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.

1.7.1 Input Circuitry Each channel provides a common (COM) terminal connected to three
independent SPST “A”/”B”/”C” (Form A) contacts. Refer to Figure 1-3 below for
a simplified block diagram of channel muxing.
Figure 1-3. Single Channel Block Diagram for MUX-414 / MUX-418
1.7.2 Controlling
Multiplexers Channel relays are opened or closed based on a single write, written as a port.
This means that each channel can have “A”, “B”, “C” or “none” closed
independently, but when you write the configuration state, all 14 / 18 channels
are written at once as a group.
By default, when users write new relay states, all closed relays open before new
relay states are closed. This break-before-make functionality is user-
configurable. Users can disable this feature, as well as program a delay in
microseconds for how long the contacts will be open before new connections are
made.
1.7.3 Synchro-
nization I/O Users have access to synchronization functionality via a sync in pin on the DB
connector and sync out functionality via a sync out pin on the DB connector or
via internal chassis bus lines.
The sync out functionality can be enabled to change state when programming a
relay state change. The pulse width and level of the pulse is user configurable.
The sync in functionality can be enabled, which delays relay state changes until
a pulse is received on the sync in pin. Triggering on a level or edge change, as
well as the polarity (high/rising or low/falling) is user configurable.

Chapter 2 Programming with the High-Level API
This chapter provides the following information about using the UeiDaq
Framework High-Level API to control the MUX-414 / MUX-418:
•Creating a Session (Section 2.1)
•Configuring Mux Port (Section 2.2)
•Configuring the Timing (Section 2.3)
•Configuring Sync Input / Sync Output (Section 2.4)
•Writing Data (Section 2.5)
•Monitoring Supply Voltage, Temperature & Status (Section 2.6)
•Monitoring Relay States & Status (Section 2.7)
•Cleaning-up the Session (Section 2.8)
UeiDaq Framework is object oriented and its objects can be manipulated in the
same manner from different development environments, such as Visual C++,
Visual Basic, or LabVIEW.
The following section focuses on the C++ API, but the concept is the same no
matter what programming language you use.
Please refer to the “UeiDaq Framework User Manual” for more information on
use of other programming languages.
2.1 Creating a
Session The Session object controls all operations on your PowerDNx device. The first
task when programming using the high-level Framework is to create a session
object:
2.2 Configuring
Mux Port You use a Mux session to configure MUX-414 / MUX-418 channels. All channels
are configured as one port (mux0).
The MUX-414 / MUX-418 provides break-before-make functionality, which
defaults to opening all relays (A, B, and C) for a channel when opening or
closing any one relay (A, B, or C). You can disable this break-before-make
default functionality if you wish when creating the session.
The following call configures the mux port of a DNx-MUX-414 / MUX-418 set as
device 1 with break-before-make functionality enabled.
CreateMuxPort configures the following parameters:
• breakBeforeMake: true to enable break-before-make, false otherwise
(boolean).
// create a session object
CUeiSession muxSession;
// Configure session to write to port 0 on device 1
muxSession.CreateMuxPort("pdna://192.168.100.2/Dev1/mux0", true);

2.2.1 Configuring
Break-before-
make or Port
On Delay
Users can configure the delay that relays will stay open before closing (break-
before-make delay), whether or not break-before-make functionality is enabled,
and the delay before a new write will be accepted (port on delay).
By default, break-before-make circuitry is enabled, and the break delay is set to
250 µS. The default port on delay is 100 µS.
To enable/disable break-before-make and/or program delays, you first get a
pointer to the mux port object of the MUX-414 / MUX-418 board:
You can enable or disable break-before-make when you first create the channel
(see Section 2.2 above) or by using the EnableBreakBeforeMake method.
The following example shows you how to turn break-before-make off using the
EnableBreakBeforeMake method:
You can change the amount of time the A, B, and C relays for a channel open
before they close with the SetOffDelay method.
The following example sets the off delay to 350 µS:
You can change the amount of time before a new write command will be
accepted with the SetOnDelay method.
The following example sets the on delay to 150 µS:
2.3 Configuring
the Timing You can configure the MUX-414 / MUX-418 to run in simple mode (point by
point).
In simple mode, the delay between samples is determined by software on the
host computer.
The following sample shows how to configure the simple mode. Please refer to
the UeiDaq Framework User Manual to learn how to use other timing modes.
CUeiMuxPort* pChan =
dynamic_cast<CUeiMuxPort *>(muxSession.GetChannel(0));
pChan->EnableBreakBeforeMake(false);
pChan->SetOffDelay(350);
pChan->SetOnDelay(150);
// configure timing for point-by-point (simple mode)
muxSession.ConfigureTimingForSimpleIO();

