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.
