Overview

Thank you for purchasing this Bluebell Opticom professional broadcast video product. If you are

new to Bluebell products, or to the subject of transmitting video and/or other types of signal over

bre links, please take the time to read through this document before putting the card to use.

Introduction

The BC780, BC785T and BC785R plug-in cards belong to the range of the Bluebell Opticom

BC Series modular bre interfaces, designed primarily for Outside Broadcast (OB) and studio

applications. The cards have been designed for the transport of control commands or similar

data over a bre-optic link: a typical use would be to control and synchronise video cameras

installed at remote locations, as may be the case at large-scale sporting events, music festivals

and similar OB situations.

All three card types cater for control data in the following formats:

• 10/100base-T Ethernet

• RS-232

• RS-422

• RS-485

Cards will normally be used in pairs, one being installed at the control centre end (base station)

and the other at the remote end (camera station). The cards are bidirectional, so that control

response data such as command conrmations or status reports may be received by the

controlling equipment at the base station.

A general purpose input (GPI) and general purpose output (GPO) are also provided, to allow a

contact closure-generated command to be transmitted in both directions.

Card types BC785T and BC785R have the additional capability of handling a video genlock

signal as well as the control data formats listed above. The BC785T has a BNC genlock input

and the BC785R a BNC genlock output: again these two card types are intended to be used in

pairs, with the BC785T at the base station end and the BC785R adjacent to the camera.

All card types are equipped with a dual SFP carrier: this will generally be tted with a bre-optic

transceiver cartridge of the user’s choice, pre-installed by Bluebell Opticom according to the

user’s requirements (specied at time of order). An alternative option is for the carrier to be

supplied empty, so that it can be retrotted with a cartridge by the user.

Singlemode operation will normally be at 1310 nm or 1550 nm; alternative CWDM grid

wavelengths are also possible. The optical option is generally specied at the time of order. The

optical receiver will be wideband.

Physical format

BC780, BC785T and BC785R cards t the Bluebell BC100i and BC160i 19” modular frames.

These frames can house fteen (BC100i) or six (BC160i) interface cards, and are tted with

dual internal AC power supplies. The cards are also compatible with earlier Bluebell 19” modular

frame types BC100 and BC160.

Alternatively, cards may be tted into smaller aluminium chassis: the BC101 and BC102 hold

one and two cards respectively and require an external DC power source, while the BC120 holds

three cards and has an integral mains PSU.

Power requirements

Power supply requirements are dictated by the enclosure type used.

BC100i modular frame:

This is normally tted with two identical AC mains PSU modules. Each module has sufcient

capacity to power a fully-loaded frame. The AC connection is via standard IEC cables, DC power

distribution inside the frame is via the motherboard. See the Operation Guide supplied with the

frame for more details.

BC160i modular frame:

This is tted as standard with dual internal AC mains power supplies, each of sufcient capacity

to power a fully-loaded frame. The AC connection is via standard IEC cables, DC power

distribution inside the frame is via the motherboard. See the Operation Guide supplied with the

frame for more details.

BC101 and BC102 single- and dual-slot chassis:

These are supplied with an external Universal AC adaptor which connects to the chassis via a

flying lead terminated in a 4-pin locking XLR connector. Mains connection is via an IEC connector.

BC120 triple-slot chassis:

This housing for three plug-in modules is tted with an internal AC mains supply; mains

connection is via a rear IEC connector.ts.

1. SFP – SFP carrier for optical input and output. User’s choice of transceiver cartridge may

be tted. The lower optical connector is “receive”, that is, an input to the module, while the

upper connector is “transmit”, an output from the module.

2. S/L – bi-colour LED shows received data status. The LED illuminates green to indicate that

valid data is detected at the SFP Rx port, and red when no valid signal is detected. “Data” in

this context includes both Ethernet data and serial control commands/responses.

3. ETHERNET – Standard RJ45 Ethernet network port for transmission/reception of control

data in Ethernet format. Auto-switches between 10base-T and 100base-T data rates.

4. DATA I/O – 15-pin female Dsub connector for serial control data to RS-232, RS-422 or RS-

485 standards. Also provides GPIO connectivity. The pinout of this connector is as follows:

For bidirectional operation, the SFP carrier must be tted with a transceiver cartridge and

dual bres used. If no return data is required from the remote location, a single bre may be

employed, with a single channel optical transmitter cartridge in the base station BC780 and

a single channel optical receiver cartridge in the remote BC780.

The control data format in use – Ethernet, RS-232, RS-422 or RS-485 – will be determined

by the camera and associated control equipment: the BC780 is capable of transporting both

Ethernet and serial data in multiple formats, together with GPIO signals if needed, over the

bre link simultaneously. (However note that it is not possible to transmit/receive RS-422 and

RS-485 data at the same time as these formats use the same pins on the Dsub connector.)

Control data applied to the BC780 in all formats is buffered and multiplexed onto the optical

carrier. With a pair of BC780 cards, a second, symmetrical signal path is available in the

opposite direction, as the diagram above shows.

The signal processing for these cards is identical to that of the BC780, with the addition of

the ability to add an analogue video genlock signal to the multiplexed control data being sent

via the bre link. The BC785T has a genlock input and the BC785R a corresponding genlock

output. Clearly, the signal path for the genlock signal is only unidirectional: base station to

camera.
