KE2 Therm’s Local Area Dashboard & Alarms (LDA) is the perfect addition to the Refrigeration Network.

When the KE2 LDA is connected to the same network as KE2 Therm controllers, it immediately and automatically scans and finds all KE2 Therm controllers – Ethernet or Serial-ModBus.

Serve as a Permanent WiFi Service Tool

Display a Local Area Dashboard showing controllers connected to the customer’s network

Connect controllers to KE2 SmartAccess customer portal without requir-ing controller upgrades

Send E-mail Alarms to multiple e-mail recipients

View Serial devices in a webpage, make changes to setpoints, and re-ceive alerts via e-mail or text message

366-day data logging when used with the KE2 Flash Drive (see bulletin Q.5.48)

Wirelessly tether to the local network (Wirelessly connect a controller to existing WiFi.)

Guest Mode: Connect wirelessly to the KE2 LDA with no password, ac-cess up to 99 devices.

The KE2 LDA allows customers to locally view all of their controllers in a single view, without a recurring fee. And, additionally, enables customers to access their controllers over the Internet, by functioning as a conduit to KE2 SmartAccess (available for a nominal monthly charge.)

The eth0 IP address and the LAN and WAN links.

LAN - https://ke2lda.ke2.co

WAN - https://ke2lda-406608*(*This is an example only. The WAN link uses the 6 digits of the KE2 LDA’s MAC Address. It will vary for each KE2 LDA).

KE2 LDA’s firmware version in-formation, is also available at the bottom of the page.

Update Available will be dis-played if there is newer firmware available.

For controllers on the network, simply click on the IP address of the controller, to immediate-ly connect to that controller’s Home Page.

Access the Local Dashboard:To access the Local Dashboard, connect to the KE2 LDA wireless SSID or cabled to the LAN. Since it is an Ethernet de-vice, speaking TCP/IP, users can con-nect to it by simply launching their pre-ferred web browser, and typing in the address bar: https://ke2lda - OR - IP address 192.168.50.1

For multiple KE2 LDA’s on the same net-work ke2lda-MAC address will register with DNS.

Example, https://ke2lda-406608 can be entered in web browser when con-nected wirelessly or LAN to LDA or on company network if WAN access is enabled.

This brings the user to their local dashboard.

Once connected to the dash-board, the user will immedi-ately see up to 10 displayed controllers.

Remote Access SetupKE2 LDA provides the user with simple remote access to KE2 Therm’s Smart Access portal, which provides quick and easy, real time access to your refrigeration systems 24/7. No port forwarding. No vpn. All the KE2 LDA needs is a physical con-nection to the network router with a cat 5 cable.

KE2 Smart Access automatically connects to your personal web portal, providing a dashboard of the controllers you publish with the KE2 LDA.

Portal: The portal is the in-ternet address used to access the controllers remotely. This should NEVER be changed with-out directions from KE2 Therm. Changing it may result in loss of remote access.

Check the box to enable Access.

Site: The default Site for all LDA devices KE2LDA-and the last 6 digits of MAC Address. KE2 Therm recommends changing this to something easily re-membered by the person who will be accessing the controllers remotely.
