Character /

Numeric

Commands

Commands to the projector are two general types. Character commands and Numeric

commands. Character commands in fact consist of two types. Some of them put the

projector into a particular adjustment mode. For example, sending a letter B puts the

projector into brightness adjustment mode. O nce in that mode, adjustments may be done i t

two ways. The character + (plus) and – (minus) respectively increase and decrease the

parameter. Alternatively, a numeric value can be assigned for the parameter by following the

mode character with an integer value, followed by a repetition of the mode character. For

example, the command B75B would set the brightness to 75% of maximum.

Other commands carry out a single action such as selecting a channel, deleting a channel,

etc. Some of these commands use a prefixed integer parameter, while others use following

integer parameters and/or text strings for channel names. For example, the command 12!

Would select channel 12 and I12 13 NYSC would copy channel 12 to channel 13 and give

the name NTSC to channel 13.

All numeric parameters are integers. A decimal point is neither needed nor recognized.

Channel names must consist of upper and/or lower case letters, the digits 0 through 9, the

under bar character “_” and blanks. Numeric parameters are ranged checked. For those

commands that us a percentage value of 0 to 100, values outside those limits are accepted

and limited to the range of 0 to 100. For commands that use absolute value parameters such

as Phase, values outside the allowed range are simply rejected. The acceptable range of

each parameter is indicated in the Character Command Tables.

Any non-digit character such as carriage return, comma, blank, tab, etc., terminates a

channel name. For this reason the command K12 would delete channel 12 but K 12 would

be rejected since a blank (non-numeric character) following the letter K would terminate the

search for the channel name parameter.
