    RF400 Series Spread Spectrum Data Radio/Modems Auto Sense The RF400 has a default feature called “Auto Sense” that automatically configures certain RF400 settings. When you connect an RF400 to a datalogger (CS I/O port to CS I/O port) the RF400 detects the presence of the datalogger and makes its CS I/O port the active port.

    RF400 Series Spread Spectrum Data Radio/Modems Green LED activity indicates that there is an RF signal being received whose hopping sequence corresponds to the configured hopping sequence of the RF400. This does not necessarily mean that the network/radio address of the received packet corresponds with that of the RF400 (where a neighboring network exists it is a good idea to choose a unique hopping sequence).

    RF400 Series Spread Spectrum Data Radio/Modems For example, if you input a value of 50, then packets with hop sync info will be sent out every 5 seconds improving (shortening) the response time of a transmit/response sequence. Even though this shortens the time required to send x amount of data, the throughput is still determined by the CS I/O or RS-232 port baud rate setting.

  • Page 31: Remote Station Setup

    RF400 Series Spread Spectrum Data Radio/Modems Select a Radio Address (0 – 1023). The radio addresses must be the same in point-to-point communications (for point-to-multipoint communications you could set the base RF400 to 0 and the remotes to 1, 2, 3, etc.). It is a good idea to label each RF400 indicating the configured network address, radio address, hopping sequence, etc.
  • Page 32 RF400 Series Spread Spectrum Data Radio/Modems Point-to-multipoint Complete steps 1 to 4 above making the remote stations’ Network Addresses and Hopping Sequences the same as the base station’s. While in Standard Setup verify that the active interface is “Auto Sense” and give each remote RF400 a unique Radio Address. You should label each RF400 (with masking tape) indicating the configured network address, radio address, hopping sequence, etc.

Troubleshooting If you can’t connect, check out these possible causes: Datalogger or Wiring Panel lacks 12 V power on pin 8 of CS I/O port The RF400 should go through its initialization with red and green LEDs lighting (see Section 4.1.1) when serial cable is connected if 12 V is present on CS I/O connector (see Quick Start Table 1).
  • Page 37 RF400 Series Spread Spectrum Data Radio/Modems RF400 receiver “de-sensing” from nearby transmitter This problem can be observed from LED behavior when operating a hand- held radio near an RF400 that is receiving collected data from a remote station. If you key a hand-held 150 MHz or 450 MHz transmitter, even though its frequency of operation is far removed from the 900 MHz band, its close proximity to the base RF400 can overwhelm (de-sense) the RF400 receiver resulting in failed packets and LoggerNet/PC208W...

If this appears likely, exit PC208W and copy and paste your backup file over the suspect .dnd file to restore proper operation.

Short-Haul Modems With short-haul modems it is necessary to configure the base NOTE station RF400’s “RS-232 Auto Power Down Enable” (in the Advanced Setup \ Interface Parameters menu) to mode "0" which will maintain the radio's RS-232 port always active. This results in an additional constant 2 mA current drain by the RF400.

  • Page 58 Appendix H. Distance vs. Antenna Gain, Terrain, and Other Factors How Far Can You Go? Distance Estimates for Spread Spectrum Radios Overview There is a great deal of interest in estimating the distance you can expect to achieve with the RF400 radios. Also of interest are the effects of cable length, antenna gain, and terrain.
  • Page 59 Appendix H. Distance vs. Antenna Gain, Terrain, and Other Factors Pr => signal power at the radio receiver in dBm The signal power at the receiver (Pr) must exceed the receiver sensitivity (−110 or –104 dBm) by a minimum of 6 dB for an effective link. The amount that Pr exceeds –110 dBm or –104 dBm (2.4 GHz) is the link margin.

    Appendix H. Distance vs. Antenna Gain, Terrain, and Other Factors Antenna Gain Antenna gain is specified either in dBi (decibels of gain relative to an isotropic radiator) or in dBd (decibels of gain relative to a dipole). The relationship is: dBi = dBd + 2.15 Some antennas that are FCC approved for use with the RF400 series are: Mfg.

  • Page 82 Appendix L. RF400/RF410 Average Current Drain Calculations EXAMPLE #2 (Base RF400/RF410 in default standby mode) The base RF400/RF410 in the above example does more receiving and less transmitting than the remote RF400/RF410 so you might expect less average current drain, however, the amount of data being transmitted per minute is small, and the long header required is significant.
  • Page 83 Appendix L. RF400/RF410 Average Current Drain Calculations EXAMPLE #3 (Base RF400/RF410 in “<0.4 mA, 8 sec Delay” standby mode) The RF400/RF410s in this example are configured for the lowest possible average standby mode current (Advanced Setup Menu selection 7). The same amount and frequency of data are collected as in Example 1.
  • Page 84 Appendix L. RF400/RF410 Average Current Drain Calculations EXAMPLE #4 (Remote RF400/RF410 in “<0.4 mA, 8 sec Delay” standby mode) The RF400/RF410s in this example are configured for the lowest possible average standby mode current (Advanced Setup Menu selection 7). The same amount and frequency of data are collected as in Example 1.
  • Page 85 Appendix L. RF400/RF410 Average Current Drain Calculations EXAMPLE #5 (Base RF400/RF410 in default “<4 mA, 1 sec Delay” standby mode) The RF400/RF410s in this example are configured for the default average standby mode current. The same amount of data (10 data points) are collected as in Example 1, however the frequency of collection is changed from once a minute to once an hour.
  • Page 86 Appendix L. RF400/RF410 Average Current Drain Calculations EXAMPLE #6 (Base RF400/RF410 in “<0.4 mA, 8 sec Delay” standby mode) The RF400/RF410s in this example are configured for the lowest possible average standby mode current (Advanced Setup Menu selection 7). The same amount of data are collected as in Example 1, however the frequency of collection is changed from once a minute to once an hour.
  • Page 87 Appendix L. RF400/RF410 Average Current Drain Calculations EXAMPLE #7 (Remote RF400/RF410 in “<0.4 mA, 4 sec Cycle” standby mode ) The RF400/RF410s in this example are configured for the lowest possible average standby mode current (Advanced Setup Menu selection 7). The same amount of data are collected as in Example 1, however the frequency of collection is extended to once an hour.
