About this User Manual

This User’s Manual covers the information and procedures on installing, configuring and

using the Microflex MF24-AV/Avr/ADV/ADVr modules. This manual is also a reference for

persons who must perform or coordinate the tasks associated with programming and

managing a Multisite wireless network.

To control the video display and Pan-Tilt-Zoom functions in multipoint, you will need to

read Chapter 5 to learn how to use the Pelco KBD4000

keyboard. If you are using a

point-to-point video link and do not want to take advantage of the 4 camera inputs and

Quad View display of these 4 cameras, you do not require the KBD4000 and therefore do

not need to read this section. You will need, however, to read Chapter 4 to learn how to

program the DATA1 serial port of both video transmitter and receiver for the specific data

rate of the Pan-Tilt-Zoom system you wish to use.

For customers using a RS-485/422 port, you may need to change the port to RS-232

setting if you configuration of the module is required. Please review Appendix E for

converting from RS-485/422 to RS-232 and vice-versa (Appendix G for FV module)

For customers who have ordered a Line Level audio interface and plan to use a leased or

dry line, please refer to Appendix G for interface assistance.

Prerequisite Knowledge

Throughout the user's manual there are explanations and procedures that presume

working familiarity with radios, as well as basic digital data communication concepts and

practices, and an understanding of the concepts underlying telecommunication systems.

If you are not familiar with the concepts and practices involved in these disciplines, we

recommend that you familiarize yourself with them before proceeding.

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

CHAPTER 1 Overview

1.1 Product

The Microflex is your solution for reliable and cost-effective point-to-point or

multipoint wireless video communications. This module supports video and data

and/or telephony applications.

Capabilities of the Microflex are:

• All digital multipoint networking using Demand Assigned

TDMA/TDD access

• Supports up to 16 remote video, voice and data terminals

• Protocol transparent point-to-multipoint polled data port

• Support of multiple point-to-point data ports (up to 16)

• User-friendly PC/WindowsTM based system programming and

Multisite Network Management (MNM)

1.2 Features

Microflex provides the following features:

• Up to four (4) video cameras per transceiver modules

• One or two integrated analog telephone line interface (subscriber

or telco interface) and/or line level audio

• One or two asynchronous data ports (RS-232 or RS-485 levels)

• Reliable polled data communications using error detection and

correction algorithms

• Capability to operate in PBX or DOD (direct outward dial) voice

mode

_____________________________________________________________________________________________

1.3 Applications

The Microflex is capable of operating in a point-to-point as well as a point-to-

multipoint environment.

In a typical point-to-multipoint configuration, one Microflex must be set in master

mode to act as a network controller (typically installed at the base). It communicates

with several remote Microflex (up to 16) set in slave mode, on a single microwave

frequency. If a single remote Microflex is used, the system becomes a point-to-point

link.

___________________________________________________________________

Chapter 4 provides a comprehensive description of the MNM configuration software. The

Microflex is typically shipped with its factory default configuration unless indicated

otherwise on the configuration sheet attached. The MNM software may have to be used

to configure each Microflex for the required application.

Figure 2- Microflex AV/ADV – External view

The Microflex electronics is enclosed in a weather-tight cast aluminum module. All

cable entries and the indicator are mounted on the underside of the module to

maintain its weather-tight properties. The underside of the Microflex integrates one

(1) visual indicator with the following function:

• STATUS - Bi-color indicator (Green or Red)

This indicator illuminates Green when the module is operating normally and has

not detected an internal fault. It will turn Red at power up if the module detects

an internal fault. It will flash Green during radio firmware update (see chapter 4;

configuring the network with the MNM software). Steady off at power up also

indicates an internal failure.

1.5 Internal Description

Figure 3 - Microflex – Internal description

All connections to the Microflex including power, video, data and audio cabling are

made via pluggable industrial terminals. The signal description for each terminal is

indicated on a cabling label inside the enclosure.

____________________________________________________________________________

Care must be taken not to mix a Microflex FXS interface and FXO interface when

connecting the audio signals. Connecting a telephone line (FXO) instead of telephone

set can damage the FXS sub-module. A label at the back of the enclosure indicates the

audio option selected (O for FXO, S for FXS and L for line level).

____________________________________________________________________________

The industrial terminals are mounted on an interconnection board. This removable

board integrates a two stage surge/lightning protection circuit providing industrial

type protection for the main electronics.

____________________________________________________________________________

Each surge or lightning strike weakens the protection circuitry. It is recommended in

lightning prone geographical areas and as part of a maintenance program, to replace the

protection board every 2 years. Please contact ComLink factory for part number and

ordering procedure.

____________________________________________________________________________

The interconnection board connects to the main Microflex board via a pluggable

ribbon type cable assembly. If this ribbon needs to be disconnected for

maintenance, do not pull the ribbon as this may damage the cable assembly. Grab

the connector on the main PCB side and pull carefully.

The main board integrates five (5) visual indicators for troubleshooting as well as an

RF signal strength (RSSI) bargraph indicator to align the antenna and determine the

signal margin available:

• STATUS (DS1) - Bi-color indicator (Green or Red)

This indicator is equivalent to the external STATUS LED indicator. It illuminates

Green when the module has not detected an internal fault and is operating

normally. It will turn Red at power up if the module detects an internal fault. It

will flash Green during radio firmware update (see chapter 4; configuring the

network with the MNM software).

• POWER (DS2) - Bi-color indicator (Green or Red)

This indicator illuminates Green when there is at least +10VDC supplied to the

interconnect board and the power supply used has an appropriate capacity

(typically 1A @ 15 VDC). It will illuminate Red if power is below +10 VDC, if

capacity is insufficient or if there is an internal problem creating excessive power

consumption.

• COMMS (DS3) - Bi-color indicator (Green or Red)

This indicator flashes Red during power-up if the radio module is not properly

detected. Following power-up the LED behavior will depend on the module

configuration:

(a) Master Mode Configuration:

It will flash Green at a rate of 2 flashes per second following powering-up

sequence. It will remain in this state if it is able to communicate with a remote

Microflex set in Slave Mode. If it cannot communicate with a slave Microflex, it

will flash Red at a rate of 2 flashes per second. It will flash Green at a rate of 8

flashes per second when there is voice or data activity between the module and

another Microflex or when the remote slave Microflex identifies itself (once every

30 seconds).

(b) Slave Mode Configuration:

If it is not capable of communicating with a master Microflex It will remain off

following powering-up sequence. It will flash Green at a rate of 2 flashes per

second if it is able to communicate with a master Microflex. It will flash Green at

a rate of 8 flashes per second when there is voice or data activity between the

module and a master Microflex or every time it transmits its ID to the master

Microflex (once every 30 seconds on average but at random times).

_____________________________________________________________________________________________

__________________ ________________________________________________________

If the three (3) LEDs, power, Status and Comms are steady green simultaneously, the

Microflex is in its ‘’loader mode’’. Proper firmware has to be downloaded in the Microflex

for the module to be operational. Such download cannot be done over the RF network, it

must be performed locally (see chapter 4 for further details)

___________________________________________________________________

• PHONE/LINE (D1) – Green indicator

This indicator flashes 8 times per second in synch with the ring signal. The

indicator illuminates steady when a telephone call is in progress.

• CD (D2) - Green indicator

This is the RF carrier detect indicator. The LED behavior will depend on the

module configuration:

(a) Master Mode Configuration:

It will flash Green with varying intensity when activity is occurring in the network

(data or voice communications). The more the network is loaded, the more

intense the LED will glow. If there is no activity and the remote Microflex

modules can identify themselves to the master module, the LED will be on

momentarily every time it receives an ID packet (once every 30 seconds).

(b) Slave Mode Configuration:

It will flash green at a rate of at least 20 times per second (almost steady green)

when receiving a valid signal from the master module.

____________________________________________________________________________

The CD LED will not flash green if submitted to interference from nearby transmitters

operating in the same RF band. Such interference may however cause the LED to flash

intermittently by corrupting valid data packets received from another Microflex. The LED

may also flash intermittently if the signal received is at the limit of the receiver

sensitivity. The RSSI level can be used to differentiate between the two (2) conditions.

___________________________________________________________________

• RSSI (DS7 to DS16) - Green indicators

A ten (10) LED indicator bar graph is used to provide received signal strength

(RSSI). The RSSI indicators illuminate Green. RSSI values are not factory

calibrated and can have an error of +/- 4 dB as compared to true RSSI.

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

The minimum signal level at which the Microflex can operate depends on the data

rate setting. At high bit rate (558 kbps), the Microflex offers a -96 dBm receiver

sensitivity (@10-5 BER). By decreasing to medium bit rate (384 kbps), the

sensitivity increases to –98 dBm and at low bit rate (192 kbps), to -101 dBm.

____________________________________________________________________________

The bit rate should always be set to the minimum required to obtain the most robustness

to interference and the best receive sensitivity. The bit rate required depends on the

system load and the nature of the data transmitted. For most video applications the

medium data rate setting is a good compromise between link robustness and video quality.

For mixed data, audio, and video applications, the radio data rate used will depend on the

number of remote stations used. It is recommended to use medium rate for mixed signals

applications.

____________________________________________________________________________

The Microflex main electronics board integrates 3 switches offering the following

functions:

• RESET SWITCH 1 (SW1) – Reset to factory default

A reset-to-factory-default switch (SW1) can be triggered if the Microflex fails to

respond. This may be useful following the download of a corrupted or invalid

program or improperly programming the module using the MNM software (see

chapter 4). The switch must be held for at least 5 seconds while the power is ON

for a reset to be valid. Following a reset, the Microflex will need to be

programmed for proper operation in the network (see Appendix A for default

factory values).

1.6 Setting the Master or Slave Mode

The Microflex main electronic board integrates a two (2) position jumper to set the

module for Master or Slave mode operation. Refer to the illustration below for

proper position in both modes.

____________________________________________________________________________

A Multisite network must have a single Master module. If one Microflex is set in Master

mode, all other modules should be set in Slave mode. The Master module should ideally be

installed in an accessible location, typically at the base station. The only exception to this

is for a point-to-point video link. In point-to-point, it is best to set the MF24-ADV in

Master Mode and the MF24-ADVr is Slave Mode. This allows a higher video data

throughput (300 kbps sustained) and slightly higher quality.

CHAPTER 2 Microflex installation and operation

Your Microflex shipment should contain the following items:

• Microflex module with requested options

• Pole mounting bracket with two (2) stainless steel collars (for

0.75-2 inch poles unless an optional mount has been ordered)

• 15 VDC external power supply (Optional)

• Antenna (Optional)

• Microflex configuration sheet

• User’s manual (one set per system ordered)

• MNM based configuration diskettes (one set per system ordered)

___________________________________________________________________

Check the material against the packing list to make sure you have received everything. If

something is missing or if you discover shipping damage, please contact your distributor.

___________________________________________________________________

2.1 Microflex Setup Guide

Use the guidelines in the following subsection to assist you in cabling and installing

the Microflex.

STEP 1 Installing the Microflex module

The Microflex is shipped with a mounting bracket. This bracket is supplied with a

special water-sealing gel backing. This backing must not be removed in order to

maintain the enclosure weather-tight feature. Three (3) stainless steel screws are

also supplied to install the bracket on the back of the Microflex enclosure. Mount

the bracket to the back of the enclosure and align the screws with the mounting

holes. Tighten the three (3) screws firmly while being careful not to strip the

aluminum threads. Some gel may flow out from under the bracket while tightening.

This extra gel can be removed with water and mild soap or an alcoholic solution.

Using the mounting bracket and collars supplied, the Microflex can be mounted on

any pole with a 18-50 mm (0.75-2.0 inch) diameter. ComLink also supplies

mounting brackets for mounting on walls and larger collar size for mounting on light

poles or other large diameter poles. Contact ComLink factory if you require a

different mounting option than the one supplied.

_____________________________________________________________________________________________

STEP 2 Installing the antenna

The Microflex is designed for outdoor installation, next to the antenna. Such

installation minimizes cable losses thereby maximizing link margin. Install the

Microflex module with its antenna on an appropriate mast or tower. Depending on

whether the antenna has a pigtail or not, you may need to install a coaxial cable

jumper (with N connectors) between the Microflex and antenna. The coaxial cable

recommended is an RG-142 double shield (or equivalent) with a maximum length of

3 meters to reduce cable loss (use quality type N clamp connectors to ensure a

watertight setup).

____________________________________________________________________________

Install the Microflex module at the same elevation as the antenna for best lightning

protection. If the Microflex module is installed several meters lower than the antenna, a

2.4 GHz lightning arrester should be used.

Never exceed antenna gains of 11 dBi. The only exception is when

you have significant cable losses. For each dB of cable loss, you can

add 1dB of antenna gain

___________________________________________________________________

Always install the antenna away from wires, power lines and trees for optimum safety and

performance. For more information on antenna installation, refer to the manufacturer’s

documentation included with the antenna.

___________________________________________________________________

STEP 3 Connecting power, audio and data

Connect the power (12-15 VDC recommended), video, audio and data ports

according to the label at the bottom of the Microflex enclosure (see illustration on

next page). The video signal should be carried on RG-59 coaxial cable.

The power and audio signals can be carried using the same cable. This cable

should contain 4 to 5 pairs with an overall shield and have an AWG of 20 (0.81

mm diameter) or larger for optimum performance. Use 2 pairs for the audio and 2-3

pairs to carry power (this will reduce voltage drop between the power supply and the

Microflex).

The data should be carried using a low capacitance non twisted pair

communications cable with an overall shield. A 24 gauge (0.51 mm diameter) low

capacitance conductor will support long cable runs (50-80 meters) for RS-232

signals. The two (2) data ports can use a single multi-conductors cable.

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

____________________________________________________________________________

If you are planning to install a long cable extension between the Microflex and the

cameras, PLC/computer equipment and/or the phone equipment, it is highly

recommended to protect these equipments from lightning and power transients (the

Microflex is well protected and does not require additional protection). Several

manufacturers provide protection equipment for video, phone and data ports. ComLink

can provide a list of recommended equipment on request.

programming. Both Data1 port and Data2 port are configured as DCE interfaces.

They must be connected to a DTE interface for proper operation.

Connect the RS-232 TX, RX and GND signals (RTS/CTS not required) to the

available COM port of your PC running the MNM software. The MNM software will

automatically convert the Microflex Data port 1 to terminal mode (configuration

mode) when started. The Microflex converts its Data port 1 back to its data

application mode following 30 seconds of inactivity from MNM on Data port 1.

