Hello ; I've just hooked the CAT port of the (rear 15 P) consolle of ACOM 2000A with USB port trought USB FTDI genuine cable (immediately recognized by flex).
Following instructions about cable (see Acom 2000A manual pag.33) interface (  KENWOOD TS480, TS570, TS590, TS870, TS2000, TS..40 etc.).

Set software as  :

on ACOM 2000A Kenwood new type 19200
on 6500 CAT TX slice 19800 8 none 1 none.

Nothing work, or better...  I see the "command" out from USB cable reading advance  log menu of USB port but nothing change on ACOM.

Where is the mistake? . Thanks  you for any help

Roberto,

My Acom 2000 configuration is in the USB users guide. You must build a specific cable (not a standard serial cable). The cable configuration can be found in the USB manual or on the DDUtil website.

The Acom 2000 works seamlessly via USB on the Flex.

Correct. And if you have the serial CAT connector on the back of the amp it will work fine. I am not using a DB 15 cable or DDUtil.

For CAT control you must have the new style color remote and buils a 15 pin to 9 pin cable that goes from remote to usb to serial adapter which plugs in radio.

The db 9 on back of amp only talks proprietary connunications and not CAT commands.. you can connect a custom cable from back of amp to PC and use DDUtil to control amp and have it communicate to the radio.
More info on DDUtil control of 2000a here http://k5fr.com/DDUtilV3wiki/index.ph...

Thanks Dave for your suggestion but I already had connection through DDUTL. It works fine. What' Im'trying to do is use a direct connection using USB cable.

Elmer,
Thanks for suggestion but it continue do not works I just clear connection between pin 3-4 as descrived on "kenwood" cable on acom maual and leave :

DB9 5 -->5 db15 (acom cat connector
DB9 3...>4 db 15(acom cat connector)
DB9  2-->1 db15 (acom cat connector

and shield of course

Where is themistake

Thanks

Roby,

Here are the DDUil hookup notes I'm using from the DDUtil Yahoo Group. It works perfectly. Where is says DDUtil config just configure the Flex USB per their manual.
Setting up an Acom 2000A with DDUtil
Acom 2K Setup
• To connect the Acom 2000A to the Flex through DDUtil you need a "basic" RS-232
DB-9 male to female null modem cable. This cable uses only three wires. Pin 2
to 3, Pin 3 to 2, and Pin 5 to 5.
• Connect this cable from the RS-232 port on the back of the amp (not the
connector on the remote) to a com port on the PC.
• DO NOT use a full, store bought, null modem cable as there are other pins in
the RS-232 connector on the amp that are not used for PC communications.
DDUtil Setup
• Download the latest version of DDUtil and install it.
• Click Setup from the menu bar to open the Setup form.
• On the Amps tab select the PC com port you will use for the Acom and select
1200 baud, then click Enable.
Note: Do not try to use any other baud rate besides 1200 setting.
• It is recommended to use the Auto Drive feature of DDUtil to automatically set
the power output per band so when the amp is in operate the radio power is
adjusted automatically for the band the radio is on.
• Make sure Amp 1 is selected and check the bands you want to use the amp on.
• In the Options group, select the options you require based on your needs. A
good default setting to begin with is BOBC and Amp Follows DDU PTT checked.
Note: See the Auto Drive wiki article link above for Options descriptions.
o BOBC forces the amp and DDUtil to go to standby on band change. This is
done for safety as it allows you to verify SWR before bringing the amp
on-line.
o Amp follows DDU PTT allows you to click the OPER (green)/STBY (yellow)
button on main DDUtil screen to toggle the amp between operate and
standby. When in standby it also disables the TX1 keying RCA port on the
Flex.
• Select the Enable check box to activate the Auto Drive feature.
• A window will appear on the PC desktop labeled A2K. This window is your
interface for controlling the A2K from DDUtil.
• Connect an RCA (phono) cable from the radio’s TX1 connector to the Acom Key-In
(PTT) connector.
Notes:
1. DDUtil uses the TX1 connector for Amp 1 and the TX2 connector for Amp 2 for the PTT key lines. 
Setting up an Acom 2000A with DDUtil
Operation
• Now turn on the Flex and you should see frequency and mode appear in the title
bar of the DDUtil main window.
• Turn on the main power switch on the Acom 2000A amp.
• On the Acom remote console, push the red On/Off switch to power on the amp. In
the DDUtil Acom control window the Acom 2K power button should go green and
ON, the OPER button should be pink and say WAIT while warming up.
• Once the amp is warmed up, click on the yellow STBY button in the DDUtil main
window and it should go to OPER and the amp should also go to operate mode and
band change to the proper band.

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-_...

Please excuse my ignorance David, but what is the "new style color remote" you keep referring to?  can you include a link to one of these things?  Thanks.

There are two different remotes for the Acom 2000a. One is monochrome display and does not offer key in, key out, or CAT connection. Using that remote the only option is to use DDUtil to control amp with three wire null modem serial cable from back of amp to PC.

The new remote has color display and extends key in & out from back of amp to remote and also features a “CAT” connector which supports Icom CI-V, kenwood old & new cat protocol, Yaesu and Elecraft protocol.

Here are pictures of how I have my Acom 2000 hooked up and working perfectly. I'm using an FTDI cable wired as per my description above connected to the PC port on the back of the amp. Here is the picture: The center cable is connected to the Flex.


The RCU is connected using the Acom supplied cable. I am NOT connecting the FTDI cable from the Flex directly to the remote controller but only to the rear of the amp.


Again, the pins are wired per my post above. I can assure you this works perfectly.

Hi Dave , really strange. I have exactly the setting showned by you ; new  RCU , cable DB15/DB9 , setting on USB , genuine FTDI but NOTHING works...Just Auto report is enabled (it doesn't matter I think) .It could be a matter of Flex 6500 software release ? I have 1.10.16...

Pleading ignorance and very little knowledge and and hoping it is a typo, I saw in your post,
"on ACOM 2000A Kenwood new type 19200
on 6500 CAT TX slice 19800 8 none 1 none."

Don't the baud rates have to agree?

It is called fat fingering as I lay here in rehab facility.
(Or the meds)

Both should be 19200.

Good catch Brad!

1.10.16 supports USB cables. Send a picture of the USB cable setup screen.

I no longer own the Acom amp so cannot Test it here.

Everything looks correct. I do not know why it is not working. Since I no longer have the Acom and I used the rear connector of the amp and DDUtil I am out of ideas. 

Maybe someone else reading this that has the Acom 2000a connected to the CAT port on the amp can give some input.

One last idea. If you made the DB15 to DB9 cable yourself, try reversing pins 2 & 3 at the DB 9 in case you have TxD and RxD reversed.

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).

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,
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.
