Palapa C-band, Insat C-band, Extended C-band, Standard Ku-band, Extended Ku- band and Full Ku-band. The C-band IBUC is available in 5, 10, 20, 25, 40, 60, and 80 watt configurations. The Ku-band IBUC is available in 4, 8, 12, 16, 20, 25, 30 and 40 watt configurations.
Page 21 The IBUC is equipped with extensive monitor and control (M&C) capabilities. There are five ways to remotely access the M&C capabilities of the IBUC. First is via the M&C 19- pin circular connector (J2) utilizing two wire RS485. In order to access the RS485, a separate cable must be run and connected to J2.
Page 22: Figure 3-1 Ibuc Block Diagram
The mixer mixes the L-band signal with the DRO signal to “upconvert” to the appropriate RF signal based on the frequency band of the IBUC. The RF signal is then filtered, amplified and routed to the temperature compensation circuitry. The temperature compensation circuitry has been calibrated over temperature so that the IBUC gain does not vary more than 3dB at any frequency.
Page 23: Low Noise Blockconverter (Lnb)
LNB will amplify the RF input signal and downconvert it to an L-band signal. Like the IBUC the DRO is phase locked to the 10MHz signal that has been multiplexed on to the L-band output connector. The 10MHz input level must be between 0 and –10 dBm and must meet the minimum phase noise requirements (see chapter 9).

On/Off switch. This unit can have up to two Power Supplies internally, a 200W 24V or 48V for the IBUC and a 28W 24V for the 10MHz OCXO and LNB. The outputs of both AC/DC converters are routed to the Interface card, where they’ll be multiplexed to the L-Band to feed the IBUC and the LNB, and in case of the 28W supply, converted to 12VDC to feed the OCXO.
Page 25 10MHz reference. The internal 200W Power Supply can power up to 12W IBUC’s. If configured with the 200W DC Supply, the chassis will be equipped with a fan. The front panel is also provided with a green LED that allows the user to verify if the unit is powered up.
Page 26: Software
Automatic Gain Control (AGC) – the IBUC continuously monitors output level. When AGC is enabled, if a change in the TX output level is detected, the input to the IBUC is checked to see if it has changed. If the input has not changed the IBUC adjusts the gain of the system in 0.1 dB steps to maintain a set gain value.

Setup ______________________________________________________________________ The Terrasat ODU consists of an IBUC, and could include an LNB, a PSUI and a set of interconnection cables. The Terrasat IDU consists of an IFU. This section contains the general requirements for installation of the ODU to the antenna and the IDU between the Modem and the ODU.
Page 28 Size 3/0 or 4/0 AWG stranded copper wire should be used to ground the IBUC, the PSUI and the LNB to the antenna frame and to the lightning protection ground rod. For the higher power units with an external power supply provide an isolation filter to reduce power line interference as required.
Page 29 For IBUC’s with a rated power level of 12 watts and below the power for the IBUC may be through the L-band IFL supplied from the satellite modem or from the Terrasat indoor IFU. The IBUC DC power can also be supplied directly through the external power connector (J3).
Page 30: Installing The Indoor Ifu
PSUI to the antenna. Terrasat offers an optional mounting bracket to simplify antenna mounting. Refer to chapter 9 for mounting hole dimensions. The LNB is mounted directly to the OMT at the focal point of the antenna. Ensure that proper gasketing is used when mounting the LNB to the OMT.

LAN connection. Connect the DC cable between the outdoor PSUI J2 (DC Output), as appropriate, and the IBUC J3 (DC Input). Low power units can be supplied from the Modem or the IFU through the coaxial cable to the IBUC.
Page 39 It is recommended that 3/0 or 4/0 AWG (American Wire Gauge) stranded copper wire be used to bond the IBUC and the PSU to the earth ground (grounding rod), using the most direct (shortest) route.
Page 40: System Alignment And Operation
(calibrated up to 15 GHz) Ensure that the IBUC TX output power is disabled to prevent accidental transmission interference with adjacent satellites or transponders before attempting to align or performing any other operation involving the ODU. Before attempting any system change, carefully evaluate the possible effects of the transmitted signal.
Page 41 Use the modem or converter level adjust to increase and decrease the power level. Adjust this for a level of -30 dBm (this will result in rated power at the IBUC output). For shorter cable runs the attenuator in the IBUC may be used.
Page 42: Final Checks
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).
Page 43 Change the IP address to something other than 192.168.1.21 (the factory default) Press “Update”. Note that IP address changes will not take effect in the IBUC until it is reset. Using the Webpage to change address will reset the unit automatically. In the host computer web browser type the new address and come back in through the Login page.
Page 44 The default configuration is Legacy Binary mode so it will be necessary to reconfigure the IBUC in order to use ASCII mode. ASCII mode can be selected via the web page in TCP/IP or using the HHT or RS232 to configure the 485 address (1), 485 line delay (20), 485 mode (0) and 485 baud rate (9600).
Page 45 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 J1 for the A IBUC or J8 for the B IBUC 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.
Page 114 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.

Power supply units are mounted on a similar plate that is meant to be mounted close to the IBUC system. See Chapter 9 for outline drawings of the redundancy mounting system.
Page 118 The information contained in this section should suffice in determining whether a Terrasat Redundant System is faulty. The intent is to determine a "GO" or "NO GO" situation based on alarms indicated through the M&C ports, as well as measuring certain signals using test equipment.
Page 119 If M&C is not available, use a multimeter to verify that the appropriate voltages (24VDC or 48 VDC) are present at the IBUC and Rx 1+1 Interface Module. The labeling on the IBUC’s has the required voltage (24VDC or 48VDC).
Page 120 If the L-band and 10MHz signals are good check that the DC voltage level is within range. The DC voltage will be on the DC cable that is connected to the IBUC’s J3 (DC Input). If it is not, check the PSUI’s outputs and cables.
