    A system can be a complex network or a simple pair of modules. An easy-to-use configuration procedure allows you to specify any output destination for each input. Each 915U-2 radio can have up to 24 expansion I/O modules (ELPRO 115S) connected by RS-485 twisted pair cable. Any input signal at any module may be configured to www.cooperbussmann.com/wirelessresources...

  • Page 9: Module Structure

    1.2 Module Structure The 915U-2 module is made up of different areas that all interface with a central input and output storage area (I/O store). The I/O store is an area of memory made available for the status of the physical on-board I/O and internal I/O registers.

  • Page 10: Getting Started

    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 module by adding an offset to the address. 1.3 Getting Started Most applications for the 915U-2 module require little configuration. The 915U-2 has many sophisticated features, but if you do not require these features you can use this section to configure the units quickly.

  • Page 11: Chapter 2 - Installation

    2.1 General The 915U-2 Series modules are housed in a plastic enclosure with DIN rail mounting, providing options for up to 14 I/O points, and separate power and communications connectors. The enclosure measures 170 x 150 x 33 mm, including the connectors.

  • Page 12: Expansion I/O Supply

    Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual The power supply should be CSA Certified Class 2, approved for normal operation. If the device is being used in a Class I Div 2 explosive area, the supply must have Class I Div 2 approval.

  • Page 13: Internal I/O

    Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual As a guide, when using the I/O power connection from the 915U-2, the number of I/O modules is limited to three 115S-11 (using inputs), or one x 115S-12, or one x 115S-13. If more I/O modules are required, you need to calculate the overall current consumption using the following criteria, and power the modules from an external supply.

  • Page 14: Radio

    The radio operates in the 902–928 MHz ISM band, which is split into two frequency bands, 902–914 MHz (low) and 915–928 MHz (high). In the United States and Canada, the 915U-2 can use both high and low bands. However, in other countries, such as Australia, only the 915–928 MHz band is available.

  • Page 15: Meshing Capability

    See “3.4 WIBMesh” for configuration details. 2.4 Antenna The 915U-2 module operates reliably over large distances. The distance that can be reliably achieved varies with each application and depends on the type and location of antennas, the degree of radio interference, and obstructions to the radio path (such as hills or trees).

  • Page 16: Dipole And Collinear Antennas

    Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual An antenna should be connected to the module via 50-ohm coaxial cable (such as RG58, RG213, or Cellfoil), and terminated with a male SMA coaxial connector. The higher the antenna is mounted, the greater the transmission range.

  • Page 17: Yagi Antennas

    Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual Figure 7 Collinear Antenna Mounting Yagi Antennas Yagi antennas provide high gain in the forward direction, but lower gain in other directions. They may be used to compensate for coaxial cable loss for installations with marginal radio path. The Yagi gain also acts on the receiver, so that adding Yagi antennas at both ends of a link provides a double improvement.

  • Page 18: Connections

    Figure 9 Bottom Panel Connections Ethernet Port The 915U-2 modules provides a standard RJ-45 Ethernet port compliant to IEEE 802.3 10/100BaseT. This port provides full access to the module, including configuration, diagnostics, log file download, and firmware upload of both the local and remote units. Additionally, the Ethernet port can provide network connectivity for locally connected third-party devices with Ethernet functionality.

  • Page 19: Port

    RS-232 Port The 915U-2 module provides an RS-232 serial port that supports operation at data rates up to 230,400 baud. This port supports Modbus protocol. The RS-232 port is provided by an RJ-45 connector wired as a DCE according to the EIA-562 Electrical Standard.

    Digital or Pulsed Inputs Each digital I/O channel on the 915U-2 module 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 but the I/O system will not operate correctly.

  • Page 22: Digital Outputs (Pulsed Outputs)

    Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual Figure 13 Digital/Pulsed Input Wiring Digital inputs 1–4 can be used as pulsed inputs. The maximum pulse frequency is 50 kHz for input 1 and 2, and 1 kHz for input 3 and 4. Digital/pulsed inputs are suitable for TTL signal level, NPN-transistor switch devices, or voltage-free contacts (a relay or switch with debounce capacitor).

  • Page 24: Differential Current Inputs

    Common mode voltage can be up to 27 Vdc. Figure 17 indicates how to connect loop-powered or externally powered devices to the 915U-2 differential analog inputs. It should also be noted that the differential inputs can also be used to connect single-ended current sinking or current sourcing devices.
  • Page 25 Figure 18 AI 1 & 2 Single-ended Current Inputs Single-ended current input mode is useful if the sensor loop is grounded to the 915U-2 module. Devices can be powered from the 24V analog loop supply (ALS) generated internally from the module.

  • Page 26: Voltage Inputs

    Figure 20 Voltage Inputs Analog Outputs The 915U-2 module provides two 0–24 mA DC analog outputs for connecting to analog inputs on equipment (such as PLCs, DCS, and loggers) or connecting to instrument indicators for displaying remote analog measurements. The 915U-2 analog outputs are a sourcing output and should be connected from the analog output terminal through the device or indicator to ground (GND).

  • Page 27: Chapter 3 - Operation

    3.1 Overview The 915U-2 Series I/O modules are designed to provide standard off-the-shelf telemetry functions at an economic price. Telemetry is the transmission of data or signals over a long distance via radio or twisted-pair wire cable. 3.2 LED Indicators When the module is initially connected to power, it performs internal setup and diagnostics checks to determine if it is operating correctly.

    (see “Radio Settings” on page 69). In countries that utilize the full 902–928 MHz bandwidth (such as the United States and Canada) the 915U-2 uses both sub-bands, which makes it possible to force the frequency hopping to the other band (high or low) to avoid radio interference and to separate systems.
