Master

/host

The host must be either a

PLC or PC. It is not

allowed to connect both at

the same time.

(RS232C œ RS485)

RS232C cross-connected cable

(prepared by the customer)

Junction

(5-1473574-4 made by AMP)

e-CON connector

(*-1473562-4 made by AMP)

Can be connected

using a terminal

block, instead.

Recommended cables

(Taiyo Cabletech HK-SB/20276xL (m) 2P x AWG22)

Adjust to the master (host).

Controller link cables

CB-RCB-CTL002

(Comes with one junction,

one e-CON connector and

one terminating resistor with

R = 220 : 1/4 W)

Cable for network connection

CB-ERC2-CTL001

ERC3 power supply I/O cable

CB-ERC3P-PWBIO***

Note: The baud rate of an RC controller automatically

switches to 9600 [bps] if it detects a break (space) signal

lasting 150 [msec] or longer from the SIO port.

In some PCs, transmission lines are placed in break

condition when the communication port is not open. That if

such PCs are used, the baud rate of the connected RC

controllers may be set to 9600 [bps] unintentionally.

ERC3-SE

[Refer to Section 3.1 for connection of ERC2]

Caution Make sure to use the common 0 V line

of the 24 V power supply for each

controller (other than SCON).

For ROBONET connection, refer to the

separate ROBONET Operation

Manual.
