Caution
Do not leave bits of wire in the un it, because they could cause fire , malfunction or trouble .
Insert the connecting cable into the designated connector securely to prevent malfunction.
Connect the wire for the AC power source with its designated terminal as described in this instruction
manual.
The IF-400 will be damaged if the AC power source wire is connected to an incorrect terminal.
When wiring terminals of the IF-400 at the terminal block, use corr ect fi tting ferr ules with an i nsulatio n slee ve
for the terminal screw .
Tighten the terminal screw within the specified torqu e. If excessiv e force is app lied to the screw when

1. Overview
1.1 Overview
The IF-400 is a communication converter to relay communications between a host computer/PLC
(RS-232C or RS-422) and controllers (Serial communication function RS-485, C5 option).
Shinko protocol and Modbus protocol are available.
The IF-400 can also be used as a repeater by connecting another IF-400 unit to the controller side
communication line.
The repeater will be the 31st connected unit, and up to 31 units of controller can be connected to the
repeater.
A maximum of 3 units of repeater can be connected.
Up to 95 units of controllers (Controller address is limited to 95) can be connected.
1.2 System configuration
1.2.1 When the IF-400 is used as a communication converter
When IF-400 is used as a communication converter, a maximum of 31 units of controller can be
connected.
(Fig.1.2.1-1)
1.2.2 When the IF-400 is used as a repeater
When the IF-400 is used as a repeater, more than 32 units of controller can be connected.
Communication line can be extended more than 1.2km.
Up to 3 units of repeater can be used, therefore, up to 95 units of controller can be connected
(A maximum of 4.8km of communication line can be extended).

6. Setup
Setup should occur before using the IF-400, to set the Communication speed and Sending/Receiving
switching character, according to the users’ conditions.
If the users’ specification is the same as the default value of the IF-400 (Table 6-1), it is not necessary
to set up the IF-400. Proceed to Chapter “7. Running”.
(Table 6-1)
Setting item Default value
Communication speed 9600bps
Sending/Receiving
switching character
1 character
Setup items and communication line control
After detecting the Start bit of the 1st character upon receiving a data signal from the host computer/PLC,
the IF-400 switches the controller communication line to Sending status.
When data signal from the host computer/PLC stops, the IF-400 sets the controller communication line
back to Receiving status after Sending/Receiving switching time has passed (*).
After detecting the S tart bit of the 1st character upon receiving a data signal from the controller, the IF-400
switches the host computer/PLC communication line to Receiving status.
When data signal from the controller stops, the IF-400 sets the host computer/PLC communication line
back to Receiving status after Sending/Receiving switching time has passed (*).

When communication is not performed, the communication line for both host computer/PLC and controller
are in data Receiving status.
(*) Sending/Receiving switching time is determined by the selection of communication speed and
Sending/Receiving switching character.
(e.g.) Communication speed: 9600bps
Sending/Receiving switching character: 1 character
If 1 character is 10 bits, then Sending/Receiving switching time will be 0.001 seconds (1ms).
Communication timing
The IF-400 performs control within the communication time above. Therefore, if data is transmitted with a
shorter interval than the Sending/Receiving switching time, normal communication cannot be performed.
Set the Sending/Receiving time from the host computer side so that the next piece of data can be sent
after the communication line is switched from Sending to Receiving status.
Turn the power ON
The PWR indicator lights when power supply to the unit is switched on.
Other indicators are unlit. (See Fig. 6-1)
