15-pin to 9 pin cable -


#1

I have made by myself the cable to adapt the 15pin connector(FASTRACK) to 9pin connector(PC).

In some modems, the connection is working, in others it isn’t.

I have used RX, TX, RTS, CTS and GND pins.

Do you have any suggestions?
Is it possible to have the complete description how the cable should be done? (connections???)

Thanks a lot for your help.

Thank you SunilRao

your cable configuration is OK. It is working.

It is working on Fastrack M1306B and Supreme.

A question:

You say “…Flying wires SUB D 15CTS (Boot/Reset/GND)…”

Why GND??? I connected GND between the two connectors.

Again thanks a lot.

For IGNATIO72:
Your configuration seems not correct.

To assert Boot and Reset, you connect them to GND. 8)


#6

Note use of the ‘Code’ tags to preserve the layout…

The pinout of the 15-Way connector is defined by Wavecom;
The pinout of the 9-Way connector is a well-defined standard;

But I’m not sure that there is any established standard for the modular jack in this type of application :question:
