We're having problems using the 8 bit AMI control protocol with the IO64. The IO64 never answers.
Here is an example 'Start Sequence #2' frame you can send to the I/O 64 into its REMOTE port. Just as a very simple test, have sequence #2 turn on output 2 or something like that.
0xF5 0x00 0x01 0x02 0x18 0x01 0x1C This looks for an ACK/NAK
0xF5 0x00 0x02 0x02 0x18 0x01 0x1D This looks for the whole string and ACK/NAK
Also don't forget to configure the REMOTE port as Alcorn_8_Bit_Control.
This approach can be applied to any of our show control units using any one of the 8bit ports.
