External interface connectors are located on the front and rear panels of the MBT-5003 chassis.
External equipment (e.g., a modem) is connected to each internal converter module via a
standard, off-the-shelf coaxial cable. A coaxial cable is also used to connect the output for each
module to RF equipment either at the same location or at the antenna location.
The system contains two diode “OR-ed” internal power supplies for increased reliability, and
microprocessor-based Monitor and Control (M&C) functions. Particular care has been given to
the RF performance of the MBT-5003 to facilitate its successful use in MIL-STD-188-164A
systems.

Create a temporary folder (directory) on an external PC:
• For Windows Explorer: Select File > New > Folder to create a new folder, then
rename it from “New Folder” to "temp" or another convenient, unused name. Assuming
"temp" works, a "c:\temp" folder should now be created.
Note: The drive letter c: is used in this example. Any valid writable drive letter can be
used.
• For Windows Command-line: Click [Start] on the Windows taskbar, then click the
“Run...” icon (or, depending on Windows OS versions prior to Windows 95, click the
“MS-DOS Prompt” icon from the Main Menu). Then, to open a Command-line
window…

IP Address/ Range menu.
Then, using Command-line to PING: At the Command-line prompt, type “ping
xxx.xxx.xxx.xxx” (where ‘xxx.xxx.xxx.xxx’ is the Management IP address of the unit).
The results should confirm whether or not the unit is connected and communicating.
Initiate an FTP session with the unit (this example uses Command-line):
a) From the PC, type "ftp xxx.xxx.xxx.xxx" where "xxx.xxx.xxx.xxx" is the IP address
of the MBT-5003.
b) Enter the Admin User Name (there will be no prompt for a password) to complete
login.
c) Verify the FTP transfer is binary by typing "bin".
d) Type "prompt", then type "hash" to facilitate the file transfers.
Transfer the files from the temporary folder on the PC:
Type "put FW-0000303x_#_#_#.bin bulk:” to begin the file transfers. The destination “bulk:”
must be all lower-case. Approximately one minute is required to transfer the file.
Verify the file transfer:
a) The PC should report that the file transfer has occurred, and the display on the unit
will start reporting “Programming App Flash … Please wait”. After a few minutes, the
unit will display “Programming main FPGA … Please wait”.
b) Terminate the FTP session by typing "bye" and close the Command-line window.
c) Confirm that the new file was loaded by using the procedure in Step 1.

position. Most of the menus (space permitting) include arrow key hints to guide
the user.
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 frequency or data rate.
5.1.4 Vacuum Fluorescent Display (VFD)
The MBT-5003 features a Vacuum Fluorescent
Display (VFD). The VFD is an active display
showing two lines of 24 characters each. It
produces a blue light, the brightness of which
can be controlled by the user. Compared to a Liquid Crystal Display (LCD), it has greatly
superior viewing characteristics and does not suffer problems of viewing angle or contrast.
On most menu screens, the user will observe a flashing solid block cursor, which blinks at a onceper-second rate. This indicates the currently selected item, digit, or field. Where this solid block
cursor would obscure the item being edited (e.g., a numeric field) the cursor will automatically
change to an underline cursor.
If the user were to display the same screen for weeks at a time, the display could become ‘burnt’
with this image. To prevent this, the unit has a ‘screen saver’ feature, which will activate after a
few minutes. The top line of the VFD will display the Circuit ID, and the bottom line will display
‘Press any key...’. The message moves from right to left across the screen, then wraps
around. Pressing any key will restore the previous screen.

