Appendix: GRAFIK Eye Commands
NOTE: This entire appendix is a reprint of Lutron’s technical reference material.
Format for Commands
The RS-232 interface is commanded by ASCII strings in the following format.
Command
Parameters
: A 1 2 3 ... <CR>
Clea
r
Input
B
uffe
r
Command
Carriage
Return
Notice that capital letters must be used for commands and there are no spaces
between characters. To execute more than one command, enter a space instead of the
carriage return and enter the next command. Any number of commands can be
entered at one time, as long as the input buffer is less than or equal to 60 characters.
The commands are executed in the order they are entered. When commands have
been received by the RS-232 interface, the number of commands executed is
reported by the unit to the RS-232 link. The format for this is a statement in the
following form.
<CR><LF>~3 OK<CR><LF>
If unrecognizable data is received, an error statement in the following form is
reported.
<CR><LF>~ERROR # 6 0 OK<CR><LF>
The first number indicates the type of error and the second number indicates the
number of commands executed before the error. When referring to GRAFIK Eye
Main Units as command parameters, GRAFIK Eye 1 refers to the GRAFIK Eye
Main Unit addressed as A1; GRAFIK Eye 2 refers to the GRAFIK Eye Main Unit
addressed as A2, and so on. Up to eight GRAFIK Eye Main Units can be on the
MUX link.
GRX-AV-RS232 Command List
The following is a list of commands which can be used with both the GRX-AV-
RS232 and the GRX-AV-RS232/ATC Interface Controls.
(A) Select Scene
This command selects desired scenes on the specified GRAFIK Eye Main Unit(s).
The first parameter is the scene and the second is the GRAFIK Eye Main Unit(s)
which selects that scene. If an invalid GRAFIK Eye number is encountered, the
command only affects the GRAFIK Eye Main Units listed before the invalid entry.
For scene 10 enter an “A”; for scene 11, enter a “B”, and so on up to scene 16. Scene
numbers outside the range of 0-G return an error statement.
