Programming cable

4 posts in this topic

Dear friends,
I need to build a programming cable for HMI micro panel type (MICRO INNOVATION AG) , the user guide for the panel is showing the programming port (RS232)from the panel side but does not shows the opposite side of the cable(PC side)!..
Please, can you deduce the both sides configuration from the attached image?..
Help me please...

Connect the pins above -- of your other device.
RxD -- TxD
TxD -- RxD
GND -- Signal Ground
DTR -- DSR
Ignore all others, in most cases.
Or optionally jumper DTR to DSR on each end.

If we knew exactly which port the other end was going to connect to someone may be more specific.

The PC end may need 7 and 8 linking (RTS/CTS in loopback) depending on the software being run.
