OSDP Install Mode
When the selected reader expander has at least one Port 1/2 Network Type set to OSDP the OSDP Install Mode icon in the toolbar will be enabled. If the selected reader expander does not have any ports configured for OSDP the icon is disabled and cannot be selected.
Click the OSDP Install Mode icon to put the reader expander into OSDP installation mode, allowing it to pair with any connected OSDP card readers which are also in installation mode. The reader expander and card reader will establish a shared encryption key to enable secure channel communication.
For more information, see Application Note 254: Configuring OSDP Readers in Protege.
