I do not see where you turn on your computer.

In addition, you say you are turning on and off your 7600 power.? Do not turn on or off your 7600 with the switch on your power supply.? Turn on your power supply first, then push the power button on the 7600 to turn on the 7600.? Turn off your 7600 with the bower button on the 7600 first then turn off your 7600’s power supply.

?

Also:? Once the PW1 is connected to the Mains AC power, the PW1 is always on and asleep.? The power button on the PW1 control panel turns on the PW1 ability to amplify the radio signals.? In addition with the Accessory cable connected between an Icom Radio and the PW1, then turning on the Icom Radio will place the PW1 in stand by and allow the Icom Radio to make antenna selections and allow the Icom Radio to operate “barefoot” through the PW1.?

Caution with low serial number PW1s serial numbers below about # 1030 will not operate in standby.? [I don’t remember the actual serial number, check further if it is below 1050.]

?

Here are some diagnostic steps to help see what is happening:

With the PW1 off, disconnect the PW1 to 7600 accessory cable also disconnect the PW1 CIV cable. Turn on your computer first then turn on your IC-7600.? Check to see that you can control the 7600 with DXLabs.?

If this does not work you need to fix your Commander 7600’s Configuration. ?Check the CIV speed settings and address for the 7600 primary port.? And while you are there check the secondary port for the PW1. ??In Commander’s Configuration you need to have se same speed and CIV address in both the primary and secondary Ports—see:

?

If you can do the previous test, shut down the 7600 with the 7600 power button.? Connect the 7600 to PW1 accessory cable and CIV cable.?

Leave the PW1 alone do not push the PW1 power ON button.? The PW1 will now be in standby mode.?

Can you now change bands on the PW1 by changing bands from the 7600 and/or the DXLab applications?

?

If the first or second test fails. You will need to resync your PW1 to your 7600 radio as described in the PW1 manual.? You need a direct PW1 to 7600 CIV connection to do this—do not use the computer CIV connections in this PW1 to 7600 Sync operation.?

?

Until you can control the PW1 in standby you do not have a reliable CIV between your 7600 and PW1.? And you will not be able to reliably use DXLab and commander to control your PW1.
