RS485 connection diagram 9)
Pin No. of temperature controller differs depending on the model. Refer to the following table.
Terminating resistor should be provided for a temperature controller which will be a terminal.
Set the 2-wire/4-wire terminating resistor setting switch of the RS-232/485 signal conversion adaptor as follows.
2-wire type/4-wire type : 2-wire type (1Pair)
Connect FG grounding to the appropriate part of a cable shield line.
Precautions when preparing a cable
(1) Cable length
The length of the RS-485 cable must be 500m or less.
(2) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(3) FUJI temperature controller side connector
Use the connector compatible with the FUJI
temperature controller side.
For details, refer to the user's manual of the FUJI
Connecting terminating resistors
(1) GOT side
When connecting a PLC to the GOT, a terminating
resistor must be connected to the GOT.
(a) For GT16, GT15, GT12
Set the terminating resistor setting switch of the
GOT main unit to "100 OHM".
(b) For GT14, GT11
Set the terminating resistor selector to "110 ".
For the procedure to set the terminating resistor, refer
to the following.
1.4.3 Terminating resistors of GOT
(2) FUJI temperature controller side
When connecting a FUJI temperature controller to the
GOT, a terminating resistor must be connected.
