XJ200 Installation and Operating Instructions
General Description
The XJ200 wireless communication modules are radio communication systems for con-
trolling and supervising units. The XJ200 consists of the XJ200 radio module P/N 318-5050
and its power supply PW-200J P/N 318-5051.
The XJ200 can cover a variety of functions within the monitoring network:
•Master: when it is connected to the X-WEB or E2 monitoring system.
•Slave/Repeater: when it is connected to the subnets of devices equipped with RS485.
•Repeater: when it is assigned the function as a simple bridge towards other subnets
that cannot be reached directly by the master.
The XJ200 modules enable 2-way communication between Dixell devices/modules
equipped with an RS485 output that are appropriately connected to each other and the X-
WEB or E2 unit, thereby replacing the connection via an RS485 cable.
Up to 15 devices can be connected to the same XJ200 (communication between the module
and the devices is via RS485), thereby covering several workstations with the same commu-
nication module. Up to 30 XJ200 modules can be connected to one (1) master XJ200.
The maximum distance possible between the XJ200 modules in an open space (with no
obstacles) is 200 meters (656 feet approx.). This distance can be remarkably reduced in the
presence of interference such as radio emitters, generators of electrical or magnetic fields or
solid objects that can affect the proper communication between the XJ200 modules.
The range of serial addresses allowed on the instruments connected to the XJ200 modules is
from 1 to 244.
Note that in order to work with the XJ200 modules, the instruments must be equipped with
an RS485 serial port and use MODBUS-RTU communication protocol.

or reception.
• If possible, avoid intermediate obstacles such as barriers, walls, floors and counters
between the modules.
• If necessary, pass through the obstacle using the cable and install the module on the
opposite side in order to have it in direct view with the master module connected to
the X-WEB or E2.
• The maximum distance possible between the XJ200 modules in an open space (with no
obstacles) is 200 meters (656 feet approx.).
• If the installation spans over a number of floors, try to position all the modules on the
same floor and connect the devices via cable in order to prevent communication prob-
lems due to obstacles caused by the floor or ceiling.

E2 and XJ200 Networking
XJ200 Wireless New Installation Procedure
E2-XJ200 Master Connection
In the new installation, you need to find a location in the store that has a direct line of sight
with at least one or two wireless modules (slave modules) on the sales floor. If the system
performs up to four hops, those in the indirect view can find their way to the master wireless
module location to them.
From the designated position, run a communication cable (three conductors) and wiring to
handle 24VAC, and depending on the distance, the wire gauge needs to be calculated. The
master module needs a power supply that takes 24 VAC and powers the wireless module
with 5VDC.

Commissioning a New Network
Once the master and slave modules are installed, wired and powered, you now may follow
these steps:
1. Press the service button on each slave module. This operation will have the slave module
send the master the list of nodes connected to it for the master to build a communication
path (during this phase all three LEDs flash every second).
2. After one to two minutes, each slave module provides a status using the “RADIO” or
“RS485” LED during the testing phase.
• If there is a good communication path, the “RADIO” will have a green LED.
• If there is a communication problem, the “RS485” will have a yellow LED. Try adjusting
the module and repeat the process by pressing the service button.
3. When the network is ready to operate, start the acquisition procedure on the E2. The
slaves and master modules will start to communicate when the E2 requires information
to the MODBUS modules and starts coming online.
Removing a Node from the Wireless Network
The master module can recognize if a node is removed from the network. If a node is
removed, the master module will act as follows:
1. The master module enters to “discovery phase” to find a new path to reach the offline
nodes. While in this phase, lasting up to three seconds, the master disregards the mes-
sages coming from the E2.
2. After the three discovery phases (up to three seconds per phase), the master stops for 20
minutes in the discovery phase, and forwards the messages through the last known path.
Every 20 minutes a new discovery phase starts.
3. If the node is actually removed from the network, it must be deleted from the E2, to
avoid the master module to keep on starting the discovery phase.
4. To remove a slave module, unplug the E2 MODBUS from the master module and initiate a
discovery phase by pressing the service button, to create a new path.
Adding a Node to the Wireless Network
To add a node to the wireless network, refer to Commissioning a New Network.

Troubleshooting
Problem Possible Cause Possible Solution
Device does not appear on
supervisory controller.
Device not commissioned in
supervisory controller.
Follow commissioning procedures for
supervisor controller.
Device appears on
supervisory controller, the
status goes “off line” but
returns to “on line” after a
few minutes.
Communication may have
been delayed to the
supervisory controller.
Check the supervisory controller’s
communication summary for percentage of
lost packets. If problem remains constant
with one particular module, reposition that
module or add a repeater.
Device appears on
supervisory controller but
status is “off line”.
Master is not reporting slave
module to the supervisory
controller.
Slave module is not communicating with the
master. Press Test button on slave module
and allow ample time to establish
communication. If the yellow LED remains
on, reposition the slave module to improve
line of sight with the master.
All devices appear on
supervisory controller but
status is “off line”.
Master is not communicating
with Slave modules.
Ensure that you have followed the
installation steps in the proper order. A good
communication path needs to be
established between the master and slaves
before connecting the supervisory controller
and commissioning devices. Install the
master as high as possible to ensure optimal
coverage.
A slave module is removed
from the network but
other modules seem to go
“off line” with it.
When a module is removed
from the network, the master
reconfigures the best
communication path to all
remaining slave modules.
Allow ample time for the master to
reconfigure the communication path. If
other modules do not return “on line” press
the Test button on the slave module that is
“off line”. If the module does not return “on
line”, it is possible that communication is
blocked. If this is the case, reposition the
slave module or add a repeater between the
master and slave.
A new slave module is
added to the network but
it does not appear as “on
line” on the supervisory
controller.
Ensure the line of sight to the
master is not obstructed.
Press the Test button and allow ample time
for the master to establish a new
communication path.
