General description The 3000 series switchers are a family of “smart” switchers in Eurocard format, which may be linked and configured by the user to cover a wide range of switching and monitoring functions. By combining modules, the user is able to easily assemble switchers ranging from a basic 5 x 1 to the equivalent of a small router, encompassing analogue and digital signals in multiple levels. These may be controlled with multiple local or remote control panels or under computer control.
Features of individual modules: TPS-3010: Local tally panel. Fits any switcher in the series. Equipped with 5 tally LED’s. Provides visual indication of switcher status when switcher is remotely controlled. AVS-3010: AVS-3011: Analogue video switch with looping inputs. Internal vertical interval switching or external synchronisation for use in RGB, YUV & YC applications. As for AVS-3010, but with wire per crosspoint input patching and improved static immunity.
CDC-3060: Logic control module. Performs a variety of functions according to the users (link selectable) choice. May be used directly or in conjunction with local or remote control switch panels. RS232 control address bits allow one computer serial port to control up to four CDC-3060’s with different addresses. Current output status is indicated on the return RS232 line for tally purposes. Sequential (cyclic) control.

Circuit description The 3000 series of switchers and controllers share a common logic control system. This system is therefore described separately and applies to all modules in the group unless otherwise indicated. The power supply system is similar in each module and is therefore described separately.
AAS-3020 & AAS-3021: (See diagrams 803754 & 804115 sheet 2.) The raw DC power is fed to three terminal regulator IC’s which provide ±12 Vdc rails for the audio circuits. The +12 Vdc is also supplied to the remote logic connector PL 4 pin 1 via a current limiting resistor R 34 for use by control panels. The 12 Vdc rails are further connected to two more three terminal regulator to provide the ±5 Vdc. The +5 Vdc is required by the logic control circuits and ±5 Vdc for the audio matrix switching IC’s.
Switching Logic: Control logic for each switcher module is performed by a Programmable Logic Array (PLA) which has been programmed for the required operations. This component will only function correctly when loaded with the correct program and is therefore only available through IRT. Each module of the switcher group has two control connectors on its rear assembly. They are labelled PL 4 and PL 5. For descriptive purposes, PL 4 is called the “input” connector and PL 5 the “output” connector.
Signal path: AVS-3010 & AVS-3011: Analogue video. Video path: (See diagrams 803614 & 804070 sheet 2) The incoming video signal on each of inputs 1 - 5 is connected to two BNC connectors on the rear assembly to provide a loop through capability. One of these terminals must be terminated in 75 Ω either via a termination plug or via other equipment. Inputs 1 - 5 are terminated in 10 KΩ in order to reduce noise from unused inputs. Cascade input PL3 (SMA connector) is terminated in 75Ω.
DDS-3030 & DDS-3031: RS422/RS485 data. (See diagrams 803763 & 804200 sheet 1) The RS422/RS485 data lines are bi-directional, consisting of a send and receive pair. Thus, it is not strictly correct to speak of inputs and outputs for this switcher. The switcher in essence connects a common transmit / receive pair to one of five other receive / transmit pairs.
Internal adjustments The following adjustable circuit elements are factory set and should not be adjusted unless a component has been changed. They are not 'operational' controls. Before adjusting any of these controls allow time for the module to reach temperature stability. AVS-3010 & AVS-3011: C8 RV 1 RV 2 Frequency response. Video gain. Vertical interval switching point delay adjust. Set to line 9. AAS-3020 & AAS-3021: RV 1 RV 1 Main board Sub-board Audio gain -- Right channel.
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.
Power on reset: Power on reset is needed so that at power on only one switcher or control panel drives the buss. LK 3 on each of the Switcher Group or the CPS-9000 / 9001 remote control panel is used to select which unit is in control at power on. If LK 3B is not installed and the switcher/control panel is configured to be for Inputs 1-5 then at power on that unit will take control of the buss and select input 1.
Switcher set ups larger than 5 x 1 10 x 1, 15 x 1 and 20 x 1 switchers can be made up of multiple switchers. In order to achieve this connections have to be made between modules for both control and signal purposes. In addition, links on each module need to be configured to set the address range for the module. These three operations are dealt with separately below. Control side: LK 1 and LK 2 on the switchers are used to assign the group of inputs that a module will switch.
AAS-3020 & AAS-3021 5 x 1 Stereo analogue audio switcher When the data buss value is outside the range of inputs for which the module is configured the module places its signal busses in a high impedance state. J 4L (on the motherboard) and J 4R (on the sub-board) are signal buss extender connectors. Therefore, by paralleling all the J 4L connectors on a group of switchers, and all the J 4R connectors, size expansion is achieved.
DVS-3040 & DVS-3011 5x 1 Serial digital switcher: When a DVS-3040/3041* is to be used for inputs greater than 1-5 two optional connectors PL 1 and PL 2 are installed on its motherboard. In addition, R 21 is moved to its alternative position. When the data buss value is outside the range of inputs for which the module is configured the module selects PL 2 (Expn In) on its motherboard as its input.
Program: The CDC-3060 has a microprocessor on board which can have four different operating programs loaded. Program selection is by links LK 4 (b 0) and LK 5 (b 1) as follows: Program Switcher Control Panel PR 3 PR 4 LK 5 -- b 1 OUT OUT IN IN LK 4 -- b 0 OUT IN OUT IN PR 3 & PR 4 are currently reserved for future use. Switcher program: The switcher program is used where the controller is to be connected to a switcher or group of switchers to actuate their function.
Cyclic control: In addition to the remote control capability, the local CDC-3060 logic control module also provides a “cycle inputs” function.. This may be activated locally or via the RS232 interface. In either case the controller must be pre-set with the start and end switcher crosspoint numbers and the time required to hold each input before stepping to the next in sequence. For example, the settings required may be: Start at input 2 End at input 7 Step every 5 seconds.
Address bits: If the RS232 address bits are an exact match for those on the CDC-3060 then the CDC-3060 will execute the command to activate the crosspoint or respond with the switcher tally status depending on the state of the command bit. If the RS232 address bits do not match those on the CDC-3060 then the CDC-3060 will ignore the instruction as far as any attached switcher is concerned and will repeat the instruction on its TXD line for forwarding to any other CDC-3060’s connected.
Wire per crosspoint operation In most cases, the BCD encoded remote control system offers the most satisfactory way of controlling one or more switchers. There are however, situations where it is necessary to provide a wire per crosspoint access for control and / or a line per crosspoint tally system. Both of these facilities may be made available on the 3000 series in a number of ways.
Pin numbering is as follows: Pin Signal 1. GND reference (LK 3A connected) 2. Switch 1 contact 3. Tally out 1 4. Switch 2 contact 5. Tally out 2 6. Switch 3 contact 7. Tally out 3 8. Switch 4 contact 9. Tally out 4 10. Switch 5 contact 11. Tally out 5 12. +5 Vdc 560 Ω sourced feed for tally LED’s. Tally lines are pulled low when active and an indicating LED may be directly connected between the pin 12 current source and the tally line for each crosspoint.
External BCD encoding: The switching logic for the 3000 series is a binary sequence as explained under Switching Logic. Where wire per crosspoint style operation is required, the following simple method may be used to externally encode wire per crosspoint signals into the BCD format required by the switcher input. PL 4 Pin Regulator IC Type 78L05 Crosspoint 1 +12 Vdc 1A Unlatch in +5 Vdc 5B Gnd 1B Data 0 4A Data 1 3B Data 2 3A No connection required.

Operation CDC-3060: Cyclic control. The CDC-3060 will perform automatic cycling of inputs of selected switchers on demand. This can be performed at any time and will continue until a stop command is given by local, remote or RS232 control. The first and last inputs between which the switcher will cycle are set by switches on the CDC-3060. See Configuration section for details. To Start cycling: Press any button on a local or remote control panel for more than 2 seconds. or Send code 1F via RS232 link.
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.
