RS-422/485 connection diagram 6)
*1 The signal name differs depending on the series name. Refer to the following table.
*2 Short-circuit between the following terminals of the energy measuring unit or electric multi-measuring instrument which will be a
terminal.
By the short circuit of the following terminals, a terminating resistor with 120 is connected.
*3 When placing the GOT to the terminal, set the terminating resistor of the GOT to "Enable".
When placing the GOT to the position other than the terminal, set the terminating resistor of the GOT to "Disable".
1.4.3 Terminating resistors of GOT
*4 Ground a shield correctly.

By the short circuit of the following terminals, a terminating resistor with 120 is connected.
*3 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)
When placing the GOT to the terminal: Set the terminating resistor of the GOT to "110 ".
When placing the GOT to the position other than the terminal: Set the terminating resistor of the GOT to "OPEN".
1.4.4 Setting the RS-232/485 signal conversion adaptor
*4 For the RS232 setting, check "Enable the 5V power supply".
1.1.2 I/F communication setting
*5 Ground a shield correctly.
