IBUC Operation Manual

This is the default setting of the IBUC. In this mode the BUCMON program supplied on
the CD accompanying the unit is the simplest method to communicate with the IBUC.
Otherwise, a network management program must be provided.
HANDHELD TERMINAL (HHT):
No IBUC configuration is required to use the HHT. To activate the HHT, connect the
supplied cable to the IBUC connector labeled J2 and plug the phone jack into the HHT.
Once a flashing cursor is seen in the upper left part of the screen, press the decimal key
on the HHT 4 times to activate the HHT. The login screen will appear. Enter the default
password of 1234.
The Handheld Terminal Menu Tree is in the Operation Manual, Chapter 6, Figure 6.2.
FSK LINK:
Several brands of Modem have the capability to communicate with a Block Up
Converter (BUC) using an FSK signal multiplexed onto the IF output connector along
with the Tx IF signal and 10 MHz reference. This enables the operator to monitor and
control the IBUC from the modem front panel. The IBUC default configuration is
RS485/FSK Mode 1 (Legacy Binary mode) since all modems currently require this
protocol for FSK links. The IBUC is also capable of FSK communication using ASCII
mode but requires a modem compatible with this method. Refer to the modem manual
for commands and procedures for FSK communication with the IBUC.
A Multi-function LED is mounted on the IBUC housing to provide visual indications of
IBUC status. LED colors and modes are as follows:
Flashing Green - No Alarms
Flashing Red - Minor Alarm being reported
Steady Red - Major Alarm being reported
Major and Minor alarms are defined in the Chapter 6 of this manual. Note that certain
alarms are configurable giving the user the ability to define them as Major or Minor
alarms.
