摘要： A power supply board for connecting dry communication lines from a remote station to the electronic equipment at a power station and includes a brushless PM motor mounted in a motor section of the board. The motor is powered by a station-derived low voltage direct current source provided at the power station. A brushless PM generator is mounted in a spaced alternator section on the board. The motor and generator shafts are connected by a flexible tube for generating a voltage suitable for operating of the electronic equipment at the power station. An integrated motor drive circuit is mounted on the motor section and connected to the D.C. source via a protective circuit. The motor has a bank of Hall cell sensors for generating position control signals to the circuit for sequential energization of the three phase motor winding. The output of the alternator is rectified to establish an output voltage for operating the communication equipment. A voltage sampling circuit is coupled to the rectified output and connected by electrical/optical isolators and a fiber optic feedback line to the integrated circuit to create a closed loop system establishing a constant output voltage for operating the equipment.

摘要： A communications adapter for interfacing a transceiver and a line including a synchronous receiver-transmitter programmed by a controller to operate the receiver-transmitter in different data formats during a single frame transmission to or reception from a transmitter/receiver and including logic programmed by a controller for controlling the operation of a transmitter/receiver on a bit level to halt the transmitter/receiver during programming changes of format between and during a frame. For frame transmission to a transmitter/receiver, the receiver-transmitter is programmed for a first portion of a frame for a number of bits per character as a function of transmitter/receiver and line protocol and for second portion of a frame for a number of bits per character as a function of line protocol. For frame reception from a transmitter/receiver, the receiver-transmitter is programmed for a number of bits per character as a function of line protocol and a synchronization pattern as a function of line and transmitter/receiver protocol.
