 |  It can be used as an I/O extension in any type of bus system- CompactPCI, PXI, VME or on any type of stand-alone SBC
- Appropriate M-Module carrier cards in 3U, 6U and other formats are available from MEN or other manufacturers
- The M77 is a quad serial interface M-Module which supports four high-performance UARTs with RS232/423 or RS422/485 level at the front-panel D-Sub connector or at the rear I/O connector of the M-Module
- The 16C954 UARTs are fully software compatible with 16C550 UARTs
- The interface mode of the M77 can be changed by means of software
- The termination resistor for RS422/485 must be set up through an external connection in the cable
- All interface lines are optically isolated from the system and from each other, which is essential for advanced automotive and industrial applications
- The M77 is equipped with an M-Module-ID EEPROM
