Transmission TT201 - TT206 Guide

Wireless Transmission Overview

This guide covers uses of the Analogue wireless transmission kits.

These units are relatively straightforward, there are a few provisos when deciding their
use.

1. How far do they need to be transmitted
2. Is there line-of-sight between the two points
3. Are there any environmental factors that can block use
4. Is telemetry required

• TT-201 – Internal Only 200 Meter range
• TT-202 – Telemetry Only Transceiver
• TT-204 – 1 Channel 300 Meter range
• TT-205 – 1 Channel 3km Range
• TT-206 – 4 Channel 2km Range
• TT-207 – 1 Channel 1.5km Range
• TT-208 – Ethernet transmitter (See Separate TT-208 Guide for more details)

Step 1: Distance Transmission

When Choosing the correct kit it's important to know the distances involved, while we do
transmitters that can go extreme ranges, it's inadvisable to put them in a situation where the distance is extremely short, as this can cause issues with the signal being too strong, leading to interference or even no image at all.

The units do have a potentiometer on board the transmitter which can allow you to adjust the strength of the signal, however this will only be effective up to a point, so always be sure to check your distances and then match it to the correct distance transmitter.

Step 2: Line of Sight

With the exception of the TT-201 and the TT-202 the units require a clear line-of-sight between the two points. That said they can be used as repeaters by running a link cable between to kits, this way you can work your way around a potential block of signal.

Please be aware that by line-of-sight we mean a clear uninterrupted signal between the two points, no trees or foliage can interfere with the signal.

Step 3: Environmental Factors

The Units operate using a 5.8GHz signal, possible causes of issues can be:

• Other transmitters in the same range
• Metal walls or corrugated iron sheeting
• Strong enough satellite signals (Dishes right next to the transmitters)
• 5.8GHz band phone systems
• 5GHz band Wifi transmitters
• Heavy EM radiation

Location is important so always be sure to check for these factors, with other devices operating in
the same band there is a workaround in that each unit has an addressable dip switch which changes the level of frequency, this can help by moving the frequency of the unit above or below the range of the interference.

Step 4: Telemetry

The Final check is whether or not you are using a PTZ camera.

Currently you will require a pair of TT-202 units to transport the PTZ control signal, these operate
on the same 5.8GHz frequency, however, they are bidirectional transceivers using a general broadcast antennae this means you do not require line-of-sight. They do not transmit video, and we do not at present support coaxial telemetry transmission
