GLOSSARY
Bin Size
The Bin Size is for each coded tag is stored in the firmware of that particular tag and is necessary
for proper reception of the pulse string by the VR60 receiver.
Blanking Interval
The Blanking Interval is the time after each detected pulse in which echoes and reverberations are
ignored. The Blanking Interval should normally be set to 200 milliseconds. In extremely
reverberant areas the Blanking Interval may be increased but not to exceed 75% of the shortest
transmitter period.
Log Interval
The Log Interval controls the rate at which decoded data is sent to memory. The Log Interval may
be between zero and 30000 seconds (over eight hours) and must be entered as seconds. A Log
Interval of zero will store all the decoded data in memory. For example, if a Log Interval of one
minute is desired, a value of 60 seconds must be entered. The decoded data will be stored to
memory every 60 seconds even though the data may be changing at a faster rate on the display.
Sync
The Sync is a value, in milliseconds, which allows the VR60 receiver to receive the acoustic
transmissions of the coded tags (pingers and telemetry transmitters) and identify the type of coded
tag based on the coded map (see
Coded Channels
section). The Sync is stored in the firmware of
each tag.
Print Interval
The time (in seconds) between printing data to the serial port if a printer is setup. The print interval
may be between 0 and 100 seconds and is set in the SETUP routine (see
Setup
section).
