4.5 Monitoring Operations via the LED Indicators

The MBT-4000 Multi-Band Transceiver System features two Light-Emitting Diode (LED) indicators – one for each operational unit (module). Each LED provides the user with visual cues to the operational, online, and offline status of the sytem.

Figure 4-1 illustrates the location of the LED Indicators. Located on the top of the MBT-4000’s

Base Module under a pivoting protective plate, the LEDs may be viewed by loosening the thumbscrew that keeps the plate in place; the user can then swing the plate away to reveal the

LED display window.

Appendix B. FAULTS/EVENTS provides complete details for interpreting the LED Indicators.

2.2 Installation

The Base Module for the MBT-4000 system – which provides the M&C,

Power Supply, and Reference interfaces – may be located near or on the antenna. Guide pins and mechanical clamps keep the bandspecific BUC and BDC modules in place on top of the Base Module.

Cables to the antenna and IDU complete the installation. For complete information on the

MBT-4000’s connectors, including the pinout tables, refer to Chapter 3. EXTERNAL

CONNECTORS.

To change the band of operation, the cables to the BUC/BDC modules are disconnected and the modules are unlatched from the Base unit, allowing removal and replacement of the existing modules with appropriate band-specific modules.

2.3 Operation

Once all pertinent connections have been made between the MBT-4000 and other equipment, refer to Chapter 4. SYSTEM OPERATING PARAMETERS for further information.

4.5 Monitoring Operations via the LED Indicators

The MBT-4000 Multi-Band Transceiver System features two Light-Emitting Diode (LED) indicators – one for each operational unit (module). Each LED provides the user with visual cues to the operational, online, and offline status of the sytem.

Figure 4-1 illustrates the location of the LED Indicators. Located on the top of the MBT-4000’s

Base Module under a pivoting protective plate, the LEDs may be viewed by loosening the thumbscrew that keeps the plate in place; the user can then swing the plate away to reveal the

LED display window.

Appendix B. FAULTS/EVENTS provides complete details for interpreting the LED Indicators.

Chapter 5. FLASH UPGRADING

5.1 Overview

This chapter provides procedural information for upgrading the firmware for the Base Module of the Comtech EF Data MBT-4000 Multi-Band Transceiver System. This is a technical document intended for users – i.e., earth station engineers, technicians, and operators – responsible for the operation and maintenance of the MBT-4000. This chapter also assumes that the user has familiarity with Microsoft Windows-based operating systems.

5.2 Flash Upgrading via Internet

The MBT-4000 uses internal ‘Flash memory’ technology; this makes firmware upgrading very

simple, and updates can now be sent via the Internet (Figure 5-1), via E-mail, or on CD.

This chapter outlines the complete upgrading process as follows:

• New firmware update for upgrading the MBT-4000 Base Unit is transferred to a userprovided PC intended for Monitor and Control (M&C) of the MBT-4000 system.

• By simply connecting the MBT-4000 to an available serial port on the user-provided PC, the upgrade can then be performed without opening the MBT-4000 base unit. (Note: The block up and down converter modules are factory-serviced items, and are not updated during this procedure.)

• Once the firmware update is extracted from the transferred archive file, the upgrade process is executed via use of a utility program, FLSHCSAT.exe.

Flash Upgrading

Revision 4

MN/MBT4000.IOM

5.2.1 Firmware File Transfer Procedure

1. Identify the reflashable product, firmware number, and version for download.

Using serial remote control, the current MBT-4000 firmware revision can be determined with the following query: <0/ FRW?

2. Create a temporary directory (folder) on the user-provided external PC.

Windows: Select File > New > Folder, then rename the New Folder to "temp" or another convenient, unused name. Assuming "temp" works, a "c:\temp" folder should now be created.

Note: The c: is the drive letter used in this example. Any valid writable drive letter can be used.

CMD Prompt: At the command prompt (c:\>), type "mkdir temp” or “MD temp" without quotes (mkdir and MD stand for make directory). This is the same as creating a new folder from Windows. There should now be a "c:\temp" subdirectory created (where c: is the drive letter used in the example).

