Computer Player Profile GPIO Table
Computer Player is very similar to Line type GPIO. The difference is that the GPO that would normally be used to indicate the channel ON status is changed to a Next pulse. The next pulse is sent each time the ON button is pressed while the channel is in the ON state.
- Channel is OFF and the ON button is pressed - Start Pulse (pin 4) fires. Next (pin 1) does not fire.
- Channel is ON and the ON button is pressed - Start pulse (pin 4) does NOT fire. Next pin (pin 1) DOES fire.
Inputs (GPI)
ID | Name | Pin | Notes |
GPI 1 | ON Command | Pin 11 | Momentary turns ON the console channel, triggers START pulse |
GPI 2 | OFF Command | Pin 12 | Momentary turns OFF the console channel, triggers STOP pulse |
GPI 3 | PREVIEW Command | Pin 13 | Active = PREVIEW ON Not Active = PREVIEW OFF |
GPI 4 | Not used | Pin 14 | |
GPI 5 | READY Command | Pin 15 | Latch to indicate READY (OFF button illuminated) for profiles defined with the READY enable |
Outputs (GPO)
ID | Name | Pin | Notes |
GPO 1 | NEXT pulse | Pin 1 | Momentary when ON button pressed and already in the ON state |
GPO 2 | OFF lamp | Pin 2 | Latching, during OFF state, and READY command if enabled |
GPO 3 | PREVIEW lamp | Pin 3 | Latching, during PREVIEW state |
GPO 4 | START pulse | Pin 4 | Momentary at transition to ON |
GPO 5 | STOP pulse | Pin 5 | Momentary at transition to OFF |
