Numeric keypad- how to block signal? Answered
Here is the story. We needed a cell counter in out lab that counts 50 cells, most diff. counters do multiples of 100. I found a diff counter online, altered the java script so that it counts 50cells and bought a couple of numeric keypads to use with it since the computer keyboard isn't situated well for use while we are on the microscope. So the problem is that the two mics we used this with are set up in small room and the keypads are too close together so that if you are using one, both computers pick up the signal. So if two people are counting at the same time the counter picks up the typed input from both keypads.
So my question is, is there a way to block the signal from reaching the other computer?
They are both Targus Wireless Numeric Keypad. They are wireless and use radio frequency. I tried tinfoil that didn't work. The computers are spread out as far as they can. That is the only room we have for them since they are fluorescent microscopes and we need to work in the dark. I guess the obvious solution would be to just replace them with non-wireless but I was hoping that we could save money and try to get this to work. Wired ones may be awkward to use due to space constraints too.
