General discussion forum / Re: FT-847 with RRC-1258 MarkII: RS-232-problem
« on: 2011-03-01, 13:51:44 »
Hi, Staffan,
thank you for your mail and your patience.
By the way (to prevent misunderstanding):
I feed my "Control-box" at COM1 from my PC and I try to control my FT-847 from COM1 of the "Radio-box". Speed: 9600 baud (also on FT-847).
Until now I do not use COM0.
My settings:
1) Control-box:
Program mode: 3 - FT 8x7, FT 1000x
Sip password:
Sip contact: 192.168.123.228
Auto connect: Yes
Audio quality: 2-Linear 16 bits 8 kHz
Codec out gain: 255
Codec inp gain: 16
Codec inp. HPF Hz: 163
Codec inp preamp: No
COM0 baudrate: 9600
COM0 data bits: 8
COM0 stop bits: 2
COM0 parity: 0 - off
2) Radio-box:
Program mode: 3 - FT 8x7, FT-1000x
Sip password:
Audio quality: 2 - Linear 16 bits 8 kHz
Codec out gain: 255
Codec inp gain: 0
Codec inp. HPF Hz: 163
COM0 baudrate: 9600
COM0 data bits: 8
COM0 stop bits: 2
COM0 parity: 0 - off
I think our differing Codec parameters are not important for the control of the FT-847.
I discussed my problem with some hams and they did see a possible cause of my problem within the open definition of the RS-232 connections:
are all 0/+5 volts or are there also +/- levels. I am looking now for an oscilloscope to see what happens within the chain between PC and FT-847.
Thank you again very much and best regards.
