A
I/O UNIT ID indicator
This indicates the connector number (the number of
the connector used to control the DIO8) of the engine
DSP unit (DSP1D/DSP1D-EX) connected to the DIO8.
If more than one connector is connected, either A or B
will be automatically selected as the connector for
control, according to the connection status of the
INPUT and OUTPUT jacks.
If there is a problem such as an incorrectly connected
DSP unit or if the word clock is not locked, this will be
indicated by one of the following error displays.
Error displays
E1
:The OUTPUT connector of the DIO8 is connected
to the OUTPUT connector of the DSP unit. Please
connect it to the INPUT connector.
E2
:The INPUT connector of the DIO8 is connected to
the INPUT connector of the DSP unit. Please con-
nect it to the OUTPUT connector. (This will not be
displayed if the OUTPUT connector of the DIO8 is
connected.)
E3
: Either the cable connected to the INPUT or OUT-
PUT connector has become disconnected, or the
connection destination is incorrect. If the connec-
tion is correct, try replacing the cable. (This will be
displayed only if both INPUT and OUTPUT are
abnormal.)
UC
:Control signals are not being received correctly.
Make sure that the power of the DSP unit is on.
These error displays indicate an error for the INPUT/
OUTPUT A connectors if the PORT B SELECTOR
switch is set to 5-8, and indicate an error for the
INPUT/OUTPUT B connectors if the PORT B SELEC-
TOR switch is set to 1-4. Even if there is an incorrectly
connected connector, the error display will not appear
if there is another control connector that is usable.
UL
:The word clock is not locked. Make sure that the
word clock source is selected correctly, and that
the cable is connected correctly.
B
PORT B SELECTOR switch
Use this switch to select slots 1-4 or slots 5-8 to assign
the INPUT A/OUTPUT A connectors (referred to as
PORT A) and the INPUT B/OUTPUT B connectors
(referred to as PORT B).
If the PORT B SELECTOR is set to 5-8,
slots 1-4 are
assigned to PORT A and slots 5-8 are assigned to
PORT B for input and output signals.
If the PORT B SELECTOR is set to 1-4,
only PORT B
is available for input and output signals via slots 1-4.
In reality, slot 1-4 input signals are routed to OUT-
PUT A, and the INPUT B signal is output to slots 5-8.
If you wish to route slot 1-4 signals to both OUTPUT
A and B, use this setting.
To connect the DIO8 to the DSP1D/DSP1D-EX, make
one of the following settings, depending on your
application.
●
Using slots 1-8 of the DIO8 with a single
DSP1D/DSP1D-EX
1) Connect the INPUT A and B connectors of the DIO8 to
OUTPUT slot 1-6 of the DSP1D/DSP1D-EX.
2) Connect the OUTPUT A and B connectors of the DIO8
to INPUT slot 1-10 of the DSP1D/DSP1D-EX.
3) Set the PORT B SELECTOR to 5-8.
●
Using slots 1-4 of the DIO8 with two DSP1D/
DSP1D-EXs for Mirror mode operation
1) Connect the INPUT A connector of the DIO8 to the
OUTPUT slot 1-6 connector of the first DSP1D/
DSP1D-EX.
2) Connect the INPUT B connector of the DIO8 to the
second DSP1D/DSP1D-EX OUTPUT slot connector
with the same number as the first unit’s slot you con-
nected in Step 1).
3) Connect the OUTPUT A connector of the DIO8 to the
INPUT connector for INPUT slot 1-10 of the first
DSP1D/DSP1D-EX.
4) Connect the INPUT B connector to the second
DSP1D/DSP1D-EX OUTPUT slot connector with the
same number as the first unit’s slot you connected in
Step 3).
5) When you place the unit into Mirror mode from the
CS1D, the PORT B SELECTOR changes its setting,
depending on the operating status.
Note:
You can change the PORT B SELECTOR setting by
sending the control signal from the CS1D. At this
time, two dots (“. .”) light up besides the indicator
message described above.
If the PORT B SELECTOR switch setting on the
unit is different from the actual operation, one of
the following messages and the indicator message
described above will appear alternately.
•If the PORT B SELECTOR switches to slots 1-4:

•If the PORT B SELECTOR switches to slots 5-8:
