2. RS485 CONNECTION
To be connected to the serial line all the Dixell Modbus instruments must be
provided with direct RS485 terminals or the “TTL”-RS485 interface (XJRS485 or
XJ485). Check the instrument manuals for more information. The RS485 line is
mainly based on two polarised terminals. Please pay respect to the right
sequence for all the devices connected to the serial line.
Follow these important instructions:
The RS485 serial line must reach all the instruments where they are installed.
Make sure of the wire polarities when screwing them into the instrument
terminals.
The cable must have 2 or 3 wires with shield, minimum section 0,5mm2(eg. the
BELDEN 8772).
From the XWEB 500 position the cable reaches all the instrument positions.
Do not execute loops or derivations:
Right connection

Wrong connection
Always keep the serial cable away from power cables.
Always keep the serial cable away from Electro-magnetic or frequency sources.
Do not connect shield to ground.
Do not connect the “Gnd (ground)” terminal.
Remember to draw a map of the line. This will help you to find errors if
something is wrong.
The instrument with RS485 have “+” and “-“ terminals, respect the polarity.
To keep the line balanced it is necessary a 100 Ohm resistor at the end of the
line (you can use the RS 485+ and RS 485- terminals of the last instrument
connected).

The TTL output
The instrument with RS485 on board does not need any kind of external
interface module. For instruments with an external interface: keep the TTL
cable away from power cables or frequency sources.
The XJ485 external interface must be connected with a TTL cable to the
instrument with TTL compatibility.
Serial address of the instruments
Each instrument must be defined by its unique address.
Check the address into the Adr parameter value of each instruments. Take
reference to the instruction manual of the instrument itself to find the right
procedure to enter the programming and set the value.
The easiest way to work with the category functions is to set the addresses
progressively for similar groups of instruments which have the same
application.

3. MODEM CONNECTION (“or point to point
connection”)
It represents the most common method where the LAN (intranet / Ethernet /
internet) is not available.
It is strongly advised to use a dedicated telephone line.
IMPORTANT: Use exclusively modem devices approved by Dixell.
Remember that many modems are not compatible with Linux.
The list of compatible models can be found under the menu: Configuration –
System - Modem.
In Windows XP, you will use the "New Connection Wizard".
1. From the Start menu, select Control Panel.
