88Adder Port DirectAdder Port Direct is totally transparent communication system that allowssupporting devices to communicate with each other. Using the keyboardconnections that link each device, Adder Port Direct allows:• A controlling device to provide address details of the required port, the user’sname and access rights, mouse calibration and video mode information.• A controlled device to confirm the address and other details of the currentport.Such communication simplifies both the configuration and selection of systems,especially within a complex cascade structure. Adder Port Direct also allowsthe AdderView CATx Hosts option to directly control the connected switchingdevices (such as other AdderView CATx units in cascade) and then apply theappropriate video capture and mouse scaling settings. Adder Port Direct providesexcellent security control to prevent users from accessing systems for which theydo not access rights (‘sideways movement’) because each unit is fully informedof each user’s precise access rights.Port/host addressing using Adder Port DirectWhen adding new computers to the Hosts list, the option ‘Add entry forunrecognised host’ is provided to automatically add new entries if a port isvisited that does not already have a matching host entry. This is a useful optionfor simple configurations, but should be used with care when complex cascadesof units are being used as it may lead to more host entries being added than arestrictly necessary.Additionally, you can specify the port number of the required system using thesame format as if controlling the KVM switch directly. Port numbers MUST beentered within square brackets and can be specified to a maximum of fourcascaded levels.Examples[16] selects port 16 and is equivalent to the hotkey sequence +CTRL+ALT+–1+6[4105] selects port 5 on AdderView CATx unit that is cascaded through portgroup 41 (see cascade port numbering).
