NTRODUCTION

“MTP41 is an extremely small and light pocket transmitter especially designed for

professional wireless microphone applications”

Very easy and quick to use thanks to OLED display, dedicated buttons and a joggle selector.

MTP41 benefits also of the latest Wisycom RF technology along with an enhanced robustness against noise and inter-modulation.

The other 8 configuration presets are user programmable thru the infrared and the

PC interface (using the programmer UPK 300 or the receiver MRK950/MRK960).

All parameters can be “left unchanged”, “changed” or “changed and lock”, allowing a very flexible way to pre-program MTP41 configuration.

ISYCOM IR PROGRAMMER

(

VER

.

1.3.2.0

AND ABOVE

)

Wisycom IR Programmer allows to read, modify and update the MTP41 device configuration.

It is necessary to

 install Wisycom IR Programmer (version 1.3.2.0 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 UPK300 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):

❶

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

❷

Current Settings panel shows the current configuration. Thanks the PRESET panel, a previous saved configuration can be chosen and loaded like current setting.

❸

Tuning Frequencies panel allows to handle Groups, Channels and Frequencies

❹

Presets panel allows to read, change and save different configurations

Rev.01

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.

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.
