We bought few AMPs to try. 2xK3 DSP; 2xK6 DSP;
S/N: k3 30001 30002; k6 23213 22926.
I found some informacion on AMP's after software update:
KFRNT:4.0.2-87
KCTRL:4.0.2-87
KDSP:4.0.2- 2000
KAESOP: N/A
Version: 3.26.3
Is that is right wersion for this AMP's ?
COM port is working and setted right. I event tested my USB/rs485 with sending DMX signal and moving 4 units of Martin MX-10 scaners (lighting)

And I even try to set teminator (resitor) 120 Ohm 1/2 wat power at the last amplifier.
I even made Tester Rs 485.

So i found that then I reconect adapter - Armonia firts time see it (by pressing TEST button) (Diod tester OK). then I press second time test - Armonia program writes Error.
I am thinking maybe settngs of Rs485 is not right setted? What parameters i have to set? (Speed and so else...)
