How to use 9pin to PS/2 adaptor?

[carvedeye]

HI i have a 9 pin to ps/2 adaptor for my amiga but when i hook it up i get no respnse but the mouse works fine on my pc am i doing something wrong?

Is it a simple "serial to PS/2" adapter or a "PS/2 to Amiga" adapter?  The former will never work, and if it's the latter, you might want to provide the model information.  I think older ones required drivers.

sorry its a ps/2 to serial and i have no idea of the model number all it has is an "N"  on it?

If it's a PS/2 to serial adapter, you'll want to stop plugging it into your Amiga before you break something, it won't work.  Those are PC only, and generally only work with specific mice.  You'll need a smarter device than that to work with your Amiga, something like a Cocolino or Micromys.

Please listen to tone007 - He has hit it square on the head. It could hurt your Amiga...

You can get 9-pin to PS/2 adapters for Amiga but they are expensive, €30.

Simple PS/2 to serial adapter can work - but since they're electrically/mechanically only they require a PS/2 mouse that's compatible with serial. Plugging a non-serial PS/2 mouse might break the mouse and/or your miggy's serial port.

In addition, you'll need a driver to make them work as a mouse. There is absolutely no way to make them work on the normal mouse port without an adapter like alexh pointed out.

You need something like this http://aminet.net/driver/input/SerialMouseD.lha

Not sure if it works with a ps/2 mouse with a serial adaptor though.
(And you will need a 9pin -> 25pin adaptor too to try it).

Just to clarify what is being said here....

As originally stated, the Amiga's 9-pin ports are NOT serial ports.  They are Amiga mouse/joystick ports.  Completely electronically different from a serial port.  Plugging a PS/2->Serial adaptor into one of these ports can be VERY harmful to the device or the Amiga, as the power is on a different pin.  (and even if you moved the power to the correct pin, the joystick port still has no way of reading serialized data - it's a totally different port.)  The only things you should ever plug into an Amiga mouse/joystick port are Amiga mice, Amiga-specific mouse adapters, or Commodore/Amiga/Atari joysticks.

Now, you CAN use an old serial mouse on an Amiga, but through the 25-pin serial port on the back of the machine.  You could use a 25pin serial -> 9pin serial adapter, then use the 9pin Serial -> ps2/serial adapter, and then plug in a dual-mode serial/ps2 switchable mouse.  You'll then need to load the custom serial-port mouse drivers for the Amiga, and the mouse will only work in workbench and workbench-friendly applications.  It is only an exercise of complete pedantics that this is mentioned, though.  While you CAN do this, I have no idea WHY you'd ever WANT to do this...  It is MUCH less hassle and MUCH MUCH more compatible to just get an Amiga mouse.

Yeah I agree, just ordered a new mouse and a lyra 2 keybaord adaptor (my PC KEY adaptor blow a couole of days ago) and a led adaptor so i can hook up my led's inside my tower. Now all i need is a mediator LT4 and my Towered miggy is complete.
