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.
