Basic Configuration

5.4.3.Port Access

The Port Access parameter can be used to grant connection access to the MPC's DB-9 Console port, RJ-45 Remote port and RJ-45 AUX ports. Normally, the Console port

is used for connection to a local control device such as a laptop, the Remote port is used for connection to the optional MPC-DISPLAY unit, and the AUX ports are used for connection to additional remote MPC units. However, if your application requires communication with other devices in the equipment rack the Console port, Remote port and AUX ports can also be used for connection to these devices.

Administrator and SuperUser level accounts are always allowed access to the Console Port, and User level accounts can always be granted access to the Console port. Note however, that in order to allow an account to access the AUX ports and Remote port, these ports must first be reconfigured as serial ports as described in Section 5.8.2. When the AUX ports and Remote port are left in their default configuration, accounts will not be allowed to create connections to these ports.

In addition, the command access level will also determine which ports the account will be allowed to access, as summarized below:

•Administrator and SuperUser: Accounts with Administrator or SuperUser level command access are always allowed to connect to the Console Port. If the AUX and Remote ports are configured as serial ports, then Administrator and SuperUser level accounts will also be allowed to connect to these ports. Port access cannot be disabled for Administrator and SuperUser level accounts.

•User: User level accounts are only allowed to connect to the Console Port when port access has been specifically enabled for the account. If the AUX and Remote ports are configured as serial ports, then User level accounts can also be granted access to these ports.

•ViewOnly: Accounts with ViewOnly access are not allowed to create connections to the serial ports.
