Is anybody out there who operates the ACOM2000A with the new RCU? In a setup, the 2000A with the old rcu works perfectly together with the 1216H. When swapping the rcu to the new model, there is no power up possible. Is there any difference in the power-up design between new and old RCU? In the old RCU, the power-up was initialized by closing pin 5 and pin 9 of the RCU-cable. That doesn't work with the new RCU.

Any ideas?

Just downloaded and installed the Iphone-App for Webswitches, works great, just brush up your webswitch to the newest firmware release, install the app on your Ipad or Iphone and it works. Congrats and thanks to the developpers!

Hi Jan

Any chance to build the possibility to use the relays of the webswitch as time-relays or pulse switches (e.g. relay open or closed) for a definable time range? Would be a great feature to reset external devices and to substitute push buttoms on some devices.

The remoterig webswitches are very handy items. It would be a great feature to be able to configure the relays also for a pulse-mode with definable duration. Some applications need pulse switches and you have to solve the problem with external switching devices.

After some experimenting I have two new items running via com1 of the remote-rig boxes (old mark1-model, but should also work with the recent model):

Elecraft WN2-Wattmeter: straight forward rs232-cable at control site, 0-modem-cable at remote(radio)-site
com1-settings: mode 3, 9600 Baud, 1 stop bit, no parity on both boxes

Easy Rotor Control Interface (for details about that excellent and cheap antenna rotor interface see straight forward rs232-cable at control site, 0-modem-cable at remote(radio)-site, com1-settings: mode 3, 9600 Baud, 1 stop bit, no parity

To explain the basics in a few words:

both of the  remote-rig boxes com1 act as dce (data communication equipment). dce and dte (data terminal equipment), e.g. a pc can be connected via straight forward RS-232-cable. To connect a dce to another dce, you need a 0-modem cable (at least pin 2 and 3 crossed). Most "radio amateur toys" like wattmeters, antenna rotors or a lot of transceivers are configured as dce. That's the reason why a straight forward cable is needed at the control site and a 0-modem cable is needed at the remote site. 

Finally a working wattmeter to monitor a remote station and a good serial rotor interface for azimuth and elevation!

May be this is of interest for some users, saves hours of trying and soldering different cables :)

Hello Mike

For the next release of the webswitch-firmware my proposal:

one ore two relays should be definable as pulse switchers with configurable switching time. This is necessary for some applications where you have to simulate a pulse switching, e.g. switch on and of an acom linear amplifier or to trigger an antenna tuner.

Any chance to get this feature in the next release?

There is temperatur input at the web switch. Is it also possible to use that input for detecting an external voltage eg. 12V to check the status of an external voltage?