3. Download the correct firmware file to this temporary folder as shown in Figure 5-1:

1. Go online to: www.comtechefdata.com

2. Click on: Support tab

3. Click on: Software Downloads drop-down or hyperlink from Support page

4. Click on: Download Flash and Software Update Files icon

5. Click on: (Select a Product Line) Transceivers hyperlink

6. Select the appropriate firmware hyperlink from the roster of displayed MBT-4000 products/components.

The flashable files on the download server are organized by product prefix. Depending on the product for which it is intended, the file name may designate the firmware number (verify that the correct firmware number is known – see Step 1); revision letter, if applicable; version; and release date. The naming convention for MBT-4000 Base Unit firmware is FW11811*.CCC

(where the asterisk signifies the firmware revision letter).

The current version firmware release is provided. If applicable, one version prior to the current release is also available. Be sure to identify and download the desired version.

The downloadable files are stored in two formats: *.exe (self-extracting) and *.zip

(compressed). Some firewalls will not allow the downloading of *.exe files. In this case, download the *.zip file instead.

For additional help with "zipped" file types, refer to PKZIP for Windows, WinZip, or

ZipCentral help files. PKZIP for DOS is not supported due to file naming conventions.

4. Extract the files to the temporary folder on the PC, then verify the success of the file extraction and transfer via the dir command. At least four files should be extracted:

• ReleaseNotes_vX-X-X.pdf, where “X-X-X” denotes the firmware version.

• FW11811x.CCC, where "x" denotes the firmware revision letter.

• FLSHCSAT.EXE: CEFD Flash Upload Utility

Program.

• CCCflash.hlp: FLSHCSAT Help File.

If these four files as identified are displayed, proceed to the next section to perform the flash upgrade.

Revision 4

MN/MBT4000.IOM

Appendix A. REMOTE CONTROL

A.1 Overview

This appendix describes the protocol and message command set for remote monitor and control of the MBT-4000 Multi-Band Transceiver System (more specifically, the BUC-4000 and

BDC-4000 modules).

The electrical interface is either an RS-485 multi-drop bus (for the control of many devices) or an

RS-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form using ASCII characters. Control and status information is transmitted in packets of variable length, in accordance with the structure and protocol defined in later sections.

A.2 RS-485

For applications where multiple devices are to be monitored and controlled, a full-duplex (or 4wire plus ground) RS-485 is preferred. Half-duplex (2-wire plus ground) RS-485 is possible, but is not preferred. In full-duplex RS-485 communications, there are two separate, isolated, independent, differential-mode twisted pairs, each handling serial data in different directions.

It is assumed that a 'Controller' device (a PC or dumb terminal) transmits data in a broadcast mode via one of the pairs. Many 'Target' devices are connected to this pair, and all simultaneously receive data from the Controller. The Controller is the only device with a line-driver connected to this pair – the Target devices have only line-receivers connected.

In the other direction, on the other pair each Target has a tri-stateable line driver connected, and the Controller has a line-receiver connected. All the line drivers are held in high-impedance mode until one (and only one) Target transmits back to the Controller. Each Target has a unique address, and each time the Controller transmits, the address of the intended recipient Target is included in a framed 'packet' of data. All of the Targets receive the packet, but only one (the intended) will reply. The Target enables its output line driver and transmits its return data packet back to the Controller in the other direction, on the physically separate pair.

RS-485 (full duplex) summary:

•

Two differential pairs – one pair for Controller-to-Target, one pair for Target-to-Controller.

•

Controller-to-Target pair has one line driver (Controller), and all Targets have line-receivers.

• Target-to-Controller pair has one line receiver (Controller), and all Targets have tri-state drivers.

A–1


Remote Control

Revision 4

MN/MBT4000.IOM

A.3 RS-232

This is a much simpler configuration in which the Controller device is connected directly to the

Target via a two-wire-plus-ground connection. Controller-to-Target data is carried, via RS-232 electrical levels, on one conductor, and Target-to-Controller data is carried in the other direction on the other conductor.

A.4 Basic Protocol

Whether in RS-232 or RS-485 mode, all data is transmitted as asynchronous serial characters, suitable for transmission and reception by a UART. The asynchronous character is fixed at 8-N-1

(8 data bits, no parity, one stop bit). Only two baud rates are supported: 9600 baud and 19200 baud.

