Operational Safety: WARNING Operation of electronic equipment involves the use of voltages and currents that may be dangerous to human life. Note that under certain conditions dangerous potentials may exist in some circuits when power controls are in the OFF position. Maintenance personnel should observe all safety regulations. Do not make any adjustments inside equipment with power ON unless proper precautions are observed. All internal adjustments should only be made by suitably qualified personnel. All operational adjustments are available externally without the need for removing covers or use of extender cards. 3250-adc & 3250-dac.ib.rev3.doc Page 2 of 12 31/08/2007 IRT Eurocard Types ADC-3250/OPT & DAC-3250/OPT Analogue Video & Audio to 270 Mb/s Fibre Optic Link General Description The ADC-3250/OPT and DAC-3250/OPT form an encoder / decoder pair for converting an analogue video, up to 4 channels of audio and an RS-232 data port to a 270 Mb/s digital signal suitable for transport over ASI/SDI paths. This allows analogue signals to be passed through purely digital environments such as digital optical links and digital routers and switchers thus simplifying installations that are predominantly digital where some analogue signals still exist. When used with IRT’s fibre mux/demux system, both analogue and digital signals can be sent over the same link. The ADC-3250/OPT encodes the analogue input signals to a 270 Mb/s digital stream. The inputs can either be a single video, up to 4 channels of audio or a combination of video and audio. There is also an RS-232 data input port, which can be used concurrently with the video and audio or by itself. The DAC-3250/OPT decodes the 270 Mb/s digital stream to recover the original signals. Front panel LED indicators on both units indicate the presence of the analogue and data input signals. The ADC-3250/OPT allows cable equalisation of various lengths by a front panel control. A front panel monitor output aids in setting this correctly. Plug-in fibre optic boards are included on both the ADC-3250/OPT and DAC-3250/OPT for direct connection to a single mode fibre. The 270 Mb/s digital signal is of the same data rate as ASI and SDI signals hence its ability to be sent over ASI/SDI paths. Although similar in structure to both ASI and SDI it is neither of these types of signals. Hence the ADC-3250/OPT and DAC-3250/OPT are designed to act as an encoder / decoder pair. Both the ADC-3250/OPT and DAC-3250/OPT are manufactured on extended Eurocard boards and are suitable for mounting in IRT’s 1RU and 3RU Eurocard frames with other analogue or digital modules. Standard features: • • 1 analogue video, 4 audio and 1 data channel to 270 Mb/s digital stream suitable for transmission over 270 Mb/s systems, such as digital fibre systems, routers, etc. Plug-in Fibre Optic Link boards included.

Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures should be followed when inserting or removing cards from these bags. Power: AC mains supply: Ensure that operating voltage of unit and local supply voltage match and that correct rating fuse is installed for local supply. DC supply: Ensure that the correct polarity is observed and that DC supply voltage is maintained within the operating range specified. Earthing: The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure that the frame is connected to earth for safety reasons. See frame manual for details. Signal earth: For safety reasons a connection is made between signal earth and chassis earth. No attempt should be made to break this connection. Installation in frame or chassis: See details in separate manual for selected frame type. Connections: ADC-3250/OPT: Video Input The ADC-3250/OPT Video In port on the rear assembly is a 75Ω terminated BNC connector for analogue video only. Use of high quality 75Ω coaxial cable is recommended. Input equalisation and gain are set via front panel controls. Video Mon A front panel 75Ω output impedance analogue video monitoring port is provided for monitoring of input signal whilst adjusting front panel gain and equalisation controls. 270 Mb/s Output The ADC-3250/OPT Output port on the rear assembly is a 75Ω output impedance BNC connector, which has a 270 Mb/s encoded signal suitable for connection to an ASI or SDI circuit. Use of high quality coaxial cable such as Belden 8285, or equivalent, is recommended. 270 Mb/s Optical Output An optical output is available via the rear assembly fibre optic connector. The standard optical connector is an SC/PC type of connector for connection to single mode fibre terminated with the same SC/PC type of connector. If unit is ordered with a different type of connector, be sure that fibre is terminated with the suitable mating type of connector. Audio Inputs Four high impedance balanced audio inputs are provided via phoenix style 3-pin plugs labelled as Left Audio 1, Right Audio 1, Left Audio 2 and Right Audio 2. As per standard audio wiring standards, pin 1 is ground, pin 2 is (+) and pin 3 is (-). On board link settings allow direct connection to 600Ω systems. 3 (–) 2 (+) 1 (GND) 3250-adc & 3250-dac.ib.rev3.doc Page 6 of 12 31/08/2007 Alarm Outputs Two relay alarm output states are provided via a phoenix style 4-pin plug. Pin 1 is designated as Major, pin 2 is designated as Minor, and both pins 3 & 4 are ground. Although alarms are designated as Major and Minor, it is probably better to think of them as Alarm 1 and Alarm 2. Alarm conditions are as follows: Major switch to Open Circuit on no video input, or loss of power; Minor with on board switch SW1-1 on, switch to Open Circuit on no audio input, or loss of power, with on board switch SW1-1 off and optional fibre driver board fitted, switch to Open Circuit on laser failure, or loss of power. 4 GND 3 GND 2 Minor 1 Major RS-232 Data Input The RS-232 data input port is via a 10 pin HE14 style of header. Pins 1, 2 and 7 are connected together on the PCB. Pins 9 and 10 are both earthed. Pin 5 is the RS-232 request to send (RTS) connection and pin 6 is the RS-232 transmit data (TXD) connection. Data rates may be up to 115200 Baud. Note that data transfer is unidirectional only, i.e. there is no direct data return path. For connection to a standard RS-232 9 pin D connector, wire as per the diagram below: 9 Pin D Connector RS-232 1 CD 2 RXD 3 TXD CTS 5 7 4 RTS TXD 6 CTS 8 DTR RI GND 9 10 1 6 2 7 3 8 4 9 5 Ribbon Cable DAC-3250/OPT: 270 Mb/s Input The DAC-3250/OPT Input port on the rear assembly is a 75Ω terminated BNC connector for a 270 Mb/s ADC-3250/OPT encoded signal only. Use of high quality coaxial cable such as Belden 1505A, 8281, or equivalent, is recommended. 270 Mb/s Optical Input The optical input signal should be connected to the rear assembly fibre optic connector. Ensure that link LK4 is fitted to use optical input rather than electrical (coaxial) input. The standard optical connector is an SC/PC type of connector for connection to single mode fibre terminated with the same SC/PC type of connector. If unit is ordered with a different type of connector, be sure that fibre is terminated with the suitable mating type of connector. Video Output The DAC-3250/OPT Video Out port on the rear assembly is a 75Ω output impedance BNC connector, which has the decoded analogue video signal. Audio Outputs Four balanced low impedance audio outputs are provided via phoenix style 3-pin plugs labelled as Left Audio 1, Right Audio 1, Left Audio 2 and Right Audio 2. As per standard audio wiring standards, pin 1 is ground, pin 2 is (+) and pin 3 is (-). 3 (–) 2 (+) 1 (GND) 3250-adc & 3250-dac.ib.rev3.doc Page 7 of 12 31/08/2007 Alarm Outputs Two relay alarm output states are provided via a phoenix style 4-pin plug. Pin 1 is designated as Major, pin 2 is designated as Minor, and both pins 3 & 4 are ground. Although alarms are designated as Major and Minor, it is probably better to think of them as Alarm 1 and Alarm 2. Alarm conditions are as follows: Major switch to Open Circuit on loss of selected link input (optical or electrical), or loss of power; Minor switch to Open Circuit if no encoded video present*, or loss of power. 4 GND 3 GND 2 Minor 1 Major * Note: If no video is inputted to the ADC-3250/OPT, system will still work with only audio present. RS-232 Data Output The RS-232 data output port is via a 10 pin HE14 style of header. Pins 1, 2 and 7 are connected together on the PCB. Pins 9 and 10 are both earthed. Pin 3 is the RS-232 receive data (RXD) connection, pin 4 is the RS-232 request to send (RTS) connection and pin 6 is the RS-232 clear to send (CTS) connection. Data transfer is unidirectional only, this is a receive path only. For connection to a standard RS-232 9 pin D connector, wire as per the diagram below: 9 Pin D Connector RS-232 1 CD 2 RXD RXD RTS CTS 3 5 7 4 RTS TXD 6 CTS 8 DTR RI GND 9 10 1 6 2 7 3 8 4 9 5 Ribbon Cable Unbalanced Audio Operation Audio inputs and outputs are balanced by default, however it is possible to wire the audio connectors for use with equipment using unbalanced interfaces. On the ADC-3250/OPT connect the common (or shield) cable to pin 1 of the input audio connector, and the signal cable to either pin 2 or pin 3, but not both, of the audio connector. The unused pin, whether it be pin 2 or pin 3, connect to pin 1. 3 (–) 2 (+) 3 (–) or 2 (+) 1 (GND) 1 (GND) ADC-3250/OPT unbalanced input wiring On the DAC-3250/OPT connect the common (or shield) cable to pin 1 of the corresponding output audio connector, and the signal cable to either pin 2 or pin 3, depending on what pin the signal cable was connected to on the encoder. DO NOT ground the unused pin. Leave the unused pin unconnected; else damage may occur to the audio driver chip. 3 (–) 2 (+) or 3 (–) 2 (+) 1 (GND) 1 (GND) DAC-3250/OPT unbalanced output wiring 3250-adc & 3250-dac.ib.rev3.doc Page 8 of 12 31/08/2007 Front & rear panel connector diagrams The following front panel and rear assembly drawings are not to scale and are intended to show connection order and approximate layout only.

As with ASI signals, the 270 Mb/s output signal is phase dependent and so should only be used with noninverting links. Note that if the system is intended for audio or data use only, it is not necessary to also supply an input video signal, as all inputs are independent of each other. With the link and switch settings correctly set as in the configuration section of this manual, and input and output connections correctly wired and cards installed in a suitable frame as in the installation section of this manual, operation is as simple as connect and turn on. Front panel LED’s on both the ADC-3250/OPT and DAC-3250/OPT indicate the presence of what inputs are connected to the ADC-3250/OPT. The DAC-3250/OPT also indicates the presence of a suitably encoded 270 Mb/s stream. If the optional optical sub board is also fitted to the ADC-3250/OPT, a front panel LED also indicates if there is a laser failure. Adjustments With an ADC-3250/OPT & DAC-3250/OPT pair there is unity gain between the ADC-3250/OPT inputs and the DAC-3250/OPT outputs. The only user operational settings are on the ADC-3250/OPT front panel for compensating the analogue video for input cable losses. With a waveform monitor connected to the Video Mon BNC connector on the front panel, input a known test signal such as colour bars down the intended input cable. Adjusting both the gain and equalisation controls through the front panel, using a small flat bladed tweaking screwdriver, can compensate for loss of gain and frequency roll off caused by the length of input coaxial cable. 3250-adc & 3250-dac.ib.rev3.doc Page 10 of 12 31/08/2007 Maintenance & storage Maintenance: No regular maintenance is required. Care however should be taken to ensure that all connectors are kept clean and free from contamination of any kind. This is especially important in fibre optic equipment where cleanliness of optical connections is critical to performance. Storage: If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be included to deter corrosion. Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures should be followed when inserting or removing cards from these bags.
