q SLOT 1–4 [LOCK] indicators
These indicate the word clock status of slots 1–4. The
indicator is lit green if operation is normal.
NOTE
• If the SLOT1–4 [LOCK] indicators and the SLOT1–4 [SRC]
indicators and all WORD CLOCK indicators simultaneously
flash red at startup, overcurrent has occurred in a Mini-
YGDAI card, or a malfunctioning Mini-YGDAI card is
installed. Turn off the power and remove the card that is
causing the problem.
• If the SLOT1–4 [LOCK] indicators and the SLOT1–4 [SRC]
indicators alternately flash red at startup, the hardware
settings of the RSio64-D need to be updated (page 20).
• If the SLOT1–4 [LOCK] indicators sequentially light green in
the order of 1–4 at startup, the clocks of the slots are
synchronizing. This may take several tens of seconds.
w SLOT 1–4 [SRC] indicators
These indicate the SRC (Sampling Rate Converter)
status of slots 1–4.
NOTE
The SRC clock sent to a Mini-YGDAI card installed in a slot
is selected by the SRC WCLK DIP switch (page 11).
e SLOT 1–4 [SRC] keys
For each slot, these turn SRC on/off for the slot’s input
as well as output.

Unlit
No card is installed in the slot, or an unsup-
ported card is installed.
Green (lit)
LOCK
This indicates that a clock synchronized with
the clock source selected by the WORD
CLOCK select key is being input from the card.
If an external device is connected to the corre-
sponding slot, input/output is occurring cor-
rectly between that device and the RSio64-D.
If the sampling frequency is close, this status
is shown in some cases even if not synchro-
nized.
Green

SYNC
ERROR
A valid clock is being input from the card, but is
not synchronized with the clock source
selected by the WORD CLOCK select key. If
an external device is connected to the corre-
sponding slot, input/output is not occurring
correctly between that device and the RSio64-
D. Input/output will occ
ur c
orrectly if SRC is
turned ON.
Red (lit)
UNLOCK
A valid clock is not being input from the card. If
an external device is connected to the corre-
sponding slot, input/output cannot occur cor-
rectly between that device and the RSio64-D.

WRONG
WORD
CLOCK
The frequency of the clock source selected by
the WORD CLOCK select key is outside the
range of operating frequencies of the card
installed in the slot. Either set the frequency of
the clock source to be within the operating
range of the card, or turn SRC on. In the case
of an analog card, turning SRC on makes the
card operate at the RSio64-D’s internal fre-
quency of 48 kHz.
Unlit SRC is off.
Green (lit)
SRC is on, and the clock selected by the SRC
WCLK DIP switch is being input correctly.
Red (lit)
SRC is on, but an appropriate clock is not
being input. It may be that the clock selected
by the SRC WCLK DIP switch is not being
input, or is outside the operating range. Either
turn SRC off, or change the setting of the DIP
switch.
