V.3 DXDPRO-10U APPLICATIONS AND INSTALLATION
C. DIGITAL UPGRADE NOTES
The DXDPRO-10U is suitable for upgrading analog transmitters to digital service. Special attention must be
given to every detail of the conversion to insure that the desired objective is met and that it is compliant with
FCC requirements. The equipment used to make a conversion is expensive and can be costly. The
following needs to be considered when making a conversion to digital from analog;
1. Replace the modulator with a good quality digital modulator with adaptive linear and non-linear
correction
2. Check the drive level required to achieve the desired output power level from the transmitter. A
driver may be required after the modulator
3. The output band pass filter will have to be replaced with a MASK FILTER. Consider using a Mask
Filter that is rated at 1.25 times the desired output power level.
4. Digital transmitters and mask filters need to be correctable by the modulator. This will require the
addition of dual directional couplers before and after the mask filter to provide correction signals.
5. IMPORTANT: Modification of FCC approved equipment requires special test and test equipment. A
qualified Broadcast engineer should be employed to do this work.
D. 48 VDC OPERATIONS
The DXDPRO-10U Modulator is designed to be used with an external 48 VDC supply similar to those found
at TELECOM SITES. If the Modulator is used with standard AC supplied power sources the DC backup
can be automatically switched with internal circuits. The battery charge level can be monitored on the front
panel or on the web page. The operating range is from 42 to 52 VDC.
E. GPS RECEIVER ACTIVATION
The DXDPRO has a built in GPS receiver. The input port is located as show below;

V.5 DXDPRO-10U ETHERNET WEB PAGE CONTROL AND MONITORING
B. ETHERNET WEB PAGE SETUP
General Introduction
The web service control interface allows monitoring of status as well as configuration of the operational
parameters of the device subject to the log-in status for the user (observer, operator or administrator). The user
interface (web browser display) applies a user friendly concept where the general navigation between individual
sub menus is based on a block oriented representation of the controlled device. The specific control for a certain
function is therefore easily accessed by ‗dragging‘ the functional block of interest into the configuration section of
the display.
The web service interface is equally useful for controlling the PT2000 Terrestrial Gateway product in a
configuration with a direct connection (Ethernet patch cable) between the PT2000 Terrestrial Gateway product
and the PC as well as in the typical operational environment where multiple products are accessible from the PC
across a shared network.
Document structure and scope
This instruction manual is divided into three main sections:
Electrical interface and IP address configuration;
Operation principle for the Web service interface; and,
Software update over Ethernet.
The present document describes the operation from a generic viewpoint and it does therefore not address in
detail functions or settings applicable to a specific member of the Terrestrial Gateway product family.
C. IP ADDRESS CONFIGURATI0N
IP address settings for the PT2000 Terrestrial Gateway product can be carried out in several different ways:
a) Hardware preset to default status
b) Configuration over Ethernet (the current address setting must be known and that the PC used for the
configuration must be configured with a compatible address)
1. IP Address Preset
IP address : 192.168.168.168
Network Mask: 255.255.0.0

D. WEB SERVICE OPERATION
The PT2000 Terrestrial Gateway product is fully controllable over ethernet by means of the web service function
(web browser control). The PT2000 web service is designed for use with Internet Explorer V7 and Mozilla
Firefox V2 so it is strongly recommended to use one of these two browser types for the operation. The PT2000
Terrestrail Gateway unit must be configured in advance for the same address space as the PC used for the control
and the PC must be connected to one of the TCP/IP mangement eithere directly or over a network.
Preparation Of The Web Browser
The status pages provided by the PT2000 web service are updated in the web server whenever the operational
status of the device changes. However, changes to operational status, occurrence of alarm messages, etc, may be
masked if the web browser is configured for use of locally cached web pages. To ensure that the web browser
always displays the latest status from the PT2000 web service and not displays outdated cached information it
must be configured specifically to check for newer versions of a web page on every visit to the page. For Microsoft
Internet Explorer 7 this is done as follows:
a) Select ‗Internet options‘ from the ‗Tools‘ menu.
b) Select ‗Browsing history‘ ‗Settings‘ from the ‗‘General‘ tab page.
c) Make sure ‗Every time I visit the page‘ is ticked.
1. Login To The Web Service
Connection to the web service function is established simply by entering in the Web browsers address field the IP
address assigned to the specific PT2000 Terrestrial Gateway unit. A login window will appear in order to
authenticate the user‘s access to the web service. Login can be made at three different levels:

