1.2 Manual

Conventions To help you get the most out of this manual and our products, please note that

we use the following conventions:



Tips are designed to highlight quick ways to get the job done or to reveal

good ideas you might not discover on your own.

NOTE: Notes alert you to important information.

CAUTION! Caution advises you of precautions to take to avoid injury, data loss,

and damage to your boards or a system crash.

Text formatted in bold typeface generally represents text that should be entered

verbatim. For instance, it can represent a command, as in the following

example: “You can instruct users how to run setup using a command such as

setup.exe.”

Bold typeface will also represent field or button names, as in “Click Scan

Network.”

Text formatted in fixed typeface generally represents source code or other text

that should be entered verbatim into the source code, initialization, or other file.

Before you begin:



Before plugging any I/O connector into the Cube or RACK chassis,

be sure to remove power from all field wiring. Failure to do so may

cause severe damage to the equipment.

No HOT SWAP

Always turn POWER OFF before performing maintenance on a UEI system.

Failure to observe this warning may result in damage to the equipment and

possible injury to personnel.

Usage of Terms

Throughout this manual, the term “Cube” refers to either a PowerDNA Cube

product or to a PowerDNR RACKtanglerack mounted system, whichever is

applicable. The term DNR is a specific reference to the RACKtangle, DNA to the

PowerDNA I/O Cube, and DNx to refer to both.

1.3 MUX-414 /

MUX-418

Board

Overview

The DNx-MUX-414 boards provide 14 independent 1 x 3 switches for use with

UEI Cube and RACK systems.

The DNA-MUX-414, DNR-MUX-414, and DNF-MUX-414 board versions are

compatible with the UEI Cube, RACKtangle, and FLATRACK respectively. All

board versions are functionally identical except for the mounting hardware. The

DNA version is designed to stack in a Cube chassis. The DNR/F versions are

designed to plug into the backplane of a RACK chassis.

The DNR-MUX-418 boards provide 18 independent 1 x 3 switches for use with

UEI RACKtangle and HalfRACK systems.

MUX-414 / MUX-418 boards are designed for use in a wide variety of switching

and digital control applications.

1.3.1 Multiplexing

Modes Each channel provides a “common” terminal connected to three independent

SPST (Form A) contacts. In a typical SIL application, this allows each flight

computer signal to be connected to the actual trainer, a simulated device, a third

test or error signal, or left open to simulate a broken wire or other open circuit

condition.

1.3.2 Switch

Conditions Each channel is capable of switching voltages up to ±48 VDC, AC waveforms

with peaks less than ±48 VDC or sinusoidal signals up to 34 Vrms.

Each channel is rated for continuous operation at 1 A DC or AC rms (at -40 to

85°C) with a switch resistance of less than 0.2 Ω(typical, not including external

cables). All relays default to “open” on power up/reset.

Switching rates up to 250 Hz are supported, and all channels default to break-

before-make relay operation.

1.3.3 Synchro-

nization Input

and Output

Pins

MUX-414 / MUX-418 boards can synchronize relay switching via the sync in pin

and sync out pins.

The sync out pin can be configured to change state when programming a relay

state change, and the sync in pin can be configured to delay the switching of

relays until the sync in pulses. Wiring the sync out pin of the final board

configured with the sync in pins of multiple MUX-414 / MUX-418 boards allows

hardware synchronization of relay switching on all outputs.

1.3.4 Diagnostic

Capabilities Users have the capability of reading onboard 2.5 V and 3.3 V supply levels, as

well as onboard temperatures. Users can also read back the current state of

each relay.

1.3.5 Isolation &

Over-voltage

Protection

Each board provides 350 VDC isolation between channels, as well as between

the board, chassis and other installed I/O boards.

1.3.6 Support

Accessories All DNx-MUX-414 connections are made through a 62-pin D connector. Users

may also connect the boards to our DNA-STP-62 screw terminal panel via the

DNA-CBL-62 cables. The cables are fully shielded and are available in 1, 3, 6,

10 and 20 foot lengths.

All DNx-MUX-418 connections are made through a 78-pin D connector. Users

may connect the boards to our DNA-STP-78 screw terminal panel via the 

DNA-CBL-78 cables. The cables are fully shielded and are available in 

3 and 10 foot lengths.
