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 software configurable to drive or
receive four differential 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.
NI 9469 Getting Started Guide | © National Instruments | 7
Page 8
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.

documentation for your specific software 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-
10 | ni.com | NI 9469 Getting Started Guide
Page 11
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,
T
rig 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 software 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.
16 | ni.com | NI 9469 Getting Started Guide
Page 17
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.
