You should be able to change Parameter word #39 to 9600 if using channel 1. Be sure to wait for about 2.5 minutes for backup to occur automatically and the power down including the breaker for 1 minute to let the RS board reset properly.

I change the parameter #39 to 9600 and backup (F7),=> restarted ... Everything has not changed...works only at 4800

Then I would suspect that you are not using channel 1. Check your word#43 parameter to see what it is set to. I believe that is designating which port DNC will use. If 0 then using channel 0 and so forth. If 0 then try setting baud on word#6. Channels 2,3,4 are Word 40,41,42. Change the appropriate one as described before.

I did but the system still doesn't work at 9600.. (#6 9600, #39~42 9600, #43 0)

Did you follow my exact instructions about powering down with breaker off for 1 minute?

If you did then go to the parameter mode on the machine and type in CMPS and tell me if some “magic” DNC parameters open up.
