All relays are supplied with a single NO contact. If a NC contact is required a link can be
changed on the back of the IO Board.

Relays are rated at 5A. They should only be used to switch low voltages (24V). To
switch higher voltages use intermediate relays.

All pulsed relays operate for 0.5 secs unless stated otherwise.

*Two additional pulsed relays have been provided to control the projector motor to make
it easier for manual buttons to be included. Projector off will have to be linked to have a
normally closed contact.

Notes on Inputs

Film Cue
This is fed into input 1. When the CA21 is running a session a film cue
causes the next step in the program to be executed.

Slide Cue
This cue normally comes from the carousel on the slide projector and
indicates the last slide is being shown. When a slide cue is received and the
slide projector is on, the cue behaves like a film cue and causes the next
step of the program to be executed. Otherwise the slide cue is ignored.

Fire
This input when activated executes the emergency sequence.

Film Break This input is activated to indicate the film has broken or ended.

Xenon Fail This input is activated when the xenon is off and deactivated to indicate the
xenon is on. It is commonly driven from a light dependent resistor.

Motor On
This input is fed from the motor relay coil (<24V). It provides feedback to
the CA21 so that motor control of interlocked projectors will work even if a
projector motor is operated from the projector consol (ie external to the
CA21). Leaving the input unconnected will ignore this feature. (If using
this input it should be on when the motor is on.)

Lense
The three inputs Lense Wide Screen, Lense Cinema Scope, Lense 1.66 are
connected to the micro switches on a Cinemeccanica projector. Together
they indicate the current position of the lense turret. They must be wired up
to the CA21 to generate the input levels detailed below.

The number of lenses is selected by setup option PJ.

With the three lense turret control, the appropriate turret relay is held closed until the three
inputs indicate the new position has been reached. The turret relay remains closed for a
further time equal to
tP=. The picture is turned on again after a delay of dd.

Setup Options
(PIN 3124)

CP
Clear all programs.

Ed
Edit disable - when set to 1 editing of programs will disabled.

Cn
Cinema number for use with status panels - the range is 0 to 40. With a value of 0
no status panel will be driven.

CA
Set this option to 1 to use the CA21 with CA-Link Central Control. Also set this
option to 1 to run CS30 Status Panels at 38.4k baud in conjunction with CA-Link.
Set this option to 0 to run with older CS30 Status Panels at 9600 baud. (CS30
Status Panels with software prior to version 2.50 can only run at 9600 baud.) Note
that when CA=1, and the CA21 is in idle mode, the F2 key is used to request the
next session from CA-link and the F3 key is use to enter a safe mode where
commands from CA-Link are ignored.

AG Auto Go - if this option is set to one, pressing GO, without first setting a starting
time on the clock, will start the session immediately. It is not necessary to press
GO then CUE. If the option is zero, pressing GO will enter run but will not start
the session until CUE is pressed. Auto Go also affects the operation of the Remote
Start and Remote Stop inputs. (See the next Section.) Note that when CA21s are
interlocked and
Auto Go is enabled (set to one), and GO is pressed, all other
CA21s in the interlock group will enter
go mode.

FS
Fader Slew Rate (0 to 4). 0 is the fastest rate, 4 is the slowest.

SL
This option defines the slide projector being used. 0 - operation with relays but
with no separate lamp control (Ektapro 3000), 1 - operation with relays but with
separate lamp control, 2 - Ektapro 5000 using a serial port, 3 - Simda using a serial
port. 4 - Hokushin controlled by relays,

Pt
The projection time of each timed slide. The range is 1 sec to 20 secs.

Sd
Slide lamp delay - the delay after the slide command is given until the slide lamp is
turned on. The delay is from 0 to 20 secs in 1 sec steps.

CC
Curtain Close Delay - the delay in Stop Slide from closing the curtains until the
slide lamp is turned off and the delay in Auto Stop from closing the curtains until
the stage lights are turned up. The delay is from 0 to 20 secs in 1 sec steps.

PJ
Type of movie projector. 0 is Christie, 1 is Cinemeccanica with a two lense turret,
2 is Cinemeccanica with a three lense turret.

Ld
Lens Delay - the delay from when the dowser is closed until the lens is changed.

tP
Turret Pulse Length - length of the turret relay pulse from 0.1 to 1.0 secs. With the
Cinemeccanica three lense turret, tP is the additional time the turret pulse remains
closed after the inputs indicate the correct turret position has been reached.

dd
Dowser Delay - the delay from the start of the relay pulse to rotate the turret until
the picture is turned on again. Except that with a Cinemeccanica three lense turret
dd is the time from when the turret pulse is removed until the picture is turned on
again.

SP
This option selects the type of sound processor interface to be used on the CA21. It
is set to a value between 0 and 5 inclusive.

If "SP" = 0 relays are driven to select the required sound format and the CA21
sound format status LEDs are driven by the format selected by the CA21. No
status information is used from the sound processor.

If "SP" = 1 relays are driven to select the required sound format and the CA21
sound format status LEDs are set based on lines connected to the CA21 processor
board from the sound processor. Status information from the sound processor is
used.

If "SP" = 2 relays are driven to select the sound format and the CA21 sound format
status LEDs are driven
