Product Description The CameraMan Student Camera System is a
robotic camera system with distributed preset con-
trol used in distance learning applications. This sys-
tem gives each student the power to be instantly
identified by the camera with the touch of a locator
button on a microphone.
The Student Camera System can store up to 125
Location Presets, 33 of which are connected to the
Programmable Response Module. The 33 Student
Locations are accessible through the Low Profile

Microphones and the Camera Control Keypad. The
other 92 Location Presets are only accessible
through the Camera Control Keypad.
In standard distance learning rooms, the camera is
set to a wide-angle view of the classroom through-
out the lesson. This makes it difficult for instructors
at the far-end to differentiate one student from the
next and determine exactly which student is speak-
ing. With CameraMan, each individual student can
simply press the “My Turn” button on a microphone
when they want to speak. The camera will then pan,
tilt and zoom in on the individual student, magnifying
their image.
When the student is finished speaking, the student
simply releases the “My Turn” button and the cam-
era returns to a wide-angle view of the classroom.
This allows instructors at the far-end to identify each
student individually and have face-to-face interac-
tion. Building these one-on-one relationships will
enhance the overall learning process, making dis-
tance learning more responsive and effective.
Your Student Camera System should include
these components:
•One 1-CCD or 3-CCD Camera Control Keypad
•One Programmable Response Module
•One Programmable Response Module Power
Supply
•One 10’ CameraMan Communication Cable
•One CameraMan RS-485 Connector “T”
•One 3’ CameraMan Communication Cable
•One Student Camera System Operations Man-
ual
•One Camera Control Keypad Card (1CCD or

System Components
Your Student Camera System includes a Program-
mable Response Module, Power Supply, a 1-CCD
or 3-CCD Camera Control Keypad, and connection
accessories. To set up your system, you will also
need an audio mixer and microphones which may
be purchased separately through Grass Valley.
Programmable
Response Module
FIGURE 1.1 Front of Programmable Response
Module (PRM)
The Programmable Response Module (PRM) is
designed to provide automated camera control of a
student camera in a classroom environment.
Through the use of “press-to-talk” microphones, the
camera can be automatically positioned on an indi-
vidual student when they wish to speak.
Grass Valley’s Low Profile Microphones are recom-
mended for better camera control. “Voice-activated”
microphones may pick up background noise and
cause unwanted camera motion.
The PRM works on a first-come, first-served basis,
so when two or more students activate their micro-
phones at the same time, the first microphone acti-
vated will get control of the camera. Once a student
has activated the camera, all others are LOCKED
out, except the master override microphone. When
the student is finished speaking, the PRM will take
the next microphone in line. After all the micro-
phones become inactive, the camera will return to a
wide-angle shot of the classroom. This can be cus-
tomized and is stored in Location Preset #2.

The PRM Power Supply and CameraMan Power
Supply should not be interchanged.
ConnectingMicrophones
to the PRM
1. Place the microphones around the room, and
label them accordingly (i.e.: numbered 1, 2, 3,
etc.)
2. Connect the microphone via the appropriate
length microphone extension cable (not
included) to the optional microphone “Y” Cable
(5-pin mini XLR to 3-pin male XLR/2-pin female
Phoenix connector).
3. Connect 3-pin male XLR to your room’s micro-
phone mixer/phantom power source.
4. Connect the 2-pin female Phoenix Connector
(green connector block) to the appropriately
labeled PRM input (i.e.: 1, 2, 3, etc).
5. Repeat steps 2-4 for all remaining microphones.
If you are using non-Grass Valley supplied “Y”
Cables, follow these instructions to connect the 2-
pin female Phoenix Connector wires to the green
connector block:
1. Strip a short section (approximately 0.15”) off the
end of the wire.
2. Insert the wire into the screw terminal slot on the
connector plug.
3. Tighten the terminal screw.
4. Repeat steps 1-3 for the other 4 wire-pairs in that
connector block.
If you are using microphones which are polarity sen-
sitive, the inputs should be wired as follows:
1. The positive lead, from the contact closure of the
microphone, should be wired to the top input of
the pair, labeled “+”.
2. The negative lead, from the contact closure of
the microphone, should be wired to the lower
input of the pair, labeled “-”.
All of the inputs labeled “-” are wired together inter-
nally and connected to ground.

Connecting the PRM to
the CameraMan
Using a 4-conductor cable, wired in a “straight-
through” mode and terminated with modular hand-
set connectors, connect the RS-485 port on the
back of the PRM to the RS-485 port on the back of
the CameraMan Camera.
FIGURE 2.1 PRM Connected to CameraMan
Connecting the Contact
Closure Outputs
The PRM’s AUDIO RELAY and VIDEO RELAY con-
tact closure ouputs are activated when a “press-to-
talk” microphone button is pressed, and deactivated
when the button is pressed again.
AUDIO RELAY
The intended application of this relay is to activate
the mute switch of the audio system in the room to
prevent feedback when the microphone is active.
The relay activates and the contacts close only
when a microphone button is pressed. In a typical
application, the Audio Relay contact closure would
connect to an amplifier or audio switcher.
VIDEO RELAY
The intended application of this relay is to activate a
video switcher to select between various video
sources. The relay activates and the contacts close
only when a microphone button is pressed. When
the contact relay is closed, there is a two second
delay to allow time for camera movement before the
video is switched. In a typical application, the Video

Chapter 2
12 CameraMan 1-CCD and 3-CCD Student Camera System Installation and Operations
Relay contact closure would connect to a video
switcher.
To Connect the Audio, or Video Relay:
1. Connect one end of a 2-conductor cable to the
green connector block:
•Strip a short section (approximately 0.15”)
off the end of the wire
•Insert the wire into the AUDIO RELAY or
VIDEO RELAY screw terminal slot on the
connector block to the far right (the positive
“+” lead is on top, the negative “-” lead is
on the bottom
•Tighten the terminal screw
2. Connect the other end of the cable to your audio
equipment per their instructions.

Configuring the PRM
The PRM POWER switch should be turned OFF
before changing any switches.
BASE UNIT ADDRESS:
This switch tells the PRM which camera it controls.
Set this switch to correspond with the BASE UNIT
ADDRESS switch on the back of the CameraMan
Student Camera (i.e.: If the camera’s BASE UNIT
ADDRESS is set to 0, set the PRM’s BASE UNIT
ADDRESS switch to 0). This address MUST BE dif-
ferent from the PRM Address.
PRM ADDRESS:
This switch is only accessible by removing the top
panel of the PRM. It is used to set the address at
which the PRM will reside on the RS-485 bus. This
should be set to an address that is unique to all
devices (cameras, PRMs, etc) in the system. By
default, the address is set to “C”. This address
MUST BE different from the Base Unit Address.
