To check the operation of IC-PW1, I disconnected the PC (DXLabCommander) and checked the connection between IC-7600 and IC-PW1 only. The operation of IC-PW1 is normal even after repeatedly turning the power on and off.
Next, I went through the “Controlling the DXLab IC-PW1” manual, step 1 through step 13, all without fail.
At that time, the INPUT 1 light stopped blinking in step 10. I then turned off the IC-PW1 as instructed in step 11.
When the IC-PW1 is turned on in step 13, the PW1 alert lights up and when clicked, the IC-7600&DXLabCommander and the IC-PW1 frequency are linked. So far, everything is as described in the manual.
The problem occurs when the power is turned off and on again, so I checked the operation in the following numbered order.
1, IC-7600 & IC-PW1 [ON] ? Commander [ON] : IC-7600 and Commander are interlocked, IC-PW1 [uncontrollable] PW1 alert is not lit
2, from the state of 1, IC-7600 & IC-PW1 [OFF] ? IC-7600 & IC-PW1 [ON] : PW1 alert lights up.
3, from the state of 2, PW1 alert Click : IC-7600 and Commander are not interlocked IC-PW1 [Uncontrollable].
Commander [OFF] from the state of 4, 3, ? Commander [ON] : PW1 alert does not light up IC-7600&Commander&IC-PW1 [controllable].
Here, IC-PW1 can finally be controlled.
However, when IC-7600, IC-PW1, and Commander, are turned [OFF], the next time [ON], it becomes [uncontrollable] again.
Is there something wrong somewhere other than the Secondary CAT Serial Port setting in DXLabCommander?
+ No one else who uses Commander's Secondary CAT Serial Port to control their PW-1 has reported a problem, Shige. Powering your PW1 off and then back on does not change the behavior of Commander's Secondary CAT Port. It only changes the behavior of your PW1 -- unfortunately, incorrectly. I cannot tell you why.
+ If you'd like to understand more about controlling your PW1, review this document:

+ It's author - Larry K8UT - was a longtime contributor to N1MM and DXLab, but is unfortunately now a silent key.
