RS232 Codes
RS232 control is not necessary for operation but is a convenient way to control displays from a
computer at a distance. Most things you can do with the remote, you can do with RS232 commands.
Plus, you can send inquiries to the displays and find out the current settings and values.

RS232 Command Format
Commands sent from the initiator to the follower must have the following format:
(www:xyz) [CR]
Where:
● '(' and ')' indicate the start and end of the command data. If these characters are present,
the command processor shall assume that "valid" command data is present in the command string.
If these characters are not present in the command, the command processor shall assume the
data is not valid command data and ignore it.
● "www" indicates the command code. This field is case insensitive (i.e. "PWR", "pwr" and
"PwR" should all be treated as "PWR").
● ":x" is the destination parameter. This is an optional parameter that indicates which memory
the command is referencing. This parameter is reserved and shall not be used at this time.
● "y" is the operand, which can have one of the following values:
o '?' = "Get" operand
o '=' = "Set" operand
o '+' = "Increment" operand
o '-' = "Decrement" operand
● "z" is the value to set for this parameter. It can have one of two formats:
o Integer value: Any positive or negative number (example: 100)
o String value: Any string surrounded by double quotes (example: "This is a string")
● "[CR]" is the ASCII carriage return key (0x0D).
