Its possible physically to use the 7I90 SPI this way but there's no driver support, so it would require a custom component, SPI is not great for noise immunity/long cables either. Much easier and better electrically is to use the 7I90HD in sserial (RS-422) remote mode using the 7I90HD's built in RS-422 port.
