概览

RF500M 是一款具有多种功能的电台modem,用于带UHF/VHF电台的网络。它可以充当野外modem连接到数据采集器,或者充当基站modem连接到计算机。RF500M可以搭配使用我们的RF320系列电台、RF310系列电台、RF300系列电台,或通过RS-232输出调制字节流的任意电台和modem的组合。

优势与特点

  • Supports multiple radio configurations
  • Uses software (DevConfig) instead of hardware modifications to upgrade the operating system (OS) and change RF ID or other settings
  • Provides an RS-232 port (DTE) for modem configuration or attachment of an RS-232 radio
  • Avoids all collisions within a network, thus increasing polling speeds and reducing overall current drain

图像

Our RF networks require line-of-sight transmission. The mountain in this drawing obstructs line-of-sight with the base station. Use of the repeater station allows the base station to  receive data from the field stations.
The RF500M is used as a stand-alone repeater to provide a communication relay between stations that cannot communicate directly due to distance or obstacles.
At the field station, the RF500M modem functions as a communication interface between the datalogger and radio.

技术说明

RF500M 充当远程的转发器,和基站通讯接口,一般用在我们的经许可的电台应用中。它提供在数据采集器/计算机和电台之间的一个接口,和一个电台,可以用作独立工作的转换器,当现场记录不需要的时候。RF500M 由CS I/O 端口或由外部的电源连接来供电。这种modem可软件设置,已经设计接口支持数据通讯电台,诸如我们的RF320系列、RF310系列和RF300系列 VHF/UHF 电台。

-PB 操作系统

RF500M的 -PB 操作系统设计用来快速而高效地通过网络转移数据,因而它是大型网络或要求快速收集间隔的网络的完美选择。

网络的分时问询传输(TD-RF)属性提供了无冲突通讯,因为基站modem控制所有数据何时转移和如何转移。一个广泛区域的问询释放源自站点的数据,每一个站点都有自己的动态被分配的通道,用来数据传输。数据被下载,并通过网络传回到基站。双向通讯允许每一个站点都可以被远程地从基站来管理(发送程序、改变变量等)。通过使用PakBus协议,站点与站点之间的通讯也是可能的;不过,通讯通过问询发生,而且必须通过LoggerNet服务器来分配路径。

-DA 操作系统

-DA 操作系统使得从网络中的任何位置任何时间,都能对每一个站点拨号。这种能力支持无主控的点对点通讯。

-AL 操作系统

ALERT(实时的自动本地评估)操作系统允许发送、转发和接收二进制的ALERT格式数据。另外,它是-PB 操作系统的洐生版本,因此可既支持ALERT,也支持TDRF通讯(允许与站点的真实双向通讯)。

当用作ALERT发射器时,RF500M接受一批ALERT ID/值 的数据对,允许多数据包发射。它还可以将任何一个站点转变成带可编程的通过/拒绝列表的存储并转发ALERT 转发器。通过这种能力来发射、接收、解码和转发ALERT 数据,RF500M和数据采集器允许创建标准的和高级的ALERT 网络组件,包括:

  • 发射器
  • 带传感器输入的转发器
  • 储存并转发的转发器
  • 多频段转发器
  • 数据集中器
  • 功能强健的大流量基站

Data Logger Considerations

Time division polling and PakBus communications can be used in the same network as long as all of the data loggers are PakBus versions.

Notes:
#The RF500M cannot be a repeater while the modem is connected to a CR200(X) or CR300-series datalogger.
**The RF500M is only compatible with the CR6 when using -PB OS version 3 or later.
The -PB OS option for the RF500M is only compatible with the -PB and -TD OS for the CR510, CR10X, and CR23X.
The -DA OS option for the RF500M is NOT compatible with the -TD OS option for the CR510, CR10X, and CR23X.

Radios

Three jumper settings allow the RF500M to be used with a variety of radios. Though not a requirement, it is a good idea to standardize your network to use a single radio type. This practice simplifies operations and maintenance and provides the highest degree of interstation compatibility possible.

Note:
The RF500M must have the -PB OS option to use a digital RS-232 radio with it.

Radio Modems and Radio Base Stations

Networks can contain a mixture of RF500M modems and other Campbell Scientific radio modems and base stations assuming they have compatible operating systems (see chart below).

常见问题解答

RF500M: 7

展开全部收起全部

  1. Yes. When the RF500M is powered up (or whenever the internal processor is reset), each of the LED indicators on the modem will illuminate, cycle through a series of colors, and turn off. This is an indication that the RF500M is running the Power On Self-Test (POST). If the LEDs remain illuminated, this is an indication that the POST has failed.
  2. Usually, yes. Contact Campbell Scientific for a return material authorization number (RMA) and instructions for returning the unit for repair. Additional information is available on the Repair and Calibration page.

  3. The RF500M Radio Modem is warranted by Campbell Scientific, Inc., to be free from defects in materials and workmanship under normal use and service for twelve (12) months from date of shipment unless specified otherwise.
  4. Engineering drawings, in general, are not made accessible to the public. For a specific question, contact Campbell Scientific for assistance.

  5. No. The RF500M cannot be directly interfaced with a GPS receiver. However, most Campbell Scientific data loggers can be interfaced with the output from a GPS receiver and programmed to extract the positional information. This information can then be accessed via an RF500M/RF320 RF link.

  6. No. The CR1000KD is designed specifically for use on the CS I/O port of the CR800, CR1000, and CR6 dataloggers. 

  7. If the RF modem has a CS I/O connector, then it should be compatible with the CR10X without the use of an SC932A. Ensure that the RF modem’s firmware is compatible with the CR10X firmware.

    Note: RF modems that are not sold by Campbell Scientific will only interface with a CR10X via an SC932A or an SC105.
