Functional Description
3.1 Overview
This chapter provides information on MVME761 transition module and SIM circuitry, P2 signal
multiplexing, and the configuration of the serial ports.
3.2 Circuitry
The MVME761 transition module and the Serial Interface Modules (SIMs) convert the TTL level
signals to and from the MVME5100, and MVME5500 modules to the reception and
transmission levels specified by the appropriate port interface standard.
The MVME761 transition module contains a small amount of “house keeping” circuitry. Bulk
capacitors are on the power sources (+5Vdc, +12Vdc, and -12Vdc). Pullup resistors put the
inputs to the host board in a known high even when no SIM is installed.
