101 What is Actually Sent in a Message Although you will send and read messages as strings of ASCII characters, the actual message travels as a sequence of bytes. Each character in this sequence requires 1 byte. See example below, which illustrates a “lamp limit is 2000 hours” reply from the projector. Maximizing Message Integrity For additional reassurance and/or maximum message integrity, you can insert one or two special characters: ACKNOWLEDGMENTS: If you want assurance from the projector (or group of projectors) that a set message has been processed, request this simple acknowledgment by inserting a “$” just after the start code “(“. When the projector executes the required action (such as a source switch, for example), the projector will send a “$” (only) back. This is a quick way to confirm success with set messages, and is particularly useful with long‐distance communication links or where the projectors and/or images are not visible from the controller. Acknowledgements can also be a type of flow control. Note that requesting an acknowledgement serves no purpose when included in a request message, since the acknowledgement will be redundant to the actual reply from the projector. However, if requested, the “$” acknowledgement from the projector will follow the reply. CHECKSUMS: For maximum message integrity, add a checksum character “&” just after the “(“ as shown below. You must then also include the correct checksum total (0‐255) just before the “)” end code. Make sure to add a space before the calculated checksum to separate it from the last data parameter: (&con64 240) The checksum is the low byte of the sum of the ASCII values of all characters between the “(“ and the beginning of the checksum. Calculate the checksum for the above “set contrast to 64” command as follows: CHECKSUM EXAMPLE = & + c + o + n + 6 + 4 + ‘space’ = 26h+63h +6Fh +6Eh +36h +$34h +$20h = 01F0h = F0h when only the low byte is used = 240
102 The projector collects all of the message bytes as defined in the first byte of the message, then creates its own checksum value for comparison with the checksum included in the controller’s message. If the values match, the message is considered to have been correctly received— otherwise the message is discarded. NOTES: 1) ‘h’ indicates a hex number. 2) If a “request” message has a checksum so will the reply. 3) If using both “acknowledge” and “checksum”, either character can occur first. Accessing Specific Source Setups For ASCII messages described in this document, it is assumed you are adjusting the current source setup (channel) rather than a different specific one. However, for several commands (for example, ASR, Auto Source) you can direct the message to particular source setup. To do this, insert an “S” and a source# (such as “S5”) before the parameter value—the source setup number can be thought of as a “P0” parameter prior to the first parameter, and can be preceded with an optional space. For example: (ASR S25 1) = Turn Auto‐Source on for source setup #25 Use “S0” if your setting should be applied to all source setups (channels): (ASR S0 1) = Turn Auto‐Source on for all source setups The “S” source setup function cannot be used for parameters affecting the projector as a whole such as projector address. Other Examples: (ASR 1) = Turn ASR on for the current source setup (ASR? S5) = What is the ASR status for source setup #5? (ASR!S005 001) = ASR is on for source setup #5 (ASR? S7) = What is the ASR status for source setup #7? (ERR 006 "ASR: Source does not exist") = Source setup #7 does not exist (ASR?) = What is the ASR status for current source setup? (ASR!000) = ASR is off for current source setup Other Special Functions To add functionality to a message, include one or more of the following special characters directly after the start code “(“. If you add more than one, they can be in any order. PARAMETER LIMITS: For single‐parameter projector function codes, you can find out the current range of adjustment by adding the letter “M” to your request message. For example: (LPL?M) What is the minimum and maximum lamp limit? (LPL!M000 5000) Minimum lamp limit = 0, maximum lamp limit = 5000. Ranges cannot be determined in this manner if the function has multiple parameters. Note also that for text‐based parameters, the “M” values represent the shortest and longest text strings possible.
