Page 18: C - Start Up
C - START UP Assembly Procedure REPARATION Your OCR-504 Multispectral Radiometer is a simple instrument to setup and operate. The instrument may be operated as a stand-alone device or in a networked environment as part of a larger system. Generally, requirements for operation are the same for both of these operating modes, although a networked environment may impose additional requirements. -
Page 19: Connecting The Components
Finally, ensure that the locking sleeve or locking strap is securely fastened after connection. The following is a generic step-by-step procedure for setting up your OCR-504 Multispectral Radiometer. You may use this procedure with any Sea-Bird Scientific approved interface cable: 1. -
Page 20: Network Assembly
The best way to conduct this test is to use SatView with the .sip (Sea-Bird Scientific Instrument Package) file provided with your instrument. A sip file is simply a binary file in zip format that contains a set of calibration and/or telemetry definition files. - Page 21 Otherwise, if you are experiencing any problems receiving telemetry, see section G - MAINTENANCE for information on troubleshooting your instrument. If you are still experiencing problems, contact a Sea-Bird Scientific customer service representative for assistance.

This will continue until power is removed or the instrument is reset. Initialization Sequence Once power is applied to the OCR-504, the instrument begins a four-second window of operation called the initialization sequence. During this time, the on- board electronics are powered up, checked, and readied for operation. If the... -
Page 23: Autonomous Operation
Network operation enabled. Autonomous Operation Autonomous, or stand-alone, operation for the OCR-504 is defined as the continuous operation of the instrument outside the scope of a network. This is the default mode of operation for the instrument. Autonomous operation uses only the telemetry interface for communication and telemetry output. - Page 24 SYSTEM OCR-504 Multispectral Radiometer SECTION D - OPERATION Operation Manual you would use the <Ctrl+C> command to access the command console. To do this, press and hold the Ctrl key followed by the C key. This is the same as sending the hexadecimal equivalent byte “03”...

Page 25: Network Operation
Network Operation Network operation for the OCR-504 is defined as continuous operation of the instrument within the scope of a SatNet™ network. Furthermore, standard network operation means that the instrument is not operating as a Network Master device. -
Page 26: Telemetry Format
D - OPERATION Operation Manual Telemetry Format The telemetry format for the OCR-504, as with all Sea-Bird Scientific instrumentation, follows the Sea-Bird Scientific Data Format Standard. This standard defines how Sea-Bird Scientific telemetry can be generated and interpreted. For every sample taken of the instrument’s sensors, the instrument will compose and transmit one frame of telemetry containing all the relevant sensor information for that sample. -

Page 37: E - Configuration
Terminal emulators are used in many applications involving serial communications, internet mail and news services, telnet and ftp services, etc. For communication with your OCR-504, you will need to make a direct connection to the serial port hosting the instrument. Connect the instrument using the RS-232 telemetry interface. - Page 38 SYSTEM OCR-504 Multispectral Radiometer SECTION E - CONFIGURATION Operation Manual The actual command prompt ends with the “$” character. The characters between the [ ] brackets provide information on the operating mode of the instrument. In the example above, “Auto” indicates that the instrument is running in autonomous mode.

Page 45: Telemetry Baud Rate
SYSTEM OCR-504 Multispectral Radiometer SECTION E - CONFIGURATION Operation Manual The frametype parameter determines the format of the telemetry frame. When modifying this parameter with the “set” command, you must enter “binary”, “short”, or “long” as the value parameter. Please refer to the Telemetry Format section. - Page 46 Providing a maximum frame rate slower than what the instrument is capable of providing will help pace the output of each frame evenly. Generally, an OCR-504 cannot exceed a frame rate faster than 7.5 Hz, even under the best of conditions.
-
Page 47: Initialize Silent Mode
SYSTEM OCR-504 Multispectral Radiometer SECTION E - CONFIGURATION Operation Manual example, 0.5 Hz does not mean that half a frame is transmitted every second. It means that every two seconds, a frame will begin transmitting.

SYSTEM OCR-504 Multispectral Radiometer SECTION E - CONFIGURATION Operation Manual ETWORK netmode Command Line Parameter: This parameter enables or disables network operation for the instrument. Although disabling this parameter will force the instrument to run autonomously, enabling it does not necessarily mean network operation will be invoked. The instrument’s operating mode is determined during the initialization sequence. -
Page 49: Optical Data Averaging Enable
SYSTEM OCR-504 Multispectral Radiometer SECTION E - CONFIGURATION Operation Manual When modifying this parameter with the “set” command, you must enter at least the first two digits of one of these baud rates as the value parameter. IMPORTANT! Make sure that each device on the network, including the Network Master, is operating with the same network baud rate. -
Page 50: Apply Calibration Coefficients Enable
This setting may be useful for synchronizing initial sampling with other instruments, or perhaps for allowing time for an optional Sea-Bird Scientific Bioshutter paddle to move out of the field of view of the OCR-504. The latency value is entered in milliseconds. -
Page 51: Immersion Coefficient
Up to 19 characters may be entered. IMPORTANT! Do not change the calibration coefficients unless you have recalibrated the sensor or instructed to do so by Sea-Bird Scientific personnel. Incorrect calibration coefficients will generate invalid data in telemetry frames generating data using engineering units. -
Page 52: F - Recovery
Operation Manual F - RECOVERY To recover the OCR-504 when it is used in water, terminate data acquisition and pull the instrument back in using the cable. You may then power down the instrument and disconnect all the cables from their corresponding components. -
Page 53: G - Maintenance
If you are experiencing problems receiving data with your data acquisition software, there may be a problem with the instrument, its configuration, or its physical setup. You can check to see if your OCR-504 is transmitting telemetry with a terminal emulator. -
