  • Page 14: Using This Manual

    There are twelve chapters in this manual. These twelve chapters introduce you to the 8310 and present the basics to get you started using the 8310. Chapters 1 through 3 should be read by anyone planning to use the 8310. Chapter 4 contains a detailed reference of all the 8310 menus and commands.

  • Page 15: Chapter 1: Introduction

    This chapter introduces you to the Sutron Model 8310 & 7310 family of data recorders and transmitters and presents the features and capabilities that make the 8310 & 7310 the ideal product to use for a remote environmental monitoring system.

  • Page 16: 8310 & 7310 Overview

    For even more durability, each 8310 is tested to operate over the -40 C to +60 C temperature extremes expected in remote environments. Full EMI and transient protection are built into each input.

  • Page 17: 7310 Features

    4/16/2014 7310 Features The 7310 runs the same software as the 8310, but has a subset of the features of the 8310. It includes all the features of the 8310 with these exceptions: Only one serial telemetry device, com 2...

    SD card -- setups can be stored on the SD Memory Cards. To copy a setup to the 8310 simply, plug the SD card into the memory slot and issue the copy setup command. It takes only a few seconds for the 8310 to copy the setup from the card to its memory.

  • Page 19: Sealed Enclosure

    Large Secure Memory The 8310 has built-in flash memory capable of storing the station setup and configuration data along with memory to “log” (or record) over 1,000,000 data points. This memory doesn’t use a battery and, as a result, it is always preserved even when power is lost or interrupted to the 8310.

  • Page 20: Chapter 2: Unpacking And Initialization

    Initialization This chapter provides information to help you unpack the 8310 and start using it. You will learn how to hook a battery to an 8310 and how to run a quick test to make sure it is operating properly.

  • Page 21: Unpacking

    Connecting the Main Battery The 8310 runs off 9 to 18VDC with a peak power requirement of 1 amp (not provided). Connect a suitable power source to the 8310 as shown below. When power is applied, the unit will automatically startup and if configured, begin operations.

  • Page 22: Quick Test

    You can also tell the 8310 is running by watching the Status LED. In normal operations, the green LED will flash periodically as the 8310 operates. If the green LED is not flashing or if the red LED is on, the 8310 may not be operating properly.

  • Page 23: Chapter 3: Getting To Know The 8310

    This chapter describes in detail the 8310 front panel (including connections, controls and displays) and the menus that you will use to set up and operate the 8310. Complete information is given on how to operate the 8310 from the front panel or a PC.

    “Flash Disk>,” type the command UI and press ENTER. If the 8310 still does not display the main menu, you must use the front panel of the 8310 to verify that COM1 is configured as DIRECT and that the baud rate is set to 115,200. To do this, go to Station Setup/Communications/COM1 and verify that the state is STARTED and DIRECT.

  • Page 42: Selecting Options And Changing Values

    8800-1125Rev. 2.7 (BETA) 4/16/2014 If you will remember, when using the front panel display to set up the 8310 you were required to push the directional arrows to move around the menu tree. When using a PC, you may also use the arrow keys or press the first letter in any item in order to move around the menu.

  • Page 177 Let Calibrate Compute the Slope and Offset for you The 8310 calibrate function built into the 8310 can compute the slope and offset for you. In order to use the calibration function, you will need to have an independent measurement for the input or a way to force the input to a known value.
  • Page 178 Understand Alarms and Alarm Transmissions The 8310 can be set up to detect alarms on sensor values and to make transmissions as a result of an alarm. This section describes alarm detection and notification in detail. Anyone using alarms should make sure they understand the concepts presented here.
  • Page 179 Store and forward and cross device repeating SSP messages The 8310 can store and forward SSP messages either back out the same port (“smart repeating” or out another port (“cross device repeating”. Smart repeating is used in LOS radio systems to send a message to a site which is on the fringe of reception or out of range by using a third site in the middle.

  • Page 186 The 8310 uses different amounts of power depending on what it is doing. The only way to come up with the power budget is to determine how much time the 8310 spends in each of its tasks and how much power is used doing each task. The following list shows the power used by the 8310 in some typical tasks.
  • Page 187 Note that the internal charger in the 8310 has been designed to handle up to a 20W solar panel. If a larger panel is needed to handle the station load, then an external regulator should be utilized.
  • Page 188 There is a ground lug located on the lower left hand corner of the 8310 which can be used to connect to. When bringing the wire into the gage house or Nema Enclosure, try to keep bends in the wire to a minimum since lightning tends to follow a straight pathway.
  • Page 189 Fill out and use the 8310 setup sheet. As stated in Section 5, the setup sheet is the tool used to specify the details of the 8310 setup. The best place to create the setup sheet is on the bench with as many of the sensors connected to the 8310 as possible.

  • Page 192 4/16/2014 Introduction There are many ways to retrieve data from the 8310. This chapter presents all the ways that we know of. You may be able to figure out a few of your own. There are two basic types of readings that the 8310 can communicate: last measured value and logged data.
  • Page 193 You should normally wire pin 4 of the 8310 to the Carrier Detect (CD) line of the RF modem being used. The RF modem must bring pin 4 high when carrier is detected. Incoming messages are treated as terminal input.
  • Page 194 4/16/2014 GOES Data When you have an 8310 with a GOES module, the data can be transmitted over GOES on a self- timed schedule, random/alarm schedule or both. You have complete control over what data is included in each type of transmission and how much data is sent. You also have partial control over the transmission format.
  • Page 195 Chapter 10: BASIC BASIC is a programming language built into the 8310. You can use it to add special equations and processing to sensor data, do different alarm detection and much more. BASIC makes the 8310 flexible to handle custom applications, yet easy to use.
  • Page 196 Up until this point in the user manual, you have learned about some of the simpler operating procedures behind the 8310. One of its more powerful yet more complicated functions remains to be covered. This chapter will attempt to explain, in some detail, the BASIC interpreter that has been added to the 8310.