___________________________________________________________________

In point-multipoint applcations, DATA 1 is used to transfer PTZ commands. If you have

ordered an RS-485 interface, DATA 1 is configured for RS-485 signal levels. You will not

be able to communicate with the module using a computer and MNM software in such case.

A RS-485 to RS-232 signal converter plug must be used to communicate between the

Microflex and the computer. Such item is not expensive and available from most

telecommunication equipment distributor.

___________________________________________________________________

STEP 5 Verifying the indicators for proper operation

Upon power up, the indicator STATUS indicator on the outside of the enclosure

should turn STEADY GREEN. Review Chapter 1 to understand how the indicators

on the Microflex main board should behave under normal conditions.

____________________________________________________________________________

If the POWER or STATUS indicator turns red momentarily (2 seconds or more) or stays

off at power up, there is a problem with the Microflex or the power supply. Please

contact ComLink technical support team for assistance.

____________________________________________________________________________

STEP 6 Completing the Installation

You have now completed the Microflex initial installation. Once the Microflex is

properly installed it will need to be configured. Please review Chapter 5 ‘’Using the

MNM Software’’ to complete this final step.

CHAPTER 3 Proper microwave network planning

The Microflex microwave sub-module provides a standard air interface for all Multisite

products. It offers a robust and highly reliable spread spectrum wireless link which can

span 50 kilometers with appropriate installation.

For best operation the network must be properly planned and the antennas must be

installed in such way as to obtain line-of-sight links. This chapter provides a

comprehensive review of network planning and propagation principles.

3.1 RF Planning

Successful operation of a Multisite network lies on the proper installation of the

wireless interface. Such installation requires five (5) phases:

1. Completing the initial network layout

2. Evaluating the system gain required for each link and selecting the

appropriate antennas to use

3. Verifying the line of sight and Fresnel zone clearance for each link within the

network

4. Carrying out an on-site survey (optional)

5. Completing the final system commissioning.

This section presents a step-by-step approach to completing the phases outlined

above.

3.1.1 Network Planning

A Multisite network can be configured in multiple ways.

Figure 6, Figure 7 and Figure 8 present some common configurations. The first

step is to establish a network plan based on initial area topology and distances

between each remote station and base.

Figure 8 - Multipoint Network with Two Repeaters

In situations where there are no repeaters, the antenna installed at the base

station should be elevated as high as possible to provide a clear line-of-sight with

all remote stations.

___________________________________________________________________

To establish wireless links exceeding 10 kilometers, it may be necessary to install a

telecommunication tower at the base (if none are available). A more cost-effective

solution could also be to install a repeater on an existing telecommunication tower in the

vicinity of the base.

___________________________________________________________________

To install several repeaters in the system, an adequate mast or tower height must

be planned for each repeater supporting multiple links.

_____________________________________________________________________________________________

3.1.2 Evaluating System Gain Requirements

To establish a link between two antennas, the following requirements must be

met:

Path loss < system gain (radio gain + antenna gain - cable losses).

The radio gain, at a specific bit error rate (BER), is equal to the transmission

power less the radio receiving sensitivity. The radio gain provided by the

Microflex depends on the power output and data rate selected via the MNM

software. At maximum power and medium data rate (384 kbps), the radio gain is

122 dB. At minimum data rate (192 kbps), the radio gain is 125 dB.

The antenna gain will vary according to the model selected. ComLink offers a

selection of antennas to meet the propagation specifications of various

configurations (See Table 1).

Using the maximum radio gain with the maximum allowed 11 dBi antenna gain

(including cable losses) at both ends, the achievable system gain is 147dB (at

192kbps data rate).

Table 1 – Antenna Gain

Since the Microflex can be installed next to the antenna, it is easy to minimize

coaxial cable losses. This allows the use of smaller, lower cost antennas.

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

The path loss must always be lower than the system gain. The difference

between the two is the path safety margin. This margin ensures the link to be

functional despite changes in system gain due to heavy rain, temperature

variations, antenna misalignment and overall electrical and mechanical system

aging. The changes due to rain and temperature variations are presented in

Table 2.

Impact of rain and temperature on Microflex

Condition Reduction in system gain

Rain Up to 0.5 dB/10 km

T = - 40o C Up to 1.0 dB

T = + 55o C Up to 2.5 dB

Table 2 – Weather dependent ratings

Antenna misalignment does not contribute much to path loss in Multisite networks

because most communications take place between an omni antenna (base or

repeater) and a directional antenna (remote station). Aligning such antenna

combination is not as critical when compared to the alignment of two directional

antennas.

A good rule of thumb in a Multisite network is to use a 15-20 dB security margin

to take into account the above factors in addition to multipath fading.

The difficult part in planning a solid link is to evaluate the path loss. There are

many factors that affect the overall losses. Two of these important factors

include topology of the path and in-band and out-of-band interference. Short of

conducting an actual on-site survey, these factors could be hard to assess. A

good starting point is to establish the free space path loss for the link. Free

space path loss is the predominant contributor to the total path loss of a line-of-

sight radio link.

