*1 Set the terminator switch built in the farthest inverter from the GOT to ON (100 ).
*2 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 "330
Ω ".