103 “AUTO” MODE: For certain projector functions, you can add the letter “A” to your set message if you want software to choose the appropriate setting. A reply with an “A” indicates that the choice was auto‐selected. For example: (STD A) Set the video standard to the most appropriate option. (STD?) What is the current video standard? (STD!A4) The video standard was automatically set to option 4 (such as PAL‐M). Note that in these projectors, auto mode is supported only for selecting a video standard. Although other functions (such as Motion Filter) may offer an “Auto” choice in its list of options, a reply message from the projector will not include “A” to indicate that “Auto” it is selected—auto is simply an option chosen like any other. ADJUSTING A PIP IMAGE: When there are two images on screen, all messages affect the primary image—that is, the larger “background” image. To direct a message to the PIP window instead, add the letter “P” to your set message. For example: (CON P47) In the PIP window, set contrast to 47. (STD? P) What is the current video standard used in the PIP window? HELP TEXT: To have the Help Text for a specific command returned as a reply from the projector, add the letter “H” to your request message. For example: (CON?H) What is the help text for the Contrast Control? (CON! “The Contrast is crushed”) Reply from the projector. GLOBAL INQUIRY: Add the letter “G” in your request message to find out if the control is global. A reply of “001” is returned if the control is global. For example: (BDR?G) Is BDR a global control? (BDR!001) BDR is a global control. INDEX VALUE: When a control uses indexes for multiple values, insert an “I” into your request message to find out the specific value of the index parameter. For example: (BRU? I22) What is the value for White Field Uniformity specified by index 22? (BRU! 123) The value is 123 for index 22. ACCESSING A LIST: For a control with a list of available options, add the letter “L” to your request message to get a reply of the available options in that list control in the order they appear in the menu. The reply message includes the following four parameters: P1=1, item selectable P2=1, item displayable P3=value of item P4=text for item
104 Examples: (STD?L) What are the list options for the STD list control? (STD!L001 001 00008 “Auto”) (STD!L001 001 00007 “NTSC”) (STD!L001 001 00003 “NTSC4.43”) (STD!L001 001 00000 “PAL”) (STD!L001 001 00004 “PAL‐M”) (STD!L001 001 00005 “PAL‐C”) (STD!L001 001 00006 “PAL‐60”) (STD!L001 001 00002 “SECAM”) (STD!L001 001 00009 “?”) (STD!L111 “—END—”) The end of the list is marked with P1=111. You can also access the text for a specific item in that list by adding the value of that item after the L. For example: (STD?L4) What is the text for item for in the Video Standard list? (STD!L001 001 00004 “PAL‐M”) CONTROL NAME: To find out the name of the control you are using, add the letter “N” to your request message. If the control uses indexes for multiple values, insert the index number after the “N” to read the name of the index. For example: (CON?N) What is the name of the CON control? (CON! “Contrast”) (BRU?N2) What is the name for index parameter 2 for BRU? (BRU! “Left Side, R”) (BRU?N6) What is the name for index parameter 6 for BRU? (BRU! “Top Left Corner, R”) CONTROL TYPE: To find out the type of control it is that you are using, add the letter “T” to your request message. If indexes are being used for control with multiple values, insert the index parameter after the “T” to find out the type of control that the index is. For some slide bar or number controls, an additional parameter may be returned to specify the number of decimal places the control uses and if the control is to be displayed as a percentage (0=min and 100=max). If the reply message does not contain the letter “T”, than this function is invalid for that control. Baud Rates The baud rate setting determines the speed of communication to and from the projector on the RS232 or RS422 links. The maximum rate for the RS232 is 115200; for RS422 it is 19200. Set the baud rate to match that of your controlling device, such as your PC. If you are unsure about what baud rate to choose, refer to the documentation for the controlling device. In an existing network of projectors, if you discover that a projector has a different baud rate, use the pull‐down list and select the correct baud rate using the ENTER key — do not just scroll this control with the ARROW keys. Serial communication is always eight data bits, no parity.
105 Projector Enter a three‐digit number (such as “001”) to assign or change a number to the projector currently in use. If the current projector already has a number assigned, that number will appear here (for example, “004” in the menu shown above). Numerical identity for projectors enables you to communicate with a single projector within a multiple‐projector application (see also Proj key in 3.2, Using the Keypads). If you make a mistake in assigning or changing the projector number, press Exit to cancel. NOTE: When multiple projectors are being used and you want to adjust the color and edge blending settings for individual projectors to create one seamless image, you must assign different numbers for each projector to allow switching back and forth between projectors while adjustments are being made. Network Routing NOTE: Not applicable for stand‐alone projectors or simple serial networks with only one type of controller and linking. SEPARATE: Select “Separate” (factory default) to keep RS232, RS422 and Ethernet messages on their respective paths instead of being broadcast to the other types of ports. RS232 AND RS422 JOINED: Messages originating from an RS232 or RS422 controller will be relayed to all RS232or RS422 ports. Any Ethernet communication, however, will not. RS232 AND ETHERNET JOINED: Messages to and from the RS232 ports will also be relayed to the Ethernet port, and vice versa. Any RS422 communications will be isolated. ALL JOINED: All messages reach all ports, regardless of type. Ethernet Settings NOTE: Recommended for network administrators only. DHCP: Enable this checkbox if you want a DHCP server to automatically change the projector’s default IP address (0.0.0.0) to one that is valid and unique for use on the current Ethernet network. On networks without a DHCP server, or to simply override the automatic DHCP server function, delete the checkmark and enter the new “IP Address” settings desired. Remember that only a 0.0.0.0 address will trigger the DHCP addressing service, and only when the DHCP checkbox is enabled. IP ADDRESS: Enter a valid and unique IP address for use on the network to which the projector is currently connected. This address will overwrite any previous IP address such as the projector’s factory‐defined default (0.0.0.0), or one that has been assigned by a DHCP server or other user. It takes approximately 10 seconds for the projector to respond at its new address.
