6. Edit the slave copy of rio.cf (see Appendix B rio.cf administration file for syntax) as
follows;
a. Replace master host card details with slave host card details.
b. Alter the slave host card "boot" setting to "noboot". (e.g. "HOST:a5000387:HOST
1:noboot:")
7. On the slave system, run the rioconfig utility to create port devices.
8. Connect the RTAs to the slave system. See Installing Remote Terminal Adaptors

accessible from the
master system.
