| A control panel may optionally be used with PASS. The control panel may have a ESTOP switch (i.e. mushroom emergency stop switch), as well as a manual reset button, which may be embodied as a keyswitch or push button. When a control panel is used with PASS, a Manual Reset is required in order to activate PASS, and thus, start projector operation. In most cases, this is a simple keyswitch action but could also be a simple momentary push button. And when a Control Panel is used, PASS continually monitors the ESTOP button. If the ESTOP is pressed, PASS will immediately terminate all color and intensity signals, and forcibly close the shutter. PASS will also open the projector interlock signal path (ILDA pins 4 and 17). | A control panel may optionally be used with PASS.

| The Projector-Signal-Output connector on the PASS board should be parsed out into pairs of signals, and then directed to various components within the projector. The signals and recommended connections are discussed below. Note that since this is an IDC connector, the pin numbers do not correspond to the ILDA pin-out on a DB-25. HOWEVER, if you crimp a DB-25-connector onto the output ribbon cable, then the pins will correspond directly to the ILDA pin-out. This is because the pin designations of a DB-connector are “in-line” while the pin designations of an IDC connector are “even and odd”. | The Projector-Signal-Output connector on the PASS board should be parsed out into pairs of signals, and then directed to various components within the projector.

In most cases, laser projectors do not use these signals directly and in fact, when used with certain pieces of Pangolin software, these signals correspond to a Safety Coordinate System. It is recommended that these be left unconnected. | + | |
| - | * Pin 23 is connected to the ILDA input connector pin 12. This signal is reserved by ILDA for a light sensor output, but it is essentially unused by all manufacturers. It is recommended that this pin be left unconnected. | + | |

| - | * Pin 25 is the main Shutter output. Under normal circumstances the state of this signal will correspond directly to pin 13 on an ILDA input connector. However, in the event of a major fault, PASS will forcibly close the shutter using this signal. It is therefore MANDATORY that this be connected to a shutter driver. For maximum safety, the shutter should be a fast type of shutter, and one that also will fail-safe. This means that in the event of a mechanical or electrical failure of the shutter, it will remain closed due to the mechanical design of the shutter. Pangolin highly recommends shutters manufactured by the company called nm Laser Products (http:// | + | |