2. Web Service Main Page
Connection to the web service function is established simply by entering in the Web browsers address field the
IP address of the PT2000 Terrestrial Gateway unit. As soon as the connection has been opened the primary
control and status page will appear. The page is divided into an upper section and a lower section.
The upper section provides a graphic representation of the block schematic of the device. The block schematic
provides general status information about the device and serves as navigation tool for accessing specific
status and configuration menus.
The lower section provides space for simultaneous display of three control and status panels for specific
functional areas of the unit. The control panels are easily adapted to the current activity by dragging-and-
dropping the required functional block from the upper section of the screen to the lower section of the screen
(See next page - Section D.- Web Service Operation –- Part 3 - Control Panel Configuration for details).
In case an alarm condition exists for one of the functional elements shown in the upper section of the screen,
the particular element will be shown in red color. Functional elements that are in the normal operational status
will be shown in green color. Functional blocks that are not used in the current configuration are shown in grey
color.

Control panel configuration
The control panel (lower section of the screen) is easily adapted to the current activity by dragging-and-
dropping the required functional block from the upper section of the screen to the lower section of the screen.
Control panels for three functional blocks can be open simultaneously in the lower section.
The ‗Functional Blocks‘ in the upper section of the screen can be subdivided into three types:
Main function block: a main function block holds the top level control and status parameters for a
specific function. These blocks are identified by the blue label ‗attached‘ above the block (white text on
blue background). In the below example screen print main functional blocks exist for the sub-functions
Reception, Input, Mode, Pre-Correction, Output and Reference.
Specific function block: a specific function block holds control and status functions for a specific
function within a ‗Main functional block‘. In the below example screen print it can for example be noted
that the Reception main block contains specific functional blocks for the tuner and the channel filter
functions. Likewise, it can be seen that the mode block contains specific functional blocks for the HP
Coder, LP Coder, OFDM and SFN functions.

SW/FW update
SW/FW update of the PT2000 Terrestrial Gateway product is carried out over the ethernet interface. The
update is based on a so called ‗tarball‘ file that contains the SW/FW images that define the specific product
version (for example a DVB-T/H modulator, an ATSC modulator or a MediaFLO modulator). The typical size of
the ‗tarball‘ is about 16Mb.
The update procedure is as follows:
1. Download the ‗tarball‘ file from the FTP site to a directory on your local network or to the PC that you
are using explicitly for managing the PT2000 Terrestrial Gateway unit or insert the CDROM that
contains the tarball into a CDROM drive on this PC.
2. Connect to the Web service interface of the PT2000 Terrestrial Gateway product as described in
Section D, Web Service Operation--1. Login to the Web Server, page 31.
3. In the lower left corner of the Web service graphical user interface you will find the [System] button.
Click this button to open the system menu.
4. In the system menu select the function [SW Upgrade]. See Section D, Web Service Operation—
Subsection 3- Web Service - Operation Principle - Access to System Parameters, on page 39, for
further details about access to the system menu.
5. In the Maintenance section of the System menu select Software Upgrade
6. Select [Browse] and navigate to the location of the downloaded ‗tarball‘ file
7. Select the file ‗tarball.tgz’ and click [Upload]
8. The loading of the new SW/FW should now start automatically. The progress can be monitored from
the Web service interface. A number of steps including uploading, unpacking and verifying and deleting
files will pass automatically (the processing time is several minutes).
9. When the loading of new SW/FW is completed the unit will automatically reboot. After the reboot the
new SW/FW version is active.
10. The active SW/FW version can be verified after the reboot via the [About] function in the [System]
menu.

