EXCEL 50/100/500/600/800 COMMUNICATION

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.
