single destination IP address in dotted quad form.
  - **All devices on the local subnet**: Select this option to broadcast UDP messages to all devices on the local subnet.
- **UDP Destination Port** : Specify the destination port for UDP messages generated by the presentation.
- **UDP Receiver Port**: Specify the port used by the player to receive UDP messages (for triggering [UDP Input](docId\:uy5vXEVZ_p8RE2QtJvOd0) events on the player).

# Synchronization 

Check the **Enable enhanced synchronization** box to use a player synchronization scheme similar to the BrightWall™ feature. When this feature is enabled, interactive presentations using [Synchronize](docId:6SGmDHW0CN4tRt8wKERb4) events can be easily linked via a Genlock leader/follower scheme: The presentation sending a [Synchronize](docId\:lG8iLYdnIB0PL8tvxTKBo) command acts as the leader, while the presentation(s) using Synchronize events act as followers. Synchronize events associated with follower presentations will trigger within a millisecond of the Synchronize command associated with the leader presentation.

- **Master**: Select this option to have the presentation send Synchronize commands. A leader/master presentation cannot contain Synchronize events (i.e. you cannot chain one leader presentation to another).
- **Slave**: Select this option to have the presentation receive Synchronize commands (via Synchronize events).
- **Domain**: Enter a domain number between 0 and 127. This number needs to be unique for each set of leader/follower presentations on the local network. This will ensure that multiple groups of synchronized presentations can operate on the same local network without synchronization messages interfering with each other.

# Touch

Use this section to configure Rectangular Touch events:

- **Cursor**: Select a mouse display option for Rectangular Touch events:
- **Always hide cursor**: The mouse cursor will never appear with Rectangular Touch events.
- **Always display cursor**: The mouse cursor will always appear with Rectangular Touch events
- **Auto display cursor**: The mouse cursor will be present only if there is more than one touch region on the screen.
- **Flip coordinates**: Check this box to reverse the coordinates of the touchscreen input.
