Diver Communications
The diver audio is standard set for a 2 wire communications (simplex).
The divers can only speak to each other when the surface operator pushes the cross-talk switch to the desired direction.
The SCU-2DRVL can also be set for 4 wire communication (duplex)
The divers have an open 2 way communications with each other without any selection from the surface. The surface will
hear both divers and can talk to the desired diver by pressing the corresponding PTT. Also can the comms be set for
Full duplex. The there is a full open communication (conference) between the divers and surface.
9.2.1 2 wire comms configuration
The SCU-2DRVL is standard fitted with a 10 pin multipin connector.
The audio comms for 2 wire comms is connected to the diver umbilical via the multipin
connector (pins H,J) or via the yellow Banana sockets
9.2.2 4 wire comms configuration
The SCU-2DRVL is standard fitted with a 10 pin multipin connector.
The audio comms for 4 is connected to the diver umbilical via the multipin connector (pins
H,J,G,K) or via the yellow and blue Banana sockets
9.2.3 Comms Mode
The Comms Mode is a selection comms mode switch. This allows the use of a 4 wire
comms system and still be able also to use the system as a 2 wire system.
The 4 wire configurations has 3 user modes:
2S - 2 or 4 wire simplex
4HD- 4 wire Half duplex surface to diver, full duplex diver to diver
4FD- 4 wire Full duplex, surface and divers full duplex without any PTT
9.2.4 2/4S - 2 wire simplex
This mode is the same as the standard comms when using 2 wire. This works with either 2 or 4 wires comms cable
configuration. The diver will always be heard at the surface and the Tender needs to push the PTT switch to talk to
the diver. The divers can only speak to each other when the Tender uses the Cross to Talk switch from diver 1 to
diver 2 and vice versa.
9.2.5 4HD – 4 wire Half Duplex
This mode uses a 4 wire comms cable configuration. In this mode the divers can speak with each other without any
control from the Tender. The Tender will hear both.
The Tender needs to push the PTT button to speak to the divers.
9.2.6 4FD- 4 wire Full Duplex
This mode allows to have a full open communication between divers and Tender to divers without using the PTT
buttons. Like a conference call.

9.8.1.2 How it works
With novaNET controls you can control cameras & lights from any SCU or SCC unit within the network. Each
camera & light is addressed with CH1 up to CH16. This is set during manufacturing. There will be always be
one unique address 1. But address 1 (CH1) with the belonging camera and light can be controlled from more
than one SCC/SCU unit. All works in parallel, with overrule from the last SCC/SCU control command send.
This means you can switch on the camera with the switch on the SCU-1DRVL and switch it off with a SCU-
DVR2. The switch on the SCU-1DRVL is still in the on position but the LED on the switch will be off. You can
switch on again with the SCU-DVR2 by pressing on CAM or with the SCU-1DRVL by toggling the switch off
and on again. The same is for the lights.
If you switch on from a SCU-DVR2 or from the NovasubDVR software, the LED in the swith will lid up, even if
the switch on the SCU-1DRVL is in off position.

Camera and light control
The camera and light are switched on with rocker switches. Both have a LED indicating that power is supplied to the
camera and light. The light intensity can be controlled with rotation Knob.
10.2.1 Camera signal
The SCC has a built in auto tunable video line driver for each camera. This video line driver allows the use of video
signal over twisted pair or coax cable up to a maximum length of 600 m. Also the line driver can be set for coax
cable use.
The Novasub cameras are available with video line driver for video signal over twisted pair and coax.
The Novasub cameras set for Twisted Pair can also be used on Coaxial umbilical’s or cables.
The power supply to the camera is standard 32 Vdc, if required the voltage can be set to 12, 15 or 24 Vdc. This is a
factory setting.*
*Only on order of SCU-2DRVL.
10.2.1.1 Why use video transmission over Twisted pair
Novasub has developed video transmission converters that makes it possible to transfer a video composite
signal over a standard twisted pair cable. The latest converters are Auto tuneable for cable length up to 600
m. All standard Novasub camera and topside control units have these video transmission converters built in.
The cameras have a composite video to twisted pair signal transmitter, and the topside units have a twisted
pair signal to composite video receiver.
All Novasub cables and umbilical’s, are standard fitted with screened twisted pairs (STP). These STP are used
for all possible data/audio and video transmission.
Novasub does not use Coax for video signal transmission. The reason is the mainly weak and interference
sensitive Coax cable.
NOVASUB umbilical and cable uses video signal transmission over shielded twisted-pairs (STP).
The advantages of twisted-pair are;
more reliable video transmission through less interference( electromechanical- or radio frequency
interference)
higher movability through higher flexibility
STP is a stronger cable then coax
higher flexibility in applications, twisted-pair cabling is the standard in data transfer worldwide
easier to install/repair/handle
10.2.2 Light controller
The SCU-2DRVL is standard fitted with a LED light controller that matches the Novasub LUX3 and LUX6 lights.
The LED controller regulates the Ampere from 0-1,6 A at 32 vdc.
An Halogen light bulb up to max. 25/30 watts can also be controlled directly from the LED-controller.
Also other brands of LED light can be controlled, however they need to be internal protected against a max.of 1,6
Amp. Current and a 32 Vdc voltage.
If required the max. output Ampere can be set to a lower and higher value. This is a factory setting.
Switch on the
Camera
Press the camera switch to the right, the CAM green LED
switches on.
Switch on the
Light
Press the light switch to the right, the green LED indicates
that the light is powered. Increase and decrease light
intensity with the Yellow knob.
Remote
Control
When a SCU-DVR2 or SCU-PCDVR04 is connected via the
novaNet Bus, then the camera and light switching and light
control can also be realized from the Keypad of the SCU-
DVR2 or Novasub-DVR software.
