Appendix H
Central Reporting System
This appendix describes the part the SmartScanIS plays in Union Pacific's Central Reporting
System (aka Automated Detector Monitoring System). Covered are the messages sent to and
received from their host computer.
For a complete description of the Central Reporting System, refer to Union Pacific
documentation. This appendix is only an overview.
H.1 Overview
Union Pacific's Central Reporting System consists of three basic layers. The first layer
consists of the trackside detectors. The second layer is the distributed communication network,
consisting of the railroad's communication lines, commercial circuits, or a combination of both.
The third layer contains the host computer that communicates with each site, processing and
storing the data received.
The SmartScanIS provides support for the Central Reporting System. It sends messages to
and receives messages from the host computer.
H.2 Polling Port (COM2)
On the System Interface board, the DB9M plug P10 (COM2) is dedicated to the Union Pacific's
Polling System. This port supports split baud rate communications providing a Receive baud
rate of 150 to 115200 and a Transmit baud rate of 150 to 115200.
You change the parameters for port COM2 by using the COM2-P10 submenu of the Serial
Ports menu. You can pick a baud rate of 150, 300, 600, 1200, 2400, 4800, 9600, 19200,
38400, 57600, or 115200. You can pick either no parity bit, 8 data bits, and 1 stop bit or even
parity bit, 7 data bits, and 1 stop bit.
