[ICOM] PW-1 CI-V programming question

[Larry Gauthier (K8UT)]

Joe,

Is there a logging program involved here? Or is this with just the PW1 and 
radio connected on a CI-V bus?

It sounds like your 756 Pro II is set to Transceive =OFF mode. With 
transceive =OFF, rotating the dial or changing bands on the radio will not 
send data to the PW1, and your PW1 will not learn the 756 CI-V address and 
baud rate. Set the 756 for its default CI-V address, set 756 transceive =ON, 
and re-visit the steps for synchronizing the amp to the radio.

Without logging software sending frequency packets on the bus, and 
transceive =OFF, the only frequency updates between the amp and rig happened 
when the PW1 polls the radio every 10 seconds. I cannot say for sure, but 
that might also explain the strange lag in band updates between radio and 
amp.

For a thorough explanation of communication between an Icom radio and the 
PW1 amp, read Chapter Three of  "Riding the CI-V Bus" at:

Subject: [ICOM] PW-1 CI-V programming question

I'm hoping someone can help me with a PW-1 programming issue.



My 756 ProIII/PW-1 interface was working fine until some nearby lightning
strikes.  I'm trying to figure out what, if anything, has gone wrong with
the CI-V programming, or if it's just me.  Here's what happens now:



1. Pro3 is on and PW-1 is off, but the front panel frequency LED is
lit.  The Pro3 is on 20 meters and the PW-1 shows 14.
2. If I then select 15 meters on the Pro3, the PW-1 doesn't budge.
3. If I then start transmitting CW on 15 meters, the PW-1 LED switches
from 14 to 21 in about 1 second.  This will repeat no matter what frequency
I switch to.the PW-1 LED frequency won't switch until I start transmitting.



So there seems to be some communication between the Pro3 and the PW-1.  But
when I try reprogramming the CI-V address, the following takes place:



1. Pro3 and PW-1 are off.
2. Press UP and DOWN buttons and push Power on the PW-1.  This should
reset things.
3. Turn off the PW-1.
4. Press the Input button on the PW-1 and then push Power on the PW-1.
5. Press power on the Pro3.
6. Wait for the Pro3 to "boot", then rotate the Pro3 knob, which should
make the PW-1s input light go steady.  But it keeps blinking at me.  That
never used to happen in the past.



What am I missing or doing incorrectly.  I know I've done this correctly
before, so I'm confused.
