Built-In Ethernet Port
The built-in Ethernet port (J6) allows a device to connect to the HMS 1100 controller via a network (i.e. Ethernet, Internet) using
a secure, encrypted communication link. The Ethernet port transports HMS application-level packets containing HMS-Link serial
protocol messages over IP. The controller supports 3 unique client “sessions” which means 3 devices may actively be connected
and communicating with the controller simultaneously over the Ethernet port.
Controller IP Address, Port Number, and Encryption Key
The controller’s local IP address and port number set the local network parameters for the HMS 1100 controller. The encryption
key is used to establish a private, secure connection with the connected device.
These Setup items can only be assigned and changed from an HMS console. These items can not be assigned or changed via PC
Access; although the IP address and port number may be viewed via PC Access - See Set Up Miscellaneous.
HMS 1100 Ethernet Connections
Use a standard network cable to connect the controller to a hub, switch, or router. Use a network crossover cable when
connecting the controller directly to the NIC card on a computer.
When connected to a switch or router, port forwarding must be configured. Port forwarding sets up public services on your
network. The HMS 1100 controller listens for all IP/UDP communications addressed to it on the specified UDP port number.
The router will forward all communications on the specified port to the HMS 1100 controller.
Connecting to Network via PC Access
To access the controller over the network via PC Access:
1. Open an HMS 1100 account file.
2.
Click Configure >> Network.
If you are connecting from the local network, enter the controller’s IP address under “Network IP Address or
Domain Name”.
If you are connecting from the Internet, enter either the public IP address (the way to reach your local network via
the Internet) or domain name (e.g. www.onqtech.com).
3. Enter the port number that is configured for the controller.
4. Select the Encryption tab. Enter the two part encryption key as it is displayed on the console.
5. Select OK.
6. Click Connect >> Network >> Connect. PC Access should change from “Off-Line” to “On-Line”.
The “Modem” item on the main menu has been replaced with the “Connect” item. The submenu under “Connect” then allows
selection of “Modem”, “Serial” or “Network”. When an account file is opened, the connection type will default to “Serial”.