To establish the free space path loss, ComLink has prepared a reference in

Table 3 combining free space path loss at 2.4 GHz to a security margin of 15 dB

and 20 dB. The security margins selected are based on field experience. They

are not calculated from scientific equations and should only be used as a general

guideline.

Table 3 – Distance Vs Path Loss

As mentioned earlier, maximum system gain is 147 dB. This is achievable at a

data rate of 192kbps using the maximum allowed 11 dBi antenna gain (including

cable losses) at both ends.

The example below illustrate how to calculate the required system gain based on

the path loss provided in Table 3.

Example: A link at 2.45 GHz must be established between a base and a

remote station 10 kilometers apart. Select the appropriate antennas for the link.

a) Path loss = 135 dB (from Table 3)

b) Required radio system gain = path loss = 135 dB.

c) Assuming the system is operating at maximum power and medium bit

rate:

(i) Radio gain = +24 − (−98) = 122 dB

(ii) Total antenna gain = Path loss − Radio gain

= 135 − 122

= 13 dB

For point-to-point operation between two (2) Microflex modules, two (2) 8 dBi flat

panel antennas could be used.

For multipoint networking, an omni antenna must be installed at the base. A 6 dBi

omni could be used at the base with an 8 dBi flat panel antenna at the remote

station.

Additional link margin

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

___________________________________________________________________

At 2.4 GHz, radio waves are highly attenuated by dense foliage. A link established in the

fall or winter season may be affected adversely in the spring and summertime, if it is

established below tree level.

___________________________________________________________________

Once the network RF gain plan has been empirically calculated, the minimum

antenna elevation at each site to minimize path loss should be established. The

Fresnel zone clearance, the earth’s curvature (can be ignored for links shorter

than 12 kilometers) and any physical obstructions along the path have to be

considered.

3.1.3 Verifying Line of Sight and Fresnel Zone Clearance

Unless it is a very short link distance (typically less than 1-2 kilometers) the path

between the two antennas must be free of obstacles that could disturb

propagation. Such path is called a line of sight path. If there are obstacles, radio

waves will be in part absorbed and in part diffracted by the obstacles (multi-path

fading). Even if operating in such circumstances, links could be established.

However, results are highly unpredictable.

The first requirement of a successful link is therefore a clear line of sight path.

There is a second requirement related to the beam-width of a radio signal. The

beam-width of a radio signal transmitted between two antennas is an elliptical

area immediately surrounding the visual path (see Figure 9). It varies in

thickness depending on the length of the signal path and the frequency of the

signal. The region outlined by this beam-width is known as the first Fresnel zone.

VISUAL LINE OF SIGHT

FIRST FRESNEL

ZONE (F1)

Figure 9 - Difference Between Fresnel Zone and Visual Line of Sight

_____________________________________________________________________________________________

The Fresnel zone is always thicker at the mid-point between the two antennas.

Therefore a path that appears to be a perfect line of sight path between the base

and a remote station may not be adequate for a radio signal.

In practice, it has been determined that a radio path can be considered a line of

sight path if it has a clear opening through 60% of the first Fresnel zone (0.6 F1).

Table 4 presents the value of 0.6 F1 for various signal path distances.

Table 4 – 0.6F1 Values at Various Distances

A common problem encountered in the field and related to the 0.6F1 clearance

rule is a mountain obstruction. The proposed visual path may just barely clear a

mountain but the “radio line of sight” won’t. In such case, the signal will be

partially absorbed and diffracted. Increasing the height of one antenna (or both) is

the only alternative to reduce path loss.

3.1.4 On-Site Testing

Before finalizing the system commissioning, verify the quality of each link

especially if large distances are covered (> 10 kilometers). If in-band interference

is suspected, taking a spectrum analyzer on site to scan the frequency band is

recommended.

To complete a site survey, first install the Microflex configured as a Master at the

base station and power it up. If a repeater station is planned in the system, the

Microflex can temporarily be installed at the repeater site to verify the quality of

the repeater-to-remote station links.

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

The Microflex in master mode continuously transmits a beacon (at 10 msec

intervals) to remote stations and this, whether or not, the data or audio port is

active. This beacon provides a good signal for RSSI measurement at each

remote station.

To conduct the remote site survey proceed as follows:

STEP 1.

Install the proper antenna at the remote location proposed

STEP 2.

Connect the Microflex configured as a Slave to the antenna

STEP 3.

Align the antenna to obtain maximum RSSI

STEP 4.

Note the RSSI value

____________________________________________________________________________

If the RSSI bargraph does not reach the third LED indicator at low bit rate and the fourth

indicator at medium bit rate, there might be insufficient margin to guarantee a

continuous high quality link (BER > 10

-5

). Considerable temperature variations and heavy

rain can cause path loss variations of up to 3 dB. There are two (2) options to decrease

path loss:

1) Increase the height of the base / repeater or remote antenna, or

2) Increase the gain of the antennas used (within the 11 dBi limitation, including cable

losses).

