GTRM 100 Installation Guide Overview The GTRM 100 was designed to provide an easy and convenient way to remotely monitor ground cabling and components at site locations prone to copper theft. The GTRM 100 contains everything you need to activate alarms and automatically send alert messages via email or SNMP. Providing you with instant feedback the moment a copper line is cut or a ground bar has been removed that is being monitored by one of the 5 ground monitoring channels on the GTRM.
GTRM 100 Overview Use the Diagram below to familiarize yourself with the GTRM components and features.
GTRM Installation Because the GTRM can be used in a variety of applications there are many variations on exactly how the GTRM can be installed and connected to ground lines. Please use the steps below as a guideline for installing the GTRM. Proper testing should be done after installation to ensure you receive the desired level of alarming and alert messages.
Installation Steps Step 1: Mounting the GTRM Mount the GTRM in a suitable location inside the shelter or cabinet. The GTRM mounts easily to any flat surface. The mounting flanges can be used to mount to wall or board, two-sided tape or Velcro can also be used to secure the GTRM. The mounting location should be in close proximity to the exit point of the ground wires that you wish to monitor. Step 2: Choose the Connection points to monitor and then Run the Wiring.
Using a Terminal Block: The #6 wiring will then be reduced to 18 AWG wire inside the cabinet or shelter by using a standard terminal block. The 18AWG will then connect to the GTRM channel block. Connecting the Comm Terminal: The Common wire from the GTRM is connected to the main ground bar inside the shelter or cabinet. The common wire must be connected or the GTRM will not function properly. Step 3: Connect Power to the GTRM The GTRM comes in both AC and DC versions.
Step 4: Make Final Connections To GTRM Choose your method of alarming and make Ethernet and Dry Contact connections as necessary. Ethernet Connection will require you to configure IP Network Settings and Email parameters. SNMP trap messages and network configurations will be necessary if using GTRM SNMP functionality for alarming. Coordination with your network administrator will be necessary to configure SNMP alarming on the GTRM.
If using email alerts, confirm receipt of alarm notification email when GTRM goes into alarm. This will verify your network and email configurations are correct. Verify SNMP setup and receipt of correct SNMP messages when GTRM goes into Alarm Confirm dry contact configuration and wiring is setup correctly when GTRM goes into alarm. If using the dry contacts to wire into an existing alarm monitoring system, verify that the alarm company is seeing the alarm notification.
The Toroid Ground Sensor The Ground sensor uses a clip-on toroid to detect low level currents on the ground wire that generate a magnetic field inside the toroid. The Toroid converts this magnetic field to electrical current and passes it on to the GTRM. If the magnetic field is no longer present, (ground is lost), the current to the GTRM is interrupted causing the GTRM to go into alarm. When the Toroid Sensor is in alarm, the indication will be displayed through Alarm 2 on the GTRM.
Push Button Configuration: To activate or deactivate channels 1. Press PB3 for 3 seconds to enter setup mode. 2. When All LEDs briefly flash, press PB1 to step through channels 3. Press PB2 to toggle channel on/off a. GREEN LED = channel ON b. RED LED = channel OFF 4. Press PB3 to exit setup and save configuration For Factory Reset 1. Hold PB1 down for 15 to 20 seconds until all LEDs blink, then release button. Webpage Configuration – Use your web browser to connect to the GTRM.
3. Verify Your Network settings and Connection to the GTRM – You can ping the GTRM to verify connectivity. For Direct GTRM to PC Connection For the initial configuration of the GTRM and to change Network setting IP settings for placement in an IP based network you will need to connect the GTRM directly to your PC. Once connected to your PC you will be able to configure the GTRM to match your network settings.
2. In the window type cmd and click OK 3. Type ipconfig then 4.
5. Verify connectivity to the GTRM by sending a Ping command to the GTRM’s default IP address: PING 192.168.1.214 you should receive four REPLY messages from the GTRM. 6. Open a New Web Browser Session (Internet Explorer, Firefox or Google Chrome) and type in the address of the GTRM (default is 192.168.1.214) and click go or .
correctly you should see the System Status of the GTRM. Note: The Status light blinks when the GTRM is active. GTRM Web Interface Menus The GTRM will need to be configured to match your network settings as well as your email and SNMP notification if those features are to be used. The following Screenshots will explain the different menus of the GTRM user interface. This interface allows you to remotely configure and change settings across the network.
This screen displays an overview of the channel status on the GTRM. You can quickly see any alarms occur by watching this screen. You can show the alarms on this screen by removing any one of the three ground leads to cause an alert on the GTRM.
