offsheet connector vs input , output , bidirectional port

[ashwinder s garcha]

can anyone please help me with attached pic
why we need offsheet connector
difference between input , bidirectional port . why cant we use input port instead bidirectional
can we use only net name to connect all line on all schematic pages

- I only use ports in Altium - you can automatically add the page number where signal continues. I think off-sheet connectors are used to keep compatibility with imports (e.g. import from Orcad would create offsheet connectors), I do not use offsheet connectors in Altium.
- port direction helps for easier schematic reading (you immediately see if the signal is input / output etc).
- port direction is also checked during ERC check, but I do not use this feature much as it is not perfect (e.g. Electrical Rules Check can show an error if you try to connect two output ports together)
- I think, there may be an option to make local page nets to become global and recognized in the whole schematic (multiple schematic pages), but it is not a good practice

So robert what u do if two ouputs connected together on different page

To the ports in Altium we can add page address, which show the other end of connection. Can we do the same with off-page connector?

- normally two outputs are not connected together. However, if I need to connect for example two open drain outputs, then I use port I/O Type Unspecified.

- I do not think so

or just set your porject ot have global nets (in the porject settings) and there should not be any issue but wyou wont have a hierarchical design anymore.. i always have global nets.. it saves a lot off hassle in my opnion.