If these options are not feasible, a repeater station may have to be installed strategically

along the path.

____________________________________________________________________________

_____________________________________________________________________________________________

3.2 Coping with Interference

In most countries, the 2.4 GHz license free band is not regulated by a government

agency and this absence of frequency coordination can result in interference

between various systems. Fortunately, there are existing tools that can be used to

avert interference:

(1) RF channel selection

(2) PN code selection

(3) Security code

(4) Antenna selection

___________________________________________________________________

Interference is probably not a concern for a Multisite network installation in a rural area.

In urban area, radio licenses are limited creating an increased demand for wireless

products at 2.4 GHz. The potential for interference is therefore greater in urban areas.

It is recommended to do a site survey with a spectrum analyzer before planning the

Multisite network to identify zones of potential interference within the band.

___________________________________________________________________

(1) RF channel selection

At 2.4 GHz, eleven (11) non overlapping channels are available. This selection

enables the co-location of eleven (11) Multisite networks in the same area without

substantial performance degradation.

(2) PN code spreading and selection

The Microflex employs direct sequence spread spectrum coding. With this

coding scheme, a pseudo-random sequence (PN code) is used to spread the

signal over a much wider band than required by the base-band modulated data.

The wider the signal is spread, the better the radio receiver is at discriminating

between a valid signal and an interfering signal.

The Microflex uses 16-bit PN sequences. Some radios implement longer

sequences (64 bits or more), however most unlicensed products (such as 802.11

compliant wireless LAN radios) use 11-bit PN sequences to maximize data rate

within a given bandwidth. With a 16-bit sequence, the Microflex module provides

sufficient interference rejection in most environments and to most unlicensed

products.

The best PN codes are pseudo random, non-correlating sequences of bits. With

such PN codes, two independent radio links at the same frequency will not

interfere with each other. The signal isolation provided by two distinct PN codes

is proportional to the PN code’s length.

The Microflex module supports nine (9) non-correlating PN codes. Given

sufficient antenna separation, It can be possible to co-locate nine (9) non-

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

interfering networks at the same frequency using 9 different PN codes with low

cross-correlation. The networks must be planned such that no radio receives a

signal from the co-located network at a stronger level than a signal from its own

network. In practice, this may be difficult to achieve. Directional antennas would

have to be used with all Microflex radios installed in close proximity to each other

and belonging to different networks.

(3) Security code

A 16 bit security code is used to guarantee network security and prevent

eavesdropping using another Microflex module. This security code also provides

some protection against interference.

(4) Antenna Selection

To determine isolation between two antennas at selected frequency bands, three

(3) critical parameters must be considered:

1) Radiation pattern (including front-to-back ratio).

2) Gain of the antenna.

3) Antenna polarization.

Strategic selection of antennas based on these parameters can significantly

lower interference between co-located systems.

A multipoint network must use an antenna with a wide horizontal radiation pattern

at the base (or repeater site) to communicate with all remote stations. If the

remote stations are located within a localized area instead of being scattered all

around the base, a common practice is to use a directional antenna with a

reduced horizontal beamwidth. This will reduce interference from co-located

systems installed outside the 3 dB beamwidth of the antenna. In such

circumstances, good antennas to use are flat panel antennas. They typically

offer up to 120°, 3 dB beamwidth and front-to-back ratios greater than 20 dB

A co-located radio far enough outside the 3 dB beam-width will see its signal rejected by up to

20 dB by the antenna.

CHAPTER 4 MNM Configuration Software Integration

This chapter provides information on installing and using the MNM (Multisite Network

Manager). The MNM is a user friendly and easy-to-use Windows

compatible software.

This software configures all Multisite modules within a network. It allows you to set PABX

and DOD phone connections as well as polling and point-to-point data links. The software

also acts as an on-line diagnostic tool by providing the status of all network nodes.

4.1 Installing the MNM

To install the MNM, follow these steps:

Insert the MNM Setup Disk 1 into drive A and select Run from the taskbar.

Figure 10 – Run Dialog Box

Type: a:\setup.exe and click OK (as in figure 1).

Figure 11 – Welcome Setup Dialog Box

The installation procedure might have to replace some files in use by other

programs. For this reason a welcome screen prompts you to exit setup and close all

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

running applications (figure 2). When all applications are closed continue setup by

clicking on <Next>.

Read carefully the Release Note and then press <Next>.

The installation will start and install MNM to the default path C:\Program Files\MNM\.

Once completed, you will be asked to restart your computer, choose Yes and click

on <Finish>(figure 3).

Figure 12 – Setup Complete Dialog Box

4.2 Using Multisite Network Manager (MNM)

The MNM is designed to configure a Network. It can also be used to configure each

module individually before installing the network.

4.2.1 Launching the MNM Programmer

Launch Windows 95/98TM.

Connect the COMM Port used by the PC to one of the unit in the network. The

connection must be done on the Data Port #1.