| - | * Pin 1 is the active input that corresponds to an external Emergency Stop (ESTOP) switch, such as a pushbutton or red “mushroom” type switch. When this pin is connected to Pin 2 (ground), ESTOP is activated. When Pin 1 is left floating, then ESTOP is inactive and the projector will be allowed to operate normally. | + | |
| - | * Pin 3 is the active input that corresponds to a Manual Reset. This may be connected to pin 4 (ground) through a momentary pushbutton switch or a key-switch. | + | |
| - | * Pin 5 is an active input that indicates that a control panel is being used. Pin 5 must be connected to Pin 6 when a control panel is used. If Pin 5 is not connected to Pin 6, then PASS will not wait for a manual reset when power is first applied. | + | |
| - | * Pins 7 and 8 provide +5V to the control panel. These may be used in conjunction with LEDs on the control panel. | + | |
| - | * Pins 9 and 10 correspond to Ground. These may also be used in conjunction with LEDs on the control panel. | + | |
| - | * Pin 11 is an output, which corresponds to the horizon detector within PASS. If this signal is LOW, it indicates that the Y position is below the horizon (within the audience area). If this signal is HIGH (approximately 4 volts), it indicates that the Y position is above the horizon. This signal may be routed through a resistor to an LED or pair of LEDs (bi-color pair) to give an indication on the control panel as to where the beam is within the Y space. | + | |
| - | * Pin 13 is an output, which corresponds to the velocity detector within PASS. If this signal is LOW, it indicates that the beam velocity is OK, and that PASS will not actively suppress laser output because of velocity (PASS may suppress laser output for other reasons however). If this signal is HIGH (approximately 4 volts), it indicates that the beam velocity is too slow, and that PASS will actively suppress laser output. This signal may be routed through a resistor to an LED or pair of LEDs (bi-color pair) to give an indication on the control panel as to the disposition of the velocity. | + | |
| - | * Pin 15 is an output, which corresponds to the light detector within PASS. If this signal is LOW, it indicates that the light that is detected by PASS is above the “Maximum Safe Laser Power” threshold setting. If this signal is HIGH (approximately 4 volts), it indicates that the light detected is below the “Maximum Safe Laser Power” threshold setting. Under ordinary circumstances, | + | |
| - | * Pin 17 is an output, which corresponds to whether or not PASS is “ready”. Once PASS has given a “armed” indication on Pin 19, and then once the “Manual Reset” is activated (by connecting Pin 3 to Pin 4), this signal will go HIGH, indicating that PASS will allow color signals to flow through the PASS board to the internal laser projector components. This signal will remain HIGH as long as there are no major faults detected, such as a Power Supply fault, Light Detector fault, other detectable major fault, or ESTOP being activated. This signal may be routed through a resistor to an LED or pair of LEDs (bi-color pair) to give an indication on the control panel as to whether or not PASS is active. | + | |
| - | * Pin 19 is an output, which corresponds to whether or not PASS is ready to be activated (“armed”). If this signal is HIGH, it indicates that the power supply is OK, ESTOP is not activated, and light is not detected and thus, PASS may be activated by performing a “Manual Reset”. This signal may be routed through a resistor to an LED or pair of LEDs (bi-color pair) to give an indication on the control panel as to whether or not a Manual Reset can be performed. If used, this LED should ideally be placed near the “Manual Reset” push button or keyswitch. | + | |
| - | * Pin 12 is an output, which corresponds to whether or not the computer feeding the ILDA input has commanded that light come out of the laser projector or not. If this signal is HIGH, it indicates that the light that PASS has detected that the computer has requested more than approximately 50% beam power from the computer. If this signal is LOW, it indicates that the computer is commanding 50% or less beam power from the computer. This signal may be routed through a resistor to an LED or pair of LEDs (bi-color pair) to give an indication on the control panel as to whether or not the computer has commanded light to come out of the projector. | + | |
| - | * Pin 14 is an output, which corresponds to the condition of the power supply, both within PASS and supplying the scanner amplifiers. If this signal is HIGH, it indicates that the power supply feeding the scanner amplifiers is 19 volts or higher. It also indicates that all of the power supplies within PASS itself are also within their acceptable ranges. If this signal is LOW, it indicates that there is a power supply problem of some kind. This signal may be routed through a resistor to an LED or pair of LEDs (bi- color pair) to give an indication of the state of the power supplies. | + | |
| ==== Status LED signals on the Control Panel connector ==== | ==== Status LED signals on the Control Panel connector ==== | ||
| - | * Pin 16 is a “Status LED number 1”. If this signal is LOW, it indicates that a power supply fault has been detected. | + | |
| - | * Pin 18 is a “Status LED number 2”. If this signal is LOW, it indicates that the PASS light sensor detected a light level that exceeded the “Maximum Safe Light Level” while the Y position was below the horizon. | + | |
| - | * Pin 20 is a “Status LED number 3”. If this signal is LOW, it indicates that PASS tried to extinguish light from coming out of the projector, but that the PASS light detector still detected light output. This would occur if a PCAOM or Laser Diode Driver continued to output light after being told not to. This would also occur if the “Minimum light level” adjustment of PASS is not set correctly. And finally, this might also occur if PASS did not detect light coming out of the computer even though the computer commanded light output. This would indicate either a laser failure or light detector failure. | + | |
| Note that unlike the other LED outputs on the control panel connector, the “Status LED” outputs will “latch” in the event that a fault is detected. They will remain in the latched state until a Manual Reset occurs. This allows you to determine the cause of any detected faults. | Note that unlike the other LED outputs on the control panel connector, the “Status LED” outputs will “latch” in the event that a fault is detected.
