Section 1
Installation
1-1. Installation Environment
Operating temperature : 5dC to 40dC
Storage temperature : _20dC to +60dC
Operating humidity : 20%to 90%(non-condensing)
Do not install the BDX-M1000 in the following locations:
.Areas where the unit will be exposed to direct sun light
or any other strong lights.
.Areas near heat sources.
.Dusty areas or areas where it is subject to vibration.
.Areas with strong electric or magnetic fields.
.Areas where is subjected to electricity noise.
.Areas where is subjected to static electricity noise.
To prevent the temperature rise inside the BDX-M1000,
pay careful attention to circulation of air in the place where
the BDX-M1000 is installed.
The rear side of the BDX-M1000 should be at least 20 cm
(8 inches) away from walls for ventilation and
maintenance.
c
Do not block the ventilation holes.
If the ventilation holes are blocked, overheating inside the
unit may cause fire.
1-2. Power Supply
1-2-1. Power Specifications
Power requirements : AC 100 to 240 V
50/60 Hz
Current consumption: maximum 2.0 A (at 100 V)
maximum 1.0 A (at 240 V)
A switching regulator is used for the power supply of the
BDX-M1000. The voltage within the range of 100 V to
240 V can be used without changing the supply voltage.
n
As the inrush current at turn-on is maximum 20 A (at
100 V)/maximum 40 A (at 240 V), the capacity of the AC
power must be adequate with the inrush current of maxi-
mum 20 A (at 100 V)/maximum 40 A (at 240 V).
If the capacity of the AC power is not the adequately large,
the breaker of the AC power at the supply side will operate
or the BDX-M1000 will abnormal operate.
1-2-2. Power Cord
w
To avoid a fire or an electric shock, be sure to use the
designated power cord. And do not damage to the power
cord.
n
For the customer outside of the area as shown above or in a
part of Europe, the above-mentioned power cords can not
be used.
Use the power cord that is applicable to the places in the
world.

1-4. Rack Mounting
The BDX-M1000 can be mounted in a 19-inch standard rack.
n
.When the BDX-M1000 or the peripheral equipment is mounted in a 19-inch standard rack, it is recom-
mended to install a ventilation fan to prevent a temperature rise in the rack.
Make sure that all the units in the rack should be operated within the temperature range of 5dC to 40dC .
.Connect the enough long cables on the rear panel, considering that the BDX-M1000 is pulled out.
.An installation manual is supplied with the RMM-30 rack mount rail. However follow the instructions
in this manual. Because the rack mounting procedures of the BDX-M1000 are different from the
procedures explained in RMM-30 installation manual.
.To prevent falling the rack, fix the rack on the horizontal firm floor with bolts.

Required parts
.Rack Mount Rail, RMM-30
Rail with bracket : 2 pcs.
Screw (B5x8) : 8 pcs.
.Screw for inner rail (B4x8) (*1) : 6 pcs.
.Screw for rack mounting (RK5x16) : 4 pcs.
(Sony part number: 7-682-378-04)
.Washer for rack mounting : 4 pcs.
(Sony part number: 2-297-913-01)
(*1) : The BDX-M1000 comes with the eight screws. The
two screws of them are spare.
n
Be sure to use the RMM-30 Rack Mount Rail.
If a rack mount rail other than the RMM-30 is used, the
BDX-M1000 may be dropped by insufficient strength of
the rack mount rail. This may cause a injury.
Procedures
1. Turn the power off.
2. Remove the four feet from the bottom of the BDX-
M1000.
3. While pressing the stopper of the rail, pull out the
inner rail.
4. Attach the inner rails to the BDX-M1000 using the six
screws (B4x8) supplied with the BDX-M1000.
5. Loosen the screws fastening the rear bracket to the
outer rail, and adjust the position of the rear bracket
with the rack depth.

6. Attach the front and rear brackets to the outside of the
rack temporarily using the eight screws (B5x8)
supplied with RMM-30.
7. While pressing the stoppers of the inner rails, slide the
inner rails fully into the outer rails.
c
.Be sure to mount the BDX-M1000 in the rack with two
or more persons.
Trying to handle this job by one-person could occur to
injury.
.Be careful not to get caught your hand and finger in the
rack mount rail when installing the unit in the rack.
8. After confirming that the BDX-M1000 can be moved
smoothly, tighten the screws (B5x8) secured
temporarily in the step 6.
n
When securing the front brackets to the rack by
screws, pull out the BDX-M1000 about 20 cm
(8 inches), and fasten the screws of the front brackets
to the rack.
9. After installing the BDX-M1000 in the rack, secure
the unit to the rack by the prepared four screws
(RK5x16) and four washers.

If the output data rate is set more than 90 Mbps, the clock
of DVB parallel output will be set at 27 MHz.
The setting data rate becomes default at turn-on.

2-2-1. IPM-81 Board
n
The addresses on the board are shown by ( ) marks.
D201 to D203 (A-4, 5) (green),
D204, D205 (A-5) (red) : Status indicator
Indicates the result of the self-diagnostics at just after the
power on.
.If an error is detected :
Both of D204 and D205 light up, and D201 to D203
indicate the description of error.
D201-1 : Lights up when DRAM error occurs.
D201-2 : Lights up when Dual-port RAM error occurs.
D201-3 : Unassigned
D201-CH1, D202, D203 :
Lights up when control error occurs at input
channel. (Refer to the figure for the correspon-
dance of the indicators and the channels.)
n
When any error is detected, the operation of CPU will
come to stop.
.If an error is not detected (CPU starts up
properly) :
