Hello, I am wondering if you can provide me with the correct jumper configurations for my DRV2700EMV. It's function will be a Piezo driver only that will not be connected to the computer. It has an external power of 5.1 vdc on J2, and a 30khz/5.6vdc signal , from a NE 555 , on J5. I can't seem to generate any high voltage signal on the high voltage outputs nor see any signal at the out puts or test points. The 3 led' s on J7,8,and 9 are lit. Additionally, after about 30 seconds the dc voltage at the output connectors appear to be toggling high to low every 1/2 second.
