Setting up a Local Network Connection using Static IP or DHCP

Static IP Set Up:

Connect an Ethernet Cable between the PC and the communications board labeled S2A-389S. Open the Control Panel through the Windows start menu. In Control Panel double click “Network Connections”. In network connections, right click “Local Area Connection” and select “Status” from the drop-down menu.

From Local Area Connection Status window, select “Properties” in the bottom left corner. From the properties menu, select “Internet Protocol Version 4 (TCP/IPv4)” and click Properties.

From this new window, enter the desired IP address (192.168.0.15 in the example below) other than the system IP address i.e. 192.168.0.6 and Subnet mask to “255.255.255.0”. Click “Ok” to save the settings and exit out.

Open Internet Explorer (or any other browser) and enter the IP Address/Host Name of the system 192.168.0.6/ or http://LMCBOARD in the address bar. The La Marche A12B website will be loaded similar to the one below. The default username is “admin” and password is “lamarche”.

Simple Network Management Protocol Version 3 (SNMP)

Simple Network Management Protocol (SNMP) is a network protocol designed to manage devices over an IP network. “It was defined by the Internet Architecture Board (IAB) in RFC1157 for exchanging management information between network devices. It is a part of Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite.

SNMP consists of four major components:

1. SNMP Manager
2. An Agent
3. Managed Devices
4. Management Information Databases

SNMP Manager is installed on a computer that already has management software. This management console simply monitors, responds and manages any query that is being sent from the Agent. It will decide whether it needs to send email notifications or ignore them. This is a computer that is used to run one or more network management systems.

An Agent is a piece of software installed on the devices that is connected to the management console. It reads any information on the device and sends it back to the management console.

The commonly shared database between the Agent and the Manager is called Management Information Base (MIB). In short, MIB files are the set of questions that the SNMP Manager can ask the Agent. The Agent collects this data locally and stores it, as defined in the MIB.

The primary protocols that SNMP implements are the User Datagram Protocol (UDP) and the Internet Protocol (IP). SNMP also requires Data Link Layer protocols such as Ethernet or Token Ring to implement the communication channel from the management to the managed Agent.

SNMP’s simplicity and connectionless communication also produce a degree of robustness. Neither the Manager nor the Agent relies on the other for its operation. Thus, a Manager may continue to function even if a remote agent fails. When the Agent resumes functioning, it can send a trap to the Manager, notifying it of its change in operational status. The connectionless nature of SNMP leaves the recovery and error detection up to the Manager computer and even up to the Agent.

MIB FILE.
The SNMP V3 MIB file can be downloaded directly from the La Marche website. Under “Products”, go to the “A12B” model, scroll down to the “Documents” tab

Scale Factor.
The Settings, Alarms and Status will appear on the right pane window. The scaling factor of all the settings is 0.1 (i.e. 60.5V will appear as 605V).

Traps.
The following Traps can be sent by the A12 / A46 unit.

sensing board.
AC_HIGH_ALARM_STATUS| AC Voltage High AlarmNote: Only available with optional AC sensing board.
