2 DETAILED DESCRIPTION
The transmitter is fitted in a battery (V-mount or AB) dockable unit able to be installed on every camera. All
connectors are standard and located on the right side of the unit. Audio and intercom connectors are located
at the rear of the unit along the battery.
A user panel feature LEDs for signal presence/activity, rotary button for volume adjustment and various level
settings (sidetone, program1 / program2 listen level) and push to talk commands. Red/green tally led are
located on top of the unit.
Cooling of the unit is done by a small and silent fan located at the back of the unit.
The basestation receiver is integrated in a standard 19” 1RU format. All signals are dispatched on standard
connectors and standard pinout at the rear of the chassis. (Web server is on a separate Ethernet port).
The front of the chassis is composed of a LED display panel indicating the status of each signals and
technical alarms. An Oled display gives direct access to optical receiving levels and server IP address.

2.3 CONNECTORS DESCRIPTION
Digital video, Composite video and Timecode I/O’s are on standard size BNC.
The pinout and specificities of the remaining connectors is detailed in the following sections.
2.3.1 SDI CHANNELS
3G channels supports from 270Mbs to 3Gbs, 12G channels supports from 270Mbs to 12Gbs.
All channels are reclocked and support RAW formats.
2.3.2 SDI MONITORING
Monitoring channel is transmitted by TDM along the other low datarate signals and supports only HD rates
(1.485GBs or 1.485/1.001 Gbs), the ANC part of the signal SDI is transmitted (Embedded audio etc).
At camera side the monitoring input can be either SDI or HDMI autosense. If both signals are fed to the
camera unit the selector will use the first valid signal detected.
Note: The HDMI audio is not re embedded in the Monitoring SDI signal transmitted to the basestation.

ERECA SAS 75 rue d'Orgemont, 95210 SAINT GRATIEN France Tel [phone] www.ereca.fr 2.3.3 ETHERNET PORTS Ethernet interfaces are 10-100 Mb/s autosense. The camera ports are both Auto Crossover and will work with any type of cables. The admin port is not Auto Crossover and will require a crossed cable to work directly with a computer. 2.3.4 COMPOSITE INPUT 1 SPECIFICITY This channel is mainly used for Genlocking the camera on the studio Black-Burst. In order to ease the distribution of Genlock to many cam racers by using BNC T’s only, the Composite 1 input impedance can be turned to High Impedance. To do so, go to the settings webpage of the units and tick the “High impedance for composite 1” on most of the cam racer’s. The last unit fed by the signal will remain with 75 Ohms input impedance (“High impedance
for composite 1” = unticked).
2.3.5 RJ45 DATA1 ON CAMERA HEAD The RJ 45 connector provide 1 differential pair for RS422 transmit and 1 differential pair for RS422 receive.
To build half duplex RS485 transmission just bridge pins 3 with pin 4 and pin 5 with pin 6.
Max bitrate is 500 Kbds. For RS485 also setup the corresponding Baud rate within the web server to enable the cam racer to manage output impedance at the right serial byte duration. Shorting pin 1 and 2 will trigger the Intercom for talking on channel 1. Pins 7 and 8 are shorted at camera side (Floating dry contact) when tally RED is triggered at base station.

2.5 REMOTE POWER SECTION
2.5.1 MAIN POWER SECTION
CAM Racer is basically remote powered from its base station. The basestation unit is able to source up to
140W of power for the camera at 450m of 9.2mm SMPTE cable. For longer runs the amount of available
power will decrease as shown on the following curve.
An optional battery support (V-lock or AB Gold mount) enables the CAM racer and its camera to be locally
powered by a battery.
A key feature of the Cam racer is the automatic switching between remote power and battery power without
power loss for the CAM racer and its camera. On very long lengths of SMPTE a temporary sudden extra
consumption (camera startup, accessory startup) may draw too much power regarding the loss of the
installed SMPTE cable. In this case the CAM racer will detect power drop and will switch on the battery and
come back on the remote power supply to save battery energy.
Note: The power curve above represents power dissipated by a pure resistive load, camera inrush current or
accessories inrush current may exceed those limits and make the internal converter to stop briefly and
restart. We improve our power section as converters with less load sensivity arrive on the market.
For this kind of application we suggest using our automatic battery backup principle.
2.5.2 8.4V REGULTATOR OPTION.
CAM racer is also designed for small power consumption devices like Canon C300/C500.
Upon request the remote power section is suppressed at both ends. The lock battery option powers the
Cam racer and fits an internal hi efficiency voltage regulator to deliver 8.4Volts 32Watts for the Canon
Camera over a dedicated D-Tap connector.
Upon request the 8.4V regulator can also be fitted on regular units with a dedicated D-TAP output.

2.6 AUDIO MIXER
The Cam racer basestation audio section provides a small mixer that enables to send to each internal audio
channel transmitted to the camera (Intercom1, Intercom2, Audio1, Audio2) a mix of the 6 physical input
sources (Intercom1, Intercom2, Pgm1, Pgm2, Audio1, Audio2).
Depending on the application, any user can hear the desired audio mix in his headset or earpiece.
This useful feature also avoids any complex cabling between an external audio mixer and the cam racer
basestations.
This setting is done within the “volume settings” section of the settings web page. A small mixer subset is
available for each audio going to the camera
To add a source to the mix, firstly tick the “reinject” box and secondly adjust the desired level.
For multiple setting, use the Download / Import configuration at the bottom of the settings pages to Save /
Recover settings from your computer.
2.7 INTERCOM BEHAVIOUR
Intercom have 2 operation modes:
• Singleheadsetwith2channels(Mostcommon).
• Separateheadsetwith1channeloneachheadset.
The selection is done with the combo box named “Intercom mode”
The Talk / Talk latch action can be done directly on the camera unit or trough ground closures located at
SERIAL 1 RJ45 or on the Hirose12 Multipin depending of the mode choosen.
Talk latch is enabled by pressing momentaneously (> 0.5 second) the talk button on the desired channel.
After this delay the unit will turn to simple Push to Talk and will close the channel upon button release.
2.7.1 2 CHANNELS INTERCOM
Talk command sources are:
• Cameraunitbutton(enabletalkonchannel1and/orchennel2),
• Serial1RJ45groundclosure(enabletalkonchannel1),
• GroundclosureontheHirose12connector(enabletalk on channel1).
By default or when talking on channel 1, the blue button rotation will adjust global listening level of the audio
mix programmed on channel 1. When talking on channel 2 rotating the blue button will adjust the channel 2
listening level without affecting the other levels heard in the headset.

2.7.2 SEPARATE INTERCOMS
Talk command sources are:
• Cameraunitbutton(enabletalkonIntercom1/channel1 and/or Intercom2/channel2),
• Serial1RJ45groundclosure(enabletalkonIntercom1/channel1),
• GroundclosureontheHirose12connector(enabletalk on Intercom2/channel2).
By default or when talking on Intercom1, the blue button rotation will adjust global listening level of the audio
mix programmed on intercom1.
When talking on Intercom2 rotating the blue button will adjust global listening level of the audio mix
programmed on intercom2.
3 WEB MANAGEMENT
Full control and setup of the Cam racer transmission can be done trough the web server. As described in
the previous sections some settings can be done directly on the units by the “blue” button, in this case the
buttons settings will take precedence on the web page control. When adjusting volume with the button the
corresponding fader will move on the webpage but is no more responsive to any change attempt made on
the web page for a small amount of time (1 second).
3.1 ESSENTIALS
The CAM RACER is monitored and configured through WEB interface. (Firefox web browser preferred).
The RJ45 Ethernet ADMIN port of the basestation provides access to the embedded web server interface.
Note this network have no relation with the remote camera remote Ethernet port.
The default web server interface IP add is 192.168.1.247.
A long press (5 seconds) on the Reset at the left of the admin Ethernet port will reset its configuration and
revert the default IP add.
The home page displays Red Tabs on it is upper part, giving access the different parts of the supervision:
• Status – Alarms: Provides the status of the signals and the alarm report of the product.
• Measures: Provides the details of the technical information of the product.
• Settings: To set Internal audio mixer, MIC input gains, Intercom modes….
• Configuration: To configure the IP address of the product and supervision settings.
Camera head unit have no internal web server, the whole link is monitored trough the basestation web
server. The basestation hold all the configuration, and updates the camera head module once the link is
established.

3.2 STATUS PAGE
Note that the screen is splitted in two parts, with basestation on the left and camera unit on the right.
Each sub page has its own set of status (dark blue groups) and its own set of alarms (dark red groups).
3.2.1 SIGNAL ACTIVITY
The homepage displays the status of each signal transmitted by the unit, the information reflected the unit
webpage is the same point of view as what happen on this unit connectors.
The signals are grouped in category easily recognizable thanks to the pictograms attached to each
category.
The video section is more detailed with the detected data rate colored indication Datarate is only recognized
on receiver’s channels.
3.2.2 ALARMS DISPLAY
The unit global technical status / alarm are summarized in the 3 lower categories:
• Powersupplyalarms(Powergoodstatus,internaltemperature over 60°C and fan defective
indication).
• DataFiberalarms(Opticalreceiverunsynchronized, Optical power monitoring on the Main
and spare fiber, Defective laser on Data transmitter).
• VideoFiberalarms(Opticalpowermonitoringanddefective laser on Video transmitter).

3.3 MEASURES PAGE
The "measures" page provides the detail of the product technical information.
3.3.1 GENERAL DETAILS
Provides detailed information of internal power supplies voltages / fan currents / temperature.
Figures are displayed in purple if all is OK and become red if the value is out of range (in this example the
camera module is not plugged on the basestation so its parameters are null displayed in red).
3.3.2 OPTICAL DETAILS
These two groups monitor the basestation and the camera unit optical state.
Each figure will change color if the alarm threshold is reached (60mA for the laser , < -18dBm for the 3G
optical receivers and < -13dBm for the 12G optical receivers).
The optical level below -18dBm (-13dBm) warns the user against a too high fiber attenuation or a dirty
connection, it does not mean that the signal will be lost (each receiver is tested to -20dBm(-15dBm)) but that
a connector cleaning or fiber trouble shoot has to be done on an asap basis.
The laser overcurrent is a preventive information, it indicates something wrong and that the unit need
service asap but should be still able to transmit data for the current event.