2.4 Configuring
Sync Input /
Sync Output
Users can optionally configure the MUX-414 / MUX-418 to synchronize relay
switching to use an external hardware trigger via the sync in pins. Alternatively,
you can configure sync out pins to pulse on a relay write.
As an example, you can use the sync out pin on one MUX-414 / MUX-418 to
synchronize other MUX-414 / MUX-418 boards via their sync in pins.
To use this option, connect the sync out pin of the one board to the sync in pins
of the others (and connect sync gnd of all boards).
In your application, program multiple MUX-414 / MUX-418 boards to turn
channel relays on or off as needed, but configure the sync in flag to delay the
actual hardware switching until those boards receive a synchronization pulse on
their sync in pins. Then configure the MUX-414 / MUX-418 board that is
controlling sync out to pulse its MUX-414 / MUX-418 sync output pin when its
relay write is programmed.
2.4.1 Configure
Sync Out To program this, first get a pointer to the mux port object of the 
MUX-414 / MUX-418 board that you wish to configure the sync out pin for:
Configure the sync output mode with the SetSyncOutputMode API. 
The following configures the sync out pin to pulse low when the relays are ready
(otherwise it is high).:
SetSyncOutputMode accepts the following options for configuration:
CUeiMuxPort* pChanOut =
dynamic_cast<CUeiMuxPort *>(muxSessionOut.GetChannel(0));
pChanOut->SetSyncOutputMode(UeiMuxSyncOutputRelaysReadyPulse1);
Option Name Description
UeiMuxSyncOutputLogic0 drive constant logic '0'
UeiMuxSyncOutputLogic1 drive constant logic '1'
UeiMuxSyncOutputSyncLine0 through
UeiMuxSyncOutputSyncLine3 driven by internal SYNC BUS[0] through [3]
UeiMuxSyncOutputRelaysReadyPulse0 pulse logic ‘1’ on "relays ready" for a pulse width duration
of programmed with SetSyncOutputPulseWidth 
(100 µs default)
UeiMuxSyncOutputRelaysReadyPulse1 pulse logic ‘0’ on "relays ready" for a pulse width duration
of programmed with SetSyncOutputPulseWidth 
(100 µs default)
UeiMuxSyncOutputRelaysReadyLogic0 drive logic ‘0’ while "relays ready" (UEI internal test mode)
UeiMuxSyncOutputRelaysReadyLogic1 drive logic ‘1’ while "relays ready" (UEI internal test mode)

You configure the sync out pulse width with the SetSyncOutputPulseWidth
method. Note that the pulse width is only configurable when using the following
sync modes:
•UeiMuxSyncOutputRelaysReadyPulse0
•UeiMuxSyncOutputRelaysReadyPulse1
In this example, we configure the sync out pin to pulse low for 1 ms when the
relays are ready (otherwise it is high):
SetSyncOutputPulseWidth accepts 1 µS, 10 µS, 100 µS, and 1000 µS
options as the pulse width parameter.
2.4.2 Configure
Sync In To configure sync in, get the pointer(s) to the mux port object(s) of the 
MUX-414 / MUX-418 board(s) that you wish to configure the sync in pin(s) for.
To program this, first get a pointer to the mux port object of the 
MUX-414 / MUX-418 board that you wish to configure the sync in pin for:
Enable sync in:
Configure the sync in circuitry to trigger the relay writes on a rising edge:
Accepted values for SetSyncInputEdgePolarity are:
•UeiDigitalEdgeRising: Detect rising edge
•UeiDigitalEdgeFalling: Detect falling edge
pChanOut->SetSyncOutputPulseWidth(1000);
CUeiMuxPort* pChan =
dynamic_cast<CUeiMuxPort *>(muxSession.GetChannel(0));
pChan->EnableSyncInput(true);
pChan->SetSyncInputEdgePolarity(UeiDigitalEdgeRising);
pChan->EnableSyncInputEdgeMode(true);