V.6. DXDPRO-10U ADAPTIVE PRE-CORRECTOR WEB SERVICE OPERATION
A. INTRODUCTION
This section describes the web browser based operation of the Adaptive pre-corrector for the PT2000
Terrestrial Gateway unit. For an introduction to IP address configuration, log-in procedure and general
operation principle for the web service1 control interface for the DXDPRO product family please refer to the
separate publication DXDPRO Modulator and Repeater Products Web service Interface Instruction Manual
available from Pineapple Technology, Inc..
The web service control interface allows monitoring of status as well as configuration of the operational
parameters of the adaptive pre-corrector device subject to the log-in status for the user (observer, operator
or administrator). The user interface (web browser display) applies a user friendly concept where the general
navigation between individual sub menus is based on a block oriented representation of the controlled
device. The specific control for a certain function is therefore easily accessed by ‗dragging‘ the functional
block of interest into the configuration section of the display.
The web service interface is equally useful for controlling any of the PT2000 Terrestrial Gateway products in
a configuration with a direct connection (Ethernet patch cable) between the PT2000 Terrestrial Gateway unit
and the PC as well as in the typical operational environment where multiple products are accessible from the
PC across a shared network.
SECTION STRUCTURE AND SCOPE
This section is divided into three main chapters:
a. Electrical interface for the adaptive pre-corrector
b. Operation principle for adaptive pre-corrector
c. Application of the adaptive pre-corrector in combination with Echo Canceller option
.
B. ELECTRICAL INTERFACE
1. General information
The adaptive pre-corrector‘s electrical interface consists of two SMA type coaxial connectors:

2. Interface to the Transmitter
The non-linear sense input must be connected to a suitable coupler/tap-off at a point right after the power
amplifier before any band limiting filter. The linear sense input must be connected to a suitable
coupler/tap-off point after the channel filter. Notice further that the bandwidth between the RF output of
PT2160 and the input of the power amplifier must be at least 20MHz wide to ensure effective non-linear
pre-correction of the amplifiers non-linearity.

C. OPERATION OF ADAPTIVE PRE-CORRECTOR
1. Connection and Verification of Signal Levels
The RF output and the sense inputs of the PT2000 Terrestrial Gateway unit must be connected as described
in above in Sub-section 2 - Interface to the Transmitter. The graphical illustration of the two sense inputs in
the web service block schematic will appear in green color if the level is within the valid range for the
respective input. If the level is marginal relative to the required max/min limits the input will be shown in
yellow color. If the level is outside the valid range the input is shown in red color. For optimal result the
corrector should only be operated with input levels in the ‗green‘ state. Performance with ‗yellow‘ input state
is not guaranteed. The adaptive pre-corrector is not usable when the level is in the ‗red‘ state.

2. Preparation of Web Service Interface
To enable web service control of the non-linear and linear adaptive pre-corrector, proceed as follows:
a) Drag the linear pre-corrector block to the configuration panel
b) Drag the non linear pre-corrector block to the configuration panel
c) Drag the adaptive pre-corrector block to the configuration panel (this panel provides status info
only and it is therefore as such not strictly required for operation of the adaptive system)
d) Drag the three control blocks into the configuration panel one-by-one:
Depending on the current operational mode for the pre-corrector system the linear and non-linear blocks
may appear in grey or in green. When the pre-corrector function is disabled the respective block (linear
and/or non-linear) is shown in grey. When the pre-corrector function is enabled the respective block
(linear and/or non-linear) is shown in green color. When the active pre-corrector mode is ‗adaptive‘ a
green arrow will connect the adaptive function block and the respective pre-corrector block. When the
adaptive pre-corrector mode is ‗static‘ (manual correction mode) the connection between the adaptive
function block and the respective pre-corrector block is grayed out.

Linear Pre-Corrector Mode Selection
The linear pre-corrector system can operate in three different modes. The required mode is selected by
opening the operational mode ‗drop-down‘ list (I).
The available modes are:
Monitoring: No pre-correction is applied to the RF output (the corrector characteristic is
neutral). The amplitude ripple and the group delay performance is measured and displayed
provided that a valid feedback is applied to the RF sense input 2.
Static: The currently loaded manual linear pre-corrector characteristic is applied to the RF
output. The manual pre-corrector characteristics must be generated and uploaded by means of
the PC software package IMD Buster McTwo. The curve format used by the manual pre-
corrector system is incompatible with the curves used and generated by the adaptive system.
Adaptive: The current adaptive linear pre-corrector characteristic is applied and maintained
according to the adaptive pre-corrector mode selected (see below for details).

Adaptive Linear Pre-Corrector Mode Selection
The adaptive linear corrector can operate in four different modes. The required mode is selected by
opening the operational mode ‗drop-down‘ list (II).
The available modes are:
Idle: The current adaptive pre-corrector characteristic is applied to the RF output. The pre-
corrector algorithm is stopped. Changes in transmitter characteristic will not be tracked by the
pre-corrector.
Continuous: The instantaneous adaptive pre-corrector characteristic is applied to the RF
output. The pre-corrector algorithm runs continuously.
Run to target: The instantaneous adaptive pre-corrector characteristic is applied to the RF
output. The pre-corrector algorithm will run until the set threshold value is obtained for the

Auto run: The instantaneous adaptive pre-corrector characteristic is applied to the RF output.
The pre-corrector algorithm will run until the set threshold value is obtained for the upper
respectively the lower RE spectrum shoulder. The adaptive pre-corrector algorithm will be
automatically restarted in case the upper and/or lower shoulder performance subsequently
drops below the set threshold.
Adaptive Linear Pre-Corrector Threshold Settings
The threshold values for the adaptive pre-corrector system‘s ‗Run to target‘ and ‗Auto run’ modes are
accessed and set by expanding the ‗Auto-run and run-to-target threshold settings‘ control (III). Notice
that the respective parameter values must be ‗enabled‘ by ticking the associated enable field in order for
the parameter to have any effect on the pre-corrector algorithm.

Last turn-around time: Displays the recorded time consumption for the last completed iteration
(data collection/analysis/curve implementation). The iteration time may typically vary from less than
10 seconds up to about one minute depending on the signal characteristic and the type of adaptive
correction running. The shortest iteration time is noted when only the non-linear adaptive pre-
corrector is running. The iteration time is increased when the adaptive linear pre-corrector process
is running.
Linear clean run: Accumulated count of the number of times the adaptive system has discarded
the collected linear data set and initiated a new collection of data. Under normal conditions this
counter is ‗0‘.
Linear bad sense count: Accumulated count of the number of times the data collection from the
linear sense port has failed for reasons other than level out of range (typically due to application of
an invalid type of spectrum on the sense port). Under normal conditions this counter is ‗0‘.
Non-Linear clean run: Accumulated count of the number of times the adaptive system has
discarded the collected non-linear data set and initiated a new collection of data. Under normal
conditions this counter is ‗0‘.
Non-Linear bad sense count: Accumulated count of the number of times the data collection from
the non-linear sense port has failed for reasons other than level out of range (typically due to
application of an invalid type of spectrum on the sense port). Under normal conditions this counter

D. ECHO CANCELLING AND ADAPTIVE PRE-CORRCTION
NOTICE: THIS FEATURE IS NOT INCLUDED IN THE DXDPRO LINE PRODUCTS.
THIS IS AVAILABLE AND THE CUSTOMER SHOULD REQUEST A QUOTATION FOR
PRICE AND AVAILABILITY.
The adaptive pre-corrector option works very well in combination with the echo canceller option by ISO-
channel repeater mode with the DTXPRO-10U digital repeater unit from Pineapple Technology, Inc.
However, the echo canceller‘s ability to work effectively with high positive loop gains is dependent on already
completed linearization of the amplifier non-linearity by the adaptive pre-corrector system. Therefore, when
setting in operation a system that involves the adaptive pre-corrector as well as the echo canceller in an ISO-
channel scenario it is recommended to follow one of the following two methods:
Off-Line Linearization
The ISO-channel repeater should initially be put in operation in a configuration where feedback
between output and input is non-existent. This can be done either by feeding:
a) The input with the actual RF feed off-air while feeding the power output from the ISO-repeater
into a dummy load instead of feeding it to the transmitting antenna or
b) A locally generated RF feed into the unit from a test transmitter which is not affected by the
output of the ISO-channel repeater.
In this configuration the adaptive non-linear pre-corrector should be run until a shoulder performance of
about 40dB or better is obtained from the power amplifier. After this initial linearization of the power
amplifier the ISO-repeater can be put in operation with ‗live‘ input and output.
Gradual Loop Gain Ramp-Up
The ISO-channel repeater may alternatively be put in operation by starting at a low ‗max loop gain‘
setting for the echo canceller (for example 0dB or lower) and for each step allowing the adaptive non-
linear pre-corrector to maximize the power amplifier performance to a shoulder level of about 40dB or
better before increasing the permitted loop gain by a few dB.

