- Disconnect the TX L-band input signal.
- Remove the waveguide to coax transition and install the transmit waveguide section
to the antenna transit feed.
- Once the transmit input and output power levels have been set, begin transmitting
by connecting the TX L-band input signal to J1 on the IBUC and enabling the TX in
the modem or converter.
- Under the guidance of the Network Operations Center (NOC), fine adjust the
transmit power for the desired down link margin at the receiving station by adjusting
the TX L-band output level adjust (modem or converter output).
Final Checks
To ensure optimum operation, inspect the system for crimped or pinched cabling. Make
sure all connections are secure and sealed. Once the system has been aligned and is
operating satisfactorily, the IBUC will require a few infrequent and simple maintenance
procedures as described in Maintenance and Service, chapter 5.
M&C Setup
Note: RS485/FSK Mode 1 is the default setting to enable compatible modems to use
the "Legacy binary" mode to communicate with the IBUC.
General
Communication with the IBUC can be accomplished via any of five interfaces: TCP/IP,
RS232, RS485, Handheld Terminal (HHT), and FSK Link. The first four use the M&C
connection (J2) with an appropriately configured cable and terminal. FSK Link uses
FSK signals between the IBUC and modem that are multiplexed on the IFL coax cable.
TCP/IP:
Communication with the IBUC via TCP/IP can be through Telnet (ASCII) or the onboard
web server (HTTP). The IBUC uses a static IP addressing structure and does not
support DHCP. The IBUC is factory-configured as follows:
IP Address 192.168.1.21
IP Gateway 192.168.1.1
Subnet Mask 255.255.255.0
Telnet Port 23
Note: Your computer should have a static IP address on the same subnet as the IBUC.
Using a suitable cable, connect the computer to the IBUC J2 connector. Note: If an
Ethernet hub is not used to connect to the IBUC, then a crossover cable must be used.
An Ethernet hub will function with a straight connect cable.
