CRM Chroma / luma Delay
Use Crm to set the time delay (20-50) between the chroma and luminance in decoded signals.
CsP Color space
CSP specifies which color space the input signal uses. 0=RGB, 1=YprPb, 2=YPbPr (HDTV).
DeF Factory Defaults
Use DeF to reset all parameters in the projector to factory defaults—all source setups are
deleted, all factory-defined color palettes are restored, and all user adjustments/preferences are
set to default values. DeF may also change your baud rate and projector number. nOTe: you
must include P1 = 111 in any DeF message. This requirement prevents accidental use of DeF.
Because the DeF message can take a fairly long time, it is a good idea to include the optional
acknowledge code ($) to determine when the defaults have been completed—i.e., ($def 111).
Dls Delete source
Use DLS to delete a specific locked or unlocked source setup (1-50), or to delete all unlocked
source setups (0). To delete all setups, even those that are locked, you must first unlock all
source setups using the memory lock command (mlK S0 0).
DlY Delay
Delay
Use Dly to delay a real-time event for a number of milliseconds (1-65535ms).
For example:
(rTe G 5 H "(Dly 100) (PWr 0)") = When pin 5 goes high, Delay 100ms, then power off.
DRK Dark Interval
Use DrK to control the time interval—in active output lines—between frames projected to the
screen, so that active 3D applications are well-synchronized with shutters in 3D glasses. range
depends on source frequency. For 3D models only.
DTa source Data
Use DTa to read from the projector (or load into the projector) all of the settings related to a
specific source setup (1-99), or pertaining to system parameters. This essentially creates a back-
up. If a source setup does not exist, use DTA to define all settings for it. This essentially creates
a back-up.
Keep in mind that a DTa request triggers reply messages for each setting in a source setup.
Because of the large number of replies, requesting an acknowledgement from the projector
($) is a good idea—receiving the ($) back confirms that the projector has returned all data and
completed the full DTa reply.

message
reply
the number of the source setup to read – must have leading 'S':
For example, ($DTa? S5)
If P1 = source#1-99, this identifies a specific source setup to read
P1 = the number of the source setup being read (1-99)
P2 = switcher number (0=projector)
P3 = slot number
P4 = the vertical frequency (cHz)
P5 = the horizontal frequency (10's of Hz)
