FUNCTION
*1 Set the terminating resistor selector to "OPEN".
*2 Set the terminating resistor selector to "110 ".
1.4.3 Terminating resistors of GOT
*3 Set the 1pair/2pair signal selection switch to "1pair" when using the connection conversion adapter.
In that case, transition wiring is not necessary between SDA and RDA or SDB and RDB.
*4 This is the connector pin No. of GT14, GT11, GT105 , or GT104 main unit.
*5 Make sure to ground a cable shield line by applying Class D Grounding (100 or less).
*1 Set the terminating resistor selector to "OPEN".
*2 Set the terminating resistor selector to "330 ".
