Product details

Motorola's MVME712M is an I/O switching module designed for Motorola's MPU VME module, VME processor module, embedded controller, and single-board computer (SBC) family of processor modules. This module has the following notable features:

Four 25-pin Multi-protocol EIA-232-D serial ports: The MVME712M is equipped with four 25-pin serial ports that support the multi-protocol EIA-232-D communication standard. This allows users to flexibly connect multiple serial devices for efficient data transmission and communication.

Extensive compatibility: The module is compatible with a variety of Motorola VME modules, including MVME147, MVME1600, MVME162, MVME2600, MVME167, MVME2700, MVME177, MVME3600, and MVME4600. This broad compatibility enables users to easily integrate the MVME712M into existing VME bus systems.

Processor module and peripheral interface: The MVME712M serves as the interface between the processor module and its peripherals, simplifying the need for external customer cables. It offers industry-standard rear panel connectors, making connections more convenient and reliable.

Signal routing and configuration: Through the P2 adapter assembly, the MVME712M is able to route the I/O signals and ground wires on the P2 connector from the VME module MPU connection on the chassis backplane to the module itself. The MVME712M then routes these signals to four serial ports, which are implemented via four industry-standard DB-25 connectors on the front panel. The serial port can be configured as EIA-232-D DTE or DCE via a jumper on the MVME 712M. In addition, the MVME712M front panel is equipped with Ethernet ports, SCSI ports and printer ports.

Internal modem connection: The MVME712M also routes the signal from EIA-232-D port 2 to the internal modem, providing more communication options.

P2 adapter board requirements: When the MVME712M is used, the P2 adapter board must be combined with the MVME712M, which is not included in the module. P2 adapter board has the following features:

A SCSI cable connector is provided to allow users to connect other SCSI devices or the MVME712M via a flat ribbon cable.

Equipped with a SCSI termination resistor mounted in the socket for configuration at the end of the cable or in the middle of the cable.

Terminator power is provided by the +5V DC on the P2 connector and is fusing protected (1A) on the P2 adapter board.

Connectors for EIA-232-D ports, printer ports, SCSI and Ethernet signals are provided to interface with the MVME712M.

Overall, Motorola's MVME712M I/O switching module is a powerful and versatile device that provides users with a flexible serial communication and data transfer solution. Whether in industrial automation, communication equipment, or other scenarios requiring VME bus connections, the MVME712M performs well to improve the overall efficiency and stability of the system.
