installing Tamino and IIS on different machines

I want to have tamino on pc1 and IIS on PC2 .
What should I do exactly ?
(I read the docs but I did not get it.)
Can U tell me step by step what I should do ?
and what address should I use for accessing my DB? or

On the machine where you just have IIS you need install the X-Port component only. Start the setup.exe of Tamino, select custom installation, server components, X-Port component.

Once this is installed you need to modify the registry so the modiis.dll filter knows where to send the request to. This is documented within the documentation, see <tamino_version_dir>/HELP/INSTALL/IWCONFIG.HTM#msiis

I did all U said , I installed X-port on pc2 and I added these information to the registry of pc2 :

[HKEY_LOCAL_MACHINE\SOFTWARE\Software AG\Tamino\IIS Mapping\Prefix]
[HKEY_LOCAL_MACHINE\SOFTWARE\Software AG\Tamino\IIS Mapping\Prefix\tamino/mydb]

1- what value should I give to port ? xml port of mydb or xml/xts port ? or something else ?
2-I assign the xml port of mydb to port , and in X-plorer I give this address to connect to my database : and mydb
but I get a message that this is not a server !
what is the problem ?
