?

A direct connection between transceiver and amplifier is not supported by DXLab Suite.? If you are using that connection, please seek help from Icom or one of the Icom support lists.

+ The PW1 fails to comply with Icom's CI-V bus specification. Like the Ethernet, the collisions can occur on the CI-V bus. However, the PW1 does not properly detect and recover from collisions.

+ With an Icom transceiver connect to a PW1 via a CI-V bus, no collisions occur.

+ With an Icom transceiver connected to a PW1 and a PC Com port managed by a transceiver control application like Commander, collisions can occur. Because it does not properly handle collisions, the PW1 can transmit on the wrong frequency, which can result in serious damage to the PW1. This is described in detail in this document developed by Larry K8UT:

+ Commander's Secondary Com port enables provides a dedicated CI-V bus for the PW1 on which no collisions can occur, thus preventing damage to the amplifier. It has been successfully employed by many PW1 users.
