ACOM Director – ACOM Amplifier Control Software

ACOM600S or ACOM1200S Users – This page applies to ACOM Director Classic which only supports the ACOM2000A, ACOM Director Plus supports the ACOM600S and ACOM1200S (ACOM2000A support coming soon). For ACOM Director Plus downloads please go here, a dedicated ACOM Director Plus page will be added once development is complete.


ACOM Director Classic is a free software package designed to allow the computer control of the ACOM 2000A HF Amplifier.

Version 0.7.1 now includes integration with Logger32 to allow the ACOM 2000A to track the frequency of your radio.

The software is in beta at the moment and is still very much a work in progress, your feedback and suggestions are very much welcome, please contact me here with any comments that you would like to make.

ACOM Director Classic is provided free of charge and you may use the software on as many machines as you like, however I would ask that you not host your own copies for download, but rather link back to this page in order to ensure that anyone looking for the software will always have the latest version available to them.

I am in no way connected to ACOM and provide this software without any warranties or guarantees, you use it entirely at your own risk.

System Requirements

You will require a Windows XP/Vista/7/8/8.1/10 either 32-bit or 64-bit with the Microsoft.NET 3.5 SP1 Framework installed


How do I connect a computer to my ACOM2000A?

There are two ways of connecting your computer to the ACOM2000A HF amplifier


Method 1 – Basic Null Modem Cable

You will need to connect a com port on your computer to the RS232 port on the rear of the ACOM2000A using a basic null modem cable. The wiring for the null modem cable should be as follows

Pin 1 – No Connection

Pin 2 – Pin 3

Pin 3 – Pin 2

Pin 4 – No Connection

Pin 5 – Pin 5

Pin 6 – No Connection

Pin 7 – No Connection

Pin 8 – No Connection

Pin 9 – No Connection

It is important that you do not use a “Full” Null Modem cable with all its pin connections made. This is because the ACOM2000A’s RS232 port does not appear to be a real RS232 port and it utilises the other pins for ACOM’s own purposes. These appear to be undocumented however there have been reports that useage of a “Full” Null modem cable can cause errors to appear on the RCU (With “Microprocessor conflict” being the most common) or could even cause damage to the computer’s COM port due to excessive voltage on the other lines.

Please note that when using this method, you will not be able to power on the ACOM2000A using ACOM Director.


Method 2 – Through a remote power on adaptor

ACOM themselves provide a remote power on adaptor and there are a number of homebrew solutions available on the internet. All of these solutions essentially operate in the same manner, using the RTS & DTR lines of the COM port to switch pin 5 of the RCU connector in order to turn on the amplifier.

You will typically need a “Full” Null Modem cable if you are using one of these devices, however some designs will have the cross over of Pin 2 & Pin 3 built into the adaptor, in which case a regular RS232 cable will be required.


Donations & Support

Whilst I provide the software free of charge, I have been asked by a number of people if I would be willing to accept donations. I have chosen not to accept donations as I feel that this project is part of my small contribution to the Amateur Radio Community. If however you can offer help and assistance in progressing this project, please contact me here
