1.0 Overview

A BRIDGE separates two network segments within the same logical network (subnet).

A ROUTER forwards data across internetworks (different subnets).

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.

IP9xx Series

The IP Series is a high-performance wireless ethernet bridge and serial gateway. Alternately, a Master IP Series unit may be configured to operate as a wireless ethernet router (and serial gateway).

When properly configured and installed, long range communications at very high speeds can be achieved.

The IP Series operates within the 902-928MHz ISM frequency band, employing frequency hopping spread spectrum (FHSS) and also, for

1.1Mbps operation, digital transmission service (DTS) technology.

They provide reliable wireless ethernet bridge functionality as well gateway service for asynchronous data transfer between most equipment types which employ an RS232, RS422, or RS485 interface.

The small size and superior performance of the IP Series makes it

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

ideal for many applications. Some typical uses for this modem:

1.1 Performance Features

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

 transmission within a public, license-exempt band of the radio

spectrum1 - this means that the modems may be used without access fees or recurring charges (such as those incurred by cellular airtime)

 maximum allowable transmit power (1 Watt)  longest range  transparent, low latency link providing reliable wireless IP/

ethernet communications with constant baud rate over distance

Key performance features of the IP Series include:

1 920-928MHz, which is license-exempt within North America, may need to be

factory-configured differently for other areas: contact Microhard Systems Inc.

2.0 Quick Start

Use the MHS-supplied power adapter or an equivalent power source.

To ensure that the IP Series unit is at its DEFAULT factory settings, once it has powered-up and the SYS LED is ON (after 1 minute), press and hold the front CFG button for 8 seconds - the SYS LED will initially blink, then be on solid, and then the unit will reset.

Note: Some OEM customers will have their specific factory defaults loaded.

IP9xx Series

This QUICK START guide will enable you to promptly establish basic IP connectivity between a pair of IP Series in a point-to-point (ref.

5.1) configuration. Note that the units arrive from the factory with a Radio Configuration

of ‗Remote‘ and the Local Network setting configured as ‗Static‘ (IP

Address 192.168.1.254, Subnet Mask 255.255.255.0, and Gateway

192.168.1.1).

The IP Series configured above is now the REMOTE IP Series for your Point-to-Point IP Series network.

With these two IP Series on a test bench, and configured as per the preceding, a wireless link will be present between the two units. This may be confirmed by noting that the RSSI (3 front panel LEDs) are illuminated.

Next, the ethernet connections will be made. continued...

2.0 Quick Start

To connect an IP Series to a PC, an ethernet CROSSOVER (not a straight-through) cable must be used.

IP9xx Series

The ethernet connections are dependent upon what is available to work with for the test configuration. For the purposes of this QUICK START, the assumption is that a LAN connection is available (with Internet connectivity) and that the PC is connected to this LAN.

 Disconnect the PC‘s LAN connection from its NIC card

and insert the now ‗loose end‘ of the ethernet patchcable

into the rear ETHERNET RJ45 connector at the rear of the MASTER IP Series.

 Using a CROSSOVER cable, connect the PC‘s NIC card

RJ45 jack to the ETHERNET RJ45 connector on the REMOTE IP Series.

At this point there is a wireless connection between the PC and the LAN, and you should be able to go about your typical networking activities, including accessing the Internet (via the LAN).

Also, by opening a web browser and entering the IP address of either

IP Series, you will be taken to the respective unit‘s Web User Inter-

face LOGIN window.

If communications not available as outlined above:

 Verify the RSSI LEDs on the front of each IP Series are

illuminated.

 Verify TX (red) LED activity on the front of each IP Se-

ries.

 Observe the rear of each IP Series, specifically the

ETHERNET connection: the green LINK LED should be illuminated (indicating proper cabling) and the amber (ACTIVITY LED) should also be flickering—indicating DATA traffic at the ETHERNET connector.

 If using Windows XP, the firewall function could inhibit

desired data traffic. Anti-virus software may also have a negative impact.

3.0 Hardware Features

IP9xx Series

The IP Series is a fully-enclosed unit ready to be interfaced to external devices.

Any IP Series may be configured as a Master, Repeater (or Repeater/Slave), or Slave. This versatility is very convenient from a

3.2 IP9xx Indicators

3.2.1 Front Indicators

Alarm LED (Amber)

Located at top/left of COM2 port, illuminates when there is a load/ transmitter impedance mismatch—indicating a possible problem in the antenna system.

MHX Status LED (Green)

Located at top/right of COM2 port, illuminates when the MHX core module is powered-up and okay.

TX LED

The transmit (TX) LED is illuminated when the IP Series is transmitting data wirelessly.

RX LED

This LED, when illuminated, indicates that the modem is synchronized and/or receiving valid packets of data.

