Name HiViz product code Photo Quantity Function Polarity and Connections Large project box
6.0" long x 3.5" wide x 1.875"
PB-L 1 Labels no photo Stick-on labels are provided in strips to identify the components on the project box. Template for box lid 1 A paper template is provided in order to obtain the correct placement of holes for the components. 9-V battery holder 9BH 1 9-V battery clips in to this laydown container. The supplied hook and loop strips are used to stick the holder down to the inside of the project box. red wire is positive; black is negative Pushbutton, momentary, normally open PBO 1 Used a test button for the delay unit no polarity Panel jack for AC/DC adapter PJ 1 Receptacle for 9-V AC/DC adapter as an alternate power source When the AC/DC adapter is not plugged into the jack, terminals 1 and 2 are shorted internally. This connection opens when the adapter is plugged in. Because of this feature, terminals 2 and 3 are used to supply power from the adapter, while terminals 1 and 2 are used to supply power from the battery. Terminal 2 is shared by the two power sources and is connected to ground. 3.5mm mono panel jack 35MJ 2 One of these is used as a receptacle for the microphone cord; the other is used as an input jack for triggers other than the on-board sound and photogate triggers. Examples include a contact trigger and a light-activated trigger. When a plug is not inserted into the jack, terminals 2 and 3 are shorted internally. This connection opens when a plug is inserted. Terminals 2 and 3 are used to connect the sound trigger and photogate to the delay unit internally. Terminals 1 and 3 are used to connect an external trigger to the delay unit.
3.5mm stereo panel jack 35SJ 3 One of these is used as a receptacle for the photogate cord and the other two are used for the output jacks. Terminals 1-3 connect to the sleeve, ring, and tip respectively of the corresponding stereo plug. LED holder LED-M 3 Used to mount LEDs on the project box. 1" Standoffs 4
Used to hold the PCB away from the lid components 4-40 bolts, 1/4" long 8 Used to mount the PCB to the lid and the standoffs
