Wiring connection
The following describes a connection example when two or more TCS-NET Relay Interface units are used.
Terminator resistor setting (See “6 Setting” for the setting method.)
• Set the RS-485 terminator resistor to “120 ohm” for address1 (Relay Interface address SW1=1) TCS-NET Relay
Interface unit, and set to “open” for other units.
• Set the TCC-LINK terminator resistor to “open” as it is set on the air conditioner side.
Shield earthing
• The RS-485 communication cable must be earthed on address 1 (Relay Interface address SW=1) TCS-NET
Relay Interface. Fix the shielded wire of RS-485 communication cable with metal cable clamp and screw it to the
chassis to earth it. The shielded wires must be crimped with closed end connectors on interfaces with address
of other than 1. The shielded wire ends must be insulated and left open.
• Do not connect the shield wire to the terminal block. It should be open and insulated. The TCC-LINK
communication cable must be earthed on the air conditioner.
Do not connect the shielded wire of
TCC-LINK communication cable to
the earth.

RS-485 terminator resistor is set
by relay interface of address
setting switch SW1=1 only.
Set the TCS-NET Relay Interface address with SW1. Assign
1 to C(12) to each address to avoid duplication.
CAUTION: The SW1 setting is read when the power is
turned on. Push the reset switch SW7 after changing the
address.

6 Setting
The following settings are necessary to use TCS-NET Relay Interface.
• SW1 TCS-NET Relay Interface address set switch
When two or more TCS-NET Relay Interface are used, set a different address for SW1 to avoid address
duplication.
Assign addresses in an ascending order.
CAUTION
• Set relay interface addresses according to the air conditioner address table.
For the relay interface whose address SW1=1, perform terminator resistor setting.
• When the SW1 setting has been changed, push the reset switch SW7. The new address setting is read.
• SW2 Test switch
• SW3 Test switch
• SW4 Test switch
Not used during operation.
Set these switches to zero (0) or “all OFF”.
• SW5 RS-485 terminator resistor select switch
Set “120 ohm” only when the relay interface address SW=1, and set “open” for other relay interfaces.
• SW6 TCC-LINK terminator resistor select switch
The TCC-LINK terminator resistor is set on the air conditioner side. Set SW6 to “open”.
• SW7 Reset switch
When performing an address setting with SW1, push this reset switch after the address setting to read
the set value.
