 data cable must be twisted pair 

•  In a free topology configuration, the sum total of the sections must not 

exceed 500m 

•  In a bus configuration, the sum total of the sections must not exceed 

2700m 

•  In a free topology configuration, activate the 50ohm terminator by placing 

the appropriate jumper on the FTT10A plug-in of the CTU-PLG06 board 
inside the TemaServer 

•  In a bus configuration, place two terminators (with resistance values of 

100ohm 1% ½W) at each end of the bus 

•  Check that the length of the L
