Introduction

locations is not practical, the TIM may be used to monitor the MLK remotely and provide

notification of these MLK events. This minimizes the need for travel to very remote sites.

The TIM connects to the MLK using a serial interface. The TIM also connects to an SNMP host

to deliver the events detected within the MLK. When connected, the TIM continuously polls the

MLK for its current log file and examines the file for new, reportable events.

Using a Microsoft Excel spreadsheet tool to establish which events should be detected, and under

what conditions, enabled events are uniquely translated to an “SNMP Trap” protocol and sent to

the host application over an IP-based Wide Area Network (WAN) connection.

Because the TIM maintains a continuous connection to the host application, a facility is provided

that allows distant maintainers and technicians to remotely invoke many of the M

ICROLOK II

Development System functions over the network, further minimizing the need to visit remote

sites when researching or remedying a MLK related system anomaly.

2.2. Feature Overview

The top panel of the TIM contains a backlit LCD display unit, six local menu navigation buttons,

and four LED status indicators. The front panel of the TIM contains two Ethernet ports, one

USB port, two serial ports, and one DC power input connector. See

Figure 2-1.

2.2.1. Top Panel Features

The top panel LCD display shows current IP address information for the TIM WAN and SNMP

host connections. The local menu navigation buttons are not used in this TIM application. All

active TIM features are accessed remotely using a WAN connection with the SNMP host or

locally using a laptop computer connected to the TIM front panel.

Only two of the four bi-color (red/green) LED indicators are used in this TIM application:

Communication Status and System Status. The TIM tests all four LEDs during powerup

(solid red and solid green), then controls the active LEDs in this TIM application.

2.2.2. Front Panel Features

The front panel Ethernet RJ-45 connectors allow connecting the TIM to a WAN and laptop

computer. ETH0 is typically used for connecting a laptop computer for configuring the unit.

ETH1 is typically used for connecting the unit to a WAN for data communication. Serial Port 2

is used for data communication with the MLK; Serial Port 1 is not used in this TIM application.

The 8–30VDC connector receives TIM operating power from the site power distribution system.

The remaining connectors on the front panel are not used in this application.
