AVAILABLE VR60 RECEIVER OPTIONS

There are seven options available with the VR60 receiver.  These options are listed below, and are
explained in detail in the sections to follow.

Option 01:
Option 02:

Option 03B:

Option 04:
Option 07:
Option 08:

Internal Telemetry Decoder and Display.
Internal rechargeable battery (AC charger module also supplied).
256K CMOS Memory with independent battery backup and data logging
firmware (requires Option 01). 
Additional hydrophone cable length available at time of manufacture.
Coded transmitter capability.
Non-standard preselected frequencies in the CHANNEL switch.

It is possible to combine certain options in the same receiver.  For example, a VR60 receiver
equipped with Options 01, 02, and 03B has an internal power source and is capable of decoding and
displaying data during a monitoring cycle, while storing the data to memory.  Some options are
prerequisites of others, and not all options are compatible with each other.  An option with a lower
number is a prerequisite of a higher numbered option, with the exception of Option 02 and Option
04, which may be included in a VR60 receiver regardless of other options.   A complete list of
option combinations is available in the 

Available Software

 section of this manual.

DECODER/DISPLAY UNIT  (OPTION 01)

The 

Decoder/Display

 unit (Option 01) is installed in the VR60 receiver case with alphanumeric

display and keypad for data entry and control. A serial communications port on the front panel
allows control and data storage by an external general purpose computer, terminal, or printer.

The primary functions of the 

Decoder/Display

 unit (Option 01) are to time the arrival of ultrasonic

pulses, extract any encoded data, and display the information on the LCD display.  The time
between pulses (or period) of a pinger is used for identification and is shown on the display in
milliseconds (ms).  Telemetry transmitters send information, such as temperature, depth, or speed,
by encoding the data in the time between pulses.  A microcomputer within the 

Decoder/Display

 unit

(Option 01) uses manually entered calibration data to process the pulses and extract the encoded
data.   This calibration data is stored in non-volatile memory (see 

Setup Decoder

 section), and is not

lost when the receiver is powered down.  Calibration data may be entered for a maximum of twelve
telemetry transmitters, each with up to two multiplexing data channels.
