Hi,
For remote testing purposes I've connected a USB modem to a 6V battery with a Rectifier Diode to drop the voltage to USB spec.
I want to test for a DSL connection on circuits without the link to a PC.
But when connected to the battery the modem does not initiate the DSL handshake sequence, so my question is:
Does the modem need a signal from the PC via the D +/- to start the DSL sequence. Would connecting the D +/- to the 5V or Earth provide the missing link?
Any Ideas?
Thanks!
