I/O Connections
FR1 and FR2 BNC Connector Assignments, R20AD Card Module
When the R20AD module is installed in an AJA FR1 or FR2 frame, a corresponding
group of 9 BNCs on the rear panel then provide I/O for the module. The
illustration above shows the connector assignments for both the FR1 and FR2
when used with the R20AD.
Note: See the topic “ External Reference Information ” later in this manual for
information on use of the Ref Loop BNCs versus the FR1/FR2 frame reference BNC
when connecting an external reference video signal.
