Transition cards

The MVME system serial I/O uses various transition cards to route signals to standard external connectors such as DB25, DB9, and RJ11 (teledapt).

The transition cards available are the MVME712M, MVME712A, MVME712AM, MVME705B and NT6D51AA. These cards have specific capabilities and hardware configurations. The descriptions and illustrations of these cards follow.

MVME712M transition card

This new transition card (shown in Figure 20) provides an interface between the SBC card and peripheral devices such as the system console. It connects to the J2 connector of the SBC card through the P2 adapter board.

The MVME712M card faceplate provides four 25-pin connectors. Connectors SP1-3 are for asynchronous serial ports 1Ð3; connector SP4 is for synchronous/asynchronous serial port 4. The MVME712M card does not contain an internal modem.

This transition card also provides an Ethernet connection.
