B 1 RS 232 COMPUTER CONNECTION
The
SIMDA
protocol allows the control of all the projector functions through
serial link.
The programming of the software is made easy thanks to the powerful built-in
macro commands (random access, dissolve etc...).
The complete description of the protocol can be found in the manual “The
serial protocol of SIMDA projectors” which is available on request.
B1-1 SIMDA protocol (summary)
Mode : 9600 bauds, 8 bits, no parity, two stop bits, no handshake.
All commands are ASCII.
Generic specifications
“ / ” After reception of this sign the projector tests the serial line, clears
the reception buffer and echoes the “ / ”.
“ & ” End-of-command sign, may be indifferently “&” or “carriage return”
“ $ ” Acknowledgement of reception is returned by the projector at the end
of the execution for all UPPER CASE commands.
Example : C88& select the light at 88% before to resend “$”
j00& go to next slide (no acknowledge)
Order table (extract)
NB: Certain commands or certain modes are not available for alll the
projectors or on all the versions (see manual ).
“ xx ” parameter from 00 à 99 in “Decimal” mode (J20& order).
parameter from 00 à FF in “Hexadécimal” (J31& order).
ORDER DEFINITION Mark
Axx& switch lamp off, go to slide “xx”
●
Bxx& go to slide “xx” (Random access)
Cxx& set light to level “xx %” (0 to 100 or 0 to FF (mode depending)
●
Dxx& fade to “xx %” time specified by “Hxx& and Ixx&”
●
Exx& fade and step forward “100% to 0%” or “0% to 100%” time “xx”
●
Fxx& fade, no step
●
Hxx& set fading time up for “Dxx&”
●
Ixx& set fading time down for “Dxx&”
●
J00& step forward
J01& step reverse
J02& switch light off and step forward
●
J03& switch light off and step reverse
●
J05& open the shutter
J06& close the shutter
J07& step focus forward
J09& step focus reverse)
J11& projector reset

J13& get light level
●
J18& set time step to 1 sec (Hxx& and Ixx&)
●
J19& set time step to 0.1 sec (Hxx& and Ixx&)

J31& set hexadecimal mode (xx = 0 to FF)
J22& get projector model
J23& get software version number
J24& enable “AUTOSHOW” mode
J25& enable “TIMER” mode
J26& disable “TIMER / AUTOSHOW” mode
J27& enable “AUTOFOCUS” mode
J28& disable “AUTOFOCUS” mode

B1-2 Connection :
Use an appropriate cable for your computer environment with a 9 pin plug on
the projector side (If possible to be blocked by a screw) See the SUB D9
diagram.
Example : extension 9M/9F for a PC compatible (wire to wire).
Its is also possible to obtain the RS232 connection via the 6 pin DIN plug (PC
PROJ cable).
It is rigorously forbidden to use the two plugs simultaneously.
B2 - PROJECTION VIA SYNCHRONIZER OR
ACCESSORIES
B2-1 - “AUDIOVISUAL” plug (16) for synchronizer
Switch the I/O button (15) on “O” (Out) (external).
This plug allows the connection of the dissolve control.
Every function : Lamp control, step Forward/reverse, snap zero tray position,
power supply are available (see diagram DIN 12 / -1-).
Important: For projectors with a built-in triac (see TECHNICAL DATAS), the
dissolve unit triac controls the internal triac of the projector which controls the
lamp (see diagram DIN 12 / -2-).
B2-2 - 6 pin DIN plug (17) for accessories
Switch position (15) is set according to the device characteristics.
This plug allows a data line in standard RS 232. It allows also single remote
function as step forward, reverse and focus adjustment (see diagram DIN 6).
B3 - PROJECTOR MODES AND LED INFORMATION
PANEL (24)
All SIMDA projectors are fitted with a microprocessor. All internal functions of
the projector are independent and can be controlled externaly.
Internal electronics read external signals from its plugs and executes them.
The SIMDA 3262 and 3462 mode selector allows adaptation of different
external devices to get the best performance (fast slide change, direct random
access, RARO). This is useful with, for example, AVL, DATATON,
DATAVISION, ELECTROSONIC, SIMDA, STUMPFL and S’VISION devices.
S-DRA-U modes optimise the slide change to achieve the fastest change.
K mode allows adaptation of the projector as a single mechanism with a
slower slide change.
The built-in triac allows the lamp regulation and avoids electrical high power
connections.
B3-1 - DRA-K-S-U mode selecting
The table will help you to choose the right mode.
Projector is switched off.
Press simultaneously on both buttons 21/22 (Auto timer/Focus). Keep
pressing on these buttons and switch on the projector. When mode lights on
(30 to 34) release the two buttons. Only previous selecting mode is flashing.
Press on buttons 12 or 13 (forward/reverse) to change the mode selection.
When the right mode is reached, press on both buttons 21/22 to memorise
your selection and to validate the mode. Selected mode is light on.
