Page 8 E2 Wireless I/O Chapter 1 – Introduction 1 1.1 Overview The E2 range of I/O modules has been designed to provide standard “off-the-shelf” telemetry functions, for an economic price. Telemetry is the transmission of data or signals over a long distance via radio or twisted-pair wire cable. Although the E2 Series is intended to be simple in its application, it provides many sophisticated features, which will be explained in the following chapters.
E2 Wireless I/O Page 9 Pulse inputs counts are accumulated and the total count is transmitted regularly according to the configured update time. The E2 modules transmit the input/output data using radio or Ethernet. The data frame includes the "address" of the transmitting module and the receiving module, so that each transmitted message is acted on only by the correct receiving unit.
Page 10 E2 Wireless I/O 1.2 Module Structure The E2 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. The I/O Store provides eight different blocks of data - two containing input and output bit data, two containing input and output word data, two containing long-word type data and two containing floating-point data.
E2 Wireless I/O Page 11 There are also a number of Internal I/O that can be accessed from the I/O Data Store. These inputs can be used to interpret the status of a single modules or the entire system • Supply voltage status – If the primary supply fails, this status is set on. • Low battery voltage – Monitors the internal battery charger to trickle charge a back-up battery. If the battery voltage is low, this status is set. • Battery voltage – The actual value of the connected battery voltage.
Page 12 E2 Wireless I/O Chapter 2 – Installation 2 2.1 General All E2 Series modules will be housed in a plastic enclosure with DIN rail mounting, providing options for up to 20 I/O points, and separate power & communications connectors. The enclosure measures 170 x 150 x 33 mm including connectors. The antenna protrudes from the top 2.2 Power/Supply The E2 power supply is of switch-mode design and will accept a 15 - 30 volt DC power source connected to the “Sup + & Sup -” terminals.
E2 Wireless I/O Page 13 The power supply input and battery charging are hosted on a 4-way terminal on the bottom edge of the module labeled “Power Supply”. To allow increased I/O Capacity, a second 4-way terminal labeled “Expansion I/O” provides a +12 Volt supply and RS485 communications for any 115S serial expansion I/O modules.
Page 14 E2 Wireless I/O Meshing capability The ELPRO WIBMesh protocol is based on the “Ad hoc On Demand Distance Vector” (AODV) routing algorithm which is a routing protocol designed for ad hoc networks. AODV is capable of unicast and multicast routing and is an on demand algorithm, meaning that it builds and maintains these routes only as long as they are needed by the source devices. The Protocol creates a table, which shows the connection routes to other device in the system.
E2 Wireless I/O 2.4 Page 15 Antenna The E2 module will operate reliably over large distances. The distance, which may be reliably achieved, will vary with each application - depending on the type and location of antennas, the degree of radio interference, and obstructions (such as hills or trees) to the radio path. Typical reliable distances are detailed below however longer distances can be achieved if antennas are mounted in elevated locations – such as on a hill or on a radio mast.

E2 Wireless I/O Page 17 already shielded from lightning strike by an adjacent earthed structure, a lightning rod may be installed above the antenna to provide shielding. Dipole and Collinear antennas. A collinear antenna transmits the same amount of radio power in all directions - as such they are easy to install and use. The dipole antenna with integral 15 ‘cable does not require any additional coaxial cable; however a cable must be used with the collinear antennas.
Page 18 E2 Wireless I/O antennas should have vertical polarisation, and the common (or “central” station should have a collinear (non-directional) antenna. Also, note that Yagi antennas normally have a drain hole on the folded element - the drain hole should be located on the bottom of the installed antenna. 2.5 Connections Bottom panel connections Ethernet port The E2 modules provides a standard RJ-45 Ethernet port compliant to IEEE 802.3 10/100 BaseT.

This switch should be set to ON to enable the hardware watchdog protection feature. Dipswitch 6 – When set to ON, the module will boot up with a known factory default including a default IP address for Ethernet connection. (Refer to section 4.
Page 22 E2 Wireless I/O Pulsed Inputs The E2 supports 8 digital signals, of which inputs 1-4 can be used as pulsed inputs. The maximum pulse frequency is 50 KHz for Input 1 & 2 and 10 KHz for Input 3 & 4. Digital/Pulsed inputs are suitable for voltage-free contacts, or NPN-transistor switch devices.
E2 Wireless I/O Page 23 Digital Outputs (Pulsed Outputs) Digital outputs are open-collector transistors and are able to switch loads up to 30VDC, 200mA. The 8 digital outputs share the same terminals as the digital input. These terminals are marked DIO1-8. When active, the digital outputs provide a transistor switch to EARTH (Common). To connect a digital output, refer to the diagram across. A bypass diode is recommended to protect against switching surges for inductive loads such as relay coils.
Page 24 E2 Wireless I/O The Failsafe state if ticked (ON) will indicate with the LED being on and briefly flicking off. The Failsafe state if un-ticked (OFF) will indicate with the LED being off and briefly flicking on. Analog Inputs The E2 provides two floating differential analog inputs and two grounded single-ended analog inputs. Analog Input 1 & 2 can be configured to measurement current (0-20 mA) or Voltage (025V). Analog input 3 & 4 can be configured to measure current (0-20mA) or voltage (0-5V).
E2 Wireless I/O Page 25 Single Ended Current Inputs (AIN 3 & 4 only) Single-ended current input mode is useful if the sensor loop is grounded to the E2 module. Devices can be powered externally from the 24V Analog Loop Supply supplied internally within the module. The Dip Switches are used to determine if the inputs will be current or voltage. .
Page 26 Analog Outputs The E2 module provides two 0 - 24 mA DC analog outputs for connecting to instrument indicators for the display of remote analog measurements. The E2 Analog outputs are a sourcing output and should be connected from the analog output terminal through the device or indicator to Common. See diagram for connections.
