Instruction manual

XWEB 500 – rel.1.0
2.1.3 THE TTL OUTPUT
• The instrument with RS485 on board do not need any kind of external interface module.
• For instruments with external interface: keep the TTL cable away from power cables or frequency
sources.
• The XJ485 external interface must be connected with TTL cable to the instrument with TTL compatibility.
2.1.4 SERIAL ADDRESS OF THE INSTRUMENTS
• Each instrument must be defined by its unique address.
• Check the address into the Adr parameter value. 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.
2.1.5 TERMINATION RESISTOR
To keep balanced the RS485 the beginning and the end of line must be closed with a resistor of 120Ω. If
XWEB 500 is placed at the beginning or at the end of the line, please active its termination resistor by
adding a jumper in position 2 (JMP2 on the back side of the unit). DO NOT add the jumper if XWEB 500
is placed in the middle of the RS485 line.
2.1.6 COMPATIBLE INSTRUMENTS
For a complete list please read Appendix C.
2.1.6.1 PARTICULAR DEVICE SETUP
• All controllers equipped with 2 serial addresses (XC400/600/800/900, XH200/300/400 etc.) must be used
with both addresses equal.
• iCHILLs need to activate a particular value in the “Advanced” section. User must check “Force Device
On status”. Remember to stop-start acquisition after this operation.
• To use non Dixell, but modBus compatible controllers (such as Energy Analyzer by Carlo Gavazzi)
follow this instructions:
a) Go to “Configuration” then “Devices”.
b) On the drop down menu “Actions” select “New...”.
c) A new pop-up window will appear: fill in the blank with the name of the controller and the ADR.
d) Choose the proper device model (e.g. “ENERGY_800000000000000”).
e) Press “Create”
