Overview

The i-300 Mediator IP Gateway provides a comprehensive built-in I/O capability allowing remote management of digital, analog, serial, and power cycled devices. The i-300 has in-built interfaces and may extend its I/O capability through the connection of various Willhart external I/O modules.

The Mediator's internal SNMP agent represents the devices in the Mediator Management Information Base (MIB). This MIB is dynamically configured allowing the integration of any device which has the capability to interface to the physical Mediator I/O Modules.

Digital Interfaces

Digital Interfaces are used to connect to devices with interfaces which are either ON or OFF. Examples of such interfaces include voltage free contacts on alarm systems, smoke detectors or air-conditioning systems.

The Mediator Digital Interface provides six digital inputs and two relay outputs. External RS485 I/O Modules are available in fourteen digital input (DM1400) and seven digital output (DM07) models.

Using the Mediator RS485 Expansion Bus, a number of External I/O Modules can be incorporated allowing multiple digital interfaces.

Analog Interfaces

Analog Interfaces are used to connect to devices such as Temperature and Humidity Sensors. The MediatorAnalog Interface provides four analog inputs and on analog output. Willhart AM80 external RS485 I/O Modules provide eight analog inputs each. Using the Mediator RS485 Expansion Bus, multiple External I/O Modules can be incorporated allowing a large number of analog interfaces.

Serial Interfaces

Serial Interfaces are used to connect to devices that communicate using character streams. Examples of such devices include PABXs/PBXs and UPSs. These devices send out strings of characters in response to alarm conditions. The Mediator actively monitors these character streams and sends corresponding alarms to the Network Management Station.

Furthermore, the Mediator Agent supports the Telnet protocol, allowing the user to remotely login to the devices connected via the serial ports. This allows remote diagnostics and configuration of equipment such as PABXs. The Mediator is equipped with four serial ports for connection to serial devices.

Power Cycling Interfaces

The Power Cycling Interfaces provide the functionality to cycle power to locked up network devices (turn the power off and on). An added benefit is that devices that do not need to be on all the time can be scheduled to turn on and off when required, thus saving power.

The i-300 Mediator allows the connection of external Power Cycling Units (PCUs). Each PCU4 has four IEC power outlets and can independently switch power to any outlet. Up to eight PCU4s can be connected to the i-300 Mediator via the Expansion Bus allowing a maximum of 32 devices to be controlled.

Functional Summary

The Mediator can fully support Windows NT and UNIX SNMP Platforms including: CA Unicenter TNG; Solstice SunNet Manager; HP OpenView; Cabletron Spectrum and IBM Tivoli TME 10.

Network Interfaces

  • Ethernet 10Base-T

specifications

The Mediator i-300 provides in-built I/O for remote management of digital, analog, serial devices, and may further extend I/O through connection of external modules.

The Mediator's internal SNMP agent represents devices in the Mediator Management Information Base (MIB), which dynamically configures to integrate any device physically connected to the Mediator.

Digital Interfaces

The Mediator Digital Interface provides six digital inputs and two relay outputs to connect devices whose state are either ON or OFF, such as voltage free contacts on alarm systems, smoke detectors or air-conditioning systems. The inputs are optically-isolated 24VDC contact sensing inputs.

Digital Input Specifications

  • Channels: 6 isolated Digital inputs
  • Contact Ratings: 24VDC @ 5 mA
  • Switch levels:
    • ON - 24V nominal (10V to 35V)
    • OFF - 0V nominal (0V to 4V)
  • Isolation voltage: 5 kV
  • Reverse polarity protection
  • 3.5mm pitch screw terminal, 28 - 16 AWG wire

The digital outputs are voltage-free contacts, each providing either normally-open or normally-closed terminals.

Analog Interface

Analog Interfaces are used to connect to devices such as Temperature and Humidity Sensors. The Mediator Analog Interface provides four analog inputs and one analog output. Each analog input has a 4-way terminal block, enabling scaling resistors to be connected. Both variable current and variable voltage sensors may be connected.

Analog Input Specifications

  • VIN 0 to 5 VDC
  • Maximum Input Current: 100 nA

The Analog Output has a 2-way terminal block.
