Re: [Elecraft] band data from the RS232 port while using the USB cable?
Steve, I am not familiar with the Acom amp and its needs, but if it needs 4 discrete band data lines, those are available on the ACC connector. See the K3S manual for the pins. The only lines on the RS-232 line (or USB) are RXD, TXD and Signal Ground, and band data is present on the communications line when data is flowing because of communications with something like a logging program. 73, Don W3FPR On 9/12/2017 3:34 AM, Steve Steltzer via Elecraft wrote: Brand new to the K3S.

Re: [Elecraft] band data from the RS232 port while using the USB cable?
Steve, >Apparently when you select USB in the menu, it shuts off the RS232 port? Not exactly. When using the USB port for CAT control of the radio, the RS232 (RJ45) port becomes a listen-only CAT echo of the responses sent by the K3S to the USB port. I am unfamiliar with the Acom amplifier's requirement for band info, but your amp will track K3S band data under the following conditions: - A conventional logging program is polling the radio on the USB port for band and frequency (which would result in K3S CAT responses emerging from the RS232 port) - The Acom is satisfied just hearing that CAT info (IOW - it does not generate it own queries and require responses. The SteppIR controller operates similarly ) -larry (K8UT) -Original Message- From: Steve Steltzer via Elecraft Sent: Tuesday, September 12, 2017 3:34 AM To: elecraft@mailman.qth.net Subject: [Elecraft] band data from the RS232 port while using the USB cable?
