On the same line, each controller is normally programmed with its own unique serial address, through the
Adr parameter. Refer to the installation manual of the instrument itself for the access and modification
procedure. To obtain a simple description of the categories to which they belong, divide the programming of
the addresses progressively. Some special cases are listed on the following pages.
To keep the RS485 line balanced, the ends must be terminated with a 12
0Ω resistor. If the XWEB is at one
end of the RS485 line, it is advisable to insert the 120Ω termination resistor on the last instrument and on the
XWEB. To activate the EOL resistor, insert the jumper in position 2 (word TERM). DO NOT insert the jumper
if the XWEB is in the middle of the RS485 line.
Notes on the use of polarization resistors (POL-, POL +)
In order to avoid false signals on the bus, polarization resistors must be inserted. It is important to note that
they must be inserted in one and only one place in the network, otherwise the communication will
deteriorate; the node in which they are inserted is irrelevant even if it could be convenient to do so on the
XWEB, checking that the other instruments of the serial network have not already integrated and permanent
them.
5.2.1 CONFIGURATION FOR XC400/600/800/900 AND XH200/300/400 SERIES
These instruments have two serial addresses and must be configured in the same way. Refer to the
instrument's installation manual to learn about the access and editing procedures.
5.2.2 CONFIGURATION FOR XJA/XJP/XJM MODELS
XJA/XJP/XJM series instruments are configurable with one or more modbus addresses. Refer to their
installation manual for the configuration procedures.
