If LonWorks is in
free topology configuration
, activate the 51
ohm terminator by closing the
JP1
on the Lonwork Xboard.
if two TS2 are connected on the same channel (shared load
configuration) insert
JP1
just in one device.
If LonWorks is in
bus configuration
, place two terminators (with
resistance values of 100ohm 1% ½W) at each end of the bus and
remove (if it is present) the terminator for free topology
configuration by opening the
JP1
on the Lonwork Xboard.
if two TS2 are connected on the same channel (shared load
configuration) remove JP1 from both the devices.
Check1: Once the LonWorks bus is properly
connected and the TS2 switched on the DL4 yellow
Led (LonWorks service) must be OFF and the DL5
Green Led (LON/MIP Communication activity) must
blink regularly. The two led are located on
LonWorks Xboard.

Check2: Once the LonWorks bus is properly
connected, the RTUs wired and the TS2 switched on
use the RTU Service button to verify if the LonWorks
is properly connected. See RTU installation guides
to know where the Service button is located.
Connecting the network cable
The network cable must be a 10/100 BaseT standard unshielded
CAT5 cable terminated with an RJ45 male connector.
It needs to be plugged on
T1
connector.
