Configuring Online Communication

Attach
The Attach function initiates communication between the HHT and a
processor. The Attach function allows you to:
• upload/download a program
• change processor operating modes
• clear the processor memory
• enter or remove a password/master password
• transfer memory between processor RAM and EEPROM
• monitor program execution
• monitor and change data file values
• force I/O
• search the user program for specific instructions and/or addresses
The function keys and menus vary depending on how the HHT and processor
programs relate. In this example, attach the HHT to node 4. Assume that the
HHT and processor programs are identical.
