RF SOLUTIONS TAURUS Series User manual

TAURUS
DS-TAURUS-2
Description
Taurus is a rugged RF Transmitter which can operate with many RF Solutions receiv-
ers to generate a Range Remote Control System. Taurus can operate in several
Modes of operation, providing short or longer range. It can be optionally set to re-
quest feedback from the receiver to provide the user with visual feedback, and can al-
so provide an automatic background “Watchdog“ Transmissions.
Housed in a IP66 rated waterproof enclosure, TAURUS has an internal rechargeable
Lithium battery which can be recharged via either the external microUSB socket (type
C) or wireless recharging pad (using a standard QI, Apple or Samsung Wireless com-
patible). Custom versions are available on request

Notes
1. Range is dependant on many factors in-
cluding the mode of transmission. Range
can be reduced by 75% in built up areas
with poor antenna, and environmental
conditions
2. Battery life quoted is approximate based
on 30 operations per day.
This sets the type of RF Transmission.
Possible options are FM, or LORA Modes 0 - 7
FM or LORA mode 0 provides the quickest re-
sponse; from Transmitter sw pressed to Re-
ceiver Relay output.
LORA mode 7 provides the longest operating
range but with the longest time delay of from
button press to receiver relay actuation..

TAURUS FM/LoRa Transmitter

RF Acknowledgment from Receiver - Warning!
When Acknowledgement is ON, TAURUS requests
an RF signal back from the receiver. Whilst in
theory if an RF signal can be transmitted one way
then it can be returned, in practice occasionally
the received acknowledgement many not pene-
trate as well as the Taurus transmitted signal.

To Set Acknowledgement Request
Acknowledgement Feature provides the user with
LED indication that the receiver has successfully re-
ceived the transmitters signal.
When activated the TAURUS Transmitter includes an
acknowledgement request within each radio trans-
mission. .
The response from the receiver is indicated on the
transmitter via the RED / GREEN LEDs.

TAURUS FM/LoRa Transmitter
DS-TAURUS-2
If enabled, TAURUS automatically transmits a back-
ground “watchdog” RF Signal approx. every ~45
secs,
RF Solutions Receivers with a Watchdog feature wil
hold a Relay contact “ENERGISED” as long as
Watchdog is regularly received confirming the
transmitter is in range and the system is operating
correctly.
When using Watchdog it may be useful to incorpo-
rate a Power Switch to avoid premature battery
discharge
A power switch can be incorporated If this is re-
quired please contact our sales Dept.

TAURUS FM/LoRa Transmitter
DS-TAURUS-2
When a switch button is operated TAURUS will trans-
mit a “Button Down” RF Transmission
When a switch button is released TAURUS will trans-
mit a “Button Up” RF Transmission
Continuous Transmit
TAURUS repeat transmits “button Down” in short
bursts for as long as switch button is pressed.
If the Acknowledgment is ON the receiver will reply
after each RF transmission burst.
This is ideally suited to momentary operation where
the receiver output needs to be active as long as the
user presses down a TAURUS Button .
State Change Transmit
TAURUS transmits an RF transmission only when the
switch button is pressed or released (i.e a state
change).
On each of these “state changes” TAURUS transmits
upto 4 transmissions, or, “RF packets” (which can be
seen by the GREEN LED flashing upto 4 times,
If the Acknowledgment is ON the receiver will reply
immediately.
After receiving an Acknowledgment the TAURUS will
cease sending any remaining of the 4 transmissions.

TAURUS FM/LoRa Transmitter
DS-TAURUS-2
It is quite difficult to find the open space to perform a LORA range test as the operating dis-
tance is so great.
Our Range Testing was conducted along the coastline of Brighton, UK seafront providing an open Line of
Sight Test.
Two TAURUS Transmitters we used with one as a transmitter and the other custom configured to be a
Transceiver. When the Transmitter was operated the Transceiver TAURUS received the signal and
acknowledged back to the transmitter Thus creating a simple PING PONG between the two.
1. The Transceiver was mounted on railings ~4ft from the ground.
2. We then took the transmitter along the coastline whilts intermit-
tently operating to test the signal along the way
3. As we carried out the test Line of sight was lost along with the sig-
nal. A Reliable signal was observed to about 3K range, thereafter the
signal became intermittent. When the Transmitter and Receiver re-
gained Line of sight a reliable signal was again observed. This contin-
ued for the available distance (about 12KM) at which point the ter-
rain prevented further testing. At the longest available range the sig-
nal was 100% reliable.
Test conditions
- TA= +21 °C
- VDD= +3.3 Vdc
- Dry, Broken Sunshine, Relative Humidity 45%, poor visability ~4KM with considerable ozone
Range Tests
Conclusion
The product performed as ex-
pected. Unfortunately we ran
out of land to test a LOS be-
yond 12Km ,so the maximum
range is further than tested
here.
It is also clear that the product
performs considerably better
when in LOS.
