Figure 131. Sample Mouse Down String
4. (Optional) Type a Mouse Up string. This is the command that is sent to the serial output device when an operator releases the custom
button. Leave this field blank if you do not want a command sent when the button is released.
5. Click OK. The Edit Button dialog box closes.

ASCII COMMAND SPECIAL CHARACTERS

If a command contains unprintable characters, replace each unprintable character with its three-digit ASCII code between angle brackets. For
example, the command BLACK-HOT<Carriage Return> is represented in VMX300(-E) as BLACK-HOT<013>. Note that ASCII codes must be three
digits in length. Add leading zeroes, if an ASCII code contains less that three digits.
If a command contains single or double quotation marks, replace the quotation marks with their ASCII codes: <039> for a single quotation mark
and <034> for a double quotation mark.
Other useful ASCII codes for unprintable characters are <002> for the Start of Text (STX) character and <003> for the End of Text (ETX) character.

Delete a Custom Button

Click the custom button name in the list of buttons, and then click Delete. The button is removed from the list.
To delete more than one custom button at a time, select the buttons you want to delete and then click Delete. To select buttons that appear
consecutively in the list, click the first button, and then press the Shift key and click the last button. To select buttons that are not consecutive,
press the Ctrl key while clicking the buttons.
LIMITATIONS OF CONTROLLING A SERIAL OUTPUT DEVICE
Note that you cannot control a device under two different device drivers by configuring them with the same communications settings.
For example, suppose you have a camera that runs under a particular PTZ driver, and suppose the camera has certain features that are not
supported by the PTZ driver. A tempting workaround might be to configure the camera under both the PTZ driver (so you can control the camera
using the advanced controls made available by the PTZ driver) and the Serial Output Driver (so you can take advantage of custom buttons to
access the additional features), but unfortunately, this will not work.
Only one device driver can have the communications port open. Whichever driver you launch first will open the port and be able to control the
camera.
