adapter to the controller for either C-Bus systems or stand-alone controller applications. No additional hardware is necessary. Excel 50/100/500/800 controllers can store 100 trend values (by default) for the connected EBI/SymmetrE, in addition to handling normal building control functions. Data transmission rates up to 38.4 Kbaud are supported with modem/ISDN terminal adapter attached.

If no special modem behavior is needed, it is not necessary to set up or initialize the modem/ISDN terminal adapter. The Excel 50/100/500/800 controller will detect the modem attached to the serial port and set the communication speed to the default value of 9.6 Kbaud. The Excel 50/100/500/800 controller will also detect whether the modem/ISDN terminal adapter is initialized in auto-answer or manu-answer mode, and it will initialize the modem for manu-answer mode (S0=0).

NOTE: Remote communication to XBSi building supervisors is not supported by direct modem connection.

NOTE: IRC alarming can be accomplished only indirectly with firmware version V2.01.xx by using a separate Excel 500 controller with special operating system firmware (XL IRC V1.03.x) which allows mapping between it and an IRC Multicontroller. In that case, the IRC alarms are treated like normal C-Bus data.
