Hardware, Cabling, Installations / FT-897 RX/TX data via AUX/MIC

« on: 2011-09-29, 23:09:23 »

Hi

I have a problem getting the data communication to work with my FT-897.

Studying the diagrams in manual I have setup the AUX/Mic connector on both RRC units to put TX/RX data on Pin 1+2 by two additional jumpers on the "straps socket" (#3:RXD and #6:TXD).

I setup my FT-897 to put TX/RX data on pin 1+2 on front panel mic connector.

I have verified that it works on the RRC-Radio and data is transferred to RRC-Control (using a separate RS-232 cable on COM2 : but data seems not to be present on the AUX/MIC terminals ?

From the manual I would expect that it was possible to get the TTL levels on the AUX/Mic connector as well as on the TTL conector - but is this somehow disabled on the RRC-Control unit ?

Hi

I got it working !

The FT897 has TTL level CAT interface, and I found a diagram for the AUX/MIC connector in the manual that clarified things. The AUX/MIC and the TTL connector uses the same path for TXD and RXD (i.e. COM0), so either can be used.

The strapping must be expanded with two more wires so that RXD and TXD from RRC have a path to the microphone,

Using the CAT interface in the microphone connector makes cabling more simple, and it also frees up the CAT/LIN/TUNER connector on the back for a linear amp or tuner as a bonus :=)

At the control site i have tied COM0 and COM2 together and connected the PC to COM2 with a straight (2-2 + 3-3) COM cable to get the levels converterted to ±12V.

Hi

Is the possible to use the RXD/TXD (COM0) on the AUX/MIC for radio CAT interface microphone using a Yaesu radio (program mode 3)?

I setup my FT-897 to use send RXD/TXD via microphone plug (pin1+2).

From other radios in the manual (that have CAT interface via AUX/Mic), I figured out that strapping 8->2 and 2->1 on PCB would connect data interface to the Radio-RRC.

But it seems not to be working...

Hi  Mike

Thanks for the help ... the straight keyer is now working ...

Hi

Ok, I will try this... must the paddle be activated in order for this to work ? I would like to free up a least one of the INx on control-RRC to be used as a antenna switch ...

Hi

How should the Radio RRC be programmed if I only want to use a straight key interface at control site ?

I wired the straight output to radio to OUT2 on I/O port
I only get it working with Out2 mode set to I/O, but will there be a difference in the keyer timing using "I/O" vs "keyer" as the mode ?

Hi

You can set one of the radio outputs on I/O port to be activated when the SIP connection is active. With this control signal you can drive a relay that turns the radio on/off. Be sure the relay can handle the current and voltages involved.

I build a small box that powers off 220V to the radio when theres no SIP connection.
OUT0 drives a small reed relay that drives a much larger relay (able of switching 250V / 10A).

You can use the same signal to drive another relay in order to switch off the antenna when the radio is not used.

Hårdvara, Kablage, Installationer / FT-897 CAT via mikrofon plug

« on: 2011-03-28, 22:55:21 »

Hej

Har studeret dokumentation på RRC-1258 Radio, og så vid jeg kan se er det muligt at koble CAT forbindelsen direkte til AUX/MIC pluggen (og dermed frigøres stikket på bagpladen til f.eks.tuner eller Amplifier).

FT897, Menu-059 sættes til "CAT", dermed ledes RX/TX Data til microfon stikket på forpladen (RJ-45 Front MIC connector)
PIN-1 : TXD
PIN-2 : RXD

I 1258-radio strappes internt på PCB følgende to ekstra ledninger:
PIN-3: RXD  <---- MIC/AUX: PIN 1 (FT-897 TXD)
PIN-6: TXD  ----> MIC/AUX: PIN 2 (FT-897 RXD)

Mit spørgsmål er: Hvilket signal niveau anvendes af RRC-1258 (TTL eller RS323 (12V)) når man kobler sig ind på RX/TX-data på AUX/MIC stikket ?

Hejsa

Har haft samme problem med en carrier hver 30 KHz ... det viste sig at være en defekt netværksswitch der var årsagen ...
