WISYCOM IR PROGRAMMER (VER. 1.3.1.1 AND ABOVE)

Wisycom IR Programmer allows to read, modify and update the MTP40 Lite device
configuration.

It is necessary to

 install Wisycom IR Programmer (version 1.3.1.1 or above)

WARNING: If it is the first installation and Wisycom USB driver has not already

installed in the PC, install the USB driver (run C:\Program Files
(x86)\Wisycom\MTP&MTH Infrared Programmer (TX)\Drivers\ DriverInstaller.exe)

 connected the programmer PK300 or the receiver MRK950/MRK960 to the PC thru

USB connection

 run the program
 enable the IRDA communication on the transmitter (see IRDA menu)

NOTE: Wisycom IR Programmer doesn’t work whit MRK950/MRK960 if it is connected to the
PC using an ethernet cable.

The Wisycom IR Programmer’s window is divided in 4 parts (see Fig. 5):

❶Interface and Device panel contains all the major information of the connected device

❷Current Settings panel shows the current configuration. Thanks the PRESET panel, a

previous saved configuration can be chosen and loaded like current setting.

❸Tuning Frequencies panel allows to handle Groups, Channels and Frequencies

❹Presets panel allows to read, change and save different configurations

Figure 5: Wisycom IR Programmer’s window

10 different configurations are available:

• FACTORY configuration is a locked configuration: no parameter can be changed.
 USER configuration is the only configuration that can be saved using the OLED display (see

<PRESET> menu). Note: It is not possible to change the name of this configuration.

 Other 8 configurations where the user can change both the name and the values of all

parameters.

INTERFACE AND DEVICE PANEL

At the beginning, the program checks which IR devices are detected and they appears on the
Interface panel.

The user has to select the device and push <connect> button in order to open the
communication with the IR device. A picture on the top in the Interface panel help the user in

this selection showing the type of devices detected. During this process the “IR activity” led
blinks to indicate that the program wait connection’s answer from the IR device.

A successful connection is signaled with the “interface connection” green led, while a failed
connection is signaled with the “communication error” led.

Once a supported device is found, the software automatically reads all the data related to the
remote configuration, as well as the frequencies that are pre-programmed.

Firstly, in order to avoid unwanted operation, no parameters can be changes and the EDIT
button, presents on the bottom of Device panel, is yellow and set to LOCKED state. Pushing
the EDIT button, it becomes grey and sets to UNLOCKED state to indicate that the
configurations can be modified.

CURRENT SETTINGS PANEL

In the Current Settings panel the user can

 with Preset panel → load one of the 10 available configurations
 with other panels → modify all the configuration’s parameters (the same that are

changeable in the OLED display). Each parameter can be locked clicking the related
lock button, so the set value can not be changed next using the OLED display.

ATTENTION: All the modifies applied to the Current Settings panel are instantaneous: they are
applied directly to the device and save in its memory but no saved in the preset configuration.

TUNING FREQUENCIES PANEL

With the Tuning Frequencies panel the user can select a frequencies group (0÷39) and for each
one execute the following operations:

- modify the Group’s Name

- lock and/or hidden the group

- for each channel (0 ÷59) of the selected group: change the frequency value and the

related status (locked/hidden) (in the center grid frequency)

The SAVE button, at the top of the
panel, save the changes of the group
selected (name group, lock/hidden
group).

To change a frequency
value for a specific
channel: double click
on the grid frequency

panel (row=channel’s

number), insert the
new frequency value
and press OK button.

To lock/hide a specific
channel, double click on the
grid frequency panel.

NOTE: keeping pressed the CTRL button on the keyboard and clicking the wanted
channel/group shown on the frequencies grid, the tuning process is executed. It is equivalent
to configure the Tuning in the Current Settings panel but it is easier. The device is re-tuned
immediately, so be sure that the RF power is turned off while changing frequencies with other
RF systems in use around you!

If the currently tuned channel is on the same group that is listed on the grid, the background
color of the related cell (channel) on the grid becomes yellow.

Using the LOAD/SAVE button, at the bottom of the panel, it is possible to load/save the
frequencies for the selected group from/to a .wdf file. To save the frequencies of all the groups
click to the related button above. The legacy option save the channels without the hidden/lock
info.

PRESETS PANEL

The Preset panel allows to manage all the 10s available configurations.
For each configuration it is possible to set the name and all the parameters value except for
FACTORY and USER configurations (see table below).

* Be careful to write a meaningful name for the preset because the name will appear on the
settings list of the device menu! Please, avoid empty names.

If a parameter is “locked”, it cannot be modified by device menu (using OLED display), while if
“don’t care” propriety is active, when the user load the configuration, the parameter’s value
doesn’t changed.

ATTENTION: Changes are applied only after a “save” action.
NOTE: “a trick” In case of the user have a locked parameter and he is in great need for modify
it, he can save the configuration to USER configuration by OLED (see PRESET menu) and then
load the USER configuration (in this way all the parameters have the lock propriety disable and
the user can modify all the parameters).

FILE MENU

Using a file menu at the top left of
the panel it is possible to load/save
all the configuration values of the
device to/from a .wcf file (Wisycom
Configuration File).

Save a .wcf file

With an infrared device correctly connected, select File->Save User Configuration and select
the destination file.

Load a .wcf file

To load a user configuration select File->Load User Configuration and select a previously saved
data file; a form will be shown, where it's possible to select which data has to be restored and
which skipped. This allow the user to load a particular configuration while keeping other data.
