baud rate is displayed (choice of 9600, 1200, or 300 baud). When the appropriate baud rate is
displayed, press the ENTER key on the keypad.
Log Interval (Option 03B)
If data logging is included in the VR60 receiver (see VR60 Memory (Option 03B) section), a prompt
for the Log Interval is shown on the display requesting verification that the Log Interval is correct.
LOG Int. 0 S
(Y/N)
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.
If the Log Interval is correct, select YES. To change the Log Interval, select NO and enter the
desired value on the keypad (followed by ENTER).
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.
If a Blanking Interval of 200 ms is not desired, select NO a the (Y/N) prompt and enter the desired
Blanking Interval on the keypad (followed by ENTER).
