4-4-3 Setting for TCS-NET relay interface
The following settings are necessary to use TCS-NET Relay Interfaces.
• SW1 TCS-NET Relay Interface address set switch
When two or more TCS-NET Relay Interfaces are used, set a different address for SW1 to avoid
address duplication.
Assign addresses in an ascending order.
• 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.

REQUIREMENT
• RS-485 terminator resistor select switch SW5.
Set "120 ohm" only when the TCS-NET Relay Interface address SW=1, and set "open" for other
relay interfaces.
• The Main BUS terminator resistor is set on the air conditioner side. Set SW6 to "open".

CAUTION
• SW6 Main BUS terminator resistor select
switch
The Main BUS 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.
