Roaming sensors –R
A roaming transmitter is a specific type of transmitter that is used in applications such as vehicle monitoring where the transmitter can be away from the base station for long periods (up to 30 days). When the transmitter is away (roaming), it logs the temperature internally and automatically uploads to the base station when it returns within radio distance.
The logging frequency can be set from 1 to 30 minutes allowing a maximum of 30 days of data storage.
One wire sensors
The transmitters use TekTroniks range of intelligent sensors. Each intelligent sensor integrates the sensing element, analogue front end, analogue to digital converter and digital processing to provide a linearised digital output. All of which are embedded into the sensor cable. Each sensor is provided with its own unique id.
Temperature and humidity sensors can be supplied calibrated directly from the factory.
Network Security
The data that is transmitted through the system consist of very small packets of data, typically in the region of 20-30 bytes. The data consists of network management data and sensor data. Network data is to keep the network up to date, enable devices to join while the sensor data provides real-time sensor readings together with status information such as battery usage.
The application protocol is specifically designed for low powered networks in industrial control and monitoring applications. All data in AES128 encryption to provide data security.
NOTICE
These transmitter do not use WIFI or any IP protocols and as such will only communicate with our base station. There is no network bridge, protocols or software that allows third party threats to use this network in order to gain access to the IP network connected to the base station.
Product recycling/disposal
Consider recycling equipment and packaging.
Dispose of the product and packaging in accordance with local and national legislation.
Operation
This section contains information on installing sensors, battery and pairing the transmitter to the base station and should be performed prior to installation.
Removal of rear cover
If the transmitter is attached to a magnetic wall mounting bracket, pull apart so that you can see the rear of the transmitter. Ensure that it is clean and wipe away any water/ surface moisture.
Removal
If the rear cover is fitted with an optional retaining screw (1) remove this first.
Hold the sensor housing firmly in one hand. Using the other hand firmly press the retaining clip (2) down and gently pull the cover away from the main body. The cover should hinge at the bottom (4) until it becomes free.
Replacement
Holding the cover at about 45degrees from the main body, insert the locating lugs (3) into the corresponding slots (4). Hinge the cover back into place while providing slight downward force to ensure the locating lugs remain in place. Once the cover is in place, hold the enclosure in both hands and use your thumbs to push firmly on the cover (5).
If required, insert the optional retaining screw.
Installing Sensors
The connectors for the sensors are located in the rear compartment. See section 3.1 for removal of the rear cover. The image below details a dual channel configuration, for single channel versions, RJ socket (2) is not present.
To insert the sensor simply align the plug in front of the socket and push in until a click is heard. Tug lightly on the cable to ensure that it is located correctly and held in place.
To remove the sensor simply push down on the small leaver while pulling out the cable.
Transmitters are provided with a rubber cable seal to help reduce water ingress when using external sensors.
The seals have a cut along the hole to allow it to be positioned over the cable (1). Once attached maneuver the seal into position (2) so that the ridges on the casing (3) match the ridges on the seal. Once aligned, press firmly into place.
Internal sensors (P2-WS201)
P2-WS201 transmitter variant is supplied with an internal temperature sensor. The sensor plugs in to the internal RJ socket and simply curls round into the rear compartment. The cable seal is replaced with a solid bung.
Battery Installation / Replacement
The battery is located in the rear compartment. See section 3.1 for removal of the rear cover.
With the rear cover removed carefully remove the battery from the sprung mounting clip by pulling the battery backwards away from the clip.
Once the battery is removed, leave the sensor for 60 seconds to drain any internal capacitance.
Place the new battery in the mounting clip with the positive terminal matching that shown on the image opposite.
NOTICE
Only replace battery with the same type.

Type : Lithium Thionyl Chloride, 2450mAh, 3.6V, AA Cell
Part Number : LS14500
Battery Life : 5 years + (in normal operation)
Side button / Test mode
A button located on the left side of the transmitter (1) provides functionality for both sending a test transmission and initiating the pairing process.
A single button press initiates the test mode. The transmitter will send out a test signal and wait for a response. The status LED (2) is used to indicate the response.
A single short flash (A) indicates that the transmitter is not paired.
An initial single long flash indicates that the transmitter has sent a test signal. If this is followed by a second long flash (B) then the transmitter successfully received a reply.
If the transmitter does not receive a reply, it will start searching for a network, indicated by rapid flashing of the LED.
At the end of the rapid flashing, if the transmitter connected with a network and received a reply it will display a further single flash.
If the transmitter was unable to detect a network, move closer to the base station and retry.
NOTICE
If the button is held for 5 seconds to initiate the pairing process without initiating the pairing process on the corresponding base station, the transmitter will clear and previous pairing resulting in data not being sent to the base station.
Pairing to a base station
A transmitter has to be paired with the base station before use. The user should be familiar with the base station pairing process and will need administration rights. See the base station user manual for further information.
For the pairing to be successful, the pairing has to be initiated on both the base station and the transmitter and the transmitter needs to be within radio distance of the base station.
Follow the following steps.
- Press and hold the side button on the transmitter. After about 5 seconds the LED will show green. Keep the button depressed.
- Click the join transmitter key on the link manager. You should then see a countdown.
- Release the side button.
The LED on the transmitter will flash as it is pairing with the base station. A series of rapid flashes indicate the transmitter is establishing a connection. After the connection is complete, a further single one second flash will indicate that the join has been successful.
NOTICE
After joining a single press of the side button will perform a network test. See section 3.5.
Installation
The information in this sections covers the installation considerations on mounting and siting the product for best operation.
NOTICE
Do not place device near or above a heat source or any device which could cause overheating.
NOTICE
Do not position equipment so that it is difficult to operate.
NOTICE
Install all equipment in conformity with the technical specifications given in this documentation.
Mounting
The transmitter has magnetic feet (1) and can be directly mounted onto a metal (ferrous) surface or magnetically onto the mounting bracket. The bracket caters for various mounting options;
- Mounting holes (2) for securing onto a wall or flat surface with screws.
- Nut holes for magnetic mounts (3).
- Flat areas (4) for double sided tape or pads for mounting onto a flat surface.
- Holes for cable tying onto poles or racking (5).
Additionally, Slots (6) to allow the transmitter to be cable tied to the bracket.
Transmitter placement
For best possible operation of the radio transmitter, consider the following placement guide when mounting a transmitter.
- Mount vertically
- Where possible place the transmitter with the antenna in about 20cm of free space.
- Keep the antenna away from mains cable or LAN communication cables.
- Keep away from noisy electrical items such as PC’s, monitors and printers.
- If possible mount externally of metal enclosures or metal clad rooms.
NOTICE
Mounting in any of these location will not mean the transmitter will not work, it may just attenuate the signal resulting in the transmission distance being reduced.
Transmission distance
Transmission range depends on a number of factors most of which are not under the control of the installer. The following table provides a guide for the typical range to expect. Transmitters with external antennas can typically increase transmission distance by 25%.
For large installations or with lots of internal wall or structures, routers can be added to expand the operating distance of the transmitters.
Ingress Protection
The enclosure is rated to IPX5 which means it has been tested against low powered jetting water from any direction (internal antenna only).
The testing was completed with the rear cover screw in place and is necessary to achieve compliance. The screw helps maintain a constant pressure to hold the rear cover against the internal seal.
To further enhance the water ingress protection and to increase the life of the seal it is recommended to use a silicone O-ring grease around the seal of the rear compartment.
For harsh environments such as wash down areas it is always recommended to use an IP68 rated enclosure.
If the enclosure is not located within a wet environment then it is not necessary to use the screw.
