Figure 1-2. DT-4572 Physical Configuration

1.2.1 Applications

The DT-4572 operates over the RF frequency range with a typical gain of 45 dB. The RF output level is +20 dBm @ 1 dB compression. This permits longer cable runs and compensates for splitting networks without requiring options such as external line amplifiers.

1–2

Page 29

DT-4572 X-Band Down Converter MN/DT4572.IOM Introduction Revision 1

The phase noise performance exceeds the Intelsat phase noise mask for IBS and IDR services by more than 9 dB. This allows high capacity earth stations to add more demodulators and still meet transmission standards. The close-in phase noise is also very low. This makes the converter ideal for low bit rate digital circuits such as used in DAMA hub earth stations.

Depending on the application, the converter chassis rear panel module slot accepts an Input/Output Module (IOM), Polarity Switch Module (PSM), Transmit Switch Module (TSM), Equalizer Module (EQM), or Receive Switch Module (RSM). The converter RF, IF, and High-Speed Bus (HSB) connectors are integral to the installed module.

An IOM can be installed for switching the RF output for single thread operations, or for testing the output of the unit.

In redundancy applications, where converters are "Daisy Chained" to provide distributed online protection switching to a backup converter (BU), a TSM is used in place of an IOM. The TSM contains RF and IF transfer switches. Type ‘N’ female connectors are provided for the RF loop, and 50 Ω or 75Ω BNC female connectors are provided for the IF loop.

The "Daisy Chain" configuration is designed to chain the IF output of up to twelve (12) online converters through RSMs terminating in a BU. When a fault occurs in an online converter, the RSM in the faulted converter is commanded to switch to the BU.

The BU in the "Daisy Chain" communicates with the online converters through the installed module’s High Speed Bus (HSB data interface). When faults are detected, the BU reconfigures itself to replace the faulted online converter. The BU also uses the HSB to monitor configuration changes made to the online converters by either remote control or front panel command inputs.

The BU performs fault detection, self-reconfiguration, and logical switching functions. If the BU has a fault, it is prevented from performing the protectionswitching task. If the BU does not have a fault, it assumes the frequency and attenuation of the faulted online converter, and compensates for the chain losses.

1–3

Page 30

DT-4572 X-Band Down Converter MN/DT4572.IOM Introduction Revision 1

Changes in frequency, attenuation or polarity are entered into the backup table as they are made, as well as information from new online units. The HSB does not interfere with the remote control communications link for access to any of the converters in the "Daisy Chain".

1.2.2 RF Signal Conversion

Figure 1-3. Functional Block Diagram

Figure 1-3 depicts the functional block diagram for the DT-4572 in single thread (standalone) applications. See Appendix A. REDUNDANT SYSTEM OPERATION for more information about the converter’s use in redundant applications.

As a typical example of the RF signal processing, the RF input to the DT-4572 is 7250 to 7750 MHz at a typical level of -45 dBm. The RF is mixed in the first mixer with a 6030 to 6530 MHz synthesizer signal from a multiplier, in 125 kHz fine tuning steps.The synthesizer is locked to a 5/10 MHz reference oscillator. (The first mixer is located in the converter Signal Path Module, and the synthesizer consists of a Coarse/Fine Step Module and a Sum Loop Module.)

1–4

Page 31

DT-4572 X-Band Down Converter MN/DT4572.IOM Introduction Revision 1

The intermediate IF of 1230 MHz is mixed in the second mixer with the 1290 MHz IFLO providing a +20 dBm @ 1 dB compression, 70 MHz IF output. (The second mixer is also located in the converter Signal Path Assembly.)

1.2.3 Monitor & Control

The Monitor & Control Assembly is designed to monitor the functions of the DT-4572, and provide the local and remote control command inputs to the converter.

For Local Monitor & Control: Local operator input commands and the status of the DT-4500 display on the front panelVACuum Fluorescent Display (VFD). The unit indicates converter faults via the front panel “FAULT” and “STORED FAULT” LED indicators. Use the VFD and local keypad to browse and manage the stored events and faults log.

For Remote Monitor & Control: All configuration control, status retrieval and adjustments are available with connections to the converter rear panel:

• A DB-9F selectable EIA-232C/EIA-485 ‘J1 | COM1’ female connector

interface provides serial-based remote control communications. ASCII commands and queries are issued through the serial remote interface.

• A female RJ-45 100BaseTX ‘Ethernet’ connector interface provides

Ethernet-based remote monitor and control capability via the S N M P, Telnet, or HTTP (Web Server) Interfaces.

