SERIAL NUM PROPERTY
Property ID: 1
Property Type: String
Length: 0 – 15 bytes
Get Property: Yes
Set Property: Yes
Default Value: The default value is no string with a length of zero.
Description: The value is an ASCII string that represents the device’s serial number.
This string can be 0 – 15 bytes long. This property is stored in non-
volatile EEPROM memory so it will not change when the unit is power
cycled. The value of this property, if any, will be sent to the host when the
host requests the USB string descriptor. When this property is changed,
the unit must be power cycled to have these changes take effect for the
USB descriptor. If a value other than the default value is desired, it can be
set by the factory upon request.
