#### Use IIOP Orbix Communications

Depending on the version of Orbix installed on the I-DEAS server computer, the network communication will use one of two different communication protocols.

- For Orbix 3.0 and above, the network communications use the CORBA Internet Inter-ORB Protocol (IIOP).

- For versions of Orbix older than 3.0, the network communications use the non-standard Orbix communications protocol.

By default, I-DEAS 8 is installed with Orbix version 3.0. So, when connecting to I-DEAS 8 or higher, you should use the IIOP protocol. However, if you know that the version of Orbix is older than version 3.0, you should not use the IIOP protocol.

Note: I-DEAS 8 on an SGI or IBM computer typically uses Orbix 2.2 for network communications. Therefore, if you are connecting to I-DEAS 8 on an SGI or IBM computer, you will need to deselect the Use IIOP Orbix Communications check box.
