Hardware, Cabling, Installations / Re: Power Requirements, RRC-1258 (Control Side)?

FYI.

I have measured the current consumption of the K3/0-Mini and RRC-1258 box when connected and operating. Battery was providing 13.2 V. 

RRC-1258   110 mA
K3/0-Mini    200mA

Thanks Mike!

I see that in the RRC-1258 manual, 'Rev. A40 - 2019 sept 18' page 18, but specified for IC-706, TS-480, and 'RS-232'

My use is with K3/0-Mini, which is powered separately. Would the 'RS-232' note be applicable?

Is this the most recent manual?  Am I missing something?

Hardware, Cabling, Installations / Power Requirements, RRC-1258 (Control Side)?

« on: 2025-09-07, 21:54:45 »

Has someone here measured the power (i.e. current) requirements for the RRC-1258 box? The manual does not say, and only mentions that a 1A supply is included. I cannot imagine that the box requires a full 12V 1A supply.

I'm assembling a portable/transportable terminal, and trying to get an idea of how large a battery I should include, and how long it might last.

Thanks!

Good to have confirmation that the pot is 10k linear.

I posted a photo of the apparently-failed pot in another post, and have added it here as well.

Hardware, Cabling, Installations / Replacement Part: RRC-1258 CW Pot?

« on: 2025-06-17, 23:08:18 »

The problem I had with adjusting CW speed on my RRC-1258 MkII appears to be a failed potentiometer, which shows physical signs of damage.

It is marked "103A, 437C". See the photo.

Can someone here identify a replacement part?

Hardware, Cabling, Installations / Windows 11 / Setup Manager: Driver Will Not Load 'ftvspenum.sys'

« on: 2025-06-16, 08:52:13 »

I installed the Microbit Setup Manager software (version 2.06) on my Windows 11 laptop. During the installation, my screen was filled with eight instances of a popup that said:

       "A driver cannot load on this device, Driver: ftvspenum.sys"

The same popup now occurs whenever the laptop is booted.

The Setup Manager seems to work OK, but I am having some issues with the RRC1258 (CW pot not working, IP address not always retained across power cycles).

Anyone else have similar experience with Windows 11 and Setup Manager WRT 'ftvspenum.sys'? Suggestions?

Hardware, Cabling, Installations / CW Pot Not Working?

New installation of a recently-purchased used RRC-1258 MKII box. Cloned the configuration from the remote terminal I've been using for several years. Everything seems to work, but the CW Pot does not change the CW speed. Paddle is plugged into the RRC1258 box, and CW is sent well, but only at a fixed speed.

CW speed seems to be fixed at whatever speed is entered in the 'Speed pot min wpm (5-99)' field of the 'Keyer Setup'. 'Speed pot max' is set to 40 wpm.

If I start N1MM+, it initially correctly shows the speed currently configured as the minimum wpm (and being sent by paddle), but it does not affect the actual speed of the keyer when adjusted up or down.
