use of a tool.
Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits
for electromagnetic compatibility (EMC) stated in the product specifications. These
requirements and limits provide reasonable protection against harmful interference
when the product is operated in the intended operational electromagnetic
environment.
This product is intended for use in industrial locations. However, harmful
interference may occur in some installations, when the product is connected to a
peripheral device or test object, or if the product is used in residential or
commercial areas. To minimize interference with radio and television reception and
prevent unacceptable performance degradation, install and use this product in strict
accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved
by National Instruments could void your authority to operate it under your local
regulatory rules.
Caution To ensure the specified EMC performance, operate this product
only with shielded cables and accessories.
Special Conditions for Marine Applications
Some products are approved for marine (shipboard) applications. To verify marine
approval certification for a product, visit ni.com/product-certifications, search by
model number, and click the appropriate link.
Notice In order to meet the EMC requirements for marine applications,
install the product in a shielded enclosure with shielded and/or filtered
power and input/output ports. In addition, take precautions when

designing, selecting, and installing measurement probes and cables to
ensure that the desired EMC performance is attained.
NI 9469 Overview
The NI-9469 is a synchronization module for C Series platforms. It has a configurable
multi-port interface that enables distribution of triggers and clocks from a host
chassis, and an onboard DDS and PLL for clock generation and synchronization
capabilities.
Connecting the NI 9469
The NI-9469 has three RJ45 connectors on the front panel labeled Port 0, 1, and 2.
These connectors use standard straight through CAT 5e Ethernet cabling to provide
connection to other NI-9469 modules only . Each port is soware configurable to
drive or receive four dierential signals through the cable, which are referred to as
Line 0 to 3. Each port can carry either four triggers, or three triggers and one clock,
in which Line 3 is dedicated to carry the clock.
Routing the NI 9469
The NI-9469 features a configurable crosspoint switch. You can control the routing
of signals and the onboard clock generator between each front port and the trigger
lines in the backplane. However, the crosspoint switch is not a full routing matrix.
You can connect only the same Line or Trig number. For example, Line 0 to Trig 0,
but not Line 0 to Trig 2. However, you can route clock signals on only Line 3 or Trig 3.
The following figure details the crosspoint switch's routing capabilities.
Note You can set only eight of the 12 total port lines as outputs due to
power constraints.

Note The preceding figure details hardware routing capability only.
Soware imposed limitations may prevent certain routing or input/output
functions from being realized. For more information, refer to the
documentation for your specific soware platform.
NI 9469 Application
In a basic application, a single NI-9469 module is inserted into each host C Series
chassis. One module is set as master, the remainder as slaves, and all modules are
connected with a tree topology. Figure 2 shows a tree topology example. More
advanced and customizable options create a flexible topological network of NI-9469
modules. Refer to the Topologies section for examples of various topological
networks.
Based on user needs, you may desire certain topologies over others due to
application or timing requirements. Because signals are physically propagated over
cabling, the module cannot compensate for inherent cable delays and skew. For
example, if all slave modules must receive triggers at the same time with minimal
skew and delay, a star topology with short length-matched cables is preferred. Refer
to Figure 3 for a star topology configuration example.
If maximum separation distance is required, connect the modules using a daisy
chain topology with maximum cable length per hop, as shown in Figure 4. Refer to
the Cable section for information about maximum cable length.

Activity LEDs
The NI-9469 has four front panel LEDs labeled Trig 0, Trig 1, Trig 2, and Trig 3/Clk.
The LEDs blink when activity is detected on the corresponding line to or from the
carrier.

Sleep Mode
This module supports a low-power sleep mode. Support for sleep mode at the
system level depends on the chassis the module is plugged into. Refer to the chassis
manual for information about support for sleep mode. If the chassis supports sleep
mode, refer to the soware help for information about enabling sleep mode. Visit
ni.com/info and enter cseriesdoc for information about C Series documentation.
Typically, when a system is in sleep mode, you cannot communicate with the
modules. In sleep mode, the system consumes minimal power and may dissipate
less heat than it does in normal mode. Refer to the Specifications section for more
information about power consumption and thermal dissipation.
Notice that when the NI 9469 is in sleep mode, the clock generation settings (if used)
must be reconfigured when the module exits sleep mode and power is restored.