E. APPENDIX-A CLIPPER OPERATION
1. GENERAL INFORMATION
The clipper function included with the Terrestrial Gateway product allows a controlled limitation of the
output signals peak-to-average-power-ratio (PAPR).
When the clipper is disabled the output from the Terrestrial Gateway product will exhibit a PAPR
equivalent to the inherent PAPR for the modulation format when the unit is configured/operated as a
modulator. When the unit is configured as repeater or transposer the PAPR of the processed signal may
be limited by headroom constraints in equipment prior to the repeater or transposer input. In the latter
scenario the PAPR measured on the RF output may therefore be lower than the inherent PAPR for the
modulation format in question even when the clipper is off.
Although the highest power peaks for multicarrier COFDM formats like DVB-T and MediaFLO reach a
level about 15dB over the signals average RMS power the high peaks have limited energy content. The
peaks are therefore not of immediate danger to the safe operation of a power amplifier following the
modulator output even in the normal case where the average power setting for the amplifier is not
backed off with the full PAPR relative to the peak power rating for the amplifier. The highest peaks are
simply clipped by the power amplifier. However, a performance improvement and an extension of
amplifier lifetime may be obtained if the peaks are limited to a point just below the amplifiers clip point by
the clipper function of the Terrestrial Gateway product. When the clipping is done by the Terrestrial
Gateway the following characteristics are obtained:
a) The potential short time effect on the amplifier characteristic after a power peak is eliminated; the
clipping in the Terrestrial Gateway is an instant process with no subsequent effect on the signal
processing characteristic.
b) The unavoidable noise that results from the clipping may, when the clipping takes place in the
DXDPRO modulator, be distributed as preferred by use of the ‗soft clipper‘ function (see below).
When the clipping occurs in the amplifier the noise resulting from the clipping will be distributed
evenly below, within and above the used channel. When using the clipper function of the Terrestrial
Gateway the noise may be displaced from the upper and lower sideband of the channel to minimize
disturbance of adjacent channels.
c) By clipping the signal in the Terrestrial Gateway product any possible degradation of amplifier life
time by repeated peak power stress is minimized.
2. OPERATION OF THE CLIPPER FUNCTION
Level Definition
The point of clipping relative to average power level for the signal processed can be set by dragging the
clipper block to the configuration panel. The Clipper level control can be set in the range from 12dB to
2dB. This setting refers to the baseband processing which is equivalent to a range from 15dB to 5dB for
the actual RF output (the addition to the signal of a single CW carrier, the local oscillator used in the up-
conversion process, corresponds to an increase of the PAPR by 3dB).

3. OPERATION OF THE CLIPPER FUNCTION
For practical reason the clipper function is considered ‗active‘ whenever the clip point is set to a value
lower than 12dB irrespective of the actual PAPR format for the modulation standard in use. When set to
the ‗active‘ state the clipper is shown in green color in the block schematic. When the clipper is inactive it
is shown in grey.
Clipper in the inactive ‘off’ state (12dB):
Clipper active (PAPR setting 8dB):

E. APPENDIX-A CLIPPER OPERATION
3. OPERATION OF THE CLIPPER FUNCTION
Identification of Optimal Clipper Setting
The optimal clipper setting can be identified by monitoring the output of the power amplifier using a
spectrum analyzer. The steps are as follows:
a) Ensure that the clipper initially is set to 12dB
b) Ensure that the clip filter is initially set to 0%.
c) Configure the spectrum analyzer for zero-span operation with the view focused on either the upper
or lower shoulder of the signal. A resolution of 0.1dB to 0.5dB per division is recommended.
Maintaining the original level in the form of a second trace on the analyzer (clear-write View) is
recommended for easy identification of change in the shoulder level.
d) Now, gradually increase the level of clipping applied by the Terrestrial Gateway product
(1211,51110,510……..etc). When an increase of the shoulder level observed on the
spectrum analyzer is just noticed it shows that the clipping applied by the Terrestrial Gateway is
now limiting the peaks to a point fractionally below the clip point of the amplifier itself. Although the
point will be individual from amplifier to amplifier and dependent on the actual average power level
and peak power rating of the amplifier the point is typically found around of a clipper setting
between 8 to 6 dB.
Selection of Clipper Softness (Clip Filter)
The clip filter setting may be varied according to preferences between 0% and 100%. The 100% setting
provides for maximum suppression of the clipper noise from the sidebands (lower and upper adjacent
channel) while the tradeoff is a reduction of the in-band MER performance.

