Can my Remote I/O option board be swapped to a different Hardy Instrument?

The same Remote I/O (RIO) option board is used in the HI 2151/30WC, HI 2110WI, HI 2160RC and the older HI 2151/20WC. Before removing the RIO option board, enter the option menu and write down the baud rate, rack number and quarter number, if applicable. After the RIO option board is installed in a different unit, enter the option menu and then enter the baud rate, rack number and quarter number, if applicable.
