The X5 connector is ESD sensitive!
Electrical stress may cause irreversible
damage of the Mini-PLC!
Please use the BARTH
®
VK-6 connection cable (Art. No.
0091-0006) to connect the Mini-PLC to the PICkit 3 pro-
grammer (Art. No. 0017-0045).
For PC connection the USB connection cable VK-16 (Art.
No. 0091-0016) and a PC with installed Windows
®
opera-
ting system are mandatory. Take care that the tappet of the
3-way VK-16 connector shows to right direction of the STG-
660 (black square).
Reversal connection only causes
malfunction and no damage of the
Mini-PLC.

Programming
To program the STG-660 please refer to the BARTH
®
pro-
gramming templates and the related datasheets.
Microchip
®
provides a large knowledge base for the PIC18
®
microcontroller series which is used in the STG-660. Seve-
ral templates and sample programs will help you to get in
touch with the native and hardware-oriented microcontrol-
ler programming using your favourite compiler tool.
BARTH
®
recommendes to integrate your compiler software
within the Microchip MPLABX
®
software which supports
both programming, simulating and debugging.
Get the latest MPLABX
®
software and several related soft-
ware tools for the STG-660 on:
