1.1.2 Programming using automatic programming mode

The latest generation of Marmitek X-10 modules can be (re)programmed by means of a special procedure without having to
remove the module. This procedure, which must be followed precisely, is based on interaction between the PMIX35 and the
module. The module can be programmed by operating a switch or pushbutton, or by switching the connected load on and off
(in electrical wall sockets), in combination with the software. The module will not enter the programming mode if any of the
conditions have not been met.
Read through the instructions below carefully and follow them precisely.

• Press: and repeat the instructions above or

• Press the programming button of the module within the time indicated by:

The PMIX35 makes three attempts , before stopping the procedure.

1.2 Analyzer

The purpose of the Analyzer tab page is to measure and analyse the quality of the data transfer over the power line. For a
good analysis, various settings can be made, in many cases requiring specific knowledge. Where in the installation the
measurement is carried out is also important.
All measurements take place via the power cord of the PMIX35.

The explanation of the application of the Analyzer function is divided into a number of practical components. The table below
gives an overview of these components and their possibilities:

Component Possibilities

Measuring signal levels The signal levels of all messages transmitted and received are displayed in the log screen. In this way, unreliable

signal levels are immediately noticeable. By varying the transmission level of the transmitted messages, the

sensitivity of the receiving side of a module can be measured.
Network diagnostics The network diagnostic indicators offer direct insight into possible areas of interest.
Sending and receiving Messages can be sent directly or be placed in a macro before they are sent. The macros can be sent
messages automatically at certain intervals. Messages that are transmitted and received can be found in the log screen.
Logging and viewing The status of the received messages is indicated in the log screen by means of colour shading.
message communication In this way, communication faults are immediately noticeable. The saved log file can be imported into Excel,

for example, for further analysis.

Table 1 3: Analyzer components.

1.2.1 Measuring signal levels

The measuring of signal levels in Marmitek X-10 installations allows the rapid detection and resolution of problems. A few
examples of this are:

• One or more modules appear to be inaccessible after switching on one module.

• Switching this module On has an affect on various signal levels. The load connected to this module is causing the problem.

• Some of the modules do not work at certain times. The signal levels of some of the modules lie below the required level.
At the times when these modules do not respond, the noise level is shown to be much higher.

The automatic measuring of the signal quality can be performed most simply via the network validation tab page.
See chapter 1.3.

The measuring of signal levels can also be performed for individual modules. This procedure is described below.

1.2.1.1 Signal levels of modules

The signal level and noise level of each message received is measured. These values can be found in the log screen as well
as in the log file next to the received message. These values are reported in mV.
The readings from the two most recently received messages can also be found on the large display fields in order to quickly
gain insight into current events. An important factor in power line communication is network impedance. The value of the
power line impedance is reported in Ohm (see figure 5).

During measuring, always take the following points into account to be able to properly assess
the signal level of a module:

• Before the measuring starts, switch all appliances in the home on. By doing so, the effect of
the switched on appliances is included in the measurement.

• Perform the same measurement at more than one socket in the home.

• Always look at the noise level. The higher the noise level, the more signal is necessary to be
able to function properly. It can happen that an appliance has a negative effect on the noise
level and, therefore, communication. Provide this appliance with a filter.

• Always look at the network impedance. It can happen that an appliance has a negative effect
on the network impedance and, therefore, communication. Provide this appliance with a filter.

Figure 5:
Display of latest readings.

For maximum reliability, the signal levels must comply with the threshold values as indicated in figure 6. If the signal level
falls into the yellow area, it is important to check whether the module continues to function properly in all cases. If the signal
level falls in the red area, action must always be taken to improve the signal quality.

• The network impedance should not be lower than 2 Ω.

Fault Check Good

0 100 mV 200 mV Max

Figure 6: Signal level thresholds for modules.

1 Programming and measuring functions

1.2.1.2 Sensitivity of modules

The sensitivity of modules can be measured by varying the transmission level of the messages. By doing so, it is possible to
determine at which level the module no longer reacts. To do this, slide the selector from left to right (see figure 7).

Follow the steps below to measure the sensitivity of a module starting from the measurement
site:

1. Enter ON/OFF or Status Request commands in the command lines for controlling the relevant
module (see paragraph 1.2.3.2 Sending several messages simultaneously). For interface
modules, make use of following the status.

Figure 7:
Setting the transmission level.

3. With the selector, find the lowest point at which the module still responds properly. Take the value of the transmission
signal from the display field below.

4. Check where this value falls within the thresholds depicted in the figure below:

Good Check Fault

0 2 V 4 V Max

Figure 8: Sensitivity thresholds of modules.

2. Slide the "Transmit Voltage" selector all the way to the right (maximum) and send several
ON/OFF commands to check the operation of the module. The signal level sent is then
displayed in the large display field underneath.

5. If the signal level falls into the yellow area, it is important to check whether the module continues to function properly in
all cases.

1.2.2 Network diagnostics

The Network Diagnostics indicators and the Counters (see figure 9) offer quick insight into specific events.

Figure 9: Network diagnostics data.

The table on the below gives an overview of the diagnostic indicators and their functions. The indicators are displayed until all
indicators are reset with the button.

Indicator name Diagnostics

Repeater detected Indication that the signal level measured from the 2nd address/command received is higher than the 1st over the

course of several measurements.
Module noise detected Indication that the PMIX35 detects signal interference that disrupts communication.
Lost command detected Indication that a suspect message has been detected in the log screen, indicated by red shading.

Lines shown in this colour require extra attention.
<200 mV detected Indication that a signal lower than 200 mV has been measured.
<100 mV detected Indication that a signal lower than 100 mV has been measured.
Impedance drop detected Indication that the impedance measured changes a specified delta X.

Example:

Follow the steps below to automatically send two command lines to the address "A01".

1. Follow the steps in paragraph 1.2.3.12 to provide both command lines with the required messages.

2. Select the option and the required delay time for the first command line:

3. Select the option and the required delay time for the second command line.

4. Start automatic sending by clicking: (this symbol then becomes: ).

5. The indicator for the command lines indicates in yellow which line is waiting to be sent.

6. Sending can be cancelled by clicking: (this symbol then becomes: ).

1.2.3.4 Receiving messages

As well as messages that are transmitted, messages that are received are also displayed, with their arrival times,
in the and columns in the log window (see figure 13).

Figure 13: Received messages log screen.

According to the X-10 protocol, messages are always sent twice consecutively. The first message always appears in the

column and the second message always appears in the column. If the second message is not

received, the second column will be empty. Single messages occur normally with Phase Couplers and Repeaters.

See the table below for an explanation of the different data colours in the log screen.

1.3 Network validation

In this tab page, a quick and simple network analysis can be performed before the delivery of a Marmitek X-10 installation.
By making a selection of the addresses used, the PMIX35 will perform a number of measurements and present a report
which includes the areas of interest of the Marmitek X-10 installation.

1.3.1 Performing network validation

When performing network validation, the tab page "Network validation" must first be selected. Select the letter codes used in
the Marmitek X-10 installation by clicking the relevant boxes, thereby selecting the letter code(s).

In the fields on the top right corner, the name and address details of the customer where the measurement is taking place
can be entered. Any comments can be entered in the remarks field. Once the measurement is complete, this data can be
saved and compared with the data from any subsequent measurements.

!

Please note:

Before validation can be started, it is important to switch on all of the appliances in the home that are connected to the
power line. Switching on means bringing the appliance to working voltage, as opposed to leaving them in stand-by mode.
Appliances such as dishwashers, washing machines, dryers, computer monitors, TVs etc. must be switched on. In this way,
the measurement will be made under the most adverse conditions, so the result gives a good picture of the points that
require attention to guarantee reliable data transfer.

Figure 14: Network validation tab page.

Press "Start Validation" as soon as all appliances in the home have been switched on. The PMIX35 will now begin
transmitting data to and receiving data from the modules that are present in an installation. This process can take up to
10 minutes or so depending on the number of letter codes.

!

Please note: Make sure that no switches are operated during this process and that any motion detectors are not

activated while the measurement is being made. Do not interrupt the test; allow the PMIX35 to run through the entire process.

15

1 Programming and measuring functions

1.3.2 Interpreting the network validation data

The PMIX35 software will display the transmission, reception, noise and impedance levels per address.
In the "Result" column, the software displays the result of the measuring process for the relevant address.

There are four possible results, namely:

• Not Found: the address was not found in the installation. The line is coloured white.

• Passed: the results are good. No further action is necessary. The line is coloured green.

• Check: the results give cause to re-examine the situation around the module at this address. The line is coloured orange.

• Failed: the results indicate that under the current circumstances no reliable communication is possible to and/or from this
module. The line is coloured red.

The result is established by an analysis of the software on the basis of the signal level and noise level. As soon as there are
low signal levels, the result is clear. However, it can also occur that the signal levels are good (above the minimal values) but
that there is a very large difference between the signal levels of an ON and an OFF command in a module. The PMIX35
software will also indicate this address as "check".

It is advisable to repeat the validation test for the modules that receive a "check" or a "fail" result. Before repeating the test,
switch off one or more appliances in the vicinity of the module you wish to check. If the repeat validation gives a better
result, this means that the appliances in question have a damping effect on the signal quality. Isolate the appliances with one
or more filters. If the signal levels do not change after switching off the appliances, this can mean that there are other factors
causing the signal strengths to be inadequate. In this situation, a signal amplifier (SVX10) can offer a solution to improve the
signal levels.

The measurement data can be saved by clicking the button. Another possibility is to select the data and copy and paste it into
a spreadsheet program.

