S9 serial cable pinout

[d11in]

Hi there

I need to know the pinout of a S9 serial cable (one DB-25 to four RJ45 connector). Does anyone know a good manual about this issue? Let me know it.


Thanks in advance...

Hello,

I found this documentation, What Is the Pin-out If I Want to Convert an RJ50 Serial Connector to DB9 or DB25?

I hope it would help you

Hi Koni,

The S9 cable is actually a DB-25 to a single modular connector.  You will need four of these cables to utilize all four ports on a 4 port serial board.  The S8 cable is similar, but provides a DB-9 connector in place of the DB-25.

The pinouts of these connectors can be found in our Serial Quick Reference Guide.

Let us know if you have any more questions!

Hi Jason


Many thanks for your help. First, I thought the S9 cable is an interface to four modular connectors. Now it's completely clear, how the signals are routed through this cable. Many thanks again.
