You can easily send Hex values in a BrightSign Author presentation that is set to **Advanced**. For example, this is a "power on" command for a ViewSonic projector. These are hex values, indicated by the `0x` prefix. 

`0x06 0x14 0x00 0x04 0x00 0x34 0x11 0x00 0x00 0x5D`

To send this command to the projector using the serial port on a BrightSign player:

# Media State

::::VerticalSplit{layout="middle"}
:::VerticalSplitItem
1. Create an **Advanced** presentation.
2. Select the media state where you want to send the Hex command.
3. Go to **State Properties > Advanced**.
4. Add an **Entry Command** or **Exit Command** and set the C**ommand** to **Send** and the **Parameters** to **Serial bytes (comma separated)**.
5. Set the **Port** to 0 (this is the case for most standard serial devices).
6. Enter the command in the **Byte** field. Use a comma to separate each byte.

When sending serial bytes, you must use decimal values, not the Hex values listed above. For example:

Hex values: `06 00 04 00 34 11 00 00 5D`
Equivalent decimal values: `06 00 04 00 52 17 00 00 93`

You can convert Hex values to decimal values using any number of free websites.
