To connect to an Omni IIe controller on a

local network using HAI PC Access,

under Configure >> Network enter the

controller’s IP address:

(i.e. 192.168.0.101)

Local Network

Dynamic DNS

If the controller is connected to the Internet via a dynamic IP address, to locate and communicate with the controller from remote

locations over the Internet using HAI PC Access, you must subscribe to a Dynamic DNS (Domain Name Service). Dynamic

DNS is a service that maps your dynamic (changing) IP address to a static (permanent) hostname, allowing you to access your

Omni IIe controller over the Internet using your static hostname instead of an IP address.

A “client” program (typically provided by the Dynamic DNS provider) runs on a PC on your local network and is used to

automatically update your Dynamic DNS provider with your current IP address. Several router/switch manufacturers have

embedded a Dynamic DNS client into their router firmware. These devices work with several of the Dynamic DNS providers,

including both free and commercial services. These devices are especially beneficial because the router can be powered up all the

time, so the dynamic update is always current and is handled by a single device (the router/switch) in the local network. This

allows you to locate and connect to the Omni IIe controller without having a computer on the local network powered up and

running.
