GoTo AdapterADAPTERGoTo Main

Short tutorial


First at each page there a short heading describing the adapter.

Pictures of the connectors

After that there is at each page there is one or more pictures of the connectors, usually there's two connectors. Sometimes there is some question marks only. This means that I don't know what kind of connector it is or how it looks.

UNKNOWN (To the computer)

There may be some pictures I haven't drawn yet. I illustrate this with the following advanced picture:

NOT DRAWN YET (To the computer)

Normally are one or more pictures. These are seen from the front, and NOT the soldside. Holes (female connectors usually) are darkened. Look at the example below. The first is a female connector and the send a male. The texts inside parentheses will tell you at which kind of the device it will look like that.

9 PIN D-SUB FEMALE (To the Computer).
25 PIN D-SUB MALE (To the Serialcable).

Texts describing the connectors

Below the pictures there is texts that describes the connectors. Including the name of the physical connector.

9 PIN D-SUB FEMALE to the Computer.
25 PIN D-SUB MALE to the Serialcable.

Pin table

The pin table is perhaps the information you are looking for. It should be quite simple to read. Contains mostly the following three columns; Name, Pin 1, Pin 2. Sometimes when not the same pin is connected to each side there is another column describing the name at connector 2.

Contributor & Source

All persons that helped me or sent me information about the connector will be listed here. The source of the information is perhaps a book or another site. I must admit that I am bad at writing the source, but I will try to fill in these in the future.
