Channel Characteristics

Axcess Programming Language

Axcess first evaluates the Boolean expression. If the expression is evaluated as true, Axcess

replaces the expression with a 1; otherwise Axcess replaces it with a Ø. Only one of these will be

evaluated as true because a variable cannot have two different values at one time. Therefore, the

direct assignment will assign a 1 (On) to the Touch Panel button for which the expression is true,

and a Ø (Off) to those that are false. Assigning a 1 to a device-channel is the same as turning that

device-channel's output ON.

Sample Program

A complete example program using a subroutine is given below. Here are the basic requirements

for the program:

! The devices used are one infrared/serial card, three AXB-CAM boxes, and one AMX

Touch Panel. The device numbers are 6, 97, 98, 99, and 128, respectively. The IR/serial

cards will transmit infrared code to a video projector.

! The Touch Panel will have three buttons. Here are the functions to be associated with

each button:

! Button 57: Projector to input 5, recall Preset 1 on Camera 1.

! Button 58: Projector to input 6, recall Preset 1 on Camera 2.

! Button 59: Projector to input 7, recall Preset 1 on Camera 3.

Here is the actual program:

DEFINE_DEVICE

VPROJ = 6 (* AXC-IR/S: PROJECTOR *)

CAMERA_1 = 97 (* AXB-CAM: PAN/TILT *)

CAMERA_2 = 98 (* AXB-CAM: PAN/TILT *)

CAMERA_3 = 99 (* AXB-CAM: PAN/TILT *)

TP = 128 (* AXU-CVA: COLOR VIDEO PANEL *)

DEFINE_CALL 'CAMERA MACRO' (WHICH_CAM)

{

PULSE[VPROJ,WHICH_CAM-CAMERA_1+15] (* SELECT INPUT 5,6 OR 7 *)

PULSE[WHICH_CAM,1Ø1] (* RECALL PRESET 1 *)

}

DEFINE_PROGRAM

PUSH[TP,57] (* CAMERA 1 *)

{

CUR_CAMERA = CAMERA_1

CALL 'CAMERA MACRO' (CAMERA_1)

}

PUSH[TP,58] (* CAMERA 2 *)

{

CUR_CAMERA = CAMERA_2

CALL 'CAMERA MACRO' (CAMERA_2)

}

PUSH[TP,59] (* CAMERA 3 *)

{

CUR_CAMERA = CAMERA_3

CALL 'CAMERA MACRO' (CAMERA_3)

}
