MEN announces M-Module with four serial interfaces

The M-Module M77N has been developed according to the ANSI Mezzanine standard and extends the carrier board by four electrically isolated serial interfaces, which can be adapted to the requirements by software.

The M-Module M77N supports four high-performance UARTs with RS232 or RS422 / 485 interfaces, implemented in the FPGA. These are accessible via a D-Sub connector at the front and can be connected to the carrier card, and to the backplane of the system via a 24-pin on-board connection, if required. The interface mode of the M-Module can be changed by software, adds MEN.

The serial lines have been optically isolated, which is essential for use in automotive or industrial applications as well as in mobile environments, for example, to protect the control system from external disturbances such as high voltage pulses.

All components of the M77N are soldered against shock and vibration, and are approved for a temperature range of -40 to +85 degree C.

M-Modules is an ANSI-VITA standard introduced in 1997. The standard is particularly suitable for the connection of binary and analogue process I/O, robotics, motion and measurement functions. Mezzanine modules are an extension to all common bus systems such as CompactPCI, ComapctPCI Serial, VMEbus or independent SBCs.