All data is transmitted in framed packets. The Controller is assumed a PC or ASCII dumb terminal that is in charge of the process of monitor and control. The Controller is the only device that is permitted to initiate, at will, the transmission of data. Targets are only permitted to transmit when they have been specifically instructed to do so by the Controller.

All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return and Line Feed characters are considered printable.

All messages from Controller-to-Target require a response – with one exception: This will be either to return data that has been requested by the Controller, or to acknowledge reception of an instruction to change the configuration of the Target. The exception to this is when the Controller broadcasts a message (such as Set Time/Date) using Address 0, when the Target is set to RS-485 mode.

Target-to-Controller: This is the character '>' (ASCII code 62)

Because this is used to provide a reliable indication of the start of packet, these two characters may not appear anywhere else within the body of the message.

A.5.2 Target Address

Up to 9,999 devices can be uniquely addressed. In both RS-232 and RS-485 applications, the permissible range of values is 1 to 9999. It is programmed into a target unit using the remote control port.

The BDC and BUC subdevices may also be addressed by appending the corresponding subdevice address. The subdevice address is ‘A1’ for the BUC and ‘A2’ for the BDC. For example, a mute command addressed to a BUC attached to an MBT-4000 at address 0412 will be:

<0412A1/MUT=1{CR}

The format of the response will be:

>0412A1/MUT={CR}{LF}

Subdevice addresses cannot be changed.

IMPORTANT

The Controller sends a packet with the address of a Target - the destination of the packet. When the Target responds, the address used is the same address, to indicate to the Controller the source of the packet. The Controller does not have its own address.

A.5.3 Address Delimiter

This is the ‘forward slash’ character '/' (ASCII code 47).

A.5.4 Instruction Code

This is a three-character alphabetic sequence that identifies the subject of the message. Wherever possible, the instruction codes have been chosen to have some significance. This aids in the readability of the message if seen in its raw ASCII form. Upper and lower case alphabetic characters (i.e., A-Z – ASCII codes 65-90, and a-z – ASCII codes 97-122) may be used.

A.5.5 Instruction Code Qualifier

This single character further qualifies the preceding instruction code. Code Qualifiers obey the following rules:

1. From Controller-to-Target, the only permitted values are:

=

(ASCII code 61)

?

(ASCII code 63)

The = code is used as the assignment operator, and is used to indicate that the parameter defined by the preceding byte should be set to the value of the argument(s) that follow it. For example: MUT=1 would mean 'enable the Mute function.'

The ? (ASCII code 63) is used as the query operator, and is used to indicate that the Target should return the current value of the parameter defined by the preceding byte. For example: MUT? Would mean ‘return the current state of the

Mute function.’

2. From Target-to-Controller, the only permitted values are:

=

(ASCII code 61)

?

(ASCII code 63)

!

(ASCII code 33)

*

(ASCII code 42)

#

(ASCII code 35)

The = code is used in two ways:

First, if the Controller has sent a query code to a Target (for example: MUT? would mean ‘return the current state of the Mute function’), the Target would then respond with MUT=x, where ‘x’ represents the state in question (1 being

‘enabled’, 2 being ‘disabled).

Second, if the Controller sends an instruction to set a parameter to a particular value, then, providing the value sent in the argument is valid, the Target will acknowledge the message by replying with MUT= (with no message arguments).

The ? code is only used as follows:

If the Controller sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is not valid, the Target will acknowledge the message by replying (for example) with MUT? (with no message arguments). This indicates that there was an error in the argument of the message sent by the Controller.

The ! code is only used as follows:

If the Controller sends an instruction code that the Target does not recognize, the Target will acknowledge the message by echoing the invalid instruction, followed by the ! character; for example, XYZ!

The * code is only used as follows:

If the Controller sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is valid, but the target is in the wrong mode (e.g., Standby mode in Redundancy configuration) such that it will not permit that particular parameter to be changed at that time, the Target will acknowledge the message by replying (for example) with MUT* (with no message arguments).

