Appendix A: Pulsar Controller
User Interface Overview
The Galaxy Pulsar monitors and controls system components including rectifiers, converters, and
distribution modules via a multi-drop RS485 digital communications bus. System status, parameters,
settings, and alarm thresholds can be viewed and configured from the controller's front panel display.
Assignment and configuration of alarm inputs and output relays can be performed from a laptop
computer connected to a local RS-232 or LAN Ethernet port, or by remote access through a network
connection to the World Wide Web (internet) or your enterprise network (intranet).
This section describes the controller features, functions and alarms from perspective of a user
utilizing the front panel display. All these features are available through the local craft port using Easy
View software or the LAN port using a PC web browser. Easy View is a Lineage Power Systems GUI
provided for local serial port or remote MODEM access.

Voltage
Test Jacks
The display shows the rectifiers -48 voltage (V2) and current. If converters were present, their voltage
would display as V1. The display (V1 versus V2) correlates with test jacks. The large font indicates the
"Primary" or rectifier dc bus; the smaller font shows the "Secondary" or converter dc bus. For systems
with no converters only a single voltage/current pair will be displayed on the front panel along with
the correct test jack association. The other test jack will be unused and will have near zero voltage.
Menu Navigation Buttons
The NE843 has six tactile buttons to use to navigate through a structured menu system. The buttons
serve multiple purposes depending on the screen a user is at. These functions are summarized below.
