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.
