7 Common Questions
7.1
VUE related questions
7.1.1 How/when do I change my receiver code map?
Receivers must be configured with a Code Map that defines which type of tags the receiver can detect. Check
www.vemco.com for details on currently supported Code Maps and choosing the proper map for your study.
Changing a receiver map is not done often and should be done with careful
attention. Setting up a receiver with an incorrect map may result in no detection
data, which would not be discovered until you either communicate acoustically
and check the number of detections, or retrieve the receiver and offload your data.
WARNING
Setting up a receiver
with an incorrect map
may result in no
detection data.
When a receiver is configured with a new map, the data logs are automatically
erased as they are no longer valid in the presence of a different code map. Please
offload stored data prior to installing a new code map.
Detailed instructions on configuring your receiver with a new code map are located in section 6.7.
7.1.2 What is initialization?
Initialization, which is also referred to as starting a study, is an important step required to configure your
receiver correctly. During initialization, you can input the station name (location) where the VR2AR will be
deployed, and set the receiver clock based on your computer clock. The receiver
clock is always updated based on your PC clock during the initialization process.
WARNING
This information will be resident with the VR2AR and will be available during
offload, regardless of whether you use the same computer or not. Initialization
Offload your data first!
also erases the receiver log files so be sure to offload data from your receiver

before initializing it. When data is offloaded from a receiver, the VRL file
created contains information about how the receiver was initialized.
If a VR2AR receiver is deployed without being initialized, the receiver will detect tags but will not
necessarily have the correct clock setting or map configuration required for proper data detection.
7.1.3 Why does VUE create two .vrl file types?
When a VR2AR is offloaded, VUE creates a detection file and an RLD data file. Both files have the “.vrl”
extension. VUE only imports the detection vrl file (e.g., VR2AR69_800001_20140120_1.vrl or
VR2AR_800001_20140120_1.vrl ). The RLD data file (VR2AR69-RLD_800001_20140120_1.vrl or
VR2AR-RLD_800001_20140120_1.vrl) is used by VEMCO for diagnostic purposes and should be archived
in case it is required by our Support Department. The RLD data files have the letters “RLD” in the filename.
