ROI-S05750 INITIAL LINE UP
3-30
Chart 3-9 DADE Adjustment
Step Procedure
Note: The DADE control applies in 1+1 configuration to adjust
delay time for RX hitless switching when the INTFC
status is indicated Outphase.
1 Connect the USB cable to the USB port of PC and the LCT port
of the IDU (see
Fig. 3-2),
2 Login to LCT using Internet Explorer,
3 Enter Login name “Admin”, enter Admin password and press
the “Login” button,
4 LCT Open window will be displayed, then

Note: The DADE adjustment is needed in initial lineup or when the IF CABLE is replaced. It
is not needed readjustment when the INTFC status is indicated In-phase. The setting
conditions are as follows:
DADE:Automatically adjust delay time based on either No.1 signal or No.2 signal
which it is selected by RX SW
under the Outphase condition of the INTFC
status
. The DADE control is processed assuring no interruption of traffic.
Offset DADE:Automatically adjust delay time based on either No.1 signal or No.2 signal
which it is selected by RX SW
under the Outphase condition of the INTFC
status.
Since the offset memory minimizes the latency delay, traffic
interruption occurs at that moment. This Offset DADE controls the delay
time difference to a minimum than DADE control.
DADE off: Set when DADE function is not used. For particularly, when low bit rate (10
to 20 MB) transmission is applied to the system, the DADE control is not
required.
