7 seg clock display 1.2" ID 1266

by sporex on Thu Dec 27, 2018 1:19 pm

Hi everyone,
I need a 1.2" clock display like the Prod ID 1266.
Problem is that is has I2C interface wich is limited in terms of cable length I suppose.
The clock displays I need, have to be connected to a controller with a cable of up to 400m, ideally they can be chained.
I was thinking about a RS422 serial bus to bridge the distance from the controller to the display and then employ a conversion IC from serial TTL to I2C.
Is such a thing possible? Can anyone point me to a suitable IC?

Kind regards
Chris
