SYSTEM OVERVIEW
The VR60 Ultrasonic receiver is intended to receive underwater signals transmitted from pingers,
location markers, data telemetry transmitters, and other similar devices over a frequency range of 10
kHz to 100 kHz. The VR60 receiver is designed to operate with a hydrophone containing a high
gain, low noise pre-amplifier powered by the receiver. An omnidirectional test hydrophone is
provided as a standard accessory (VH65). An optional V10 or other directional hydrophone, when
used with the signal strength indicator on the receiver front panel, enables the VR60 receiver to
locate and track a transmitter.
An optional
Decoder/Display
unit (Option 01) provides pulse interval timing and alphanumeric
display of transmitted data, such as depth in meters or temperature in degrees Celsius. A serial RS-
232C compatible interface provides communication to, or control by, a remote terminal or general
purpose computer. The serial interface can also be connected to a printer to log data on paper.
A VR60 receiver equipped with 256K of memory (Option 03B) is capable of saving received data
for later viewing on the receiver or downloading to a computer.
Data from coded transmitters can be received when the VR60 receiver has been equipped with
coded capabilities (Option 07). This allows the receiver to detect a larger number of transmitters on
a single frequency.
