Connecting to the PC
Switch off PC and programmer. Insert the communication
cable included with your programmer package to a
free printer port on your PC. If your computer is equipped with
only one printer port, substitute the programmer cable for the
printer cable. Connect the opposite cable end to the
programmer. Screw on both connectors to counter-connectors.
This is very important. It may be uncomfortable to switch
between printer cable and programmer cable, though it is not
recommended to operate the programmer through a
mechanical printer switch. Use of an electronic printer switch is
impossible. But you can install a second multi-I/O in your
computer, thus obtaining a supplementary printer port, say
LPT2. So your printer may remain on LPT1 while the
programmer on LPT2.
Switch on the PC.
Connect the mains connector of the power supply (or the wall-
plug power supply itself) to a mains plug, then connect the
mini-DIN connector to the programmer's connector labeled
"12VAC". At this time all 'work result' LEDs (and 'POWER'
LED) light up successive and then switch off. Once the
POWER LED lights with low brightness then the
programmer is ready to run.
Next run the control program for .
Note: When the PC is switch off and you turn on programmer,
LED maybe not blinking, before programmer maybe
permanent on reset.
