Signal wires
Connection diagram
The shield earth of the RS-485
signal wires should be single-point
earth. Earth the wires on the Touch
Screen Controller.
Set the Digital Input/Output Relay
Interface address with SW1. Assign
1 to 4 to each address to avoid
duplication. You can set the digital
Input/Output Relay Interface address
independently from the TCC-LINK
Relay Interface address or the
Energy Monitoring Relay Interface
address.
CAUTION: The SW1 setting is read
when the power is turned on. Push
the reset switch (SW7) after
changing the address.
CAUTION: Set the RS-485
terminator resistor on the TCS-NET
Relay Interface. No terminator
resistor setting switch is provided
on the Digital Input/Output Relay
Interface.
