*1
Use the twisted pair cable for SDA/SDB and RDA/RDB.
*2
Set the terminating resistor selector to "330 ".
*3
In the case of GT27, GT25(Except GT2505-V), GT23, set the terminating resistor setting to "Disable".
In the case of GT2505-V, GT21, set the terminating resistor setting to "330
Ω
".

1.4.3 Terminating resistors of GOT
*4
In the case of GT27, GT25(Except GT2505-V), GT23, connect a 330
Ω
terminating resistor to the GOT to be a terminal.
*5
Make sure to ground the shield of the cable with a ground resistance of 100 or less.
*6
For the cable for converting D-sub9 pin connector to terminal block, refer to the following.
