3. the green LED When the green LED is on instead of blinking it means that the junXion box is transmitting data continuesly This can happen when one or more analog input is floating This will not harm the device If you want to avoid this be sure that all analog inputs have a stable input You can do this by connecting the not used analog inputs to ground GND When you re using a noisy or sensitive sensor like an accelerometer it is unavoidable to have a continues dataflow Notes on the USB power LED When this USB powerLED is off while the USB is connected to the junxion box you should disconnect the junXionbox from the USB cable and search for a possible shortcircuit in your sensor wiring Notes on the External power LED When the External power LED is off while the external power is connected and turned on you should immediately disconnect the yunXion box from the external powersource The error will be found in wrong connections with the ultrasound 3 0 Using the junXion box Now that you know where to connect your switches sensors and ultrasound sensors it is time to hook up your sensors and switches connect it to the computer launch the junXion program Macintosh computers only and play 3 1 Example of connected switch SWITCH 1 3 2 Example of analog sensor connected A lot of sensors you can use are so called passive sensors This generally means they behave like variable resistors called
4. ER exceed the range 0 5 V When the junXion box runs on USB power the maximum amount of power available is 375mW This means that the 8 analog channels can deliver a total of 75mA to the sensors The result is that the average maximum current consumption per sensor is 9 3mA The powerline SV USB power should never be shorted to ground Don t solder on the board while it is connected to the USB When using an external power supply be sure to first connect the junXion box to the computer and then turn on connect the external power supply When powering off first disconnect the external power then disconnect from the computer The junXion box is HID compliant so you can connect it when your computer is already on 2 1 Switch Connections You can connect up to 16 switches to the junXion box The switch inputs are on the strips labelled CON6 CON7 en CON8 and are meant to switch to ground GND O junxXion a or sao Ly Oo Oa 66 pa fi O O oS p gt d gt R gogpooooooooopooonooo Y o og ave 3 o a5 ur pA pong ooog fo 4 2 nood b oo CONGO Inputs 1 4 CONS Inputs 5 12 CON7 Inputs 13 16 CON3 GROUND You should connect the switch as following switch switch input con6 con7 or cons GND con3 22 Analog Sensor Connections You can connect up to 8 analog sensors to the yunXion box The sensor inputs are on the strips labeled CON4 and CONS and have to be referenced to 5V
5. JUNXION BOX USER MANUAL Introduction The STEIM junXion box allows you to connect up to 8 analog sensors 16 switches and 2 channels of ultrasound to your computer via USB The jun Xion box is a bare printed circuitboard with all necessary electronics on it It s up to you to solder your sensors and switches on the board This means it is necessary to have some soldering experience as mistakes in soldering can cause the junXion box not to function correctly and might even break it beyond repair It is possible to use multiple junXion boxes at once with the junXion v2 software and a USB hub Aside from soldering experience it can be very helpful to have some electronics knowledge This manual provides the basic information you need to connect your sensors and switches to the junXion box For additional information on specific sensors or customized schematics for certain sensors STEIM refers to the internet Specifications The STEIM junXion box is a HumanInterfaceDevice HID compliant The STEIM junXion box is a lowspeed USB device USB1 1 1Mb s The junXion box connects to a host computer via a standard USB typeA typeB connector A D conversion amp bit Ultrasound distance measuring 12bit Contents 1 1 1 1 2 2 1 2 2 2 3 2 4 3 1 3 2 3 3 3 4 general information and warnings general safety warnings specific issues PCB connection layout switch connections analog sensors connections u
