Hardware, Cabling, Installations / Now RRC 1258 turns on the K3 with OUT0 and a one shot board
« on: 2012-05-08, 01:11:15 »
I've been using a DTMF controller/phone call to turn my Elecraft K3 transceiver on for remote operating with my pair of RCC 1258 boxes. I was looking for a way to use the I/O ports available on the radio side Remoterig unit to do the same task and eliminate the phone call with SKYPE.
I see that OUT0 on the radio side box can be set to go low when the control box connects to it in the I/O menu as a "connect" selection. The only trouble is that the K3 only need to see a momentary closure between pins 12 or 5 and pin 8 on the ACC connector, not a steady closure - that would make turning the rig off via TRX-Manager problematic.
Thanks to an Internet search I found the ELK 960 timer/relay board. It can be set to operate as a one shot circuit with an adjustable time for momentary relay contact closure. Perfect and cheap too - when OUT0 goes low because the boxes are connected the ELK 960 closes it's relay once for a few seconds and the K3 fires up. The circuit board is $29 USD.
The board arrived today and it a couple of hours I had the board cabled up and enclosed in a box and tested. It works as it should once I changed jumper 5 from the stock setting.
Here are a few links:

Anyhow, with the thought that somebody might find this useful, I stuck the information up here. You can probably tell I've been having great fun perfecting my remote station control.
I have retained the DTMF/phone set up as it does control AC power to the whole station as my fail/safe fall back to reset the Remoterig units and the DSL modem/router etc. in the event something (most likely the DSL modem) freezes up.

Hardware, Cabling, Installations / Com Port 1 - ready to tackle
« on: 2012-04-25, 23:26:30 »
I'm trying to get clear on how COM1 is wired, so I can add the next control feature to my set of Remoterig boxes which I'm hoping to be control of a Elecraft KPA500 amp with their utility program.
I think I understand the radio side box is wired so the cable to connect to a device should be:
pin2 ---> pin3
pin3 ---> pin2
pin5 ---> pin5
Yes?
So is COM1 on the control side box wired also like above or straight thru like COM2?
Thanks,

Configuration, RRC 1258 / LP-Bridge and Comm2 on the control Remoterig box
« on: 2012-03-23, 19:18:31 »
I've got my remoterig boxes up and running well. Now I'm trying to get LP-Bridge going to I can share access to the K3's serial port with both TRX-Manager and N1MM Logger at the same time. If I run my installation of LP-Bridge locally i.e. the laptop physically connected to the K3's RS232 port via an Edgeport USB --> serial adaptor LP-Bridge works as expected and is flawless.
However, when I try to use Comm2 on the control remoterig box with LP-Bridge it's tells me it can't find the K3. Any single program I choose to run works dandy. IDEAS?
