I will be using an ACOM amplifier within a few weeks (depends on how bad the supply crunch is). My radio is ANAN 7000 DLE MKII (Black Edition).
The ACOM manual states (this is in regards to the "KEY-OUT socket" on the back apron of the amplifier):
"The KEY-OUT socket provides an extra control signal from the amplifier to the transceiver. It could be used to improve the transmit/receive (TX/RX) switching safety.
NOTICE:
KEY-OUT is a low-power open-drain output, make sure that the signal voltage coming from the respective transceiver connection does not exceed 50 VDC (open circuit) and the closed-circuit current is below 20 mA.
If your transceiver has a suitable input that disables transmission unless grounded externally, we recommend that you connect it with a shielded cable terminated in a Phono (RCA) connector to the KEY-OUT socket of the amplifier.
ACOM will operate normally with KEY-OUT unconnected if your transceiver has no such input........"
Am I being overly cautious in thinking that I may want to run a phono cable between the KEY-OUT socket of the ACOM and "Connector #16, Digital-IN" ("transmit inhibit") of the ANAN? In theory, this connection is NOT needed, but I would think having the cable there would be "extra insurance."
Would appreciate comments and thoughts on the above!
Best!

Re: Interfacing with ACOM amplifiers (still awaiting comments)
I can’t believe I am the only ANAN 7000 DLE MKII user who will hook it up to an ACOM amplifier
Is what I was suggesting (using two cable between the ACOM and the ANAN) too elementary a question
Would appreciate comments!

Re: Interfacing with ACOM amplifiers
Good morning "JJ",
I've been running my 7000DLE/ACOM2000A combination for quite a while.
DDUTIL interface works ok.
I never tried to use "Key Out".
Normally I do not write replies which cannot be helpfull for the starter of a topic.

Re: Interfacing with ACOM amplifiers
Guten Tag Volker!
I appreciate your response.
Perhaps I email ACOM on this. All I am wanting is extra “safety” when using the ACOM1000 with the ANAN. Surprised at not having gotten many responses on this.
Best regards,

Re: Interfacing with ACOM amplifiers
I think you are over thinking it.
Re: Interfacing with ACOM amplifiers
You are probably right. Doug - W5WC - emailed me to the same effect.
Below, a direct quote ( I don’t think he minds me including it here) on my email where I specified that I am using the ANAN 7000 DLE MKII Black Edition.
“Just my initial quick thoughts on the matter. Yes, you’re being overly cautious. I think that the Digital-IN requires an external ground to inhibit the tx. I had added a reverse switch in the software but the firmware developer hardcoded it in the firmware. Maybe it would add some latency if you’re on CW.”

Re: Interfacing with ACOM amplifiers
ACOM 1500 & ANAN 7000 DLE MII “BLACK BOX”: No KEY OUT. They work great together. I do use an Ameritron Amplifier Transceiver Keying Interface ARB-704
