Cable connections Use an RS-232 cable to connect a controller to the projector's D-sub 9-pin connector. [. . . ] In this example, the picture mode is initially set to 0. Request: Notifications: *PMOD=1<CR> *PMOD=0<CR><LF> *PMOD=1<CR><LF> Example -- turning on the projector Request: Notification: Request: Notifications: *STAT=?<CR> *STAT=0<CR><LF> *W<CR> *W<CR><LF> *STAT=2<CR><LF> *STAT=1<CR><LF> (echoes request) (projector enters its warm-up state) (projector enters its on state) (current setting) (current setting) (new mode is active) RS-232 protocol reference 9 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. listing, each Except as noted in the keywordnot warm-up, keyword is valid only when the projector is in its on state, STAT=1 (and cool-down, or standby state). RS-232 keyword listing Keyword SRC Parameters ? Description Queries the current active input source: · 0 = no active source · 1 = VGA1 · 2 = VGA2 · 3 = composite video · 4 = S-video · 5 = component video YPbPr · 6 = RGBHV · 7 = M1 graphics Source functions RSRC 1 to 7, ? Attempts to use the specified source as the active input source, or queries the last source requested: · 1 = VGA1 · 2 = VGA2 · 3 = composite video · 4 = S-video · 5 = component video YPbPr · 6 = RGBHV · 7 = M1 graphics If the requested source is not available and AUTO is enabled, the projector scans for the next valid source; if AUTO is disabled, the projector returns the notification *SRC=0. Queries or sets input source auto-search: 0 = disabled, 1 = enabled 10 RS-232 protocol reference RS-232 keyword listing (continued) Keyword CSPC Parameters 0 to 2, ? Description 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. Video functions PMOD 0 to 2, ? Sets or queries the picture mode: · 0 = business graphics mode · 1 = theatre video mode · 2 = super-bright mode Note: The notification sent in response to a request using PMOD indicates the current picture mode, not the requested picture mode. It can take up to 15 seconds for the requested mode to take effect. Once it does, a second notification is sent indicating that the requested picture mode is active. WHIT BRT CON SAT TNT CTMP SHRP KEYV 0 to 10, +, ­, ?­50 to 50, +, ­, ? Sets or queries the white intensity. Sets or queries the color temperature: 0 = warm, 1 = neutral, 2 = cool Sets or queries the sharpness. Sets or queries the vertical keystone: · 0 = no keystone adjustment. · 1 to 50: shrinks the top of the display. · ­1 to ­50: shrinks the bottom of the display. RS-232 protocol reference 11 RS-232 keyword listing (continued) Keyword KEYH Parameters ­50 to 50, +, ­, ? Description 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 · 1 = Best Fit · 2 = Fill · 3 = 16:9 Note: All options may not be available for all input sources. Sets or queries the zoom level: · 0 = no zoom. · 1 to 9: progressively higher magnification. Sets or queries horizontal panning of zoomed images: · 0 (lower limit) = the left edge of the window aligns with the left edge of the screen. · 100 (upper limit) = the right edge of the window aligns with the right edge of the screen. Sets or queries vertical panning of zoomed images: · 0 (lower limit) = the top edge of the window aligns with the top edge of the screen. · 100 (upper limit) = the bottom edge of the window aligns with the bottom edge of the screen. SYNC None Automatically resynchronizes (auto-sync) the projector to the active input source. Note: The active input source must be VGA1, VGA2, analog M1, or analog RGBHV. [. . . ] Note: This keyword requires the projector to be in standby state (STAT=0). Note: Do not send any requests other than STAT in the time between the warm-up and on state notifications. Otherwise, unexpected results can occur. RS-232 protocol reference 15 RS-232 keyword listing (continued) Keyword STAT Parameters ? Description Queries the projector's current state: · 0 = standby state · 1 = on · 2 = warm-up state · 3 = cool-down state Note: STAT can be used anytime, regardless of the projector's state. ALERT Not a request -- see note Notifies when a system alert condition occurs: · 0 = lamp life warning · 1 = lamp life reached · 2 = lamp faulty · 3 = lamp problem · 4 = internal temperature too high · 5 = fan problem · 6 = ambient temperature too high Note: ALERT is sent only by the projector, and cannot be used in requests. Changing input sources When the input source is changed back to a source used previously, the video settings usually return to their previous values for that source. [. . . ]
