3 Quick Start Instruction
2) Connect the SX-Key/Blitz to a serial cable, and the serial cable to the serial (COM) port on the PC
3) Connect the SX-Key/Blitz to the 4-pin programming header with the VSS, VDD, OSC2 and OSC1
4) Insert one end of a 470 ohm resister into the RC7 socket (next to the upper left side of the
5) Insert the shorter leg of an LED into the breadboard hole that is closest (horizontally) to the resister
6) Plug the power supply into the SX Tech board and into an available wall outlet. (The power
7) If it is not still active, start the SX-Key Editor now.
8) In the SX-Key Editor window, pull down the File menu and select “Open” (or press Ctrl-O). In the
9) Pull down the Run menu and select Run (or press Ctrl-R). (The SX-Key software should assemble
Congratulations! You have just programmed the SX microcontroller with the SX-Key/Blitz
Development System. The program in the SX microcontroller should start running. The LED should
flash on and off (if wired correctly).
In case you get an error message after you have selected the “Run” option, make sure that you did not
modify the source code text in the editor window. If you did, simply re-load the original text by
opening it again, and then repeat the steps described above.
Should an error message like “SX-Key not found on COMx” appear, check that you have selected the
right serial port for communication with the SX-Key/Blitz, and that the serial cable is correctly
connected to the PC, and to the SX-Key/Blitz on the other end. Also make sure that the SX-Key/Blitz is
correctly placed on the 4-pin programming header, and that the SX Tech board is powered, i.e. the
power indicator LED is active.
