usb 232 board communication between two computers

Hello

Yes the USB232 board should be able to do this no problem. You will have to setup the two boards as follows.

Jumper positions D and 3 on both boards.

Then use single core wire to link the following connections between the boards.

rx - tx
tx - rx
rts - cts
cts - rts

And then you should be up and running.

Hello

If you look in your device manager (right click my computer -> properties -> Hardware Tab -> Device Manager) then under the Ports section you should have the USB232 board listed as a com device with a number eg COM2. If this is not the case then you will need to install the device drivers available from the E-Block datasheets page. If the port is appearing correctly then you should use this port in Hyperterminal when setting up the connection.

You will also need to ensure that the baud rates match on each device by setting it to 9600 or 19200. For testing purposes you can also set the flowcontrol to none. All other options should be left as default.

If you have a multimeter or scope then you should be able to see the tx pin toggling as you type on the keyboard in hyperterminal.

Let me know how you get on.
