NAME

q3302orb - acquire data from a Quanterra/Kinemetrics Q330 datalogger to an ORB

SYNOPSIS 

q3302orb [-pf pfname] [-calib_db dbname] [-dlclock dlname] [-v]
         targetname [orbtag1 orbname1 [orbtag2 orbname2 [...]]]

DESCRIPTION

q3302orb is a program for interacting with one or more Quanterra/Kinemetrics Q330 dataloggers. Data packets along with log messages, status messages, command responses and debug messages are written to a set of output ORBs. A large set of status channels can be generated as regular ORB waveform packets and, ultimately, archived as miniSEED files in the same manner as the seismic waveform data. Remote command and control of the dataloggers is accomplished through ORB-based command/response packet communications.

OPTIONS

ORB OUTPUT AND INPUT PACKETS

q3302orb writes out waveform data in either GENC (generic compressed) or MGENC (multiplexed generic compressed) packet formats, as specified by the parameter file. (Note that these are the only output formats that are supported at this time.) For each datalogger, individual SEED channels may be either preserved as individual ORB packets, or they may be multiplexed together in an arbitrary fashion. Although the dataloggers always put out one-second data packets, q3302orb can be configured to package waveform data into ORB packets of arbitrary time duration. q3302orb allows for specification of a subcode in the source name for each packet type (see join_srcname(3)) so that multiplexed packets with different collections of channels from the same datalogger can be uniquely identified through their ORB source names.

In addition to the seismic waveform data, q3302orb can also be configured to generate regularly sampled channels of status and state-of-health trace data that are either obtained directly from the dataloggers or are generated internally by q3302orb as it acquires data. These status waveform channels can be written out as regular ORB waveform packets and can be multiplexed arbitrarily with arbitrary time durations just like the real seismic waveforms.

q3302orb writes out a set of log messages as <target_name>/log packets, for log messages relating to the q3302orb instance and as <datalogger_name>/log packets, for log messages relating to Q330 dataloggers. These messages are simple ASCII strings. These log messages can be displayed by the program dlmon(1).

q3302orb keeps a set of status information for each attached datalogger. All of this status information is written as a parameter file packet (with name <target_name>/pf/st) to the output orb at regular intervals. These status packets can be displayed by the program dlmon(1).

q3302orb reports configuration information when commanded. This configuration information is written as a parameter file packet (with name <datalogger_name>/pf/cf) to the output orb when requested.

q3302orb writes out certain debugging information as parameter file packets (with names <datalogger_name>/pf/fr and <datalogger_name/pf/frst) to the output orb at regular intervals when debugging is enabled.

Commands to q3302orb and to the attached dataloggers are all read by q3302orb from the command ORB with name <target_name>/pf/cm.

PROGRAM PARAMETER FILE

The q3302orb parameter file contains all of the information necessary for connecting to and acquiring data from the Q330 dataloggers. Following is an example q3302orb parameter file.

# Note: disposition is as follows:
#	"nothread"	= Don't start thread for this datalogger
#	"startthr"	= Start thread for this datalogger, but don't start acquisition
#	"startacq"	= Start thread and acquisition for this datalogger

#   Following are individual datalogger overrides:

BR_BQ330 &Arr{		# associative array with dlname as key
	local_port_control		37498	# local port no. for control sockets
	local_port_data			37499	# local port no. for data sockets
	throttle			512000	# q330 communications throttle in bits-per-second
}

The first part of the parameter file consists of a set of default values that will be used by all dataloggers and also a set of datalogger packet format and template definitions that are used to define which channels are acquired and how the individual SEED channels are written to the output ORB packets. The second part of the parameter file consists of a single dataloggers table that defines each of the individual Q330s for acquisition. The third part of the parameter file lists individual datalogger parameters that override the parameters specified in the previous two sections.

Parameters from the default section of the parameter file are as follows:

These default parameters define an acquisition "template" which we assign the token default. The default template can be used for any and all of the dataloggers if desired. Other acquisition templates can be defined through the datalogger_templates associative array (see below). This provides a convenient mechanism for defining a set of "default" configurations. For example, this becomes useful in situations where both three-channel and six-channel Q330 units are being acquired from the same instance of q3302orb.

Once all of the default parameters and the datalogger templates have been defined, it is relatively easy to set up acquisition from a particular set of Q330 dataloggers. This is done in the dataloggers table which is defined below:

Finally, any of the parameters can be overridden for particular dataloggers. This is done by specifying associative arrays whose names are set to the dlname fields in the dataloggers array. The contents of these associative arrays can contain any of the global default parameters which causes the values for those parameters to be overridden only for the specific datalogger.

BUGS AND CAVEATS

For those running the Antelope 4.4 pre-release version of q3302orb, the MGENC packet format is not enabled (this format is not understood by the 4.4 version of libPkt). Therefore, for the 4.4 version, multiplexing is not allowed.
