D22 (Red color) (R5) : CH4
Blinks when receiving the control signal from the equipment which is connected to the REMOTE 2
connector on the connector panel.
D23 (Red color) (R5) : CH5
Blinks receiving the control signal from the equipment which is connected to the REMOTE 3 connector
on the connector panel.
D24 (Red color) (R5) : SIO2
This LED indicates the status of the CPU (IC3 on the IF-523 board) which controls the two ports of
REMOTE 2 and REMOTE 3 on the connector panel.
Lights off : The CPU is operating normally.
Lights :
The CPU is not started up correctly.
Blinks :
The dual port RAM, which is controlled by the CPU, is abnormal.
D25 (Red color) (R5) : CH6
Blinks when receiving the control signal from the equipment which is connected to the REMOTE 4
connector on the connector panel.
D26 (Red color) (R5) : CH7
Blinks when receiving the control signal from the equipment which is connected to the REMOTE 5
connector on the connector panel.
D27 (Red color) (R4) : SI03
This LED indicates the status of the CPU (IC7 on the IF-523 board) which controls the two ports of
REMOTE 4 and REMOTE 5 on the connector panel.
Lights off : The CPU is operating normally.
Lights :
The CPU is not started up correctly.
Blinks :
The dual port RAM, which is controlled by the CPU, is abnormal.
D101 and D111 (H1) : SUB
These LEDs are provided exclusively for maintenance service. They indicate the state of the sub CPU
(IC142/CPU-263 board) which controls the LED on/off.
Display Using Area Surrounding LED
The area surrounding the LED indicates the status of the reference signal supplied from the DVS-7000A
which is connected to the SWITCHER connector of the connector panel.
. The area flashes in the clockwise direction around the LED :
The reference signal is in the 525 scanning line mode.
. The area flashes in the counter-clockwise direction around the LED :
The reference signal is in the 625 scanning line mode.
. All indicators on the surrounding area are lit :
There is no reference signal. This might be because the DVS-7000A main power is not turned on, or
the reference signal is not connected correctly.