106 PORT: On some Ethernet networks, firewall restrictions may require that the port number of the projector be changed from its default of 3002. If so, enter a new valid port number here. It is highly recommended not to use a port # below 1000, as these ports are typically reserved for and used by common IP applications. SUBNET MASK AND DEFA ULT GATEWAY: The Subnet Mask and Default Gateway are automatically assigned when DHCP is enabled. If a static IP is being used, the IP must be assigned first since the projector estimates the subnet mask after the IP is entered. The Default Gateway is an optional router device used to send and receive data outside the subnet. NETWORK NAME: Set the name for the projector, as it should appear on the local network. The control is most useful when DHCP is enabled, since the IP address may change from one session to another. Broadcast Key Enter a checkmark if you want keypad commands sent to one projector to be relayed to all projectors in a serial network. Note that the key will temporarily “override” the effect of a broadcast setting and allow you to control a specific projector when necessary. Disable the setting for all but one (any) projector in a network. Front IR, Back IR and Wired Keypad Enabled: Enable or disable access to the projector menus via the IR ports, as located on the front and back of the projector. Separately, the Wired Keypad can be enabled for remote access, as desire.

108 Appendix D: 3D Your Wolf Cinema REFERENCE Series projector, when configured and built‐to‐order at our Berkeley, CA facility, is capable of displaying stereoscopic [3D] video images. The projector relies on advanced internal 3D processing components plus additional external hardware – such as stereo emitters and glasses – that complete the 3D system. NOTE: The addition of advanced 3D viewing technology must be performed at time of the original projector’s construction, and cannot be added at a later date. Standard 2D REF projectors are not upgradable to 3D. Images generated from a stereo 3D‐video source consist of a series of images (frames) that alternate quickly between two slightly different viewpoints, corresponding to your left and right eye. When these frames are displayed fast enough and viewed with special stereo glasses synchronized to the left/right (L/R) changes, the resulting image appears with the same depth and perspective that is sensed in the real world. NOTE: The type of special glasses can be active stereo or passive stereo glasses depending on the type of stereo controllers and screen used. REQUIREMENTS Stereo 3D applications require a stereo 3D‐capable source, special hardware/software setups (described below), the 3D Settings menu option to control the projector processing, synchronizing and displaying of your stereoscopic 3D source material. Hardware: • 3D enabled version of Wolf Cinema’s REF Series projector [REF‐700‐3D or REF‐1000‐3D]. • 3D Stereo Sync Cable (required for 3D REF Series models; insures minimum frame delay). This General Purpose Input Output (GPIO) cable is standard with all Wolf Cinema REF Series projectors. NOTE: See Appendix B: GPIO. • A source, typically a Blu‐ray player, or computer with a stereo 3D graphics card capable of displaying progressive scan (alternating frames) of OpenGL quad buffered stereo 3D applications (suggested cards include ATI or NVIDIA), and running under Windows, Linux, IRIX, HPUX, OSX or Solaris operating systems. • 3D Emitter for controlling active shutter glasses. • As an option, any qualified device that mounts in front of the lens of the projector that will process the light from the lens into a passive polarized light. Contact your Wolf Cinema dealer for more information. Software or content: • Any 3D software that supports active or sequential 3D stereo on a supported computer/graphic card. • A 3D video stream from video source that has been prepared to be sequential content. Supports stereo signals prepared on either a compatible Dual and Single link HD‐SDI format.
109 • Compatible passive dual channel sources, providing each signal type is frame locked and the input connections are identical. CONNECTING THE 3D STEREO SYNC CABLE This GPIO cable provides the means for synchronizing the various components in your 3D system. Your source, projector display output, and emitters or 3D passive filter system can then operate together with precision to minimize cross‐talk and color artifacts. Connect as shown below. Connecting One Stereo 3D Sync Output Connect the 3D Stereo Sync Cable output to your stereo 3D sync emitter or 3D passive filter system, PZE device. The L/R switching of the device can then be synchronized according to the controlling signal of choice—either the source input signal or the internally generated signal—as set in the 3D Settings menu. Connecting Two Stereo 3D Sync Inputs (Recommended for multiple sources). Connect your video card’s stereo 3D sync cable to either Input A or either Input B on the 3D Stereo Sync Cable. These inputs are provided to allow you to connect two different Stereo 3D sources and conveniently switch the display back‐and‐forth between them. Active and Passive Stereo 3D Configurations Typical hardware configurations for active and passive Stereo 3D systems are shown in Figure 1.
