- Automatic antenna selection
Webswitch 1216H is also possible to use for automatic antenna selection. When using the Webswitch for antenna selection it should be connected to the Transceivers CAT interface, today it supports Kenwood and Yaesu FT-2K,5K,9K CAT protocol and ICOM CI-V. You program which relay you want to be activated for each band via the internal WEB interface. You can also program the same relay to be activated for more than one band, practical if you use multiband antennas. It’s possible to activate different relays for different band segments which means you can have one antenna for the CW part and another for SSB. It’s also possible to combine the automatic function on some relays with the manual function. The Webswitch either asks the radio about which frequency it’s using, or just listens to the commands sent from the radio, which means that it works without HRD or other PC software. You can also connect two Webswitches together to get 10 relays altogether. Please be aware of that there is no HF-relays in the Webwitch, use external coax-relays or control a existing antenna switch. Another example is control of 4-SQ COMTEK BOX to change beam headings etc.
The configuration of which radio is used is done here(parameter Function type).
The configuration of frequency band segments and relays used are done here.
To activate the function for Kenwood or CAT protocol set Function type to Kenwood or Yaesu. For ICOM CI-V set Function Type to ICOM if you use the Webswitch standalone with the radio. If you use it together with a PC software (ex HamRadioDeLuxe) set Function Type to ICOM no TXD then it will only listen to the serial data sent between the PC and the radio. The Kenwood (FA/FB), no txd, Kenwood(FA), no txd and Kenwood(FB), no txd modes also only listen to the serial data. The risk for unnecessary collisions on the serial bus eliminates this way. When used with ICOM a CI-V address also must be set witch should match the one in the radio. The Webswitch serial port parameters can be set under Serial settings.
There is also support for R&S XK2000. Set Function type to R&S XK2000 to have the Webswitch poll for frequencies, or set it to R&S XK2000, no txd if it only should listen.
On the Relay Settings tab you can set describing texts to the different relays:
The schematic diagram below shows how the WEB-switch is connected to the ICOM CI-V interface:
The schematic diagram below shows how to connect to Kenwood or Yaesu CAT interface with a RS-232 port. You can use the RS232/TTL Adapter 1216R (available from the web shop) or make one by yourself:
If you use HamRadio Deluxe Pin 2 should not be connected in the D-sub, only pin 3 and 5 should be connected in parallel with the cable from the HRD PC. In this case the WEB-switch will only listen on the traffic between HRD and the Radio.
The picture below shows the connector where the CAT-cables should be connected. (To the white AMP-connector)
Connecting two Webswitches together for 10 relays.
If you need more than 5 relays for the antenna selection you can connect two Webswitches together. The second switch will act as a slave, and no setting are needed in it, all settings are done in the first Webswitch. Set relay extension master in the Advanced menu to Yes to activate the function. After reset, fields for relay 6-10 will show up. Remember that both units need firmware v1.10 or later.
But first connect them together by connecting a wire from connector 9 (Bus-A) to the same connector at the second Webswitch. Also connect a wire from 10 (0V) to the same connector at the second Webswitch. Both Webswitches also need to be powered as usual.
The Set relays page will then show 10 relays. Note that if all the ON and OFF buttons for relay 6-10 are gray then the communication between the master and slave Webswitches doesn’t work.
At the Set relays tab all 10 relays will show up
