WEB-Switch 1216E / Automatic Antenna switch


The Webswitch 1216E are discontinued and replaced by 1216H

WEB-switch 1216E is a remote controlled switch with 5 relay outputs 230V/16A which can be controlled independently via the built in web server from any computer connected to the Internet. It can also be configured as a automatic antenna switch connected to the radios CAT interface . It's perfect suited for controlling coax relays, switching the Rig on/off or maybe the Power Amp. No PC is needed like in USB switches everything is built in the box, the WEB-switch is connected directly to the local network. If the WEB-switch is located behind a NAT-router you need to set up a port forwarding in the router to the WEB-switch to make it reachable from the outside. The WEB-switch default IP is and the built in WEB-server is using port 80. IP-address can be changed via ARP with the small PC-software called IP-setup which you can download on this page. IP-setup can also be used to update the firmware. An important  feature is that the switch is remembering the Relays statuses even after a power failure. The relay statuses is indicated by LED:s. The Settings is protected by a password.


The WEB-Switch can also be used for remote temperature ( more info) checks or for temperature control if you connected temp sensor (Dallas DS18B20) by your self. The Switch fits into a standard DIN-rail system (6M). There are lot of cheap DIN-boxes which can be used for outdoor installations.

Down below follows more info about the WEB-Switch.

Above: First >age of the WEB-Switch  Internal web server. In the example it has the IP-adress To the left there is hyperlinks to other internal information pages.

Above: Behind the Link "system" you will find information about the unit. Firmware versions, IP-addresses etc.

Above: On the webpage behind the link "Set Switch" you can control the relays, the individual statuses is indicated by the green colour. A short describing text can be set to each relay. Be aware of that you need to be logged in to control the relays.

Above: The menu for editing the describing texts. Be aware of that you need to be logged in to editing the texts.

Above: behind the link "Temp" you can check the two temp sensors if they are connected. You can also set the wanted temperature if you use the WEB-switch for temp control.

Above: Behind the link "Change data" you can make some initial settings. Identity <>is the text which is shown on top of most internal web pages. Function type select how you want to use the WEB-Switch. 0= All relays are controlled manually. 1= Relay 1 will act as soft temperature control. Cycle set how long the total control cycle is, in slow systems like a house you may use 15-20 min, in a small cupboard shorter may  times fits better. If cycle time is set to 0 the cycle time is set to 20 s. If you just use the WEB-Switch just for reading temperatures set cycle time to 0 to get shortest possible update time.  In the box "Http port" you can change the port for the Internal WEB-server from standard port 80. It can be convenient in combinations with routers and port forwarding. Be aware of when you change IP-address with IP-setup the http port is always set back to 80. I<>n the box "New password" you can change the password which is needed to make setup changes or control the relays. The password will change back to default "1111111" when you change IP-address with IP-setup.

Above: The web-pages for reading the analogue input. The A/D <>converter has 10 bits resolution. 5,0 V input = 1063 or 360 deg. 0 V <>gives 0.

Above: The Login page, fill in the password and click "Login". You do not need to login again until you change your IP-address.

The Software IP-Setup is used to change the IP-address of the WEB-switch. There is no other user Interfaces so we need to use the TCP/IP Network to set the IP-address. It's done from the IP-setup with a encapsulated standard protocol ARP. When you start up the program ( no installation needed) you will see the dialog below. When you enter the Serial number of the WEB-switch, IP-Setup calculates the MAC-address <>automatically. The Serial number is available from a sticker on the bottom of the switch. Enter the network parameters on in resp. box. To make the function more secure you need to program it within 60 s from restart. That's why you always should disconnect the WEB-Switch from power for a few seconds before pressing "Apply" to confirm the new settings.

The IP-Setup software only works 100% with Windows XP.

If the programming succeeded the box below will show up.

Use your Internet browser to connect to the new IP-Address.

If you will use the WEB-Switch for remote control over the Internet it will most of the times be placed behind a NAT-router, witch means it will not be directly accessible from the Internet. Fixed IP-address is also not very common witch is an other problem. The most common solution to this is to use port forwarding in the router and register a DynDns account (free).

The port forwarding <>makes it possible to setup the router in the way that a "call" from outside to port 8001 is mapped to the Inside IP-address used by the WEB-Switch and to port 80 for example. If the router does not support port translation it's possible to change the http port number in the WEB-Switch. As an example you can set the WEB-Switch http port to 8001 then the router can do a straight mapping ( most of the Netgear routers only handles straight mapping).

At www.dyndns.com you can register a account, witch gives you a dns host name witch can be used for accessing the WEB-switch from the Internet. The router at the remote site must also be programmed to send the IP-address to DynDNS. When you have done that a call to the WEB-Switch can look like the example below.

Almost every router from the commonly used brands supports the DynDNS functionality ( even the cheapest ones).

Good luck with the remote control....

Updating the firmware (software)

The internal firmware can be updated via the IP-Setup software. The .BIN file should be updated first and after that the .ROM file. Download the files to your computer (Desktop) and start the IP-Setup. Select the files Update the BIN file first by clicking on the  "Update" button, when it's done, update the WEB/ROM file by clicking the associated button. Before Updating check that the right IP-number is shown in the "Current IP address" box. If not go to the "IP-address" dialogue and change to the correct IP-address. Updating firmware is only possible when connected to the same LAN, not over the Internet.