VI. DTXPRO-10U INSTALLATION PROCEDURES
To ensure long and reliable trouble-free service from the DTXPRO-10U transmitter, the following
steps for installation are recommended:
1. MECHANICAL INSTALLATION: The DTXPRO-10U was designed to be installed in a building
protected from the weather. The building should have a hard-surface floor such as concrete with
a moisture barrier. This barrier could be pressure-treated wood sub flooring which could be
anchored to the concrete and to the transmitter to make the installation earthquake resistant.
Allow a minimum of three feet around the transmitter cabinet for service access.. Provisions for
air inlet and exhaust from the room must allow air flow with minimal obstruction. In the event
that the room temperature exceeds 35º Celsius (95º F), cooling air must be provided so that the
room temperature will not exceed 35 degrees Celsius under worse case conditions.
Notice: This equipment is HEAVY and must be handled by professional movers with proper
equipment. Any damage caused by the installers is not covered under warranty. Check to
ensure the installing crews have proper insurance coverage.
2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for
safety and operational reasons. The single point grounding technique can be effective to protect
multiple pieces of equipment installed inside an equipment rack cabinet. Treat the rack the
same as you would a building, a copper bus bar has been mounted inside the cabinet to act as
both an entrance panel and reference ground for all conductors entering and leaving the rack. It
is recommended the customer install an AC surge protector at this point in shunt to ground, and
install a series impedance between the panel and the equipment. The chassis of each piece of
equipment has been bonded to this buss bar with a single copper braid or strap. Redundant
ground connections by means of the AC cable and the shields of audio cables should be
avoided when possible. Finally, connect the rack‘s access panel to the building reference
ground using a heavy gauge wire such as #2 AWG stranded copper or solid copper buss one
(1) inch wide by 1/8 inch thick for connections. The bonding between the transmitter and the
ground rods must be good quality and protected from corrosion. The ground wires should run
over the floor and be connected to the ground rods located outside the building. The wire should
not go thru the concrete floor but over and around it.
3. AC WIRING: AC voltage for the transmitter is normally 110 VAC. Connections to the AC Main
should be made as follows:
--- RED and BLACK wires are connected to the 110 VAC.
--- WHITE wire is connected to NEUTRAL.
---GREEN wire is connected to SAFETY GROUND.
NOTICE: All wiring of this type must be done by a QUALIFIED ELECTRICIAN and must
conform to LOCAL and NATIONAL wiring CODES.
Consult with your electrician to ensure that the proper breaker size is selected for the main
circuit.

4. ANTENNA CONNECTION: The transmitter is equipped with a type N connector located at the
rear of the rack. The RF ATSC Compliant Mask Filter and output Directional Coupler(s) are
provided with the transmitter and are to be located and mounted at the customer discretion.
Pineapple Technology recommends the filter be securely mounted above the transmitter cabinet
but not in a position that could inhibit air circulation from the top of the cabinet. The directional
coupler is usually mounted on the output of the mask filter convenient for connection to the
station antenna transmission line. Two cables have been provided for connection between the
output directional coupler monitor ports and the DXDPRO-10U Modulator. Conditions vary from
site to site so some engineering may be required to ensure that the antenna is receiving the
correct amount of power to comply with FCC licenses and to ensure safety from lightning, etc.

VII. DTXPRO-10U SERVICE REQUIREMENTS
Routine maintenance of the DTXPRO-10U consists of cleaning or replacing the air inlet filter. In
normal operating environments this should be done once a month or more often in dusty
environments. Cleaning should be done with a light detergent. Rinse and dry the filter carefully
before installing. Any detergent residue could damage components in the modulator. For this
reason, the first option should be to replace the filter with a new one (PTI Part Number 990202)
The following data should be recorded in the station log. This information should be compared to
previous test recordings to insure normal operations.

Under normal operating conditions is the performance of the adaptive linear and non- linear
correction performance should be checked. This can be done remotely if the unit is connected
via Ethernet or on each visit to the site. Adaptive linear correction is normally placed in the idle
mode once the correction is complete. If so, the corrector can be placed in AUTO RUN for a
while to optimize the correction and then returned to the idle mode.
