Yes , that's fine, but you need to know the TTL async protocol to before it
can be converted to I2C protocol. I asume it's a UART type message or
something, but one does need to know!

I thought RS422 was an electrical protocol & I2C a data format protocol?

It is, hence the need for a two staged process. 1: to convert RS422 to
TTL and the other way round. and 2: to convert the TTL Async to I2C,
in a manner you can access either any I2C device, or a particular one
over the serial link.
