TVS100 Terminal Connection Trouble 1

[Nick8Noodles]

First off, I would like to thank everyone here for being so helpful; I've learned a lot from you all. Second, I'm new to this so please bear with me if I've made an error presenting the problem.

System Model Information
KSU - Panasonic TX-TD1232
VPS - Panasonic KX-TVS100

Problem Description
Unable to communicate/program the VPS though HyperTerminal via COM port.

Notes
- The communication medium being used is shielded RS-232C cable assembly (DB25 male to DB25 male) that is attached to a serial adapter(DB25 female to DB9 female) which is plugged into COM1(COM2 was also tested).
- HyperTerminal settings are as follows: 9600-8-none-1-none.
- Rotary switch has been turn to 5; and 1 has also been tested.
- Programming on the KSU and VPS have been reset to default.
- Four different computers with operating systems ranging from windows 95,98 to XP have been tried and failed.
- DPITS has been initialized and tested with the KX-T7235C manager phone by pressing intercom 165(VPS responds).

What’s' Supposed to Happen in my Head
From what I have sifted and read though on many pages and forms HyperTerminal must be configured and engaged while the VPS is off. The RS-232C cable with null modem adapter is connected to the PC and VPS. The rotary switch must be positioned at 5(or 1). When the VPS is turned on the little red-eyed Cyclops flashes and there is terminal output on screen indicating; etc. or something like that...

Feed Back Please
If you respond to this please be as detailed as possible, as I said at the begging I’m new to this, please help.

Pinout for DB25 female to DB9 female adapter
... I cant seem to find one?
are you suggesting I make my own cable?

you are missing a null modem adapter!!

 

[Nick8Noodles]

The gentlemen at the local radioshack assured me that the DB25-F-to-DB9-F 'adapter' was a null modem, curses!

I'm in the process of making my own cable, can anyone confirm that this is the right pinout?

25 pin connector 9 pin connector

pin 1 unused pin 1unused
pin 2 goes to pin 2
pin 3 goes to pin 3
pin 4 goes to pin 8
pin 5 goes to pin 7
pin 6 goes to pin 4
pin 7 goes to pin 5
pin 20 goes to pin 6

all you need to know for a homemade cable is in the book!!
but yor diagram looks good!! all you need from rat shack
is a null modem adapter and 25 to 9 cable with the proper genders!!

 

[Nick8Noodles]
