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 than 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.

Using Custom Buttons

Figure 85. Device Control Dialog Box – Custom Buttons Tab
The Custom Buttons method of sending ASCII commands allows you to send commands that have been predefined by the system administrator.
Clicking a custom button sends the command associated with the button to the serial output device. Your system administrator should instruct you
in what each button does.
If the Custom Buttons tab is blank, the system administrator has not defined any custom buttons for that device.
To control a serial output device with a custom button, complete the following steps:
1. Open the Device Control dialog box for the serial output device you want to control.
2. Click the custom button for the command you want to send. The command is sent to the device.

Using a Script to Control a Serial Output Device

The system administrator can define scripts to send device-control commands to serial output devices. A script can be associated with a hotlink
or label that you click, or it can be a freestanding entity that you run from a menu. Your administrator should instruct you in what scripts are
available to you and what each script does.
To run a freestanding script, complete the following steps:
1. Open a script menu using one of the following methods:
•Click a custom window, and then press Alt-Space Bar.
•Right-click the device icon for a destination device.
•In the Device List, right-click the serial output device you want to control.
The device pop-up menu opens.
