    Telemetry is the transmission of data or signals over a long distance via radio or twisted-pair wire cable. Although the 915U-2 Series is intended to be simple in its application, it provides many sophisticated features, which will be explained in the following chapters.
  • Page 14 The module can easily be switched between the two versions by selecting the appropriate protocol from an inbuilt web page. Each 915U-2 radio can have up to 24 expansion I/O modules (ELPRO 115S) connected by RS485 twisted pair provided there is sufficient power to power all modules with I/O.

  • Page 15: Module Structure

    Ethernet Port Figure 1 – Module Structure The 915U-2 is made up of a number of basic sections, which all interface with a central Input and output storage area (I/O Store). The I/O Data Store provides storage for I/O data as well as providing services to other processes in the system.

    • Comms Fail – A selectable register can indicate a Communications fail for a particular message transmission. The Expansion port, allows 115S expansion I/O modules to be added to the module. Expansion I/O is dynamically added to the internal I/O of the 915U-2 by adding an offset to the address. 1.3 Getting Started Most applications for the 915U-2 require little configuration.

  • Page 21: Radio

    The radio operates in the 902-928 MHz ISM band which is split into two sub-bands, 902-914 MHz (Low) and 915–928 MHz (High). In America and Canada, the 915U-2 uses both high and low sub-bands - however in other countries, i.e. Australia only the 915-928MHz band is available (Some countries use fewer channels, e.g.

  • Page 22: Antenna

    Page 21 2.4 Antenna The 915U-2 module will operate reliably over large distances. The distance that can be reliably achieved will vary with each application and depend on the type and location of antennas, the degree of radio interference, and obstructions (such as hills or trees) to the radio path.

  • Page 23: Figure 6 -Wrapping Coax Connections

    Page 22 915U-2 Wireless I/O The net gain of the antenna/cable configuration is determined by adding the antenna gain and the cable loss. For example, a 6 element Yagi with 70 feet (20 metres) of Cellfoil cable has a net gain of 4dB (10dB – 6dB).

  • Page 24: Dipole And Collinear Antennas

    915U-2 Wireless I/O Page 23 We recommend that the connection be taped, firstly with a layer of PVC Tape, then with a vulcanising tape such as “3M 23 tape”, and finally with another layer of PVC UV Stabilised insulating tape. The first layer of tape allows the joint to be easily inspected when trouble shooting as the vulcanising seal can be easily removed.

  • Page 25: Yagi Antennas

    Page 24 915U-2 Wireless I/O Yagi antennas. A Yagi antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to compensate for coaxial cable loss for installations with marginal radio path. The Yagi gain also acts on the receiver, so adding Yagi antennas at both ends of a link provides a double improvement.

    915U-2 Wireless I/O Page 29 2.5.3 Digital Inputs Each digital I/O channel on the 915U-2 can act as either an input or an output. The input/output direction is automatically determined by the connections and configuration of the I/O. If you have an I/O channel wired as an input but operate the channel as an output. No electrical damage will occur however, the I/O system will not operate correctly.

    915U-2 Wireless I/O 2.5.4 Pulsed Inputs The 915U-2 supports 8 x digital signals, of which inputs 1 to 4 can be used as pulsed inputs. The maximum pulse frequency is 50 KHz for Input 1 & 2 and 1 KHz for Input 3 & 4.

    The digital channels DIO1-4 on the 915U-2 module can be used as pulse outputs with a maximum output frequency of 1 KHz. Digital Output Fail Safe Status As well as indicating the Digital Output status (on / off), the LEDs can also indicate a communications failure by flashing the Output LED.
