This guide describes how to use the National Instruments LFH200 cable to connect the
NI PXI-2569/2570/2571/2575 or SCXI-1169/1175 switch module to your system.

The LFH200 cable is available in three configurations:

• SH200LFH-4xDB50F-C—Recommended for use with the PXI-2569/2570/2571 or
SCXI-1169.

• SH200LFH-4xDB50F-S—Recommended for use with the PXI-2575 or SCXI-1175.

• SH200LFH-BARE WIRE—Recommended for termination other than 50-pin female
D-SUB.

Caution The LFH200 cable has a maximum voltage rating of 60 VDC. When using

the LFH200 cable with switch modules, do not exceed 60 VDC.

Conventions

The following conventions are used in this guide:

» The » symbol leads you through nested menu items and dialog box

options to a final action. The sequence Options»Settings»General
directs you to pull down the Options menu, select the Settings item,
and select General from the last dialog box.

This icon denotes a note, which alerts you to important information.

This icon denotes a caution, which advises you of precautions to take
to avoid injury, data loss, or a system crash.

bold Bold text denotes items that you must select or click in the software,

such as menu items and dialog box options. Bold text also denotes
parameter names.

italic Italic text denotes variables, emphasis, a cross-reference, or an

introduction to a key concept. Italic text also denotes text that is a
placeholder for a word or value that you must supply.

monospace Text in this font denotes text or characters that you should enter from

the keyboard, sections of code, programming examples, and syntax
examples. This font is also used for the proper names of disk drives,
paths, directories, programs, subprograms, subroutines, device names,
functions, operations, variables, filenames, and extensions.

Getting Started

The following items are necessary for connecting the LFH200 cable:

❑ LFH200 cable

❑ NI PXI-2569/2570/2571/2575 or SCXI-1169/1175 switch module and documentation

Connecting the LFH200 Cable

Complete the following steps to connect the LFH200 cable to your switch module and
application. Refer to Figures 1 and 2 for illustrations of the LFH200 cable.

1. Connect the LFH200 connector to the connector on the switch module.

2. Tighten the thumbscrews.

3. Complete either of the following steps, and refer to Tables 1 through 16 to determine how
to connect your signals.

• Connect the D-SUB connectors to your application.

• Connect the unterminated wires to your application.

The cable in this kit connects an LFH200 connector to four, 50-pin female D-SUB connectors
marked P1–P4, or eight bundles, leg J0–J7, of unterminated, tinned, and stripped wires. The
LFH200 connector provides connection to the switch module. The 50-pin female D-SUB
connectors and unterminated wires provide connection to your application. Figures 3 and 4
show the pinouts for these connectors.

The LFH200 cable is available in three configurations:

• SH200LFH-4xDB50F-C

• SH200LFH-4xDB50F-S

• SH200LFH-BARE WIRE

The following sections describe each of the LFH200 cable configurations.

SH200LFH-4xDB50F-C Cable

The SH200LFH-4xDB50F-C cable is recommended for connecting the PXI-2569/2570/2571 or
SCXI-1169 to your system. One end of the cable terminates with an LFH200 connector which
connects to the switch module. The other end of the cable terminates with four 50-pin female
D-SUB connectors.

When using the SH200LFH-4xDB50F-C cable with the PXI-2569 or SCXI-1169, each Channel
and its corresponding Common form a twisted pair. For example, CH0 is paired with COM0,
and CH1 is paired with COM1. Figure 5 illustrates how this pairing relates to the pins on the
PXI-2569 or SCXI-1169.

Figure 5. Twisted Pair Groupings for the PXI-2569 or SCXI-1169

When using the SH200LFH-4xDB50F-C cable with the PXI-2570, each Channel and its
corresponding NO (Normally Open) connection form a twisted pair. The NC (Normally Closed)
connection is twisted with NO CONNECT wires. For example, COM0 is twisted with NO0, and
NC0 is twisted with a NO CONNECT wire. Figure 6 illustrates how this pairing relates to the
pins on the PXI-2570.

When using the SH200LFH-4xDB50F-C cable with the PXI-2571 the twisted pairs vary
depending on the channel. For the first 50 Channels, each COM and its corresponding NO
connection form a twisted pair. However, for the remaining 16 channels, the three components
(NC, COM, and NO) are each twisted with a NC component from the first 50 Channels. For
example, COM0 is twisted with NO0, and NC0 is twisted with NC50. COM1 is twisted with
NO1, and NC1 is twisted with COM50. COM2 is twisted with NO2, and NC2 is twisted with
NO50. Figure 7 illustrates how this pairing relates to the pins on the PXI-2571.

Refer to the NI Switches Help for a complete listing of channel names and pinouts.

The SH200LFH-4xDB50F-S cable is recommended for connecting the PXI-2575 or SCXI-1175
to your system. One end of the cable terminates with an LFH200 connector. The other end of the
cable terminates with four 50-pin female D-SUB connectors.

When using the SH200LFH-4xDB50F-S cable with the PXI-2575 or SCXI-1175, the positive
and negative leads of a channel form a twisted pair. For example, CH36+ is paired with CH36–,
and CH71+ is paired with CH71–. Figure 8 illustrates how this pairing relates to the pins on the
PXI-2575 or SCXI-1175 modules. Refer to the NI Switches Help for a complete listing of
channel names and pinouts.

SH200LFH-BARE WIRE Cable

The SH200LFH-BARE WIRE cable is recommended for connecting the switch module to your
system if termination other than 50-pin female D-SUB is required. One end of the cable
terminates with an LFH200 connector. The other end of the cable has eight bundles of
unterminated, tinned, and stripped wires.

The following tables list the pin assignments for the SH200LFH-BARE WIRE cable.

Note The first color listed in the Bare Wire Color column of Tables 9 through 16 is

the primary color of the wire. The second color listed is the stripe color.

Note Each of the eight bundles consists of 13 twisted pairs of wires. Only 25 of the

wires are used. Therefore, the 26th blue/red wire remains unused and unmentioned in
Tables 9 through 16.
