RS-232 Protocol Reference RS-232 connections This guide describes how to configure the projector for RS-232 communication with an external controller, and describes the RS-232 command keywords used to send requests to the projector. Cable connections Use an RS-232 cable to connect a controller to the projector’s D-sub 9-pin connector. The table below lists the connector’s pin outputs. ✎ When connecting a computer to the projector, use a null-modem cable.
RS-232 protocol syntax The following describes the general elements of RS-232 protocol syntax. For details about a specific keyword, refer to the “RS-232 keyword listing” on page 10. manual uses the symbols “” and “” to represent a carriage return and ✎ This line feed, respectively.
Notifications In general, every request sent to the projector generates one or more notification messages, which are sent to the controller. (The exception is unrecognized requests, which are ignored.) Actions initiated by the projector can also generate notifications. The projector is always in verbose mode, and sends notifications whenever a setting changes, whether as the result of a request from a controller, or as the result of an action such as a button press or menu change.
The following table illustrates the types of notifications that can result if a request uses incorrect syntax. This incorrect syntax...
Example — changing input source The following simplified example shows how the projector typically responds to a request to change the active input source. Note that the three latter notifications are delayed.
RS-232 keyword listing The following table shows the RS-232 keywords supported by the projector. If the parameter listing for a particular keyword is “None,” that keyword requires no parameter. as noted in the keyword listing, each keyword is valid only when the projector ✎ Except is in its on state, STAT=1 (and not warm-up, cool-down, or standby state).
RS-232 keyword listing (continued) Keyword Parameters Description Video functions CSPC 0 to 2, ? Sets or queries the active color space: 0 = RGB, 1 = YPbPr, 2 = YCbCr Note: The active input source must be analog RGBHV interlaced, analog RGBHV progressive, or component progressive.
RS-232 keyword listing (continued) Keyword Parameters Description KEYH –50 to 50, +, –, ? Sets or queries the horizontal keystone: • 0 = no keystone adjustment. • 1 to 50: shrinks the right side of the display. • –1 to –50: shrinks the left side of the display. ASPT 0 to 3, ? Sets or queries the aspect ratio: • 0 = 1-to-1 • 2 = Fill • 1 = Best Fit • 3 = 16:9 Note: All options may not be available for all input sources. ZOOM 0 to 9, +, –, ? Sets or queries the zoom level: • 0 = no zoom.
RS-232 keyword listing (continued) Keyword Parameters Description TRK value, +, –, ? Sets or queries the synchronization of the projector to the active input source. Note: The active input source must be VGA1, VGA2, analog M1, or analog RGBHV. VPOS value, +, –, ? Sets or queries the vertical positioning of the projected image: usable range is the maximum and minimum allowed by the active input source. Note: The active input source must be VGA1, VGA2, analog M1, or analog RGBHV.
RS-232 keyword listing (continued) Keyword Parameters Description Setup functions LANG 0 to 9, ? Sets or queries the language used by the projector: • 0 = English • 5 = Spanish • 1 = French • 6 = Traditional Chinese • 2 = Italian • 7 = Simplified Chinese • 3 = German • 8 = Korean • 4 = unavailable • 9 = Japanese Note: Some firmware versions may not support all languages. LSAV 0 to 1, ? Sets or queries the lamp saver status: 0 = disabled, 1 = enabled.
RS-232 keyword listing (continued) Keyword Parameters Description IPAD ? Queries the IP addresses associated with the connectivity module. The notification takes this form: *IPAD=IP_addr_1, IP_addr_2 where: • IP_addr_1 = the IP address of the module’s LAN connector. • IP_addr_2 (if present) = the IP address of a wireless network card connected to the connectivity module. For example: *IPAD=15.7.123.54, 15.7.123.55 SNUM ? Queries the projector’s serial number.
RS-232 keyword listing (continued) Keyword Parameters Description STAT ? Queries the projector’s current state: • 0 = standby state • 2 = warm-up state • 1 = on • 3 = cool-down state Note: STAT can be used anytime, regardless of the projector’s state.