The # code is only used as follows:

If the controller sends an instruction code that the target cannot currently perform because of hardware resource issues, then the target will acknowledge the message by echoing the invalid instruction, followed by the # character; for example, MUT# (with no message arguments).

A.5.6 Optional Message Arguments

Arguments are not required for all messages. Arguments are ASCII codes for the characters 0 to 9 (ASCII codes 48-57), period (ASCII code 46), and comma (ASCII code 44).

A.5.7 End of Packet

Controller-to-Target: This is the 'Carriage Return' character (ASCII code 13).

Target-to-Controller: This is the two-character sequence 'Carriage Return', 'Line Feed' (ASCII codes 13 and 10).

Both indicate the valid termination of a packet.

MBT-4000, BDC-4000, or BUC-4000:

• Summary Faults

• Configurable Summary Faults

• Informational Events.

Each of these are described in further detail in the next subsections; Tables B1 through B6 list possible Fault/Event messages where applicable.

An example of a faulted system is shown in

Figure B-2; here, Unit 2 has faulted.

Figure B-2. Faulted System Example

B.2.1 Summary Faults

Summary Faults indicate improper operation. When a Summary Fault condition occurs, the

Summary Fault Relay will be de-energized. If a Summary Fault occurs on a converter, it will mute. If a Summary Fault occurs on the base unit, the applicable converters (one or both) will be muted according to the specific error. If a Summary Fault occurs on the online unit of a redundant pair, the offline unit will detect the fault and assume online state. In all cases, a corresponding event message will be added to the event log.

Appendix C. REDUNDANCY

CONFIGURATION / OPERATION

C.1 Overview

The MBT-4000 is designed to operate in both stand-alone and redundant configurations. Every

MBT-4000 base contains the circuitry and logic necessary to perform all the functions of a backup controller in either a single base and dual base configuration. The BDC-4000 is capable of supplying LNA power over the center conductor of the coaxial cable. This power supply features current monitoring with programmable failure limits. Overcurrent and undercurrent failures can participate in overall fault indication and redundant switchover criteria.

Each MBT-4000 base includes two “AUX COMM” connectors. Each of these connectors includes a logic input intended to be connected to contact closure fault indications of external equipment. Thus, external equipment failure may participate in overall fault indication and redundant switchover operation.

Each AUX COMM connector also is capable of supplying power to external LNAs (or other devices). This power supply features current monitoring with programmable failure limits.

Overcurrent and undercurrent failures can participate in overall fault indication and redundant switchover criteria.

Each MBT-4000 base includes two “switch drive” connectors. Each of these connectors is intended for driving and monitoring a 28V latching switch. In most installations, one switch drive connector will drive an RF waveguide switch, while the second switch drive connector will drive an IF(L-Band) coaxial switch.

C.2 Single-Base Redundancy Operation

Single-Base Redundancy Operation is not supported in the MBT-4000.

Figure C-1. Dual-Base (Chain) Redundancy Operation

RX

L-BAND

MODEM

TX

Figure C-1 illustrates a typical Dual-Base (Chain) Redundancy configuration. The two

MBT-4000 base units cooperate in monitoring the health of the four BxCs (and each other). In case of a fault on an online BxC the MBT-4000 base containing the corresponding standby BxC, will automatically switch over to the standby BxC in accordance with the following rules:

1. In dual-base (chain) redundancy operation, the redundancy is ‘slot’ based. The corresponding pairs reside in the same ‘slot’ of the opposite MBT-4000 base, the pair of

BxCs connected to J3 UNIT 1 COMM (Slot 1) on each base form a redundant pair. The

BxCs connected to J6 UNIT 2 COMM (Slot 2) on each base form the other redundant pair. Typically, one pair is used for up conversion and the other for down.

2. The corresponding BxCs in a pair must be of the same type.

3. The Redundancy Interlink Cable (CEFD P/N CA/WR11224-1 or equivalent) must be installed.

4. Base unit identification(MBT-A or MBT-B) is driven by the redundancy interlink cable.

Hard wired connections within the cable designate one MBT-4000 base as MBT-A and the other as MBT-B. The cable is labeled accordingly.

5. The RF and IF switches connected to MBT-A correspond to the redundant pair of BxCs installed on J3 UNIT 1 COMM (Slot 1).

