Hi

Currently trying shipplotter with my ICOM PCR1000 reciever.
Its works fine but cant get GPS USB support only GPS serial and my
Garmin 76c is usb connector into the laptop

Any ideas?


As an aside to Franky's question, I have a related question for the
technically adept here.

Is a serial to USB adapter a two way device?

In other words, if had a GPS with a USB connector, could you use a
serial to USB adapter to connect it to a COM port?

I've only used them to go from serial to USB and don't know if you can
go the other way with it.

Thanks,

Jack

USB is designed to be low cost to implement in a peripheral device, but
the tradeoff is it requires a lot of code and a fairly large amount of
CPU performance to implement for the host. A serial port just doesn't
support a high enough transfer rate to communicate with a USB device.
Therefore the PC *must* be on the USB side of the converter.
