3.1.1 Control Operations
The state of an LED is ON when its corresponding TTL input receives a TTL “high” signal
and is OFF with a TTL “low”. This is the factory-default operation. The signaling can
reconfigured to be the opposite (ON with a TTL low, and OFF with a TTL high) via a switch
setting (see the Configuration section in Installation chapter).
3.1.1 Mode Exit
Pressing OFF returns to the TTL Mode prompt. Pressing NO while at the TTL Mode
prompt, results in displaying the Ring Buffer Mode prompt, described next.
3.2 Ring Buffer Mode
The Ring Buffer Mode is a mode in which the ON/OFF state of each of the seven LED
channels can be controlled by a series of programmable settings that are sequenced by TTL
signaling (strobing) to the RING BUFFER input on the rear panel when the Ring Buffer is
run.
Figure 3-11. Use Ring Buffer prompt.
Pressing YES places the Lambda 721 into Ring Buffer Mode, asking if the current Ring
Buffer should be run, as shown in the following figure. Pressing NO, causes the next mode
prompt (Setup Mode) to display, described next.
Figure 3-12. Run existing Ring Buffer prompt.
Pressing YES runs the existing Ring Buffer. Pressing NO, displays the edit Ring Buffer
prompt, described next.