4.1.1 Coaxial Cable Connections

(TOP) Bayonet Coupling Plug and Jack (Type ‘BNC’ Shown)

(BOTTOM) Threaded Coupling Plug and Jack (Type ‘N’ Shown)

Figure 4-1. Coaxial Connector Examples

The types of coaxial cables used by Comtech EF Data are ‘BNC’, ‘TNC’, ‘N’, ‘F’, and ‘SMA’. Coaxial cables (plugs) and their mating connectors (jacks/sockets) are available in two coupling styles – Bayonet or Threaded:

Bayonet Coupling Style – The jack has a pair of guideposts that accommodate the plug’s lockdown slots. This lockdown design provides secure assembly without over-tightening the connection.

Threaded Coupling Style – The jack features external threads. The plug shell features internal threads, and has either a knurled outer surface to permit handtightening of the connection, or hex flats to accommodate torqued installation.

Connection Instructions

Bayonet Coupling Connections – Use the plug slots to guide, and then slide the plug onto the jack posts. Then, turn the plug clockwise until the jack posts are fully seated within the plug slot.

Threaded Coupling Connections – Engage the plug onto the jack threads, and then turn the plug clockwise until it is fully threaded onto the jack. Do not overtighten the connection.

The DT-4572 firmware download hyperlink for the Ethernet-ready current production unit (i.e., Ver6x chassis) is F0000202x_V###.

The DT-4572 firmware download hyperlinks for older, non-Ethernet units (Ver5x and earlier chassis) are as follows:

• Ver5x Units / 1 kHz Step Size: F1611-1x_v###

• Ver5x Units / 125 kHz Step Size Units: F1610-1x_v###

• Ver4x Units / 1 kHz Step Size Units: F1604-1x_v###

• Ver4x Units / 125 kHz Step Size Units: F1603-1x_v###

Note that ‘x’ is the firmware revision letter, and ‘###’ represents the firmware version number (e.g., V123 = Version 1.2.3).

Comtech EF Data provides its archive download files in two compressed formats – *.exe (self-extracting) and *.zip (compressed):

• The self-extracting *.exe file does not require use of a third-

party utility program.

• Some firewalls do not allow the download of self-extracting

*.exe files. You must instead download the *.zip file, and extract the firmware files from the download with a user-supplied third-party file archiver and compression utility program such as PKZIP for Windows, WinZip, ZipCentral, etc. (PKZIP for DOS is not supported due to file naming conventions). Comtech EF Data does not provide this utility program.

production unit differ as follows:

(LEFT) Liquid Crystal Display (LCD) – Initially Released Chassis

(RIGHT) Vacuum Fluorescent Display (VFD) – Current Production Unit

DT-4572

SW VER X.X.X SN#########

See Figure 6-1, Item 2.The VFD is an active display showing two lines of 24 characters each. It produces a blue light with adjustable brightness. On most menu screens, you will see a flashing, solid-block cursor that blinks at a onceper-second rate. This indicates the currently selected item, digit, or field:

CONFIG MONITOR FAULTS

PRE-SELECTS UTILITY

Where this solid block cursor obscures the item under edit (e.g., a numeric field), the cursor automatically changes to an underline cursor:

IP Address/Range:

192.168.001.006/24

To prevent the display from becoming burnt by a constant image, the unit employs a screen saver feature that activates after one hour. This message constantly scrolls and wraps across the screen. The top line displays the AID (the user-defined name for the unit); the bottom line displays the message “Press any key…” as shown:

Circuit ID:-------------

---Press any key...

Press any key to restore the previously active screen.

The keypads for the initially-released chassis and the current

Front Panel Operation Revision 1

6.1.4 Keypad

production unit differ as follows:

(LEFT) “Square” Button Keypad – Initially Released Chassis

(RIGHT) “Round” Button Keypad – Current Production Unit

See Figure 6-1, Item 3.The keys for the current production unit keypad have a positive ‘click’ action that provides tactile feedback.

Enter data via the keypad. Data, prompts, and messages are displayed on the VFD. Operation of the individual keys is as follows:

• Use the ENTER key to select a displayed function or to execute a unit

configuration change.

• Use the CLEAR key to back out of a selection or to cancel a configuration

change that has not been executed using ENTER. Pressing CLEAR generally returns the display to the previous selection.

• Use the  (LEFT) and  (RIGHT) keys to move to the next selection or to

move the cursor functions. At times, they may also used to move from one section to another.

• Use the  (UP) and  (DOWN) keys to change configuration data

(numbers). You may also use these keys to move from one section to another.

The keypad has an auto-repeat feature. If a key is held down for more than 1 second, the key action will repeat, automatically, at the rate of 15 keystrokes per second. This is particularly useful when editing numeric fields, with many digits, such as the IP Address assignments.
