Introduction
1.1
System Overview
The VR2C joins the world of instant communication by allowing received data from
VEMCO’s coded tags to be sent in real time to third-party equipment. That equipment could
be a PC, a serial terminal, a third-party datalogger, or any ASCII compatable device. Along
with tag data, the VR2C can record and send information about the temperature and tilt of the
receiver. How the data is sent is easily customized to fit your needs, and can be setup
whenever you are in communication with the VR2C.
The VR2C retains the submersible plastic corrosion resistant high pressure case VEMCO
receivers are known for while adding a cabled RS232/RS485 external connector. This
connector, along with real-time communication, provides the option of powering the VR2C
from an external source as well as from the receiver’s internal single Lithium D cell battery.
1.1.1
VR2C Modes of Operation
The VR2C is usually in one of two operational modes – either acoustically dormant in Suspend mode or
actively listening and recording detections in Record mode.
1.1.1.1
Suspend Mode
Suspend mode is a low power state used when the VR2C is being
shipped or in storage for an extended period of time. When in
Suspend mode, the receiver will not detect or record tag
information. For details on how to place the VR2C in Suspend
mode, see section 3.1.8 if you are using VUE or section 3.2.5.2.7 if
you are using ASCII commands.
1.1.1.2
Record Mode
Record mode allows the VR2C to detect and record tag information, therefore it is the mode used during
testing and deployment. Because the VR2C is shipped and stored in Suspend mode, where it is acoustically
dormant, it must be put in Record mode before it can detect tags. Instructions for entering Record mode
using VUE are found in section 3.1.6 and the ASCII command is found in section 3.2.5.2.3.
The VR2C is shipped in
Suspend mode with the
internal battery connected.
Always put the receiver in
Record mode (begin a
study) before deployment.
