Turn ON (100 ) the terminator switch for the most distant FR-E7TR from the GOT.
In the case of GT27, GT25(Except GT2505-V), GT23, set the terminating resistor of GOT side, which will be a terminal, to
"Enable".
In the case of GT2505-V, GT21, set the terminating resistor of GOT side, which will be a terminal, to "330Ω".
