CHAPTER 11:
THE CASTOR SLIDE PROJECTOR
INTERFACE
INTRODUCTION
The Castor Slide Projector Interface provides the necessary electronics to allow the Gemini General Purpose
Controller to control a standard slide projector such as the Kodak EktaGraphic Series. The Castor transforms the low
voltage control signals from the Gemini into the higher power signals needed to operate slide projectors. In addition,
the Castor senses several slide projector attributes, and transforms them into low voltage signals which are returned
to the Gemini for reporting to the Hercules Central Processor.
Each Castor is equipped with four channels to control slide projector power, lamp dimming, tray forward, and tray
reverse. When properly attached to the slide projector, the Castor can sense when the slide tray is in ‘HOME’ position
(slide position zero), when the projector is ready to advance or reverse the slide tray, and when the lamp has failed.

CASTOR SLIDE PROJECTOR INTERFACE
INSTALLATION
Each Castor Slide Projector Interface can control any standard slide projector that uses the seven pin Kodak
connector to access the lamp and tray functions. In addition, a round DIN plug is used to access the tray home sensor
on compatible projectors. Use the following procedure to connect the Castor to the slide projector and the Gemini
General Purpose Controller.
1.
Plug the slide projector power cord into the receptacle on the rear of the Castor.
2.
Plug the seven pin Kodak connector from the Castor into the appropriate receptacle on the
rear of the projector.
3.
Plug the round DIN plug from the Castor into the appropriate receptacle on the rear of the
projector.
Note: It is very easy to insert this plug incorrectly. Be careful to align the indention
in the round metal shroud of the plug with the key of the receptacle to insure correct
connection.
Note: If the projector does not have this connector, then this projector does not have
a tray home sense switch. Simply coil the cable and place it aside. Take special note
of programming precautions for projectors without home sense capabilities that will be
presented later in the manual.
4.
Plug the Castor power cord into a convenient receptacle.
Note: The Castor and the Gemini that control it must be on the same electrical power
phase to insure that lamp dimming will occur correctly. The easiest way to insure this is to
connect the Castor and the Gemini to the same power circuit.

5.
Connect the female end of the wedge shaped 9-pin (DB9) control cable to the male plug on
the rear of the Castor. The two screws can be tightened to insure that the cable will not be
accidentally pulled out of the Castor.
6.
Connect the male end of the wedge shaped 9-pin (DB9) control cable to one of the control
ports on the rear panel of a Gemini. The two screws can be tightened to insure that the
cable will not be accidentally pulled out of the Gemini.
7.
Use the front panel menu to select the ‘SP - CASTOR’ option for the control port to which the
Castor is connected.

CONFIGURATION FILE EXAMPLE
The example below uses from a default Configuration File which is distributed with new Hercules program disks.
Intelligent Controllers and their devices do not need to added to the Configuration File in any particular order, but the
default Configuration File should be used as a guide to help create some sort of consistency between installations.

EDIT DEVICE CODE - Enter (1-8) alphanumeric characters (spaces are illegal).
The first character must be alphabetic.
The example shows two different Gemini units. Unit 1 controls four slide projectors, so it has four Castors connected
to the control ports. Unit 2 controls two slide projectors, so it has two Castors connected to the control ports.
The Unit Number is user defined and can be any previously unassigned value from 1 to 64. Some Intelligent
Controllers, with internally set Unit Numbers, are limited to a range from 1 to 32.
The Device Code and Device Name are also user defined. The Device Code is limited to eight alphanumeric
characters, but spaces are not allowed. The Device Name can be up to eighteen alphanumeric characters, and spaces
are allowed. Both entries should be as descriptive as possible to make them easy to remember.
The Device Type will determine how the Hercules Central Processor to correctly display and update the device
status. The correct Device Type for a Castor controlled slide projector is ‘SP’.

SLIDE PROJECTOR COMMANDS (TYPE SP)
Remember that all commands must be issued from the Hercules and directed at a particular device. The following
table lists all the commands available to control a slide projector using a Castor Slide Projector Interface:
Hercules Command
Command Name
Command Description
#A
# Sec Alternate (0.1 ≤ # ≤ 999.9)
Changes state of lamp (on to off or off to on) in a ramp of # seconds
duration.
#D
# Sec Dissolve (0.1 ≤ # ≤ 999.9)
Changes state of lamp in ramp of # seconds duration.
advanced by one tray position at the end of the down ramp.
#N
# Sec Dissolve On (0.1 ≤ # ≤ 999.9)
Lamp dims up in a ramp of # seconds duration to a lamp level of %
(Limit). Can be used to ramp from one % (Limit) to new % (Limit).
#F
# Sec Dissolve Off (0.1 ≤ # ≤ 999.9)
Lamp dims down in ramp of # seconds duration. Slides are advanced by
one tray position at the end of the down ramp.
#FNF
# Sec Dissolve Off (No Forward)
(0.1 ≤ # ≤ 999.9)
Lamp dims down in ramp of # seconds duration. Slides are advanced by
one tray position at the end of the down ramp.
FA
Fast Alternate
Changes state of lamp (on to off or off to on) instantly. Slide trays are
not advance when lamp turns off.
HC
Hard Cut
Changes state of lamp (on to off or off to on) instantly. Slide trays are
not advance when lamp turns off.
LN
Lamp On
Turns lamp on to a level of % (Limit).
LF
Lamp Off
Turns lamp off. Slide trays do not advance.
FZ
Freeze
When issued during a lamp ramp, the ramp will freeze at that level.
When issued again, the lamp ramp will resume.
PLMP
Pulse Lamp
Triggers ½ second lamp pulse.
F#,#
Flash Lamp #1, #2 (0 ≤ # ≤ 99)
Flashes lamp at regular intervals. #1 represents ‘on’ time in system
heartbeats; #2 represents ‘off’ time in system heartbeats. F0,0 disables
flashing. This command is a layered command. The lamp must be
ramped on with another command to see the effect. After the lamp is
faded down, a F0,0 cue must be entered to disable the flash.
FS#
Find Slide # (0 ≤ # ≤ 80)
Access slide in tray position #.
PF
Projector Forward
Advances tray position by one slide.
PR
Projector Reverse
Reverses tray position by one slide.
PH
Projector Home
Turns lamp off. Reverses tray until home sensor is reached, or until tray
has been reversed 81 times.
PWRON
Power On
Activates projector power manually.
PWROFF
Power Off
Returns projector power to automatic cycling.
