Page 56: Saving And Restoring Configuration Files
4.2.2.2 Update System Software from USB Device If the AP20 is not connected to the Internet, you may update the software through a USB Flash drive. 1. First, obtain the software update file from the Datasat Digital Entertainment web page at http://www.datasatdigital.com.
Page 57 Save Master Config Save AP20 configuration to USB device as MASTER configuration, which may be loaded onto other AP20 units. This will erase from the USB device any existing MASTER configuration. Save Diagnostic Info Save AP20 Diagnostic information to the USB device to facilitate troubleshooting.

Page 120 S/PDIF2 (TosLink) S/PDIF3 (Coax) Operation The AP20 monitors the selected input signal from one of the S/PDIF or HDMI ports to determine the type ® of audio signal received. If a Dolby Digital stream is detected, the AP20 decodes the audio and places it on the first 8 channels (see Table 1).
Page 121 AP20 Installation and Operating Guide Version 1.2 HDMI Setup Options Additional Dolby ® Digital options are available to set the speaker configuration and phantom center option. These options are accessed through the menu path Formats → Format Options → HDMI Options.
Page 122 This card offers two inputs (Projector 1 & 2), see Figure 1 below. Both inputs have an LED to indicate which input is active. The automation in the AP20 must be programmed to switch the inputs at the proper time. In addition to these inputs, there are two Lt/Rt test points.
Page 123 Turn off the AP20’s rear panel power switch and unplug the power cord. • Remove one of the three cover plates from the AP20 option slots. All slots are identical. • Slide the H338 card into the card guides of the option slot and gently push the card into its mating connector.
Page 124 F3. AP20 Optical Format and Analog Input Setup Before the H338 card can be used, Optical formats must be created in the AP20 and the optical format must have the analog input source selected as Optical. The H338 card supports standard optical film soundtrack formats: Mono, A- type and SR-type.
Page 125 AP20 Installation and Operating Guide Version 1.2 To assign a format button, go to: Menu (System) → Formats → Assign Buttons Figure 5 – Format Button Assignment Select a Format to assign from the Assign drop down menu. Select a button to assign the format to from the drop down menu.
Page 126 Inputs from the film are on the left. The resulting channels are on the right side, and are internal to the AP20. Note that these are not necessarily the output channels as they and may be routed on the AP20 output (see Section 2.9.4 Assign Channels on AP20 in this manual).
Page 127 AP20 Installation and Operating Guide Version 1.2 Typical Setups for optical formats are shown below. While other combinations are possible they are not representative of what should be used with standard film formats. When Mono is selected: In this example, left total (LT) and right total (RT) are the inputs.
Page 128 AP20 Installation and Operating Guide Version 1.2 When SR is selected: In this example, left total (LT) and right total (RT) are the inputs. Outputs are: 1L = channel 1 is left, 2R = channel 2 is right, 3C = channel 3 is center, 5Ls = channel 5 is left surround, and 6Rs = channel 6 is right surround.
Page 129 F4.3. Wiring and Connections Projector 1 & 2 inputs on the AP20 are 9-pin female D-connectors. See Figure 8 below for pin assignments. Input from the solar cell is a 9-pin Male D-connector. PIN NO. DESCRIPTION...
Page 130 The right channel is nearest the edge of the film. To confirm proper wiring, while observing the projector output on a RTA or the AP20 setup screen, place a business card or similar object to block the side of the cell nearest the edge of the film.

Page 132 To manually adjust levels, select the button below the left input level bar and use the AP20 front panel adjustment knob to increase or decrease this level until it meets the reference line. Note: When using a laptop to VNC into the AP20, use the up and down arrows to mimic the action of the AP20 adjustment knob.
Page 133 Figure 14 – Crosstalk using Cat 97 test film Note: while running the CAT 97 test film you can also select Azimuth in the AP20’s optical set up screen. If alignment is correct you should be able to observe a cross on the screen as shown in Figure 15. The same applies to viewing on the oscilloscope in X/Y mode.
Page 134 Correct Figure 16 – Azimuth This can also be viewed on the AP20 screen by going to Menu (System) → Formats → Format Options → Film Options → Film Setup and Selecting Azimuth (see Figure 15). When Azimuth is selected, on the right a pictorial of the azimuth adjustment is shown.
Page 135 AP20 Installation and Operating Guide Version 1.2 Figure 17 – Focus After the flattest response is achieved by adjusting the projector optics, the final slit loss correction is made using the Parametric Filter Settings, see Figure 18. F4.4.5. Slit Loss EQ When Slit Loss EQ is selected a graph of the slit loss adjustment is shown on the right of the screen (see Figure 18 below).
Page 136 Next turn on the subwoofer channel, then select the Optical Bass Gain by pressing the <Gain> button. Use the AP20 fader knob, or up and down keys when using a laptop, to adjust the Optical Bass Gain to match the Center channel level previously noted on the RTA display. The Optical Bass Gain range is 0 to +10dBc.
Page 137 Digital Soundtrack Input is used to allow a smooth cross-fade from the optical playback to another analog or digital input source (that is connected to the AP20 rear panel). If digital soundtrack for film is not used then keep the selection at None (factory default).
Page 138 F4.4.8. Optical Surrounds Delay Settings To set surround delays, for the optical formats, a “Profile” must be created in the AP20 and assigned to the optical formats. Go to Menu (System) → Formats → Channel Profile → Edit Profiles Figure 22 – Audio Profile Edit Select Copy Profile and choose a profile to copy from the drop down menu (in Figure 22, “Profile 2”...

The AP20 mutes when switching from optical card to digital or analog input source This may occur if the digital soundtrack input is not set correctly. Go to the Film Card Setup screen and select Digital Soundtrack Input, in this menu choose the input source in use, analog or digital.
