ACO-2200 User Guide (v5.0) Before You Begin • 9
Before You Begin
The ACO-2200 is designed for high reliability Master Sync operations where two SRG-2200 units are provided as
a fail-safe Primary and Backup pair. The ACO-2200 provides automatic fail over to the wide range of SRG-2200
reference signals.
The ACO-2200 provides user-selection of reference sources. Automatic changeover may occur upon fault detection
in any active source.
The ACO-2200 is an in-line device without internal buffers. Switching for all channels is by mechanical relay. The
ACO-2200 also provides internal termination for unswitched BNC inputs.
The ACO-2200 includes 6 channels in a 1U rack. Each BNC channel consists of a Primary Input, a Backup Input,
and an Output. All BNC channel relays switch in unison upon fault detection in any active BNC channel,
front-panel command, or remote command.
The ACO-2200 uses signal amplitude as the basis for error checking. You can configure each BNC channel to
check for a different type of input. There is a selection of predefined checking levels relating to the various signals
that are supported:
• No Measurement
• Color Black (no ancillary signals present, i.e. only Sync and Burst)
• Color Black + VITC (with one or some ancillary signals present)
• 600mV Tri Sync
• SD SDI - LOS
• HD SDI - LOS
•3GSDI-LOS
• 1V 10MHz
• 1V Sub-carrier
•1VAES
•2VPulses-LOS
•4VPulses-LOS
For the common signals, a fault is reported when the input signal level falls below a predetermined ratio of the
nominal peak value. Visual fault indications appear on the front-panel display for signals from both the Primary and
Backup SRG-2200s. These indications remain on until cleared by the operator.
The signal reference amplitudes used for fault detection are programmed during factory calibration. The ACO-2200
includes dual external +12V PSUs, which provides power supply failure redundancy.
Features
The ACO-2200 includes the following key features:
• 6 channels in 1U rack height
• All BNC channels are signal agnostic
• All BNC channels are measured on both Primary and Backup inputs
• Ethernet (100-BaseT) interface remote control
•Nofans
• All Configuration settings performed through DashBoard
• Tight integration with SRG-2200

1. BACKUP - # - PRIMARY BNCs
Each triplet of BNCs relates to one changeover channel, comprising of a Primary input, a Backup input, and an
output.
›BACKUP — An input from the Backup SRG-2200 is connected here. The signal applied must be the same
format as the Primary.
›#— The switched output from either the Primary input or the Backup input appears on the center BNC of
each triplet. Which input appears here, and when, is determined by the configuration of the unit.
›PRIMARY — An input from the Primary SRG-2200 is connected here. The signal can be any one of the
supported types. The signal applied must be the same format as the Backup. If the channel is configured for
“No Measurement”, almost any signal may be connected (the user must take into account, and be aware of, the
limitations of the switching relay regarding voltage, current and signal bandwidth).
2. Ethernet 100-Base T Connection
This rear-panel connector is a standard RJ45 Ethernet connector. This is used for DashBoard communication.
After installation, it may be used to upload software updates.
3. DIP Switches
Use the DIP switches to force the IP Address and Subnet Mask for the ACO-2200 to known values.
4. PSU Connectors
The ACO-2200 is designed to operate from an external +12VDC power source. A safety earth stud is provided
for earth bonding the chassis if you so require.
You need to provide two power connections (for the two external +12V DC Power Bricks). For full power
security, these should be separate, independent and secure power grids. However, you still gain the security of
power supply failure redundancy if you use the same power grid for both connections.
5. PSU Presence LEDs
These LEDs indicate presence or absence of +12V.

ACO-2200 User Guide (v5.0) Physical Installation • 13
Physical Installation
This chapter provides instructions for installing the ACO-2200.

damage exists, document it, including photographs, to support any insurance claim.
2. Remove the instrument from the shipping carton.
3. Check that the ACO-2200 has not been damaged in transit. The exterior should not have any scratches or
impact marks. Prior to shipment the ACO-2200 is thoroughly inspected for mechanical defects.
4. Verify that the shipping carton contains the instrument, the standard accessories, and any optional accessories
that you ordered.
5. Perform the Functional Check Procedure as outlined in the section “Required Equipment” on page 17 after
installing the ACO-2200.
Save the shipping carton and packaging materials for ACO-2200 replacement re-packaging in case return
shipment becomes necessary.
Operating Environment Requirements
Verify that the location of your installation has the proper operating environment. The ACO-2200 operates correctly
in ambient temperatures from 0 °C to +40 °C and relative humidity from 20% to 80%.
For More Information on...
• environmental operating specifications, refer to the appendix “Technical Specifications” on page 33.
The ACO-2200 requires 2” (50mm) of side clearance for counter top use. Also, ensure sufficient rear clearance, e.g.
3” (75mm), so that cables are not compromised.
ESD Susceptibility — Static discharge can cause serious damage to sensitive semiconductor
devices. Avoid handling circuit boards in high static environments such as carpeted areas and when
synthetic fiber clothing is worn. Always exercise proper grounding precautions when working on circuit
boards and related equipment.

14 • Physical Installation ACO-2200 User Guide (v5.0)
The ACO-2200 does not have an internal fan to assist with ventilation or cooling. Therefore, when you install the
unit in an equipment bay, it is imperative that you ensure there is sufficient space all around the unit to allow the
airflow to vent away any excess heat generated by the unit.
Rack Mount Installation
You can install the ACO-2200 into an equipment rack. It is recommended to loom the cables so that they do not
introduce extra weight or twisting force on the front panel rack mountings or rear panel connectors. If installed in a
mobile application, the rack mount kit is essential.
This section describes how to install the ACO-2200 into the rack.
Installing the ACO-2200 into a Rack Unit
The ACO-2200 mounts in the rack cabinet by means of four screws through the front mounting flanges. This should
normally be sufficient to carry the load, including weight of cables. Refer to the ACO-2200 Quick Start Guide for
mounting details.
Installing the Rear Support Brackets
In some cases, (mobile trucks, etc.) it may be desirable to also support the rear of the ACO-2200. The rear support
bars can be attached to the ACO-2200 in six possible positions. (Figure 4.1)
Figure 4.1 Installing the Support Brackets
To install the support brackets
1. Choose the position that suits the cabinet depth and will give approximately a 0.5” projection beyond the
previously mounted bracket. The frame support bars can work with racks up to 26” deep.
2. Using four screws per bracket, as shown in Figure 4.1, attach both bars.
3. Mount the frame to the front rails of the rack cabinet using rack screws.
4. At the rear of the cabinet, slide the bracket slots over the rear of the support bars and secure to the cabinet rear
rails with rack screws.
Caution — The ACO-2200 could be damaged if it is powered on at temperatures or humidities outside
the specified ranges.
Warning — Do not use the support brackets to carry the ACO-2200. The brackets are not primarily
designed for this purpose, and property damage or personal injury may result.

Connecting Power
The ACO-2200 operates from an externally supplied +12VDC power source. A safety earth stud is provided for
earth bonding the chassis if you so require.
Your ACO-2200 includes two external +12VDC power supply blocks to provide you with full redundancy. For full
power security, these should be on separate, independent and secure power grids. However, you still gain the
security of power supply failure redundancy if you use the same power grid for both connections.
Connecting the Power Cable
Connect the power cable to the instrument first, and then connect it to the AC power source. Note that connecting a
live power cable causes the instrument to power on.
Replacing a Power Supply
Since DC power is provided from an external supply, if you need to replace a power supply, simply replace the
faulty external PSU.
Setting the Initial IP Address
The ACO-2200 is remotely controlled over an Ethernet link by a DashBoard client.
When using DashBoard to communicate with the ACO-2200, the ACO-2200 is always configured as a fixed IPv4
device using the DashBoard in conjunction with DIP switches SW1 and SW2 on the rear panel.
Configuring the DIP Switches
This section briefly summarizes the DIP Switch settings on the ACO-2200.
Figure 4.2 shows the DIP Switches in the OFF position.
Figure 4.2 DIP Switches on ACO-2200 Rear Panel

Although some steps are included which suggest cycling through menu options in order to check operation, this is
not mandatory - a simple check for presence or absence of a signal will suffice. Full details regarding the options
available in each of the menus are described in the chapter “DashBoard Menus” on page 27 of this manual. The
scenarios to be explored are:
1. Initial Power-Up
2. Initial Configuration
3. Normal Operation (no fault)
4. Loss and Restoration of a Primary Signal
5. Loss and Restoration of a Backup Signal
6. Loss and Restoration of Power
Only one channel will be considered here to avoid confusion. To check the whole unit, repeat this procedure for
each of the remaining channels, remembering to leave signals connected to previously checked channels.
Initial Power-Up
1. Ensure that the ACO-2200 is not powered on.
2. Connect the ACO-2200 as shown in Figure 5.1. Ensure that the ACO-2200 output is properly terminated at the
monitoring device.

The signal inputs are nominally different in order to easily verify which signal is switched to the output.
3. Apply power to the ACO-2200 by connecting it to the power source(s). The instrument runs its power-on
initialization process.
4. Check that no error messages appear on the LCD display.
5. Much of the functional check can be carried out immediately. However, some calibration settings are only
guaranteed once functional temperature has stabilized (which should occur after 20 minutes). It is good
practice to soak the instrument before proceeding.
6. User settings are made using DashBoard.
Recommendation
The ACO-2200 menu system contains an appreciable number of pre-programmed and user selectable settings. All
of these settings are programmed using the factory default procedure, and a select few are then adjusted during
testing and alignment. This is especially true of the Calibration menu, where settings relating to the fundamental
operation of each individual ACO-2200 are stored. If memory corruption occurs, some or all of the settings may
need to be re-instated.

To manually add the ACO-2200 to the Basic Tree View in DashBoard
1. From the DashBoard main toolbar, select File > New > TCP/IP DashBoard Connect or openGear Device.
The New TCP openGear Frame Connection dialog opens.
2. Type the IP address of the ACO-2200 in the IP Address field.
3. Type a unique name for the ACO-2200 in the Display Name field. This name makes the ACO-2200 easily
identifiable in the Tree View.
4. Click Finish.
5. Ensure that the ACO-2200 is displayed in the Tree View located on the left-side of the DashBoard window.
Consult the DashBoard User Manual should the Tree View not display the ACO-2200.
To access the ACO-2200 interfaces in DashBoard
1. From the Tree View, expand the node for the ACO-2200 you wish to configure.
2. Double-click a node to display its interface in the right-side of the DashBoard window.
In the example below, the Slot 0: ACO-2200 interface is displayed in the window.

20 • Functional Check Procedures ACO-2200 User Guide (v5.0)
Initial Configuration
The ACO-2200 should arrive configured to a “factory default” condition, where all channels have:
•Type set to Color Black
•Operational Mode set to Automatic
•Output set to Primary
To ensure that you have a suitable channel configuration for the purposes of this Functional Check, you should
perform the following procedures.
The procedures in this section assume that you have launched the DashBoard client and the ACO-2200 is displayed
in the Tree View.
To select the number of active channels
1. Double-click the Slot 1: Channel Setup node.
The Channel Setup interface displays in the DashBoard window.
2. Select the Configuration tab.
