Is there a way to keep the Digital-to-Analog (D/A) output signal on the KUSB-3102, KUSB-3108, or KUSB-3116 from floating when the module has no power applied to it from the host system?

Answer:You will need to have a DPDT Relay AROMAT TF2-5V connected to an available USB port on the same system.Also, when the host system has no power, both switches (one for the channel 0 line and the other for the channel 0 return) will be pulled to ground.
