USB port hooked with ACOM 2000A

Hi Mark,
will try to get my very old ACOM2000A remotely controlled using DDUtil, but wondering how powering up the Acom is handled? I can leave the main Power on (or use a web controlled AC socket) with Acom on remote site, but how to power it up as I now do with the RCU unit? I understood DDUtil works only after the Acom has been powered up? The RCU unit will obviously need stay beside the linear on remote site?

Pekka,
I've described how to remotely turn on your Acom 2000a in this same thread in a post below. I use this unit. https://www.dxengineering.com/parts/aom-rpon?seid=dxese1&cm_mmc=pla-google-_-shopping-_-dxese1-_...

Hi David,
I found you posting saying have you have a Belkin WeMO Maker set up to momentarily connect 12 volts to the remote power on pin on rear DB 9 on amp. I have a Raspberry Pi which controls relay and can have the 12 V to be connected to Acom for power up. I assume have to use the RS-232 port (not RCU port), but what is the right pin? My Acom2000A is very old (I mean one of the very first ones).
Pekka, OH2TA0 -
It is on the RCU connector on back of the amp (connector that remote units plugs into). Momentary connecting pin 5 to 9 will turn on the amp as long as the amp main power switch is on.

OK thanks. So no voltage needed, just momentary connection with pins 5 and 9, that's clear. And then with DDUtil to actually control (and "see") the amp. My idea is to have the required RS-232 cable connected to from Acom RS232 port to a RS-232 -- ethernet adapter device (a simple and especially a cheap version of Remoterig device) on remote site and then have a control over internet with DDUtil running on PC back home. Let's see...

New ACOM RCU and 15-pin CAT to Flex 6500 CAT-USB
Seems noone can get the Acom 2000A to respond to the commands sent out from a Flex?
I have spent the afternoon trying to get it to work. Cable is a brand new FTDI and it shows up in SSDR. Logging enabled and shows data beeing transmitted. 9pin-15pin as just like Roby (as per Acom manual) but nothing. Very odd. BTW why does Auto-report have to be enabled? Using an USB-USB null modem (for my other amp) will start sending commands with Auto-report disabled.

I am assuming you are using the new style remote and connecting to the CAT port on the remote? Have you tried Elecraft setting instead of Flex? Check baud rate. Dave wo2x0

Dave,
Yes thats what I was trying to write: NEW (black) RCU.
From what I can see, Elecraft is sending the same FAxxxxxxxxxxx; command as Kenwood but at a different baud rate. Have been through all baud rates (and stop bits too) and tried Elecraft, but nothing happens. BTW Flex is only listed as PowerSDR, and nothing there either.
Not sure what to try next... And noone here have reported success either.

When I upgraded my amp to the new RCU I continued to to use the DB 9 on back of amp with DDUtil. DDUtil offered more functionality than just having the amp follow the frequency of the radio. I sold my amp quote a while ago. Dave wo2x0

Hi This is A75GM from Qatar , can i have same way connect to flex 6700 Radio , can i have pin connection from usb side which is Tx and Rx and supply cable0

Hello , Try to use setting TS850 and 9600 baud. This is my setting on Acom that is directly connected to the USB of the Flex 6500. Also, I have Ultrabeam connected to the Flex , without ANY computer. New days I will be more precise and detailed. 73 roby IZ2ODM
