1General Definitions
TWM-1886 Wireless Router module allows the extension of the wireless network area by connecting
to the coordinator or to another router. Basically, it is used to increase the communication distance
between the wireless coordinator and the wireless devices.
Wireless routers ensure that the data between two devices (coordinator-device, coordinator-router,
router-device, router-router) are transmitted without problems and the route the data will be
delivered through is determined. The coordinator assigns a unique address to all devices while
connecting to the network. Routers, however, use these addresses to get the data packages to be
delivered to correct targets. A wireless device can maintain the communication with the coordinator
in a network where routers are used, regardless of distances.
Wireless routers communicate with all devices on the network through the TLPWAN(1) protocol.
(1) TLPWAN (Teknim Low Power Wide Area Network) is a wireless communication protocol
developed by Teknim which allows low power consumption devices on a wider area in a stable
and safe manner by using two-way communication.

3Installation
Under this topic, the installation of TWM-1886 Addressed Wireless Coordinator module will be
explained step by step in details. Please read all steps carefully.
3.1 Mounting
The following articles must be followed carefully in order to provide a good communication with the
devices connected to the coordinator:
•Choosing a proper communication channel will make the communication between the devices
more stable. Channel selection can be made automatically or manually. If manual selection is
to be made, initially all transmissions in the environment must be detected with the RF-
analyzer and according to this, relatively the most available channel must be preferred. See
programming section for manual channel selection.
•The environmental factors such as high current lines, big metal objects, computers, network
lines, other cable lines, etc. that may interrupt the connection with the devices on the wireless
network must be avoided.
•There must be at least 2 meters of distance from other wireless devices.
•If possible, it must be mounted at least 2 meters high from and parallelly to the ground. The
antenna must remain at an angle of 90 degrees to the ground.
•It must be operated under the proper ambient conditions indicated in technical specifications.
Otherwise, the operating performance will be affected.
•A suitable location must be preferred by considering the communication distance when all
devices to be communicated are taken into consideration. Communication distance can be
seen in technical specifications.
The mounting holes of the module are located under the module cover. In order to access those, the
cover must be opened by gently pushing through the holes on the right side of the module by using a
flathead screwdriver.
3.1.1 Cable Holes
The holes through which the cables necessary for module connection will pass must be prepared
before wall mounting. For this purpose, holes must be broken open on the round points marked on
the product housing. Before breaking open the holes, the cards inside of the module must be removed.
The tabs holding the cards must be pulled gently in order to remove the cards.

Once the cards are removed, a gentle pressure must be applied behind the point to be broken open in
a manner to leave a space underneath by using a thick screwdriver in order to break open the holes.
The cards can be reinstalled and fixed after this procedure.
3.1.2 Wall Mounting
Mark the wall according to the 4 screw holes seen below and bore 4 holes on the wall by using a drill
according to the diameters of the wall plugs included in the pack. Insert the wall plugs into the bored
holes and fix the module on the wall by screwing it onto the wall.
Figure 1 –Mounting Hole Sizes
3.2 Antenna Installation
TWM-1886 Addressed Wireless Coordinator module is placed in the box with the antenna wire and
antenna housing disassembled. Ensure a good installation of the antenna in order to provide a good
communication between devices. Otherwise, there may be distance problems and communication
performance losses.
There are two superposed cards connected to each other in the module: The upper one of those is
TLPWAN-RF card, while the other serves as the Flashlink interface and control card. The antenna
terminal is located on the TLPWAN-RF positioned as the lower card. Pass the wire antenna through the
antenna input of the box and fix it on the terminal to the right as shown in the figure. Make sure that
the terminal screw is firmly tightened. An antenna that is not fixed properly may cause performance
loss.

3.3 Supply Connection
Pass the cables from cable holes and strip their ends at a proper length, then make the supply
connections as shown in the following connection diagram. Make sure that the terminal screws are
tightened firmly.
Figure 4 –Supply Connection Diagram
3.4 Module Interface
Warning: The supply connection of the wireless router must be made through an uninterrupted power supply. Since the
commands coming from the coordinator cannot be delivered to the devices in case of a power cut, the system will not
work properly.
Warning: Supply line must not be connected to the reset AUX output.

below in order to reset the router.
1. Press UP button for a long period (for 5 seconds).
2. Observe that only the fault led lights at the end of operation. The fault led will light only
because the tamper button is active.
4.2 Network Connection
For the router to be connected to a network, initially, check whether the router is connected to a
network or not by observing the heart led of the device. Follow the steps below for connecting the
router to a network.
1. The connection permission of the respective coordinator or router must be on before the
device is connected to the network. Turn on the connection permission of the coordinator or
router.
2. Press DOWN button for a long period (for 5 seconds).
3. The device will automatically start the connection operations. This operation lasts
approximately 20-60 seconds. During the operation, the L2 led will blink twice in every 2
