Description of

The STK500 includes two RS-232 ports. One RS-232 port is used for communicating

User RS-232

with AVR Studio. The other RS-232 can be used for communicating between the target

Interface

AVR microcontroller in the socket and a PC serial port connected to the RS-232. To use

the RS-232, the UART pins of the AVR need to be physically connected to the RS-232.

The 2-pin header marked “RS232 SPARE” can be used for connecting the RS-232 con-

verter to the UART pins on the target AVR microcontroller in the socket. Use the 2-wire

cable to connect the UART pins to the RS-232. The connection is shown in Figure 3-9.

The block schematic of the RS-232 connection is shown in Figure 3-10.
