Page 4: Mt25C Overview
MT25C devices are membrane keypad tester capable of testing up to 25 dome buttons, capacitive buttons or LEDs. MT25C needs to connect to computer for proper operation. A so ware is provided free of charge to control the MT25C device, display live results and log the history of all testing operations. -
Page 5: Typical Applications
MT25C Typical applications MT25C are typically used to test membrane keypads that include buttons and/or LEDs, but e ectively, they can be used for any application that requires the testing of a number of buttons. The keypad configurations that can be tested are (but not limited to): •... -

MT25C User Manual MT25C MT25C interfaces MT25C devices connect to a host computer via USB port (type B) on the back panel as shown in the image below. Figure 2: MT25C Back panel On the front panel, a standard female DB25 port exposes the 25 test points as well as a status LED. -
Page 9: Principle Of Operation
MT25C is operated via a virtual serial interface (emulated over USB port.) The user can either use a freely available C++ application to configure and use the MT25C device or design his own test system by sending and receiving serial commands over the serial port. -
Page 10: List Of Serial Commands
Command code 0x00 Description This command is sent by the host computer to identify an MT25C device plugged on the serial port. The MT25C shall respond with the following payload: “MT25C” or the bytes array: {0x4D, 0x54, 0x32, 0x35, 0x43}. -
Page 11: Load Configuration
0x03 Description This command is sent by the MT25C device to signal that a keypad was inserted. Please note that in some situations, it is impossible to detect the insertion of a keypad. In that situation, other provisions should be taken on the host computer side (via so ware solutions). -
Page 12: Request A Static Measurement
0x05 Description This command is sent by the MT25C device to deliver the result of a static measurement. The measurement is expressed as a number of pairs. Each pair, consists of 6 distinct values: The first pin number, the first pin state, the second pin number, the second pin state and finally the Voltage drop... -
Page 13: Request A Mechanical Buttons Measurements
MT25C to “mechanical buttons measurement” and scans the keypad for any buttons being pressed. When a button is pressed or released, an event command is sent to host PC. MT25C stays in this mode until the mode is changed. -
Page 14: Request A Capacitive Buttons Measurement
MT25C to “capacitive buttons measurement” and scans the keypad for any capacitive button being touched. When a button is touched or released, an event command is sent to host PC. MT25C stays in this mode until the mode is changed. -
Page 15: Keypad Inserted Event
0x0B Description This command is sent by the MT25C device to signal that a keypad was removed. Please note that in some situations, it is impossible to detect the removal of a keypad (for example, if the keypad has no any LEDs or short circuits). -
Page 16: Unpacking And First Usage
We recommend the user to start by identifying all the di erent components that are provided. To turn ON the MT25C device, connect it to to a free USB port of your computer using the provided USB cable The LED should glow according to the table in the “Status LEDs behavior” section. To switch o the device, simply disconnect the USB cable. - Page 17 MT25C User Manual MT25C Mechanical data MT25C devices casing are manufactured from anodized aluminum, able to withstand heavy duty usage in various harsh environments.
