Yamaha O2R Owner's Manual page 299

The left side of the display is a list of the cards in the four option slots of the
02R. The indication varies depending on the type of optional card being
used:
• Cascade (CD8-CS)
• ADAT (CD8-AT)
• TDIF-1 (CD8-TDII)
• AES/EBU (CD8-AE/CD8-AE-S)
• YAMAHA (CD8-Y)
• Analog AD/DA (CD8-AD)
• Analog A/D (CD8-AD-S)
• No Connection
Beside each optional slot indicator is a row of four boxes defining the
connections to the card inserted in the corresponding slot.
Note: When a cascade card is inserted in any slot, the boxes defining the
connections are still displayed. However, you cannot select any of these items.
Across the bottom of the display are boxes for the external wordclock
(W.CLK IN), the digital inputs (2TR D1 and 2TR D2), and the internal
wordclock (INT 48k and INT 44.1k). To the left of the boxes are the
wordclock indicators.
There is also an indicator—inside the "Fs" box—that shows the current
wordclock frequency or status.
