My monochrome module’s serial port has timed out, how do I troubleshoot?

Make sure the correct COM port is selected, and the FLASH Rate and uP Comm Rate is 115200 in the RS232 settings in the HTML Compiler.
To put the chip in program mode, pull DIP 1 down and restart the module. From here try to restore the Amulet OS (File --> Restore Amulet OS). Once this finishes you can try to reflash your project.
If you get the same timeout error you can then check to see if the chip is working correctly by doing the following steps:

• Start up Hyper Terminal (Accessories--> Communications--> Hyper Terminal) and connect using the COM port you are using. Select 115200 bits per second, 8 data bits, no parity, 1 stop bit, and no flow control.
• In program mode, the chip sends out a "C" character every second over the UART, which we can see in Hyper Terminal. Once the connection is set up and the module is plugged in and powered up in program mode you should be able to see "C" characters coming out. If you see them, the chip is functioning and the physical connection is set up properly.

You may want to review the physical connection if you aren't using our Program Interface Board. Usually it's just some flipped wires. If you are using our PIB and you cannot see C's then there is more to troubleshoot.
