• Generators with a DVI or HDMI output now support a "hot-plug formats" special mode, which configures the Format knob to list only formats reported by the EDID structure from the connected DVI or HDMI display. This format knob list is created automatically when a DVI or HDMI display is connected with the generator. To active this mode, hold down R and ASC while starting the generator, or use the SROP 16384 command. To switch between the EDID-based knob list and the standard knob list, hold down the R button while pressing and releasing the ACS button.

  When the generator is connected with a DDC-compliant analog display, holding down R while pressing and releasing the ACS button configures the knob list for the display.

• Added AFDtest image, which work in analog and digital modes. The AFDtest image demonstrates different aspect ratios and content maps. See the HDMI manual (update available soon) for more information.
• Added PixelRep image, which works with EIA/CEA-861B formats in both analog and digital modes. The PixelRep image can be used to apply pixel repetition after the format is loaded. Use the image to vary the number of pixels-per-pixel to render the image with repeated pixels for test purposes. For more information about pixel repetition, see the EIA/CEA-861B standard.
• The EdidData image now reads and parses the first timing extension block.
• Generator can load an 8-bit image (.bmp) directly from a PCMCIA card (instructions).

• Corrected short broad pulse delay for the 720p formats in analog mode.

• When using analog HDTV formats with tri-level sync type, the TSPG command and query can toggle between tri-level and bi-level syncs. The Bilevel, Trilevel Toggle key operation can also be used to toggle the tri-level and bi-level sync types (see the GenOps image for instructions).

• The generator now verifies PCMCIA SRAM cards after writing data. If the card is bad, Card is bad is displayed for 3 seconds.
• The EdidData image displays the hex sheet for the two blocks in case there is an extension block. Also, if the check sum value is bad, the EdidData image displays the check sum value that should be used.

• The "passed" message used with HDCP images now displays in the correct font.
• Corrected low DVI output voltage level with HDCP images on generators with a BroadCom transmitter.

• Added commands that read and write control signals for DVI transmitters.

  Quantum Data digital generators use either a BCM7500 (BroadCom) or a Sil 170B (pin compatible with Sil 168) DVI transmitter. Control signals for the BCM7500 and the Sil 170B transmitters are defined differently. To identify the transmitter in your generator, load the GenStats image. If DVI (SII) is displayed under Options, the generator has an Sil 170B transmitter. If DVI is displayed, the generator has a BCM7500 transmitter.

  The SCTL command sets the control signals of the DVI transmitter to HIGH. The RCTL command resets the control signals of the transmitter to LOW.

  The SCTL? and RCTL? queries read the status of the control signals from generators with an Sil 170B transmitter. You cannot read the status of the control signals from a BCM7500 transmitter.

  The BCM7500 has 8 dedicated pins for these control signals, 4 pins for each link. CTL00 (pin 96), CTL01 (pin 93), CTL02 (pin 92), and CTL03 (pin 91) are used for link zero. Also, CTL10 (pin 75), CTL11 (pin 74), CTL12 (pin 71) and CTL13 (pin 70) are used for link one.

  The SCTL and RCTL commands take one parameter, a single byte in hex. Each bit corresponds to a control pin, making the value a mask. The least significant bit is associated with CTL00, and the most significant bit with CTL13. The SCTL command sets the bit with value "1" to HIGH. The RCTL command sets the bit with value "1" to LOW.

  The mask is as follows:

  [CTL13 CTL12 CTL11 CTL10 CTL03 CTL02 CTL01 CTL00]

  Examples for BCM7500 transmitter:

  • Set only CTL01 and CTL11 pins to HIGH:

  R:\>SCTL 22

  • Set only CTL02 and CTL10 pins to HIGH:

  R:\>SCTL 14

  • Reset only CTL02 and CTL10 pins back to LOW:

  R:\>RCTL 14

  • Reset CTL00 and CTL12 pins back to LOW:

    R:\>RCTL 41

    Note that CTL03 and CTL13 are not affected by these commands since these two pins are used for HDCP control.

An Sil 170B transmitter has two control signals, CTL1 and CTL2, which are controlled through the I²C bus on the Sil 170B. The commands described above can also control these signals by using the least significant 2 bits in the byte, and ignoring the other bits.

Examples for Sil 170B transmitter:

• Set CTL1 to HIGH:

R:\>SCTL 01

• Set CTL2 to HIGH:

R:\>SCTL 02

• Set both CTL1 and CTL2 to HIGH:

R:\>SCTL 03

• Reset CTL2 to LOW:

R:\>RCTL 02

For the SiI 170B, use the RCTL? or SCTL? query to read the status of these two signals.

After running the commands above, the following query would return 01:

R:\>RCTL?

• Added support for reading the enhanced display data channel (DDC) using the I²C bus. All parameters are hex values.

  i2cr? e_ddc ddc_addr1 segment_num ddc_addr2 offset bytes

  This example returns the 128 bytes of Extended Display Identification Data (EDID) data from the monitor:

  i2cr? e_ddc 60 0 a0 0 80

• Added support for new Quantum Data video standards.
• For the DDC auto-configuration, the format created from the first detailed timing is now assigned the gamma, sync swing, and video swing values from the EDID data. Previously, it was set to no gamma, and the swings were 700mV and 300mV. The vertical total also has been corrected for interlace formats, since the EDID detailed timing returns the values for one field while the format requires the values for one frame (for example, two fields).
• Added standard colors gray -2% and gray -4%, which are blacker than black.
• The GraysAll image now displays the gray level.

• When using the HDCP tester mode with a sequence that contains an HDCP image (HdcpA1B1, HdcpA1B2, HdcpA2B1, HdcpA2B2, or HdcpProd), you no longer need to press the Step button to proceed with the HDCP testing.
• Corrected vertical pulse for progressive European separate sync formats. The vertical pulse was off by one half line and short by one line.

• Added the following commands to read and write the VESA DDC/CI (DDC2Bi) using the I²C bus. All parameters are hex values.

  i2cw ddcci dst_addr src_addr count [command+data+chk_sum]

  Use no spaces between the command, data, and chk_sum parameters.

  i2cr? ddcci dst_addr bytes

This example is from page 13 in the VESA DDC/CI specification:

i2cw ddcci 6E 51 81 B10F
i2cr? ddcci 6F 5

This example is from page 16 in the VESA DDC/CI specification:

i2cw ddcci 6E 51 85 C0XXXXXXXXCH
i2cr? ddcci 6F 7

• The AVSS (analog video signal swing) command now controls the video swing on the TV for generators with an ADV7194 chip. To identify the TV chip in your generator, load the GenStats image. If TV(AD) is displayed under Options, the generator has an AD7194 chip. If TV is displayed, you have the an HMP8154 chip, which cannot control the video swing.

• Added a parameter to the HVPD command and HVPD? query to write and read the pixel delay between the horizontal and vertical pulse. If no value is specified, the default value is 0.

• Creating custom fonts (maps) used with the FocusMxx images to generate a full screen of that font (special character, map) now works correctly. For more information, see knowledge base article 100149.
• Updated HDCP? query to test HDCP functionality with any static image. The query allows you to choose the key that is used (test or production) and the length of time that the HDCP test stays enabled. For more information, see knowledge base article 100145.
