92 Appendix A: GPIO This section explains how to use a GPIO link from the projector to external equipment, such as devices for 3D synchronizing. GPIO Port The GPIO connector located on the input panel provides a flexible method of interfacing a wide range of external I/O devices to the projector. There are 7 GPIO pins available on the 9pin D‐Sub GPIO connector, which are configurable via RS‐232 commands. The other two pins are reserved for ground and power ‐ see table below for pin identification. The serial cable required for connecting the external device to the projector GPIO connector, must be compatible with the external device. Configuring the GPIO The GPIO connector can be configured to automate any number of events using the serial command code GIO. Each Pin is defined as either an input or output depending on the desired outcome. Configure the pin as an input if you want the projector to respond to something the device does and as an output if you want the external device to respond to an action taken by the projector. For example, configure the pin as an output if you want the lighting in a room to automatically dim when the projector is turned on. By using the GIO command, you can also set the state of each output pin as high or low. By default, the state of each pin is high. The voltage applied to pins in the high state is +3.3V. A low state (or value of 0) will be read on an input pin if the circuit attached to the pin is open. A high state (or value of 1) will be read on an input pin if the circuit attached to the pin
93 is shorted to ground. This corresponds to a switch closing event. Example 1. Turn room lighting on when the projector is turned off. (Assumes a control/automation unit is configured to turn the lights on when pin 2 of its input goes high.) (GIO+CNFG “OOOIIII”) Set pin #2, 3 & 4 configuration to output and pin 6, 7, 8 & 9 to input (GIO+STAT “HLXXXXX”) Set pin #2 to high, pin 3 to low and the state of all other pins unchanged Query Command (GIO+STAT) Request the state of all pins (GIO+STAT “HLLHLLH”) Reply of pin states ‐ H means pin is high, L means pin is low (GIO+CNFG) Request the configuration of all pins (GIO+CNFG “IIIOOOO”) Reply of pin configurations ‐ pins 2, 3 & 4 are Inputs, pins 6, 7, 8 & 9 are Outputs NOTE: The strings in the commands refer to pins 2, 3, 4, 6, 7, 8, 9 in order from left to right.
97 Appendix C: Communications NOTE: Detailed RS‐232 Commands can be found in a separate Addendum entitled “Communications”. A serial link of RS232 or RS422 enables ASCII communication with the projector so that it can be controlled remotely from a PC or other controller. From a PC, connect a standard nine‐wire RS232 serial cable to the RS232 IN port. Or, for long‐distance (>100 ft.) links with an RS422‐ compatible PC or controller, connect RS422 cable to the RS422 port. To get started, first review the settings in the Communications submenu, which define and control how single [or even multiple projectors] are linked with each other and with an external automation platform.
98 Understanding Message Format All “remote control” information passes in and out of the projector as a simple text message consisting of a three letter command code and any related data. Opening and closing round brackets (parentheses) surround each message as shown below. Messages can be a command to set a projector parameter at a specific level, such as changing to a certain channel. Or the controller can request information, such as what channel is currently in use—the projector then returns the data in a reply message. Regardless of message type or origin, all messages use the same basic format and code as shown here. Where applicable, a message may expand to include additional parameters of related details. And, if desired, you can choose to include optional information such as acknowledgements, checksums, and network addressing. Basic Message Structure The following component fields comprise a standard ASCII message. Optional fields, such as extra characters for special modes, restrictions or added functionality, are shown in shaded areas. START AND END OF MESSAGE: Every message begins with the left “(“character and ends with the right “)“ character. Note that if the start character is received before an end character of the previous message, the partial (previous) message is discarded. PREFIX CHARACTERS (OPTIONAL): For acknowledgement that the projector has responded, and/or to maximize message integrity, insert one or two special characters before the 3‐character function code: $ Acknowledgment. See 2.4, Maximizing Message Integrity & Checksum. See 2.4, Maximizing Message Integrity FUNCTION CODE: The projector function you wish to work with, such as channel selection or gamma, is represented by a three‐character ASCII code (A‐Z, upper or lower case). This function code appears immediately after the leading “(“ that starts the message. In messages sent to the projector, a space between the function code and the first parameter (or special character) is optional. REQUEST/REPLY SYMBOLS: If the controller is requesting information from the projector, a “?” question mark appears directly after the function code. If the projector is replying, a “!” exclamation mark appears directly after the function code. For set messages to the projector, neither of these characters appear—the code is followed by the data itself (see next). OTHER SPECIAL FUNCTIONS (OPTIONAL): To add functionality to the current message, include one or more of the following special characters between the function code and first parameter. If more than one (M SP), add in any order.
99 A Auto Mode adjustment (rare—for video standard selection only). See 2.6, Other Special Functions E Enable Control Inquiry. See 2.6, Other Special Functions G Global Control Inquiry. See 2.6, Other Special Functions H Return the Help text for a control. See 2.6, Other Special Functions I Used as an index for controls containing many values. See 2.6, Other Special Functions K Keypad emulation. See 2.6, Other Special Functions L Return a list of options for ‘list’ controls. See2.6, Other Special Functions M Find min/max adjustments (i.e., range). See 2.6, Other Special Functions N Return the name of the control. See 2.6, Other Special Functions S Adjust a specific source setup only. See 2.6, Other Special Functions T Return the type of control (i.e. Slidebar etc.). See 2.6, Other Special Functions P Adjust image in PIP window. See 2.6, Other Special Functions DATA: The value for a given projector state, such as “on” or “off”, appears in ASCII‐decimal format directly after the request/reply symbol. You can add an optional space after the symbol— i.e., before the data—in a set message, but data in replies follow the “!” symbol without a space. Other details to remember about data: • All values returned by the projector (reply • messages) have a fixed length of either 3 or 5 characters regardless of the actual value—the value is padded with leading zeros as necessary. • Data in set messages to the projector does not require padding with zeros. • For any given parameter, data is always the same number of characters. E.g., the shutter value, which is either “on” (1) or “off” (0) is always 3‐digits: 001 or 000. • Within each message, multiple parameters of data must be separated by one “space” character. • Data pertaining to a source setup other than the current source setup is preceded by: the letter “S”, the source setup number (i.e., channel), and a space. This is similar to an “extra” parameter P0. • Text parameters such as channel names are enclosed in double quotes following the data, as in “Name”. TEXT PARAMETERS: Most data is simply a numerical value, however some messages also require text. For example, a channel naming message typically includes a text‐based name after the channel number—enclose this text in double quotation marks, as in “Tilt the Wagon”. Use all characters as desired except for the following special characters shown in the left column below—these require a 2‐character combination as shown:
