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.

The DDA-4010 is also configurable for Automatic Changeover from one input to the other on loss of input signal
allowing for an input Main/Standby scenario.
Due to the nature of ASI signals being phase sensitive, signal inversion is also possible for situations where an
inverted ASI signal needs to be corrected.

CONFIGURATION
The DDA-4010 may be configured as a Dual 1 In, 4 Out or a Single 1 In, Out distribution amplifier either locally via
on board DIP switch settings, or remotely via SNMP.
To configure DDA-4010 via SNMP, DIP switch Sw2-7 must be set to ON.
DDA-4010 DIP Switch Settings:

7
.
NOTE: 6 Due to the nature of ASI signals being phase sensitive, signal inversion is possible with this
switch for situations where an inverted ASI signal needs to be corrected.
7 When using TRAPS via SNMP, depending on how system is set up, in order to avoid double
reporting of alarms via the DDA-4010 card itself and the CDM card (SNMP Agent) of the
frame, major and minor SNMP alarms that are reported to the CDM card of the frame can be
disabled.
Not applicable to Dual mode.

NOTE: 8 Alarm O/P non-active with link not plugged into either 1-2 or 2-3 (permanently open circuited).
Single 1 In, 8 Out Quic Set-up Guide:
ChAx8 - Input A to all 8 Outputs (4 x Output A and 4 x Output B) Recloc ing DA:
Sw1-5 = OFF (Single 1 In, Out DA mode).
Sw2-5 = OFF (Input A primary input).
Note that it is also possible to set Input B to all Outputs, if desired.
ChBx8 - Input B to all 8 Outputs (4 x Output A and 4 x Output B):
Sw1-5 = OFF (Single 1 In, Out DA mode).
Sw2-5 = ON (Input B primary input).
Data Rate:
For automatic detection of signal type so that DDA-4010 will pass 3G-SDI, HD-SDI and SD-SDI/ASI
automatically:
Sw1-1 = OFF.
Sw1-2 = OFF.
For 3G-SDI only, HD-SDI only or SD-SDI/ASI only, see Sw1-1 and SW1-2 settings on page .
Note that Sw2-1 and Sw2-2 have no effect when being run in the Single 1 In, Out mode.
Recloc ing DA Mode:
Sw1-3 = OFF (Input reclocked. DA behaves as a reclocking DA).
Sw2-3 = Not Applicable.
Non-Recloc ing DA Mode:
Sw1-3 = ON (Input non-reclocked. DA behaves as a non-reclocking DA).
Sw2-3 = Not Applicable.
Reduced equalisation in a noisy environment:
Sw1-4 = ON (Input A cable equalisation reduced).
Sw2-4 = ON (Input B cable equalisation reduced. Relevant only if Automatic Changeover
enabled).
Automatic Changeover Mode:
On loss of primary input, secondary input will switch to all outputs. See Operation section for complete
description.
Sw1-7 = OFF (Auto Changeover disabled).
Sw1-7 = ON (Auto Changeover enabled).

Dual 1 In, 4 Out Quic Set-up Guide:
Note that in Dual 1 In, 4 Out mode, each half of the DDA-4010 behaves as an independent DA, which means that
each input can be set with different (or the same) data rate and Reclock/Non-Reclock mode settings.
Input A to 4 x Output A, and Input B to 4 x Output B:
Sw1-5 = ON (Dual 1 In, 4 Out mode).
Sw2-5 = Not Applicable.
Recloc ing Mode:
Sw1-3 = OFF (Input A reclocked. A input behaves as a reclocking DA).
Sw2-3 = OFF (Input B reclocked. B input behaves as a reclocking DA).
Non-Recloc ing Mode:
Sw1-3 = ON (Input A non-reclocked. A input behaves as a non-reclocking DA).
Sw2-3 = ON (Input B non-reclocked. B input behaves as a non-reclocking DA).
Reduced equalisation in a noisy environment:
Sw1-4 = ON (Input A cable equalisation reduced).
Sw2-4 = ON (Input B cable equalisation reduced).
Automatic Changeover Mode:
On loss of one input, other input will switch to all outputs. See Operation section for complete description.
Sw1-7 = OFF (Auto Changeover disabled).
Sw1-7 = ON (Auto Changeover enabled).

INSTALLATION
Pre-installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling precautions
should be observed.
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.
Signal Inputs & Outputs:
For use with supplied standard rear assembly (ZDA-4010) or optional relay bypass rear assembly (ZDA-4010RL).
The DDA-4010 can be configured as a single 1 IN, OUT distribution amplifier, or as a dual 1 IN, 4 OUT distribution
amplifiers as described in the Configuration section of this handbook. If set up for a 1 IN, OUT distribution
amplifier, either input can be configured as the primary input. The other input is not used except when the
automatic changeover function is enabled, in which case this becomes the secondary input. See the Operation
section of this manual for a complete description.
Inputs, Outputs and front panel monitoring ports are 75 Ω BNC type for connection with high quality 75 Ω coaxial
cable. Inputs are self-terminating.
An optional relay bypass rear assembly (ZDA-4010RL) is available where the inputs are outputted to one of the
respective outputs (OUT 1A for Input A, and OUT 1B for Input B) on loss of power or removal of the card from the
rear assembly itself. The bypass relay is suitable for all specified signals up to 3G-SDI. Note however that the cable
equalisation at the 3G/HD-SDI rates and the return loss at the 3G-SDI rates are reduced through these relays. Note
also that if operating in the 1x mode, if anything is connected to the secondary input this too will be switched to
one of the outputs on loss of power or removal of card.
