How do you change the station numbers on an old DCS? I haven't worked on one of these in about 15 years and even then there was just the one. I have a new customer that is adding rooms to their motel and I have to add an 8SLI card and change the numbers to the rooms. I downloaded the programming manual but don't see an MMC for station numbering. Also, is there anything else I have to do to install a new card?

mmc724 is where system numbering plans are. Installing a card do a mmc806 on the card first after you install it on the slot you install in.
