CSA Class 1 Division 2 Option

CSA Class 1 Division 2 is Available Only on Specifically Marked Units

If marked this for Class 1 Division 2 – then this product is available for use in Class 1, Division 2, in the indicated Groups on the product.

In such a case the following must be met: The transceiver is not acceptable as a stand-alone unit for use in hazardous locations. The

transceiver must be mounted within a separate enclosure, which is suitable for the intended application. Mounting the units within an approved enclosure that is certified for hazardous locations, or is installed within guidelines in accordance with CSA rules and local electrical and fire code, will ensure a safe and compliant installation.

The antenna feed line; DC power cable and interface cable must be routed through conduit in accordance with the National Electrical Code.

Do not connect or disconnect equipment unless power has been switched off or the area is known to be non-hazardous.

Installation, operation and maintenance of the transceiver should be in accordance with the transceiver’s installation manual, and the National Electrical Code.

Tampering or replacement with non-factory components may adversely affect the safe use of the transceiver in hazardous locations, and may void the approval.

The wall adapters supplied with your transceivers are NOT Class 1 Division 2 approved, and therefore, power must be supplied to the units using the screw-type or locking type connectors supplied from Microhard Systems Inc. and a Class 1 Division 2 power source within your panel.

If you are unsure as to the specific wiring and installation guidelines for Class 1 Division 2 codes, contact CSA International.

1.0 Overview

A SERIAL GATEWAY allows asynchronous serial data to enter (as through a gate) the realm of IP communications.

The serial data is encapsulated within UDP or TCP packets.

The IPn3G is a high-performance 3G Cellular Ethernet/Serial/USB Gateway. Equipped with 2 serial data ports, 1 USB, and 1 Ethernet Port, the IPn3G provides complete access to remote devices. Using the vast established infrastructure of cellular networks, the IPn3G can provide data services anywhere coverage is provided.

While private wireless networks can provide wireless data services, using FHSS ISM bands, or

secure dedicated licensed radio’s, coverage is only available where radio’s, repeaters, and other

equipment is deployed. Achieving a wide coverage area generally involves many radio units, antennas, possibly private or shared towers and large amounts of planning.

The IPn3G operates on HSPA & Quad Band GSM cellular networks, using 3G and/or EDGE/ GPRS technology to provide fast and reliable data transfer.

The small size and superior performance of the IPn3G makes it ideal for many applications. Some typical uses for this modem:

 SCADA  remote telemetry  traffic control  industrial controls  remote monitoring  LAN extension

 GPS  wireless video  robotics  display signs  fleet management

1.1 Performance Features

Key performance features of the IPn3G include:

 communicates with virtually all PLCs, RTUs, and serial devices through either one of

two available RS232 interface, RS422, or RS485

 fastest serial rates: 300 baud to 921kbps  advanced serial port supports legacy serial devices, including RTS, CTS, DSR, DTR,

and DCD.

 Easy to manage through web- or text-based user interface, or SNMP  wireless firmware upgrades  system wide remote diagnostics  advanced security features  industrial temperature specifications  DIN rail mountable  Optional Class 1 Div 2  Available as OEM solution

Supporting co-located independent networks and with the ability to carry both serial and IP traffic, the IPn3G supports not only network growth, but also provides the opportunity to migrate from asynchronous serial devices connected today to IP-based devices in the future.

2.0 Quick Start

This QUICK START guide will walk you through the setup and process required to access the WebUI configuration window and to establish a basic wireless connection to your carrier.

Note that the units arrive from the factory with the Local Network setting configured

as ‘Static’ (IP Address 192.168.0.1, Subnet Mask 255.255.255.0, and Gateway

192.168.0.1), in DHCP server mode. (This is for the Ethernet Adapter on the back of the IPn3G unit.

2.1 Installing the SIM Card

 Before the IPn3G can be used on a cellular network a valid SIM Card for your

Wireless Carrier must be installed. Insert the SIM Card into the slot as shown

To reset to factory defaults, press and hold the CFG button for 8 seconds with the IPn3G powered up.

The LED’s will flash

quickly and the IPn3G will reboot with factory defaults.

Main Antenna (SMA) (GPS & Diversity not shown)

2.0 Quick Start

 Connect A PC configured for DHCP directly to the ETHERNET port of the IPn3G,

using an Ethernet Cable. If the PC is configured for DHCP it will acquire a IP Address from the IPn3G.

 Open a Browser Window and enter the IP address 192.168.0.1 into the address

bar.

The factory default network settings:

IP: 192.168.0.1 Subnet: 255.255.255.0 Gateway: 192.168.0.1

The factory default login:

User name: admin Subnet: admin

It is always a good idea to change the default admin login for future security.

 The IPn3G will then ask for a Username and Password. Enter the factory de-

faults listed below.

192.168.0.1

The Factory default login:

User name: admin Password: admin

2.0 Quick Start

 Once successfully logged in, the System Summary Window will be displayed.

 To establish basic wireless connectivity with your carrier, the information in the

Carrier > Config menu must be completed as provided by your carrier.

Carriers may require different information to be filled out. Contact them for specific connection information.

For SIM Cards issued with Dynamic IP addresses most carriers simply require the correct APN. SIM Cards assigned Static public IP address often require a login details.

Carriers require the following information:

Always Required: Access Point Name (APN)

Some Carriers Require: Authentication Type User Name Password

2.0 Quick Start

 Verify connectivity with your Wireless Carrier by selecting Carrier > Statistics

or System > Summary. Your carriers name should appear next to the Network entry and the Activity Status should read as: Call in progress

 If you do not see “Call in Progress” you are not connected to or communicating

with your wireless carrier.

 Check that the SIM card is installed correctly.  Verify that the proper antennas are installed correctly  Verify the APN assigned by the carrier.  Re-Enter the login details, if required by the carrier, to ensure any typing

 You see “Call in Progress”, but no Internet Access. Check the WAN IP Address in

the Carrier > Statistics or System > Summary screens. If an IP Address is not shown, check the APN and login details for errors.

 Refer to Section 4.0 WebUI Configuration to configure serial ports, USB, or any

4.0 WebUI Configuration

The Web User Interface (WebUI) is a browser based configuration method that allows a user a graphical interface to configure, test and troubleshoot a IPn3G unit. Any standard web browser can be used and no additional software is required. Using the Web User Interface a user can:

 Remotely or locally configure a IPn3G unit, including:

 Network settings  Radio configuration  Serial Port configuration  Security  USB  Retrieve unit revisions  Update system firmware  Much more...

In this section, all aspects of the Web Browser Interface, presented menus, and available configuration options will be discussed.

4.0 WebUI Configuration

4.1 Logon Window

Upon successfully accessing the IPn3G using a Web Browser, the Logon window will appear.

For security, do not allow the web browser to remember the User Name or Password.

It is advisable to change the login Password (see Section

4.1.8.1). Do not FORGET the new password as it cannot be recovered.

The factory default User Name is: admin The default password is: admin Note that the password is case sensitive. It may be changed (discussed further along in this

section), but once changed, if forgotten, may not be recovered.

When entered, the password appears as ’dots’ as shown in the image below. This display

format prohibits others from viewing the password.

The ‘Remember my password’ checkbox may be selected for purposes of convenience,

however it is recommended to ensure it is deselected - particularly once the unit is deployed in the field - for one primary reason: security.

4.3 Network

4.3.1 Network > Summary

The Network > Summary tab gives an overview of the configuration of the Ethernet port on the IPn3G. This port is the RJ45 port located on the back of the IPn3G.

Within any IP network, each device must have its own unique IP address.

A SUBNET MASK is a bit mask that separates the network and host (device) portions of an IP address.

The ‘unmasked’ portion

leaves available the information required to identify the various devices on the subnet.

Image 4-6: Network Configuration , Local IP Configuration Submenu

Ethernet Port Status: The Ethernet port status shows the type and status of the local Ethernet

Link.

IP Address: This is the currently configured logical IP address of the IPn3G. This IP

address must be set statically in the Network > Config tab. This is generally set to a Private IP address for a local network.

IP Subnet Mask: The IP Subnet Mask is the current Subnet Mask being used by the unit to

define the subnet and host address of the IPn3G.

IP Gateway: The IP Gateway sets the default gateway for traffic leaving the IPn3G. Ethenet MAC: This is the physical MAC address of the RJ45 Ethernet Port of the back of

the IPn3G

USB MAC: For quick reference, this is the physical MAC address of the USB port on the

front of the IPn3G, when it is configured as a NDIS Ethernet Interface. See the USB section for more information.

4.3.2 Network > Statistics

The Network > Statistics tab displays a variety of parameters which apply to the traffic through, and status of, the physical Ethernet port (hardware interface) on the rear of the IPn3G.

Received and Transmitted information are applicable to the local data traffic into and out of the IPn3G, respectively. Errors which are counted include alignment, frame check sequence (FCS), frame too long, and internal MAC. The dropped packet count could increment if, for example, the network layer was too busy to accept the data.

The FIFO errors are related to interface-specific hardware. Collisions occur on all Ethernet networks being that Ethernet operates as a logical bus. The

amount of collisions is typically related to the number of devices on the attached network and the amount of data being moved.

The Transmit Carrier count relates to carrier sense errors.

4.3.4 Network > Config

The Network > Config tab allows the configuration of the Ethernet port on the IPn3G (Rear RJ45). This port is configured as static port and must be configured by the user if the default values are not to be used. By default this port acts as a simple DHCP server, allowing the IPn3G to assign IP addresses and enable communication to attached devices. Caution must be taken not to connect the IPn3G to an existing network where a DHCP server may already be running.

Within any IP network, each device must have its own unique IP address.

A SUBNET MASK is a bit mask that separates the network and host (device) portions of an IP address.

The ‘unmasked’ portion

leaves available the information required to identify the various devices on the subnet.
