Can One Computer Run Both Niagara R2 and G3 Serial Tunneling?

[Product_Support]

Issue

Is it possible to configure a single computer to perform both Niagara R2 and Niagara G3 serial tunneling?

Product Line

TAC IA Series

Environment

• Niagara R2 Serial Tunnel Client
• Niagara G3 Serial Tunnel Client

Cause

Running Niagara R2 and G3 simultaneously on the same COM port causes conflicts and prevents proper operation.

Resolution

Yes, a single computer can run both Niagara R2 and G3 serial tunneling services.

• Each version installs its own Windows service, allowing them to operate concurrently.
• Important: They must use different COM ports.
• If separate COM ports are not available, only one service can be active at a time. Stop the other before starting the desired service.