2 The PMIX35 as data interface

The PMIX35 supports the CTX15/35 protocol as standards and, in addition, has a number of extra functions. This means that
the PMIX35 can directly replace the CTX15/35 without having to adapt the software.

2.1 PMIX35 communication driver

The PMIX35 is equipped with a USB connection based on a CP210x virtual COM port. The installation software automatically
installs the CP210x USB to UART Bridge Virtual COM Port (VCP) drivers, so that the PMIX35 can communicate via the USB
port of a PC.

The drivers are available for the following operating systems:

• Windows 2000/XP/Server 2003/Vista

• Macintosh

• Linux

During the installation, the software also checks whether the firmware version which belongs with the installed software is
loaded in the PMIX35. If this is not the case, the software will load the correct firmware version.

2.1.1 Example using Windows 2000/XP driver

After the installation of the USB drivers on the Windows XP operating system, the name of this COM port can be found
under "Device Manager" in the hardware overview in the configuration screen in XP (see figure 15).

Figure 15: Windows XP Device Manager USB Driver.

The COM port number assigned to the PMIX35, COM5 in this case, follows the driver name "CP2101 USB to UART Bridge
Controller". Now, communication with the PMIX35 can occur via this COM port.

2.2 Protocol description

2.2.1 COM port settings

See the figure below for the required COM port settings:

Figure 16: Port settings.

2.2.2 COM port detection

The COM port to which the PMIX35 is connected can be detected by sending the "PX" command. As the PMIX35 will answer
this command, the correct COM port can be automatically selected.

18

2 The PMIX35 as data interface

2.2.3 Communication format

All communication is ASCII format. The messages between the PC application and the PMIX35 are equipped with headers.
The PC application always takes the initiative and the PMIX35 answers it. See the table below for the format.

$>9000{message}cs# Communication direction: PC -> PMIX35
$ Start character.
> Communication direction from PC to PMIX35.
9000 PMIX35 address.
{message} Message for PMIX35.
cs Checksum: sum of all characters except the end character.
# End character.

$<9000{bericht}cs# Communication direction: PMIX35 -> PC
$ Start character.
< Communication direction from PMIX35 to PC.
9000 PMIX35 address.
{message} Message for PC.
cs Checksum: sum of all characters except the end character.
# End character.

Table 2 1: Format headers.

There are various types of messages, including messages which contain X-10 traffic. These messages contain not only the X­10 format but also the accompanying signal levels. The table below shows the X-10 format:

<L><AA> Address
L 16 letter codes, A to P.
AA 16 addresses, 01 to 16.

<L><CC[C]> Command
L 16 letter codes, A to P.
CC[C] commands: ON, OFF, DIM, BGT, AUF, ALN, ALF, HRQ, HAK, PRG, SON, SOF, SRQ.

<L>[1]<AA><EEEE> Extended
L 16 letter codes, A to P.
AA 16 addresses, 01 to 16.
EEEE Extended code hexadecimal.

2.2.4.1 Sample checksum calculation

To receive data from the PMIX35, a request must be sent to the PMIX35.
This request is described in

$>9000RQcs#

To calculate the checksum "cs", the hexadecimal values of all of the previous characters must be added together
hexadecimally. These values can be found in the ASCII table below:

Subject to technical changes without prior notice.

(*) Marmitek X-10 modules are suitable for use in homes where the ambient temperature in the living area is not higher that 35°C under normal circumstances, or may

(exceptionally) reach a maximum of 40°C.

Undisturbed functioning of Marmitek X-10 automation

Electrical equipment and systems can be sensitive to signals from other equipment, which causes electro magnetic
disturbance. In the European Union, countries agreed upon laws for the immunity (sensitivity) of signals of other equipment
as well as equipment emission (disturbance). When equipment or applications in a certain surrounding comply with the valid
standards, they will not disturb each other's operations (they are called "Electro Magnetic Compatible").
For residential surroundings, where the home automation system Marmitek X-10 is being applied, the European standard for
immunity is standardised in EN 61000-6-1. Equipment that complies with this standard is resistant to electro magnetic
emission of other equip ment, which complies with the European standard EN 61000-6-3 for residential surroundings.
Experience has shown that in domestic surroundings, equipment is being used which has an EMC-emission level that is
above the levels stated in EN 61000-6-3. This equip ment can disturb the correct functioning of the Marmitek X-10 modules.
The immunity of the Marmitek X-10 built-in modules is therefore revaluated and equivalent to EN 61000-6-2 (the more severe
European standard for immunity in industrial surroundings).

Nevertheless, the application area for Marmitek X-10 will remain restricted to residential areas.

Marmitek X-10 is therefore not responsible for the disfunctioning of the Marmitek X-10 system as a consequence of
equipment in the building with emission levels that exceed the maximum allowed levels set as standard for residential,
commercial and semi-industrial surroundings stated in EN 61000-6-3.

Application area Valid European Standard Marmitek X-10-home automation*
