Property reference
Label
This property is of type Line of text and can be referenced with the variable name label.
Label used to help identify the component on the panel.
Max Channels
This property is of type Signed integer and can be referenced with the variable name max_channels.
Max number of concurrent channels allowed
I2C Address
This property is of type Fixed list of ints and can be referenced with the variable name MAC_WR_ADDR.
I2C address of the module - bit 0
HTML Source
This property is of type Fixed list of ints and can be referenced with the variable name html_source.
Sets the method for streaming data, we can either host it loacally using a property or refer to external files.
Max Pages
This property is of type Signed integer and can be referenced with the variable name max_pages.
Maximum number of pages we can serve using the embedded page type webserver.
Name Page 1
This property is of type Line of text and can be referenced with the variable name name1.
Name of HTML page 1 - index.htm is the default page that will be presented.
HTML Page 1
This property is of type Multiple lines of text and can be referenced with the variable name html1.
Embedded HTML code used for page 1
Name Page 2
This property is of type Line of text and can be referenced with the variable name name2.
Name of HTML page 2
HTML Page 2
This property is of type Multiple lines of text and can be referenced with the variable name html2.
Embedded HTML code used for page 2
Name Page 3
This property is of type Line of text and can be referenced with the variable name name3.
Name of HTML page 3
HTML Page 3
This property is of type Multiple lines of text and can be referenced with the variable name html3.
Embedded HTML code used for page 3
Name Page 4
This property is of type Line of text and can be referenced with the variable name name4.
Name of HTML page 4
HTML Page 4
This property is of type Multiple lines of text and can be referenced with the variable name html4.

Channel
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c::CHANNEL.
Channel selection
Baud Select
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c::BAUD_LIST.
Baud rate option selector
Baud Rate
This property is of type Signed integer and can be referenced with the variable name cal_i2c::BAUD.
Baud rate to be used
Stop Delay
This property is of type True or false and can be referenced with the variable name cal_i2c::StopDel.
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not
a 10ms delay between an I2C stop event and the next I2C start event.
Most modern microcontrollers will not have a problem so this property can be disabled to speed up the
I2C communications.
