If the user chooses to disable the multifunction LED, several methods are at disposal.
One might disable multifunction LED via: System Configurations Tab of the Web
pages, described on
; via the ASCII command “
”, described on
; or via the Hand-held terminal described on
.
Frequency Shift Keying (FSK) Modem Interface
Several modem brands have the capability to communicate with an IBUC using an
FSK signal multiplexed onto the IF output connector with the Tx IF signal and the
10MHz reference signal. The default configuration for the IBUC is RS485/FSK Mode
1, which enables compatible modems to use “Legacy Binary” mode to communicate
with the IBUC. The IBUC is also capable of FSK communication using ASCII mode,
but requires a modem compatible with this method. Refer to the modem’s
documentation for more information about commands and procedures for FSK
communication with the IBUC.
FSK and RS485 are tied together by the mode of operation (Legacy Binary or ASCII).
Once the mode is selected, both FSK and RS485 will work in the same mode. FSK and
RS485 also share a common address. The message formats for both FSK and RS485
are the same. Transmitter link specifications are detailed in
