Connection diagram
*1
Use the twisted pair cable for SDA/SDB and RDA/RDB.
*2
Set the terminating resistor selector to "330 ".
*3
Set the terminating resistor setting switch of the GOT main unit to "Disable".
1.4.3 Terminating resistors of GOT
*4
Connect a 330 terminating resistor to the GOT to be a terminal.
*5
Make sure to ground a cable shield line by applying Class D Grounding.
*6
For the cable for converting D-sub9 pin connector to terminal block, refer to the following.
