DATA: The value for a given projector parameter, such as ON or OFF, appears in ASCII-decimal format

directly after the request/reply symbol. Unless you add an optional space after the symbol (i.e., before the data)

in a set message, data immediately follows the request/reply symbol without a space. Other details about data:

• All values returned by the projector (

reply messages) have a fixed length of either 3 or 5 characters

regardless of the actual value-the value is padded with leading zeros as needed.

• Data in set messages does not require padding.

• For any given parameter, data length is always the same. E.g., the

picture mute value, which is either on

(

1) or off (0) is always 3-digits: 001 or 000.

• Within one message, multiple parameters of data must be separated by one

space character.

• Data pertaining to a specific source other than the current source is preceded by: the letter

S, the source

number (i.e., channel), and a space. This is similar to an extra parameter

P0.

• Text parameters such as channel names are enclosed in double quotes following the data, as in

Name.

TEXT PARAMETERS:

Most data is simply a numerical value, however some messages also require text.

For example, a

channel naming message typically includes a text-based name after the channel number-

enclose this text in double quotation marks, as in "

Tilt the Wagon". Use all characters as desired except

for the following special characters-these require a 2-character combination as shown in

Table 3.21:
