Introduction


1.1.1 ApplicationsWhen used in conjunction with EFData modems, the CST-5000 is ideal for: Single digit carriers up to 2.048 Mbit/s Multiple carrier operation over a 36 MHz bandwidth

Because the CST-5000 has a 70 MHz IF, it can also be used for other analog and digital applications. Small to medium size earth stations are easily constructed and commissioned with the CST-5000. When used with a high-gain antenna, the CST-5000 can also be used as the Radio Frequency (RF) electronics of a central hub in point-to-multipoint applications, as well as serving as the terminal for the end points of a network.

1.1.2 Monitor and Control (M&C)An on-board microcomputer monitors and controls all operational parameters and system status of the CST-5000. This powerful M&C system enables the user to control functions, locally or remotely, such as:

Output power Transmit/receive channel frequencies

The system also reports terminal configuration status, as well as fault status of all CST-5000 components. The CST-5000 can be initially configured using the: Connection of a common ASCII/EIA-232-C terminal connected to the serial port. A simple command set then allows total configuration control and retrieval of status information. Optional keyboard/LCD (Liquid Crystal Display) controller within the enclosure.

If the indoor unit is a more sophisticated station M&C computer, the serial port can be set to EIA-485 for bus operation. For more information on the M&C board, refer to Chapter 5.

Introduction

1.1.3 Low Noise Amplifier (LNA)The feed assembly consists of an LNA and a wave guide transmit reject filter. The transmit reject filter provides receive system protection from transmit energy fed back through the antenna feed system. The LNA standard noise temperature is 65K, with optional upgrades down to 33K, depending on gain over temperature (G/T) requirements.

1.1.4 Outdoor EnclosureThe RFT-500 assembly is a weatherproof enclosure housing the following:

Solid State Power Amplifier (SSPA) Up and down converters M&C microprocessor Power supply and cables, which interface with an antenna subsystem

In the transmit (uplink) direction, the RFT-500 accepts a 70 MHz IF signal, and transmits it in the 5.845 to 6.425 GHz frequency band. In the receive (downlink) direction, the terminal accepts an RF signal in the 3.620 to 4.200 GHz band, and converts the signal to a 70 MHz IF output. Power levels range from +8 dBm (for driving an external Traveling Wave Tube (TWT) or amplifier) to 40W, depending on Equivalent Isotropically Radiated Power (EIRP) requirements. The up and down converters are dual conversion, with individual synthesizers for independent transmit and receive transponder selection. The microprocessor provides: On-line loop monitoring Dynamic control functions Configuration control Fault/status monitoring Serial computer/terminal interface

1.2 OptionsContact an EFData marketing representative for more information about the options described in this section.

1.2.1 ConfigurationsThe CST-5000 can be ordered with various configurations, including: Output power levels. Input power (AC/DC). Step sizes. For example, 125 kHz step size. The 125 kHz step size option allows the transmit and receive frequencies to be adjusted within 125 kHz. The higher resolution step size of 125 kHz requires replacing the synthesizer modules and upgrading the software on the M&C board. LNA gain. Redundant LNA mounting plates. Custom logos. Wider bandwidths. The 140 MHz IF option enables the user to double the available bandwidth. Specifically, instead of the standard 70 MHz, 18 MHz, this option allows 140 MHz, 36 MHz. For more information, refer to Appendix A. Multi-carrier system. The multi-carrier option allows external separation of the up converter and SSPA for possible multiple carrier inputs. For more information, refer to Appendix A.

3. Install the 14 inch (35.6 cm) unistruts as follows: a. Position a spring nut between the inner and outer bolts on both sides of each 8 inch (20.3 cm) unistrut. b. Install each spring nut as follows: (1) Place the spring nut in the unistrut channel, spring side down, with its wide side parallel with the unistrut channel.

(2) Press down on the spring nut to compress the spring, and rotate the nut 90 (i.e., perpendicular to the unistrut).

(3) Release pressure on the spring nut. (4) Repeat Steps 3.b.(1) through 3.b.(3) for each spring nut.

210

Rev. 9



c. Position a 14 inch (35.6 cm) unistrut (open side facing up) over one of the 8 inch (20.3 cm) unistruts. Ensure the 14 (35.6 cm) unistrut is centered over the RFT.

d. Using two 5/16-18 x 1-1/4 inch (3.2 cm) bolts, 5/16 inch (8 mm) split lockwashers, and 5/16 inch (8 mm) flat washers, attach the 14 inch (35.6 cm) unistrut to the 8 inch (20.3 cm) unistrut.

Note: The bolts should be installed in the fifth hole from each end, as illustrated. Tighten the bolts firmly. e. Attach the second 14 inch (35.6 cm) unistrut to the second 8 inch (20.3 cm) unistrut by repeating Steps 3.a. through 3.d.

Rev. 9

211



4. Install the pipe blocks as follows: a. Install two spring nuts in each of four 14 inch (35.6 cm) unistruts (the two just mounted on the RFT, and two additional). Be sure to position the spring nuts in the unistruts wide enough apart so that when the pipe blocks are installed, they will clear the pole when the unit is lifted into place for installation. b. Install each spring nut as follows: (1) Place the spring nut in the unistrut channel, spring side down, with its wide side parallel with the unistrut channel. (2) Press down on the spring nut to compress the spring, and rotate the nut 90 (i.e., perpendicular to the unistrut).

(3) Release pressure on the spring nut. (4) Repeat Steps 4.b.(1) through 4.b.(3) for each spring nut. c. Using four 5/16-18 x 1 bolts, 5/16 inch (8 mm) split lockwashers, and 5/16 inch (8 mm) flat washers, loosely secure the pipe blocks to the spring nuts.

2.5.1 TX/IF Input (J1)The TX/IF input is a TNC connector that receives the signal from the indoor unit. The input impedance is 50, and the frequency is 70 MHz 18 MHz (optional 140 MHz 36 MHz). The typical power level is from -43 to -19 dBm, depending on the configuration and application.

2.5.2 TX/RF Output (J2)The TX/RF output is a type N connector that sends the signal to the antenna. The output impedance is 50. The output frequency range is from 5.845 to 6.425 GHz. The output power level is dependent on the power amplifier ordered with the system. Table 2-2 lists the maximum output power at the 1 dB compression point for each SSPA available: Table 2-2. SSPA Maximum Output PowerSSPA None 5W 10W 20W 40W System Power at 1 dB Compression Point +8 dBm +37 dBm +40 dBm +43 dBm +46 dBm

2.5.3 RX/IF Output (J3)The RX/IF output is a TNC connector that sends the received signal to the indoor unit. The output impedance is 50, and the frequency is 70 MHz 18 MHz (optional 140 MHz 36 MHz). The 1 dB output compression point is +15 dBm. Maximum output power operation is +9 dBm (-6 dB from 1 dB compression) to 50 dBm, depending on system gain requirements. The down converter has 26 to 47 dB of gain, and is adjustable by the customer from 0 to 21 dB of attenuation. The typical system gain includes a 50 dB LNA, making the total system gain 76 to 97 dB. Note: A 60 dB LNA is used only when extremely long cables are used from the LNA to the down converter.

222

Rev. 9



2.5.4 RX/RF Input (J4)The RX/RF input is a type N connector that receives the signal from the LNA. The input impedance is 50. The input frequency range is from 3.620 to 4.200 GHz. The input signal level ranges between -50 and -25 dBm, depending on LNA and antenna gain. The input level should be set to give the required signal level at J3, the RX/IF Output (refer to Section 2.5.3).

2.5.5 Prime Power (J5)The AC power is supplied to the RFT by a 3-pin circular connector. Normal input voltage is 95 to 230 VAC, 47 to 63 Hz. The AC pinout is as follows:Pin # A B C Name HI LO GND Function Line Neutral/Line Ground Wire Color Brown Blue Green/Yellow

Maximum power consumption depends on the power amplifier used in the RFT. The following is a list of maximum power consumption at each configuration:SSPA +8 dBm 5W 10W 20W 40W Maximum Power 90W 140W 210W 340W 600W

A circular 4-pin power connector is used for the 48 VDC option. The pinout is as follows:Pin # A B C D Function + INPUT CHASSIS GROUND - INPUT - N/C

Rev. 9

223



2.5.6 Serial Remote Control (J6)The remote connector on the RFT is used to interface the M&C functions to a remote location. This interface can be either EIA-232 or EIA-485. When using an EIA-485 interface, the transmit and receive signals are able to accommodate either type of remote equipment pinouts. As long as the polarities of the remote equipment TX and RX signals are correct, this remote interface will be completely compatible. Refer to Table 2-3 for a list of pinouts for the J6 connector. For standard EIA-232 or EIA-485 applications, an adapter cable must be used to connect the 26-pin connector (J6) to a standard 9-pin D. Refer to Figure 2-5 for an illustration of the adapter cable and pinouts.

Rev. 9

39



3. Install the 20 inch (51 cm) unistruts as follows: Note: The placement of the pipe blocks may interfere with the inner or center unistrut attaching bolts. Be sure to determine the pipe block placement locations before bolting the 20 inch (51 cm) unistruts in place. It may be necessary to eliminate the center or inner 20 inch (51 cm) unistrut mounting spring nuts and bolts. a. Insert a spring nut between the unistrut mounting bolts on both RFTs, as illustrated. b. To install each spring nut: (1) Place the spring nut in the unistrut channel, spring side down, with its wide side parallel with the unistrut channel. (2) Press down on the spring nut to compress the spring, and rotate the nut 90 (i.e., perpendicular to the unistrut).

(3) Release pressure on the spring nut. (4) Repeat Steps 3.b.(1) through 3.b.(3) for each spring nut.

310

Rev. 9



c. With the RFTs side-by side, position a 20 inch (51 cm) unistrut (open side facing up) in place over one pair of 8 inch (20.3 cm) unistruts. Ensure the long unistrut is centered over the RFT. d. Using two or three 5/16-18 x 1-1/4 inch (6 mm) bolts, 5/16 inch (8 mm) split lockwashers, and 5/16 inch (8 mm) flat washers, attach the 20 inch (51 cm) unistrut to the 8 inch (20.3 cm) unistruts.

Tighten the bolts firmly. e. Attach the second 20 inch (51 cm) unistrut to the second set of 8 inch (20.3 cm) unistruts by repeating Steps 3.a. through 3.d. 4. Install the pipe blocks as follows: a. Install two spring nuts in each of the two 20 inch (51 cm) long unistruts and two 14 inch (35.6 cm) long unistruts (centered in the unistruts, and wide enough apart so the pipe blocks will clear the pole when the unit is installed). b. Install each spring nut as follows: (1) Place the spring nut in the unistrut channel, spring side down, with its wide side parallel with the unistrut channel. (2) Press down on the spring nut to compress the spring, and rotate the nut 90 (i.e., perpendicular to the unistrut).

Rev. 9

311



(3) Release pressure on the spring nut. (4) Repeat Steps 4.b.(1) through 4.b.(3) for each spring nut. c. Using eight 5/16-18 x 1 inch (25 mm) bolts, 5/16 inch (8 mm) split lockwashers, and 5/16 (8 mm) flat washers, loosely secure the pipe blocks to the spring nuts.

Ensure the pipe blocks are installed with the long angle face inward, toward the pipe, as illustrated. DO NOT tighten the pipe block bolts until after mounting the RFTs on the vertical pole. (See Step 6.e.) 5. Install the threaded rods as follows: a. Install two spring nuts in both 20 inch (51 cm) unistruts mounted on the RFT. b. Install each spring nut as follows: (1) Place the spring nut in the unistrut channel, spring side down, with its wide side parallel with the unistrut channel. (2) Press down on the spring nut to compress the spring, and rotate the nut 90 (i.e., perpendicular to the unistrut).

Rev. 9



(3) Release pressure on the spring nut. (4) Repeat Steps 5.b.(1) through 5.b.(3) for each spring nut. c. Thread a 5/16-20 nut approximately 1-1/2 inch (38 mm) onto each threaded rod. (This will ensure that the threaded rods will extend beyond the spring nuts when installed.) d. Place a 5/16 inch (8 mm) split lockwasher, 5/16 inch (8 mm) flat washer, and flat fitting plate over each threaded rod. e. One threaded rod at a time, hold the washers and plate in place on the threaded rod and screw it into a spring nut, as illustrated. Notes: 1. Be sure to position the flanges of the flat fitting plates in the grooves of the unistruts. 2. Before tightening the nuts on the threaded rods, ensure that the end of each rod is screwed in until it contacts the unistrut. This ensures the rods are threaded completely through the spring nuts. Tighten each nut firmly. f. Thread a 5/16-18 nut about 2 inches (5.1 cm) onto the end of each threaded rod.

Operation

4.3.1 Front Panel ControlsThe terminal is locally operated by using the front panel keypad. The keypad consists of six keys. Each key has its own logical function or functions.Key [ENTER] [CLEAR] [] and [] [] and [] Description This key is used to select a displayed function or to execute a change to the terminals configuration. This key is used for backing out of a selection or to cancel a configuration change which has not been executed using [ENTER]. Pressing [CLEAR] generally returns the display to the previous selection. These keys are used to move to the next selection, or to move the cursor for certain functions. These keys are used primarily to change configuration data (numbers), but are also used at times to move from one section to another.

The terminal front panel control uses a tree-structured menu system (Figures 4-2 through 4-5) to access and execute all functions. The base level of this structure is the sign-on message, which is displayed at the front panel upon terminal power-up. Line 1 of the sign-on message displays the terminal model number. Line 2 displays the version number of the firmware implemented in the terminal.

The main level of the menu system is the SELECT menu, which may be accessed from the base level by pressing any of the arrow keys. From the SELECT menu, any one of three functional categories may be selected:

Configuration functions Monitor functions Fault functions

Press [] or [] to move from one selection to another. When the desired category is displayed on line 2, press [ENTER]. Once the category has been entered, move to the desired function by pressing [] or [].
