What does DTE stand for? #9

Open mithro opened 10 years ago

Motherboard schematic says "The DTE is either Atlys VHDCI module or PIC18 USB modules." but DTE abbreviation isn't expanded anywhere and I have no idea what it means....

ayushsagar commented 10 years ago

DTE (Data terminal equipment) and DCE (Data communication equipment) is common serial terminolology. What we call a host in USB is a DTE in serial, and what we call the device in USB is called the DCE in serial. I'll expand the abbreviation.

Also, I'm not referring to the serial expansion module as DCE because the devices connected to the serial expansion board can also be a DTE. The serial expansion is just a passive module and DTE/DCE status doesn't apply. And btw, this terminology matters because DTE-to-DTE connections use RX,TX crossover cable.

This information should be included in the schematic or documentation somewhere (maybe the README?).

ayushsagar commented 10 years ago

I just used a standard term to refer to the PC side. DTE DCE concepts don't seem to have any relevance in the scope of the project. If a crossover cable connection is needed, it will be mentioned in the device's backpanel/documentation.

You should assume anyone viewing your repository has very little knowledge about serial or anything related.

Dumping the above comments into a README.md with a little be of reformatting/rewording would be fine.

Too much documentation is a better problem then not enough :P