C–2



Revision 4

MN/MBT4000.IOM

6. The RF and IF switches connected to MBT-B correspond to the redundant pair of BxCs installed on J6 UNIT 2 COMM (Slot 2).

7. When a BxC attached to MBT-A is online, the corresponding RF and IF switches will be switched to position A. When a BxC attached to MBT-B is online, the corresponding switches will be switched to position B.

For a switchover to occur:

1. Both MBT-4000 base units must be set to redundancy mode 2, the RED=2 command must have been received by each base.

2. Both BxCs must be set to automatic mode. For example, if the redundant pair is on Slot 2 of the bases, the command RAM=21 must have been received by each base.

3. The corresponding standby BxC must not be in faulted state.

C.4 External Fault Monitoring

Each MBT-4000 base includes two logic inputs, one per AUX COMM connector, that may be connected to contact closure fault indications of external equipment (usually an SSPA or LNA).

Thus, external equipment failure may participate in overall fault indication and redundant switchover operation according to the following rules:

1. An open connection (or 2.7 V min) indicates a fault condition exists.

2. A closed connection (or 0.7 V max) indicates no fault condition exists.

3. Maximum voltage range on fault logic inputs is –12V to +12V.

4. The fault inputs correspond to a slot, the fault input of AUX COM 2 corresponds to the

BxC installed as UNIT 2. The fault input of AUX COM 1 corresponds to the BxC installed as UNIT 1.

5. To enable fault input checking the EFI=nm command is usedwnput parameter ‘n’ can equal 1for AUX COM 1 input, or 2 for AUX COMM 2 input. The mode parameter ‘m’ can equal 0 for disabled, or 1 for enabled. Each input must be enabled individually.

C.5 LNA Power Supply Current Monitoring

The MBT-4000 base and BDC-4000 are capable of supplying power to external LNAs. The

MBT-4000 base supplies the power from a pin in the AUX COMM connectors; the BDC-4000 supplies the power over the center conductor of the coaxial cable. These power supplies feature current monitoring with programmable failure limits. Overcurrent and undercurrent failures can participate in overall fault indication and redundant switchover criteria.

The following commands and rules configure operation of this feature:

1. The power supplies are +12.6V with a 350 mA current limit.

2. No more than two of the four possible supplies should be enabled simultaneously.

3. An individual supply is enabled by issuing the ‘LCS=sm’ command as follows: a. ‘s’ is the source. Valid values are 1 or 2 where: 1=AUX COMM 1 supply and

2=AUX COMM 2 supply. The BDC-4000 only has a single current source, so ‘s’ must be set to 1 on a BDC-4000.

C–3



Revision 4

MN/MBT4000.IOM b. ‘m’ is the mode. Valid values are 0=OFF or 1=ON.

4. In case of excessive current (more than 350 mA), the supply will be disabled and a fault will be posted. The ‘LCS=sm’ command must be sent again to re-enable the supply.

5. To enable programmable current monitoring, the following steps are taken: a. The desired output is enabled as outlined above. b. The nominal current is calibrated using the CLC=s command, where ‘s’ is the source as described previously. c. The programmable current window is specified using the LCW=sxx command.

Where ‘s’ is the source as described previously and ‘xx’ is the allowable percentage of variance from nominal (set by the CLC command). Acceptable values for ‘xx’ are

20 to 50 in increments of 1%. In addition, a value of ‘99’ for ‘xx’ disables the alarm function. d. If a current is detected outside this window, a LNA current fault will be posted, but the supply will not be disabled.

C.6 Gain Equalization of Redundant Units

Gain equalization in an MBT-4000 system is accomplished by issuing individual attenuation settings to the specific BxCs.

C.7 Operational Configuration Commands

In automatic redundancy mode, configuration commands (with the exception of attenuation and

LNA power supply configuration) sent to the online unit will be mirrored in the offline unit. In auto mode, commands sent to the offline unit will be rejected.

In manual mode, configuration commands are not mirrored. However, upon reverting to “auto” mode, online unit configuration will transfer to the offline unit, again with the exception of attenuation and LNA power supply configuration.
