5.01 Camera Control Data

NightRunner cameras are controlled via an RS485 serial data

connection, using a variant of the Pelco-D CCTV camera control

protocol. The Pelco-D protocol was designed to provide

accurate controls for a wide range of standard CCTV features,

such as pan, tilt, user preset features etc, but do not include

certain extended features supported by Iris cameras. Because

of this, Iris have mapped their product speciﬁc features to

certain user preset commands and to other modiﬁed Pelco-D

commands. This means that NightRunner cameras can be

controlled either by a dedicated NightRunner joystick controller

such as the IRIS595 or Irisʼs IRIS516 (v2), as well as other

control devices, such as compatible chart-plotters, multi-

functional displays and third party joysticks. For further

information on compatible third party control interfacing please

contact Iris Innovations. For certain third party interfacing,

additional serial protocol convertors may be required where

NMEA0183 or NMEA2000 connections are used. Details of the

Pelco-D commands mapped for Thermal Camera functions are

included in this document.

5.02 Cabling Requirements

NightRunner utilizes a unique, new cabling system designed to

simplify most installations and therefore cut cabling and install

costs.

The camera features a single, water resistant RJ45 socket into

which power, video and control data are fed via a single

waterproof CAT5 cable (supplied). An active balun adapter is

supplied to connect to the other end of the CAT5 cable. Into the

balun, DC power is fed, composite video is output and RS485

control data from the controller is fed. See Diagram Below:

WARNING!

Due to voltage drop and the associated increase in current draw,

power must be introduced no further than 50ft from the camera

when using CAT5 cable. If the 60ft CAT5 cable supplied is not

long enough, power must be run separately or taken from a

source local to where the 60ft NightRunner cable ends. See

Section 5.07 Extending Cable Length for further details.

NEVER USE CAT5 CROSS OVER CABLE WHEN RUNNING

YOUR OWN CABLE. SEE APPENDIX B FOR FURTHER

DETAILS

5.03 Video Connections

NightRunnersʼ video output is a 1VP~P Composite video signal

compatible with most Multifunctional Displays (MFDʼs) and TVʼs

(via AV input).

The balun adapter features a male BNC connector for the video

signal, and NightRunner is supplied with a pre-made 2 meter

extension cable. Iris supply a range of pre-made extension

cables if required, alternatively, iʼve you wish to make your own

cable use 75Ω Coaxial cable such as RG59. Please note, RG59

has a solid core conductor which may not be suitable. In this

case use a stranded coaxial cable such as URM70.

A BNC ʻstraight-thruʼ adapter is supplied with NightRunner in

case you need to extend the video cable run.

As well as pre-made cables, Iris supply a range of connectors,

tools and adapter plugs. Contact your Iris dealer for further

information.

Many Multifunctional Displays (MFDʼs) / Chart Plotters use RCA

(Phono) jacks for video inputs. NightRunner is supplied with a

BNC/RCA adapter for this eventuality.

5.04 Data Connections

Control commands are sent to NightRunner over an RS485

Serial Data connection which has 2 wires usually labelled either

A and B or + and -. The data wires from the NightRunner balun

are identiﬁed accordingly:

White:! RS485 A (RS485+)

Braid:! RS485 B (RS485-)

When connecting directly to an IRIS595 or IRIS516 controller,

observe the following polarity:

Balun

Function

Controller

White

RS485 A (+)

Green

Braid

RS485 A (-)

White

Note

One of the most common faults when connecting data is

incorrect polarity. In the event that there is no camera control

when you have connected up, please check the polarity of the

data wires. You cannot damage the equipment by reversing

polarity of the data wires.

5.05 Connecting Multiple Cameras / Controllers

If your system features multiple cameras and / or controllers it is

advisable to use a Serial Data Distributor. Iris supply a range of

data distributors as listed below:

Part Number

Inputs

Outputs

EXP0204

EXP0208

EXP0216

Controllers are referred to as Inputs and cameras are referred to

as outputs. If you require more than 2 controller inputs contact

Iris for details of how to conﬁgure your system.
