1)  Table  2.  Identifies  the  10-pin  female  plug’s  pin  names
for the corresponding download mode.
(3) Circuit Board Header Connection
- The ByteBlasterMV 10-pin female plug connects to a 10-
pin  male  header  on  the  circuit  board.  The  10-pin  male
header has two rows of five pins, which are connected to
the device’s programming or configuration pins.
- The ByteBlasterMV cable receives power and downloads
data via the male header. Fig.1 shows the dimensions of
a typical 10-pin male header.
1)  Table  3.  Through  5  summarize  the  absolute  maximum
ratings,  recommended  operating  conditions,  and  DC
operating conditions for the ByteBlasterMV cable.

(4) Real-Time ISP with the Quartus II Software.
1) The programming file formats generated by the Quartus
II  software  that  support  these  two  features  are  the
Programmer  Object  File(.pof)  that  is  used  with  the
Quartus II programmer, and the Jam File(.jam) and Jam
Byte-Code  File(.jbc)  that  are  used  with  either  the
Quartus II programmer or other programming tools.
2) Ensure that you enable this feature before programming
a  MAX  II  device  through  the  Quartus  II  programmer.
You  can  enable  the  real-time  ISP  feature  by  selecting
the  Enable  real-time  ISP  to  allow  background
programming(for  MAX  II  devices)  option  from  the
Quartus II programmer window. Refer Fig.2.
3)  You  can  also  enable  the  real-time  ISP  feature  in  the
Quartus II software through the following steps:
1. Choose Options(Tool menu).
2. Choose Programmer under the Category section.
(5) MAX II Device Handbook, Volume1.
-  To  configure  or  program  one  or  more  devices  with  the
ByteBlasterMV cable and the Quartus II programmer.
1) Compile a project. The Quartus II compiler generates a
.sof file to configure APEX II, APEX 20K, Mercury, and
Excalibur  devices.  To  program  an  EPC  configuration
device,  a  .pof or  JAM  STAPL  format  file  should  be
used.
2)  Attach  the  ByteBlasterMV  cable  to  a  parallel  port  on  a
PC and insert the 10-pin female plug into the prototype
system  containing  the  target  device.  The  board  must
supply power to the ByteBlasterMV cable.
-  For  the  Windows  Nt  operating  system,  a  driver  must
be  installed  before  using  the  ByteBlasterMV  cable,
go  to  the  “ByteBlasterMV  and  MasterBlaster
Installation” section in the Quartus II.
3)  Open  the  Quartus  II  programmer  by  selecting  Open
Programmer  from  the  (Processing  Menu).  Choose
Setup...  in  the  Programming  Hardware  section.  Specify
the ByteBlasterMV cable and the appropriate LPT port.
Please see “Changing Setup” under the ByteBlasterMV
cable  in  the  Quartus  II  software  Help  menu  for  more
information.
4) Select either passive serial or JTAG programming mode
and  then  add  the  files  and/or  devices  you  want  to
program  or  configure  using  the  add  file..  or  add
device... 
buttons to create a chain description file(.cdf).
-  The  programmer  has  two  programming  modes  “
passive  serial  and  JTAG,  In  passive  mode,  you
select which SOFs to include in the device chain. In
JTAG  mode,  you  add  specific  devices  and
configuration devices to the device chain, in addition
to  POFs  and  SOFs,  and  you  have  several
programming options for each configuration device in
the  chain.  In  JTAG  mode,  you  can  verify  an  EPC
configuration  device’s  contents  against  its
programming  file  data,  check  that  a  device  is  blank,
examine  a  programmed  device  and  save  its  data  to
file,  or  use  its  data  to  program  or  verify  another
configuration device.
5)  Choose  the  start  button  in  the  Quartus  II  software  to
program or configure the device(s). The ByteBlasterMV
cable  downloads  the  data  from  the  SOF  and/or  POF
file(s) into the device(s).

5. Auto Adjust Component 480i/1080p 
RGB 1080p
5-2. Summary
- Adjustment component 480i/1080i and RGB 1080p is Gain
and Black level setting at Analog to Digital converter, and
compensate the RGB deviation
5-3. Using in strument
- Adjustment remocon, 801GF(802B, 802F, 802R) or
MSPG925FA pattern generator.(It can output 480i/1080i
horizontal 100% color bar pattern signal, and its output level
must setting 0.7V±0.1V p-p correctly)
* You must make it sure its resolution and pattern cause every
instrument can have different setting.
5-4. Adjustment method 480i Comp1,
Adjust 1080p Comp1/RGB
(1) ADC 480i Component1 adjustment.
- Check connection of Component1
- MSPG-925FA -> Model : 209, Pattern : 65
1) Set Component 480i mode and 100% Horizontal Color
Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL” 
2) After get the signal, wait more a second and enter the
“Ez-Adjust” with press ADJ key of Service remocon.
After then select “3.ADC 480i Comp1” with navigator
button and press “Enter”. It is automatically adjustment.
3) You can see “ADC Component1 Success” message
after Adjustment success.
4) Error Messages: When its adjustment is not correct,
“ADC Component1 480i Fail” message displayed. If
component is not connection “Component1 Not
Connected”, its format is not 480i then “Not Valid
Format”, its signal don’t out then “Check Signal Status”
message displayed. These messages will be displayed
just a second.
(2) ADC 1080p Component1 / RGB adjustment
- Check connection both of Component1 and RGB
- MSPG-925FA -> Model: 225, Pattern:65
1) Set Component 1080p mode and 100% Horizontal Color
Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL” 
2) If adjustment is correctly finished, “ADC Component1
Success” message will be displayed. But adjustment is
not correctly finished, “ADC Component1 1080p Fail”
message will be displayed.
3) After adjustment Component1 mode, move to RGB-DTV
mode automatically and RGB adjustment start. After
RGB Adjustment successfully finished, “ADC RGB
1080P Success” message will be displayed.
4) If Adjustment doesn’t success, check conditions all of
the adjustment condition and adjustment again. See
“Error Messages” sentence.
5) After adjustment finished, press “ADJ” key and exit from
Adjustment mode.
