CONFIGURATION
The DDA-4010 may be configured as a Dual 1 In, 4 Out or a Single 1 In, 8 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:
Input A signal type (rate set)
SW1-1

SW1-3
OFF Reclocking mode. DA behaves as a Reclocking DA.
ON Non-Reclocking mode (Reclocker bypassed). DA behaves as a Non-Reclocking DA.
SW1-4
OFF I/P A Normal cable equalisation.
ON I/P A Reduced cable equalisation to ~ 70m for shorter cable for use in a noisy environment.
SW1-5
OFF Single 1 In, 8 Out DA mode.
ON Dual 1 In, 4 Out DA mode (IN A → ‘A’ Outputs (OUT 1A, OUT 2A, OUT 3A & OUT 4A);
(IN B → ‘B’ Outputs (OUT 1B, OUT 2B, OUT 3B & OUT 4B).

ON I/P B primary I/P of single 1 in, 8 out DA (IN B → All 8 Outputs).
SW2-6
OFF Non-invert I/P B
(Default position)
.
ON Invert
6
I/P B.
SW2-7
OFF DIP Switch control. Settings as per DIP switch settings.
ON SNMP control. Settings as per SNMP settings.
SW2-8
OFF Enable major and minor SNMP alarms to the frame Agent (CDM card)
7
.
ON Disable major and minor SNMP alarms to the frame Agent (CDM card)

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.