SYS LED

The System Status LED operation is described in the following table:

System Mode SYS LED Status

Normal On Recovery Fast Blink (3 per second) Loading (e.g. on normal power-up) Slow Blink (1 every 2 seconds) Upgrading Slow Blink (1 every 2 seconds)

Table 3D: SYS LED Operation

Upon initial application of power the SYS LED will be illuminated for approximately 20 seconds, after which time it will being to blink slowly (loading) for an additional 25 seconds, then stay ON ‗solid‘ (indicating it has achieved its specific operational status).

3.0 Hardware Features

IP9xx Series

When initially cabling between devices, pay close attention to the Activity LED to confirm that proper patchcable types are being used.

Receive Signal Strength Indicator (RSSI) (3x Green) LEDs

As the received signal strength increases, so does the number of illuminated RSSI LEDs, starting with the furthest left. RSSI is calculated based on the last four valid recieved packets. For robust wireless communications performance, strive for a minimum of 2 RSSI LEDs being lit.

Initially, a remote unit‘s RSSI LED‘s will ‗scan‘ (cycle from right to

left, each LED being on for 300ms in turn). Once the unit acquires

synchronization with the network, a ‗steady‘ RSSI reading will be

displayed. A Master updates its RSSI indication upon receiving valid packets

from remote units. It takes into consideration packets received from both Repeaters and Remotes.

A Repeater will base its RSSI reading on valid packets received from Slaves; if the Slaves are silent for 2 seconds, the Repeater will display an RSSI value based on valid packets received from the Master.

Signal strength is calculated based on the last four valid received packets with correct CRC.

3.2.2 Rear Indicators

Collision LED (Amber)

Located at top/left of the ETHERNET connector, illuminates when there is a collision on the ethernet interface.

Activity LED (Green)

Located at top/right of the ETHERNET connector, illuminates when there is data activity present on the ethernet interface.

4.0 Operating Modes

Throughout this manual, ‗Remote‘ refers to a Remote as defined in Section 4.4; the

general term ‗remote‘ applies

to an IP Series Repeater and/ or Remote - i.e. non-Master

IP9xx Series

An IP Series may be configured for any operating mode: this is very convenient for purposes of sparing and becoming familiar with their configuration menus.

4.1 Master

One per network, the source of synchronization for the system. The Master controls the flow of data through the system.

4.2 Repeater

Required only if necessary to establish a radio path between a Master and Remote(s); stores and forwards the data sent to it. Synchro-

nizes to Master and provides synchronization to ‗downstream‘ units.

If a local device is attached to a Repeater‘s serial data port, the Re-

peater will also behave as a Remote (aka Repeater/Remote).

As they are added to a radio network it is good practice to use the values 2-17, sequentially, for Repeater Unit Addresses.

Adding one or more Repeaters within a network will HALVE the throughput; the throughput is halved only once, i.e. it does not decrease with the addition of more Repeaters.

If there is a ‗radio (signal) path‘ requirement to provide Repeater

functionality, but throughput is critical, the repeating function may be

accomplished by placing two IP Series at the Repeater site in a ‗back

-to-back‘ configuration. One IP Series would be configured as a Re-

mote in the ‗upstream‘ network; the other a Master in the ‗downstream‘ network. Local connection between the modems

would be accomplished with a crossover cable (for the ethernet connection). Each modem would require its own antenna; careful consideration should be given with respect to antenna placement and IP Series configuration.

4.3 Remote

Endpoint/node within a network to which a local device is attached. Communicates with Master either directly or through one or more Repeaters. See Sections 5.3 and 5.4 for information regarding ‗Slave-to-Slave‘ communications.

5.0 Network Topologies

The RADIO network topology determines the paths available for the movement of data.

Take this important fact into consideration when selecting a network topology.

IP9xx Series

The IP Series may be configured to operate in a number of different operating modes and participate in various network topologies.

Note: This section describes radio network topologies in general and includes examples of corresponding Radio Configuration settings. Refer to section 6 for further detailed information regarding configuration options.

5.1 Point-to-Point (PTP)

In a Point-to-Point network, a path is created to transfer data between Point A and Point B, where Point A may be considered the Master modem and Point B a Remote. Such a PTP network may also involve one or more Repeaters (in a store-and-forward capacity) should the radio signal path dictate such a requirement. (Note that a Repeater may also concurrently function as a Remote, i.e. it may pass data to and from an attached device(s).)

A PTP configuration may also be used in a more dynamic sense: there may be many Remotes (and Repeaters) within such a net-

work, however the Master may have its ‗Destination Address‘

changed as and when required to communicate with a specific remote unit.

An example of a basic PTP network consisting of two IP Series is on the next page.

Notes re Example 5.1.1:

 Configuration options are based upon the chosen Op-

 The DESTINATION UNIT for the MASTER is the UNIT

 For a PTP system, RETRANSMISSIONS on a MAS-

erating Mode of the unit: select the Operating Mode first.

ADDRESS of the REMOTE, and vice versa (noting that

the MASTER‘s Unit Address (not visible) is preset, and

must remain as, ‗1‘).

TER is not as critical a setting as it is in a Point-toMultipoint (PMP) system.
