These menus are displayed during power up for few seconds.

The second menu gives indication on product:

- product id (MTB40),

- the firmware release (ex. 1.30.0A),

- the band in extended format and

- the serial number.

Keep selector pushed to hold this menu!

<STATUS> menu

This is the first menu displayed after power up.

Major info are displayed:

- Current channel/group or the receiver name if the MTB40 is already synchronized with a receiver

- Current frequency (i.e. 566.000 MHz)

- Mic gain (i.e. AF: -04 dB) and high pass filter (i.e. HP: Flat Hz)

- “RF 50” or “RF OFF” on top right if RF transmission is ON or

OFF

- Batteries charger (a bar with 7 level)

<PRESET> menu

This menu can be entered by pushing .

MTB40 can recall configuration presets.

“FACTORY” recalls the Wisycom factory configuration.

“USER” recalls the user configuration (the transmitter configuration is copied into the USER using the “save to” submenu).

All “USER” menus are not locked by default, thus this is quick way to unlock features!

When the user changes some parameters from the PRESET configuration (for less than frequency) an asterisk appears on the top-right corner until a save command is executed.

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

(using the programmer UPK 300/UPK

Mini or the receiver MRK950/MRK960).

We provide the device with some preset configurations specifically designed for certain types of microphone or applications (it’s possible to change these presets in any time using the TX manager).

All parameters can be “left unchanged”, “changed” or “changed and lock”, allowing a very flexible way to pre-program MTB40 configuration.

Wisycom TX Manager allows to read, modify and update the configuration of Wisycom transmitters.

It is necessary to

 connected the programmer UPK300E/UPK

Mini or the receiver MRK950/MRK960 to the PC thru USB connection

 run the Wisycom TX Manager

 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 the image below):

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

MTB40 User Manual

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 (

❶

)

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.

In this panel it’s possible to assign a name to the TX (not available for FW v.1.22.0F or previous).

Under this parameter, there is a flag to hide the info menu on the TX (not available for FW v.1.22.0F or previous)

CURRENT SETTINGS PANEL (

❷

)

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 or hidden clicking the related lock/hidden button, so the set value cannot be changed next or cannot be visible on 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.

12

MTB40 User Manual

TUNING FREQUENCIES PANEL (

❸

)

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!

13

MTB40 User Manual

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.

MTB40 User Manual

PRESETS PANEL (

❹

)

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).

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.
