6400 to MercuryIII Amplifier

Looking for guidance on connecting my 6400 to a new MercuryIII amp. Read the Flex document on amplifier connections, which helped, but was lacking specifics.
Is it straight cables for Key and ALC, or do I need an isolator or other interface? For those running this combo, I would like to hear from you; have you found any operational changes with the Flex?

Thanks in advance for the information.

    Yes, straight cables for Key and ALC. But, I don't use ALC. Set TX Delay to at least 10ms and I set Delay for 10ms minimum also.

    Thanks, John. Any other setting adjustment for CW or PSK?

    That's all I do for CW. I leave it for SSB but just use PTT. I don't do other modes. 73
