Once connected to the RS-232 (or RS-422, if supported by your external equipment) port of the projector, controllers can access projector controls and setups, issuing commands or queries and receiving replies. This bi-directional communication is useful for: downloading projector software upgrades through CoRE Librarian controlling multiple projectors obtaining a projector status report automating events on the projector (source switching, adjustments, etc.) monitoring sequences of events diagnosing certain performance problems

4 0HVVDJH)RUPDW All serial communication passes in and out of the projector in messages. For example, to set the Contrast level to a specific value the controller sends a set message to the projector. To read the current value of a parameter the controller sends a request message asking for the information the projector then returns the data in a reply message. Projector messages use simple ASCII characters normal letters, numbers and punctuation and consist of a three-letter command code and any accompanying data. Opening and closing round brackets (parentheses) indicate the beginning and the end of a message as shown below. FPG GDWD Three-letter commands sent to the projector can be uppercase, lowercase, or a mixture. For example, the contrast commands 'CON', 'con' and 'con' are all the same. Replies from the projector are always uppercase. This simple protocol can be used with a straightforward connection between a single projector and controller. It can also be used when several projectors are connected together in a network, however all projectors will respond to all messages. See Figure 1. for an explanation of how to send messages to specific projectors within a network. When required, the basic protocol can be expanded to include additional information, such as when there are multiple parameters involved, or it can

Commands can set a projector control or preference to a specific value or request the current setting from the projector. Set Contrast to a value of 75: &21 Request the current Contrast setting: &21" After a request message is sent to the projector (see above example) a reply comes back. The projector Replies with data: &21 Replies are always: in upper case. identified with an exclamation mark. padded with leading zeros before the value. Parameter values returned by the projector (such as contrast level) are always either 3 or 5 characters in length regardless of their actual value the value is padded with leading zeros as needed. The length of a specific parameter will always be the same (for example, contrast is always returned as 3 characters, projector number is always returned as 5 characters). In the three-digit Contrast reply shown above, 075 shows that the contrast level is set at 75. If desired, basic messages can be expanded in function with the insertion of one or two special characters. $FNQRZOHGJLQJ 0HVVDJHV If you want the projector to acknowledge that a message has been processed, request this acknowledgment by inserting a $ just after the start code (, as shown. &21 The projector will then return a $ when processing of the message is complete: Note that the $ character is not accompanied by start and end characters it is the complete acknowledgment (it can be part of a message such as dealer message command). If the request for an acknowledgment was sent to all projectors on a network (broadcast), each projector will return a $ reply. NOTE: Requesting an acknowledgment of a request is redundant, however the acknowledge character will still be returned after the usual reply.

6 Except when sending large data blocks such as source data, message acknowledgment can be used instead of Xon/Xoff for flow control. (Wait for the projector to acknowledge that the previously sent message has been processed before sending the next message this way, the projector will never have to store any messages in a buffer.) &KHFNVXPV If desired, you can add a checksum character & to an RS-232 message for increased message integrity. Insert this character just after the start code. 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 as shown: FRQ The checksum is the low byte of the sum of the ASCII values of all characters between the first character of the checksum, including the space after the last data parameter. Calculate the checksum for the above set contrast command as follows: 6DPSOH )RUPDWV DQG 0HVVDJHV &+(&.680 FRQ VSDFH hh )h ( h h h h )h )h ZKHQ RQO\WKH ORZ E\WH LV XVHG 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 acknowledge and checksum, either character can occur first. Figure 1. shows how to construct and interpret some specific sample messages (ASCII) commonly used for one or more projectors.

7 )ORZ &RQWURO )LJXUH )RUPDWV DQG 6DPSOH 0HVVDJHV Normally messages can be sent to the projector before processing of earlier messages is complete the projector will just store messages in a buffer until ready to process. However, if a series of messages is sent it is possible that the projector will not be able to process them as fast as they arrive and the buffer will become full. If this happens, the projector will immediately send the 13h (Xoff) code to instruct the controller (or any devices preparing to transmit) to cease transmission. The controller must stop sending ASAP and at maximum before it sends 10 characters (approximately baud). The projector is able to accommodate the receipt of up to 10 more bytes after it sends 13h (Xoff) additional bytes may be lost. When the buffer is once again available, the projector will send a 11h (Xon) command to resume transmission. NOTE: Xon and Xoff controls apply to both directions of communication. The projector will not send more than 3 characters after it has received a 13h (Xoff) code.