____________________________________________________________________________

If you have ordered RS-485 signal level for Pan-Tilt-Zoom support, you will need a signal

converter plug-in module to convert the RS-485 signals to RS-232 signals for

communication with the computer on DATA 1.

____________________________________________________________________________

From the taskbar select Start | Programs | MNM.

_____________________________________________________________________________________________

The MNM main window should then appear (figure 4).

Figure 13 – MNM Main view

MNM uses (by default) Comm Port 2 to communicate with the local module. To

change serial port select menu Options | Serial Port…and select the appropriate

Comm Port from the drop-down list and click OK (see figure 14).

Figure 14 – Communication Configuration Dialog Box

___________________________________________________________________

The Local Module is the Multisite unit connected directly to the computer’s serial

communication port. The Multisite Network Manager software uses a special escape

sequence that allow it to switch automatically the data port into a management port,

whatever the baud rate or the configuration of this port. For this reason, once the

computer is connected to a unit in the system, no additional manipulations are required for

the communication to begin.

___________________________________________________________________

_____________________________________________________________________________________________

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

____________________________________________________________________________

MNM may not work properly if two (2) or more Microflex are set in Master mode. There

must be a single Microflex set in master mode before using MNM.

____________________________________________________________________________

4.3 Main Operations

Only two simple operations are needed to configure a Multisite network: the

configuration download and the configuration upload.

The configuration download retrieves all the properties of each unit in the network.

All information is stored in a database and displayed to the user. Some

configurations are read-only and some others are read-write. To meet the

specifications of your application, you may modify the read-write properties as

required. Once the configuration is completed, the upload operation will send the

new configuration to each unit and save it permanently.

The MNM main window is divided into four distinct areas (figure 15): the menu bar,

the tool bar, the network list and the property tabs. Each of these parts is described

in the following sections.

CHAPTER 5 Using the KBD4000 in a Multisite Network

This Chapter describes the installation of a Pelco KBD4000

keyboard controller (or

equivalent) in a Comlink Multisite

video network. In a multi-point network, the keyboard

must be used

to select cameras, views, and other options.

The Pelco KBD4000 can also be used in a point-to-point network to support Quad View

display and future advanced options. Note however that in point-to-point, if a single

camera is used, the data port can be made transparent to support any Pan-Tilt-Zoom

protocol.

There are important facts the users should know about the utilisation of a KBD4000

in a

Multisite Network:

• The KBD4000

must be connected to a receiver unit (MF24-AVr/ADVr or FV).

• The KBD4000

must be configured in <multiplexer mode> for proper operation.

• The video receiver (MF24-AVr/ADVr or FV) DATA1 serial port must be set to

“Genex Mode” to support the KBD4000 keyboard (see Chapter 4)

In ‘Genex Mode’, the MF24-Avr/ADVr (or FV) emulates a Pelco Genex

multiplexer. The

receiver is therefore interchangeably referred to as a video receiver or multiplexer

throughout this Chapter.

ComLink has plans to release a Windows based software which emulates the KBD4000

. Please

contact our Technical support team to have an update on the release date.

_____________________________________________________________________________________________

5.1 Configuring the KBD4000

The KBD4000 must be pre-configured before being operational

. To setup the

KBD4000

, follow these steps:

Remove the DIP switch cover plate from the rear of the keyboard and set the

switches to these positions:

1. Set switches 1, 2 and 3 to OFF (select the multiplexer mode of operation).

2. Set switch 4 to ON (to enable the non-polled communication mode).

3. Set switch 5 to OFF (unused).

4. Set switch 6 to OFF (to disable turbo pan feature).

5. Set switch 7 to ON (to address all cameras consecutively).

6. Set switch 8 to ON (to enable programming mode of the Multisite Video

Receiver).

5.2 Configuring the Microflex Video Receiver

To properly interface the KBD4000

to the Multisite video receiver, DATA1 of the

Microflex video receiver must be configured properly using the MNM configuration

software (see Chapter 4). To do so, follow these steps:

1. Launch the Multisite Network Manager software (MNM).

2. Select the receiver unit in the left panel.

3. Click on the Data tab and select DATA1.

4. Configure the data port as follows: Connection = “none”, baud rate =

“9600bps”, Correction = ”Off”, handshake = “none”, parity = “odd”, Genex

mode = “On”.

5. Press the UPLOAD button to set the receiver with this new configuration.

____________________________________________________________________________

The video receiver DATA1 port supports RS-485 signal levels only (not RS-232). To

program the video receiver using MNM, you will need a signal converter plug-in module

to convert the RS-485 signals to RS-232 signals for communication with the computer on

DATA 1.

_____________________________________________________________________________________________

Comlink might already have completed this pre-configuration at the factory. In this case, ignore

these steps.

5.5 Using the KBD4000

in a Microflex Video Network

The KBD4000

is an essential tool in a Multisite video network. It allows you to

configure the multiplexer options (title, date, time etc.), to select the cameras to

display, to perform the pan, tilt and zoom functions (if PTZ drivers are used).