2.5 Writing Data Writing data is done using a MuxWriter object.
The following sample shows how to create a writer object and write multiplexer
switches:
You program the multiplexer channels using the WriteMux method, which gets
passed how many channels you wish to program, which channels, and what
states.
You can program one of 4 mux states for each MUX-414 / MUX-418 channel:
•0: Open A, B, and C relays
•1: Close the A relay, open B and C
•2: Close the B relay, open A and C
•3: Close the C relay, open A and B
The following example of writes 5 channels: 0, 2, 5, 11, and 12, which are
reprogrammed with the following changes:
•channel 0: close relay A (1)
•channel 2: close relay B (2)
•channel 5: close relay C (3)
•channel 11: open all relays (0)
•channel 12 close relay C (3)
// create a writer and link it to the session’s stream
CUeiMuxWriter muxWriter(muxSession.GetDataStream());
// declare arrays to hold channels and states (up to 14 channels)
int channels[14];
int relays[14]
// set up list of channels as described in example:
channels[0] = 0;
channels[1] = 2;
channels[2] = 5;
channels[3] = 11;
channels[4] = 12;
// set up list of relay states as described in example:
relays[0] = 1;
relays[1] = 2;
relays[2] = 3;
relays[3] = 0;
relays[4] = 3;
// write the 5 channels
writer.WriteMux(5, channels, relays);

2.6 Monitoring
Supply
Voltage,
Temperature
& Status
The MUX-414 / MUX-418 provides the diagnostic capability of monitoring
onboard supply voltages and temperature using an onboard ADC. Additionally,
you can also retrieve status.
To monitor diagnostic data, use the ReadADC method.
You can read up to 5 diagnostic channels:
•ADC channel 0: <Reserved>
•ADC channel 1: The 3.3 V supply in volts
•ADC channel 2: The 2.5 V supply in volts
•ADC channel 3: The temperature in degrees C
•ADC channel 4: The status (uint32, see description in Section 2.7)
The following code shows how to read the voltage and temperature:
NOTE: You can also retrieve status data with the ReadStatus method (see
Section 2.7).
// read all 5 values
double adcBuffer[5];
muxWriter.ReadADC(5, adcBuffer, NULL);
// print supplies and temp
for(int j = 1; j<4; j++)
{
std::cout << " adc" << j << "= " << adcBuffer[j];
}
std::cout << std::endl;

2.7 Monitoring
Relay States
& Status
You can monitor current relay states and status data with the ReadStatus
method:
ReadStatus(uInt32 *relayA, uInt32 *relayB,
uInt32 *relayC, uInt32 *status)
where
•relayA: bitwise representation of relay A states (1 is closed, 0 open)
•relayB: bitwise representation of relay B states
•relayC: bitwise representation of relay C states
•status: bitwise representation of board status
Status is returned as:
•Bit 17: ‘1’ means data is ready from ADC
•Bit 16: ‘1’ means overrun (write while busy)
•Bit 3: ‘1’ means state machine is busy
•Bit 2: ‘1’ means output state machine is waiting for the 
external SYNC/ready
•Bit 1: ‘1’ means relays are settled
•Bit 0: reports the logic state of the sync in pin
•all other bits are <Reserved>
The following code shows how to read the relay states and status:
2.8 Cleaning-up
the Session The session object will clean itself up when it goes out of scope or when it is
destroyed. To reuse the object with a different set of channels or parameters,
you can manually clean up the session as follows:
// read all current relay state and status
uInt32 stRelayA, stRelayB, stRelayC, status;
muxWriter.ReadStatus(&stRelayA, &stRelayB, &stRelayC, &status);
// print results
std::cout << std::hex << " relayA=" << stRelayA <<
" relayB=" << stRelayB <<
" relayC=" << stRelayC <<
" status=" << status << std::dec << std::endl << std::endl;
// clean up the session
muxSession.CleanUp();