8 )ORZ &RQWURO ZLWK $FNQRZOHGJHµ If the projector has not received a Xon one-minute after receiving a Xoff code it will assume that the Xon was lost and will resume transmissions. If the controller has received a Xoff and no Xon after one minute, it can assume that the Xon was lost. If the controller waits for an acknowledgment before sending the next message and does not upload a complete source setup (the only message that is longer than 20 characters), the projector will never send a 13h (Xoff) code and the controller does not have to handle flow control codes. 0HVVDJHV The following Table of Messages ( lists RS-232 messages used for communicating with the projector. When referring to the table, keep in mind the following guidelines: Set and Reply messages usually have the same parameters in the same format Request messages are requests for information and usually have no data Request and Reply messages use the same code as Set messages except that bit#7 is set. Data is described using one or more parameters (P1, P2, etc.), each having a specific value representing the state of that parameter. Parameters can have spaces between them. For example, (5pwr1) is the same as ( 5 pwr 1 ) Out-of-range values sent to the projector will be converted to the maximum or minimum value, whichever is closest. This function can be used to determine the range of control. For simple commands, the min/max request can also be used. (con?m) =>(con!m ) For those controls in which the projector normally displays a percentage (such as contrast is set to 72%), the RS-232 value represents the setting, not the percentage. For example, an RS- 232 contrast setting of 127 = 50%. Messages involving multiple parameters or other details are further explained in Messages with Multiple Parameters subsection.

19 '7$ 6RXUFH 'DWD The DTA message is used to request the data for a source(s), or system preferences. It is also used to define a new source and its settings. When requesting data the DTA message causes the projector to generate reply messages for each setting. These messages can be sent back to the projector at any time without the need for the DTA message to be used. However, the DTA message must be sent to define a new source if that source does not exist. In general, when requesting settings acknowledge ($) protocol should be used to determine when the last parameter has been received, but this is not required. 7DEOH 6RXUFH 'DWD Reading Settings for a Specific Source Description Message P1 = the number of the source to read must have leading S Reply Setting 1 Setting 2 Setting 3 Setting n $ P1 = the number of the source being read P2 = switcher number (0=projector) P3 = slot number P4 = the vertical frequency (chz) P5 = the horizontal frequency (10 s of Hz) P6 = input polarity & routing Bits 2-0 // horizontal sync source 0 = no sync 1 = horizontal on vertical input 2 = horizontal on horizontal input 3 = horizontal on green input 4 = horizontal on red input 5 = horizontal from Vid1 input 6 = horizontal from Vid2 input Bit 3 // set if composite sync (H&V) on same wire Bit 4 // set if horizontal sync has negative polarity Bit 5 //set if vertical sync has negative polarity Reply message for first source setting Reply message for second source setting Reply message for third source setting Reply message for last source setting Acknowledge of DTA message (if requested) Examples: ($DTA? S5) (DTA! S ) (CON! S ) (BRT! S ) $ Reading Settings for All Sources To read the settings for all sources the format is the same as for a single source except that the source number to use is 0. The reply will be the same as for a single source except that it will be repeated for as many times as there are sources. Examples:

20 ($DTA? S0) (DTA! S ) (CON! S ) (BRT! S ) (DTA! S ) (CON! S ) (BRT! S ) $ Downloading Source Settings to a projector To download the source settings to a projector the DTA message is sent first, which defines a new source, or redefines an existing source with the specified parameters. The various settings are then sent. The parameter format for the DTA command is identical to the parameter for the DTA! reply to a request. Examples: (DTA S ) (CON S ) (BRT S ) (DTA S ) (CON S ) (BRT S ) Reading Preference Settings The projectors preferences are divided into 2 groups, transferable and projector specific. The transferable settings are those settings that are valid for any projector or the same type such as orientation. Projector specific settings are settings that are unique to each projector such as color temperature setup (exactly the same numeric values will produce different color temps on different projectors. To specify transferable settings the DTA parameter =T and to specify projector specific settings the parameter =P. Special care must be taken when using the BDR and ADR messages. These are returned like any other setting when the preferences are being read however if they are sent to a projector they may change the way the network operates (i.e. the BDR message should always be broadcast to all projectors or you will be unable to talk to some projectors). Examples: ($DTA T) (BDR! 09600) (LPI! 00345) $ ($DTA P) (CTM! )

21 (CTM! ) $ Downloading Preferences to a projector To download preference settings to a projector just send the various setting as separate commands. Take care before sending BDR (baud rate) and ADR (projector number) messages because they may affect network operation.

Adjustments and parameters found in the Image Settings, Size and Position and Channel Setup menus are those that can be sent as RS-232 messages containing specific source identification. When information about a specific source is requested, three parameters are returned by the projector: the source number, status (0=OK, 1=source doesn t exist), and the value of the parameter in question.