This screen walks your through the channel setup. You can turn on or off any of the channels at anytime. If you only want to monitor two or three channels then turn those channels on while the others remain off.
The options screen provide you access to the Alarm contacts. You can toggle between normally open or normally closed contacts. You can set the Alarm contacts up independently of each other enabling you many possiblities for external alarm notifications. UPDATE: The Options screw now contains a check box to enable the Ground Sensor.
The email configuration screen is where you setup the contact information of the person you want to alert when the GTRM goes into alarm. Contact: Enter the name of the contact person responsible for the site. Location: Enter a short description of the site location the GTRM is monitoring The following information should be obtained from your Network Administrator to setup the SMTP server.
When you have everything set up correctly, use the Email Test screen to send a test email to your account. This will verify the settings. Note: You must have a direct connection to the Internet in order for the email alerts to work. If you are connected to a corporate network or behind a firewall the email alert may not work. A network administrator will need to configure the GTRM to be part of the network and give it access to the Internet to ensure the email configuration works properly.
This screen allows you to configure the Network settings on the GTRM. DO NOT change any of the settings here unless you know what you are doing. These settings should be configured under the direction of your network administrator. Multiple GTRM’s could be active in the network at the same time. Each will have its own IP address to allow for remote access and monitoring. To access any GTRM in the network, open a web browser and type the IP address of the GTRM into the address bar.
This screen provides access to the SNMP settings. If you wish to use SNMP alerts the Read and Write strings will need to be configured to match your network. These settings should only be changed by a Network Administrator or by someone who understands the proper settings for your network. NOTE: SNMP configurations may be confusing. Please consult your Network Administrator to assist you in the SNMP configuration and setup.
The Help screen provides you with the Default settings for the GTRM and instructions on how to configure the major options on the GTRM. It explains in detail how to manually configure the GTRM using the configuration buttons on the top of the unit.
The About and Factory Screens provide you with software version information and provide access to restore the GTRM to factory defaults.
SNMP Functionality In order to accept SNMP messages being sent from the GTRM you will need to have an SNMP monitoring system in your network or a MIB browser loaded onto your laptop. Network SNMP Monitoring For Network SNMP functionality, consult your network administrator for SNMP setup and configuration parameters and how the GTRM should be configured for your specific SNMP requirements and trap receivers.
Once the MIB browser is loaded, click on the desktop icon to launch it. You will see the main screen that should look similar to the one below. In the Address field type in the IP address of the GTRM. 192.168.1.214 also, expand the folders on the left menu and highlight private.
You should see data results begin to fill up in the main window Results Tab 28
Configure the Trap Receiver In order to receive SNMP Traps (alert messages) you will need to setup your MIB browser to receive them. This means you need to setup your TrapReceiver so that the GTRM knows where to send the traps. So in the next you will setup the TrapReceiver IP address. (You will set this to the IP address of your laptop that you recorded earlier) In the Results Table locate the line that says trapReceiverAddress.
Enter the IP Address of your PC or Laptop in the Value field and click OK Note: In order to receive SNMP messages the GTRM and the associated PC or Laptop must be on the same network or be able to communicate across networks. Verify connectivity by pinging the GTRM with your PC or laptop. If you receive a reply you should be able to receive SNMP messages. If your entry was successful you will see a SET succeeded window.
Steps to shut down Application binding to Port 162 1. Load CurrPorts software – find the cports.exe file on the thumb drive and load it onto your computer. 2. Click on the cports.exe icon to launch the software 3.
4. Locate the application that is using port 162 by finding it under the Local Port column. Click on the line to highlight it. 5.
6. Select Yes on the window that asks if you want to kill the process. 7. You should now be able to return to the MIB browser and continue to open the Trap Receiver. Open Trap Receiver In order to see the SNMP alert messages coming in you will need to open the trap receiver Tab. To do this, in the MIB Browser, go to Tools and select Trap Receiver.
You should now see a Trap Receiver Tab in the main window of the MIB Browser. Now, in order to see the SNMP traps coming in you need to throw the GTRM into an alarm by removing one ground lead at a time. As you remove the first ground lead you should see the GTRM alarm LEDs go red and the amber LED light illuminate on the Demo kit. In a few seconds you should see an SNMP message alert come into the trap receiver in the MIB Browser.
When you remove a second ground lead you should see the second alarm on the GTRM, the RED LED illuminate and you should receive the second SNMP message come into the MIB Browser. ALSO NOTE: along with the LED alarms, the software alarms in the GTRM user interface and the SNMP alert messages, the GTRM is also sending out email message alerts to the email address that you configured in the email setup section.
