NAME
pcaRtClient - PCA real-time client for Science Monitoring
and Health and Safety
SYNOPSIS
pcaRtClient [-ascii] [-daemonize] -display-client name
-host hostName [-port number] -name clientName [-read-from-
stdin]
DESCRIPTION
The pcaRtClient process is used primarily as the interface
between the real-time server and the EDS-PCA display clients
for Science Monitoring and Health and Safety. It receives
data packets of the type specified by the -name option, and
assembles a partition, which it then sends to the display
client.
OPTIONS
Options may appear in any order on the command line.
-display-client name
This is the name of X client program to execute
for graphical display. The choices are as fol-
lows:
pcastd1CalS: Standard Mode1 Calibration
pcastd1LC: Standard Mode1 Light Curve
pca1FFT: Power spectra (Temporal Science)
pcaStd1LeahyHist: Power spectra History
pcastd2: Standard Mode2 Spectra
pca2Rate: Standard Mode2 Rates
pcaSBase: Spectral Science - Base
pcaSColor: Spectral Science - Colors vs Time
pcaSHist: Spectral Science - History
pcaSRecom: Spectral Science - Recommend
PCAdisplay: Housekeeping (This is default)
-host hostName
This is the name of the computer on which the
Realtime Server is running. This option must be
specified unless -read-from-stdin is set.
-port number
This is the port number to connect to the real-
time server.
-name clientName
This is the name you advertise to the realtime
server to indicate which kind of data you would
like to receive. The name must correspond to an
entry in the $SOCHOME/etc/RT.CLIENTS. The choices
are EDS-EA5 (or PCA-STD1) for Standard Mode1

pcaRtClient(1) User Commands pcaRtClient(1)
Science data, EDS-EA6 (or PCA-STD2) for Standard
Mode2 Science data, and PCA-HK for Housekeeping
data.
-read-from-stdin
Read from stdin instead of over a socket. Used
mainly for testing and debugging. Also, this
option should be used for archived data.
-ascii Produce ASCII output to stdout, instead of
displaying data on the graph. This is used mainly
for testing and debugging.
-daemonize
Run as a daemon.
ENVIRONMENT VARIABLES
DISPLAY This sets the machine and screen on which any X
Windows opened by the display-client
SOCHOME This is the root directory of the XTESOC Integra-
tion and Test directory. Below this directory,
there should be a subdirectory, etc , which should
contain both the AUTH.HOSTS and RT.CLIENTS files.
SOCOPS This is the root of the SOC operations directory
tree.
FILES
$SOCHOME/etc/AUTH.HOSTS
machines authorized to connect to the Realtime
Server.
$SOCHOME/etc/RT.CLIENTS
table mapping of 'clientName'(see above) to their
ApIDs.
EXAMPLES
To collect Standard Mode1 PCA Science telemetry data from a
realtime server running on xitserv and put up a Light Curve
display:
pcaRtClient -host xitserv.nascom.nasa.gov -port 5094 -name
EDS-EA5 -display-client pcastd1LC
To collect Standard Mode2 PCA Science telemetry data from a
realtime server running on xitserv and put up a Spectra
display:
pcaRtClient -host xitserv.nascom.nasa.gov -port 5094 -name
EDS-EA6 -display-client pcastd2

To monitor stored data: (In this case, pktgen process does
the real-time server role of feeding packets to the
pcaRtClient.)
pktgen -millisleep 500 -write-to-stdout std2-PCA5.1a55189 |
pcaRtClient -read-from-stdin -display-client pcaSBase

AUTHOR
The realtime client template was written by Mike Lijewski.
MIT is responsible for the original version of the client
specific realtime clients. (such as std1Calibration,
std1Timing, std2RTclient, etc.)
All these individual clients were merged together by David
Hon(Hughes/STX dhon@xero.stx.com) to create a combined real-
time client program for PCA, pcaRtClient.
Minor modifications were added by Hwa-Ja Rhee(Hughes/STX
rhee@pcasun5.gsfc.nasa.gov) to accomodate all PCA display-
clients.
