• 10 MHz reference signal
Verify that the 10 MHz reference signal is present. Some IBUC models have an
internal 10 MHz reference signal. If this option is not available, a 10 MHz
reference signal supplied on the IF cable from the modem is required.
Turning On the IBUC
To turn on the IBUC
3
or IBUC
3 G
,
1. Connect the L-band input cable (J1), the M&C cable (J4), and the power cable (J3)
2. Apply power to the IBUC.
3. The Power LED on the side of the unit next to the J4 connector lights up.
A flashing green light indicates that the IBUC is operating normally.
A red light indicates only that a fault (or alarm) has occurred. (A flashing red light
indicates a minor alarm and a solid red light indicates a major alarm.)
4. Allow the unit to warm up for approximately 15 minutes before operating the
transmitter module. This will assure stable gain and power.
Setting Operating Parameters
To set operating parameters, the IBUC must be accessed via a terminal (for example, a
terminal emulator such as HyperTerminal) or via the embedded Web pages. The most
user-friendly way to connect to the IBUC is by using the embedded Web pages. For
either methods the IBUC must be connected to the Ethernet port of a PC by using a
TCP/IP cable assembly (such as the one depicted in Figure G.2 on page G-3 ).
Note:
This Chapter of the Operations Manual describes how to connect and configure the
IBUC
3
or IBUC
3 G
via embedded Web pages. For instructions about IBUC
configuration via RS232, RS485 or Telnet, refer to Chapter F, ASCII Command/
Response Structure .
1. Establish a connection with the IBUC
3
or IBUC
3 G
by using the steps provided
in Appendix C, Embedded Web Pages .
2. Navigate to the Transmit Configuration tab as shown on page C-10 .
3. Set the Tx Output by selecting whether the unit is actively transmitting or not.
Options include:
•
Enable
•
Disable
When the Tx Output is set to Disabled, the Tx Output level displayed on the
Sensor Tab (shown on page C-9 ) reads -99.0dBm. This is not th actual reading.