The multiplexer automatically selects the most common operating parameters.

However, some minimal programming may be required in order for your system to

operate properly. The next sections describe all KBD4000

functions supported by

the Microflex.

5.5.1 Microflex ID’s

In a Multisite video network, the unit ID must be set to a specific range.

STEP 1 A Microflex video receiver (MF24-AVr/ADVr or FV) must have a

unit ID between 1 and 16.

STEP 2 A Microflex video transmitter (MF24-AV/ADV) must have a unit ID

between 1 and 63.

To modify the unit ID, refer to Chapter 4 (using the MNM configuration software).

5.5.2 Camera selection in Full Screen Display

To enter the Full Screen Display mode, push the < > key once.

To select a camera in Full Screen Display mode, you must type the camera ID

number, then the <CAM> key.

Example: to select camera 66, type: <66>, <CAM>.

___________________________________________________________________

The camera ID is calculated from the Microflex transmitter unit ID (1 to 63) and with

camera input (1 to 4): CAM ID = (UNIT ID – 1)*4 + Tx cam input.

For example, to select the camera input 2 on the Multisite transmitter unit 17, you must

use CAM ID = 66 ( (17-1)*4 + 2).

To select NO CAMERA, set CAM ID to 256:

<256>,<CAM>

Since the Genex protocol supports CAM IDs between 1 and 252, the Microflex video

transmitters ID’s must be between 1 and 63. Unit ID’s must be configured with the

MNM configuration software.

APPENDIX B - Telephone System Operation

This paragraph is a reference on how to use the Multisite telephone system under

different operation mode. Each Microflex can be programmed to support one of two

telephone modes; (1) PABX mode and (2) DOD (direct outward dial). It is also possible to

combine these two dialing modes in a Multisite network.

• PABX MODE FEATURES:

All Microflex modules programmed for PABX mode must dial “9” to obtain an

external telephone line unless the auto-dial check box is selected.

When dialing “9”, the Microflex (FXS) will contact the Microflex (FXO) with the

lowest ID number. If it is busy, it will contact the next Microflex (FXO) with the

lowest ID number and so on until it tries all Microflex FXO extensions. If there

are no extensions available a busy signal will be played back (the outside line

search takes less than 1 second).

For incoming calls on the FXO line, a stutter tone is played. By dialing the correct

Microflex (FXS) extension the call will be connected to the Microflex extension.l

Internal calls between Microflex (FXS) are supported without tying up external

telephone lines by dialing the appropriate extension number.

• DOD MODE FEATURES:

To operate in DOD mode, a Microflex (FXS) must be associated with a single

Microflex (FXO or FXS).

There is no need to dial “9” from a Microflex (FXS) since it is a direct line.

All incoming call on the external FXO line are directly transferred to the

associated Microflex (FXS).

Microflex AV/ADV/AVr/ADVr North-American user’s manual / Rev 1.2

APPENDIX C - Weatherproofing Coaxial Connections

The Microflex are normally mounted outside. Weatherproofing of coaxial connections is

required for successful long-term operation.

Most antenna problems are caused by coaxial cable connections that loosen due to

vibration, allowing moisture to penetrate the connector interface. ComLink recommends

that all outdoor cable connections be weatherproofed using a procedure similar to the one

described below. To facilitate the task, the sealant tape is supplied with each antenna

shipped (the customer is responsible for providing the electrical tape).

STEP 1.

Beginning as shown in Figure 19, by overlapping half-width, wrap sealant tape over

entire connection.

tape connection. While stretching tape, begin at center of formed sealant tape and

wrap towards one end approximately one inch beyond end of sealant tape.

Insure tight electrical tape coverage onto cable jacket. Without breaking electrical

tape, reverse direction and wrap to other end, again extending approximately one

inch beyond end of sealant tape. Again insure tight coverage onto cable jacket.

Reverse direction again and wrap electrical tape to center of connection and stop.

APPENDIX E - Switching from RS-232 to RS-485 for a

MF24-ADV/ADVr

If you have ordered a Microflex with an RS-485 port, DATA1 has been factory configured for

RS-232 operation and 2 RS-485 chips have been shipped separately in an ANTISTATIC bag.

This is because you may need to program the Microflex locally via the DATA1 port and using

the MNM configuration software prior to or during installation.

Once you have completed the configuration of the Microflex, proceed as follows to switch the

data port to RS-485 mode:

1. Power the unit OFF, then wait at least 1 minute.

2. Insert the 2 RS-485 chip at positions U4 and U7 on the interconnection board (see

illustration on next page for exact chip location)

NOTE: Observe STATIC PRECAUTIONS when handling the RS-485 chips

3. Change the jumpers JP4,5,7,8,9 according to the table below (see illustration on

next page for exact jumper location).

4. Install jumpers at JP2 & JP3 to terminate the RS-485 receive line (jumpers are

included with the RS-485 chip package).
