It's got problems:
GND isn't connected to the DB9.
D1 has it's terminals shorted.
Traces zig-zag all over the board when there are obvious shorter paths.
R5 right pin is too close to the output pad.
Resistors are too tiny (maybe), diodes are too big (looks like power rectifier package! (Is!))
Hmm.
The board and schematic are "inconsistent"; you need to fix that first. make sure that the "class" contents are the same, and make sure that the serial connector has the same value in both schematic and board. At that point, run the ERC and make sure it says that they are consistent, so that edits in the schematic will show up in the board as well (and vis versa, for certain types of changes in the board.) (always edit with both board and sch open. It's much easier to avoid the dreaded inconsistency than to fix it.)
You connected GND to pin 5 of the DB9 more securely on the .BRD, but it isn't connected in the schematic.
Use a pin-header from the "pinhead" library for your off-board connections. For this board, you should probably use 5 one-pin pinheaders that can be moved independently, rather than one 5-pin connector.
D1 still has a wire/signal between its pins...
It still has zig-zagged connections. Do you understand that every point on a copper trace is electrically identical (for practical purposes, anyway.) You do not have to connect the pins in the same order they are connected on the schematic, as long as all the pins connected are on the same trace somewhere. For example, here is what I did to GND:
There is a similar problem for the signal on pin 3 of the DB9.
Awesome....thanks !!!
I'm just beginning my way in the eagle stuff and Iit looks like I have a lot to learn....
UPDATE: I've fixed it and get to move the components closer. I've check the board and the schematic side by side and now I've got everything connected.