The sections that follow describe the functionality of the MBT-5003 Ethernet Interface. Refer to the
Remote Commands Specifications tables found in Appendix A. REMOTE CONTROL for
detailed descriptions of the configuration parameters featured on the individual Web pages depicted
in this section.
6.2 Ethernet Management Interface Protocols
The MBT-5003 100BaseT/10BaseTx Ethernet Management Interface supports three (3) different
management protocols:
• SNMP with public and private MIB
• Telnet interface for remote product M&C
• Web Server (HTTP) Interface for complete product management
For SNMP, Telnet, or Web Server operation, the MBT-5003 must be configured
with the Ethernet control option. Via the front panel, select CONFIG: Remote
IMPORTANT
Control Æ Ethernet. See Chapter 5. FRONT PANEL OPERATION for further
information.
6.3 SNMP Interface
The Simple Network Management Protocol (SNMP) is an application-layer protocol designed to
facilitate the exchange of management information between network devices. The MBT-5003
SNMP agent supports both SNMPv1 and SNMPv2c.
For proper SNMP operation, the MBT-5003 MIB files must be used with the
associated version of the MBT-5003 M&C. Refer to the MBT-5003 FW Release

MBT-5003 L-Band Up/Down Converter System Revision 1
Ethernet Management MN-MBT5003
6.3.1 Management Information Base (MIB) Files
MIB files are used for SNMP remote management and consist of Object Identifiers (OIDs). Each
OID is a node that provides remote management of a particular function. A MIB file is a tree of
nodes that is unique to a particular device.
The following MIB files are associated with the MBT-5003:
MIB File/Name Description
FW-0000235-.mib
ComtechEFData
Root MIB file
FW-0000101- .mib
MBT-5003 MIB file
FW-0000102- .mib
MBT-5003 Traps
MIB file
ComtechEFData MIB file gives the root tree for ALL Comtech EF Data products
and consists of only the following OID:
Name: comtechEFData
Type: MODULE-IDENTITY
OID: 1.3.6.1.4.1.6247
Full
path: iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).comtechEFData(6247)
Module: ComtechEFData
MIB file consists of all of the OID’s for management of the amplifier functions
Trap MIB file is provided for SNMPv1 traps common for MBT-5003.
These MIB files should be compiled in a MIB Browser or SNMP Network Monitoring System server.
Note: As noted previously, the SNMP agent supports both SNMPv1 and SNMPv2c. The
“Traps” file only needs to be compiled if SNMPv1 traps are to be used.
6.3.2 SNMP Community Strings
The MBT-5003 uses community strings as a password scheme that provides authentication before
gaining access to the MBT-5003 agent’s MIBs.
In SNMP v1/v2c, the community string is sent unencrypted in the SNMP packets. Caution must
be taken by the network administrator to ensure that SNMP packets travel only over a secure and
private network if security is a concern. A packet sniffer can easily obtain the community string
by viewing the SNMP traffic on the network.
The community string is entered into the MIB Browser or Network Node Management software
and is used to authenticate users and determine access privileges to the SNMP agent.
The user defines three Community Strings for SNMP access:
• Read Community default = public
• Write Community default = private
• Trap Community default = comtech

6.3.3 SNMP Traps
The MBT-5003 has the ability to send out SNMP traps when certain events occur in the unit. The
MBT-5003 sends out traps when a fault occurs in the unit. A trap is sent both when a fault occurs
and is cleared.
The MBT-5003 supports both SNMPv1 traps and SNMPv2 notifications. Which style of traps
the MBT-5003 sends can be configured by the user using the MBT-5003SNMPTrapVersion OID.
The following are the MIB2 v1traps / v2 notifications that the MBT-5003 supports:
MIB2 SNMPv1 trap: Authentication Failure 5
MIB2 SNMPv2 notifications: Authentication Failure 1.3.6. 1.6.3.1.1.5.5

6.4 Telnet Interface
The MBT-5003 provides a Telnet interface for the purpose of Equipment M&C via the standard
equipment Remote Control protocol.
The Telnet interface requires user login at the Administrator level and Read/Write level.
The example shown to the
right illustrates the login
procedure:
Once logged into the
Telnet interface as
Administrator, the user can
access the standard remote
control interface defined in
Appendix A. REMOTE
CONTROL, as shown in
example to the right:
There is a disadvantage when using Windows DOS as Telnet Client. Since Windows DOS cannot
translate a ‘\r’ to a ‘\r\n’ for the messages coming from Telnet Server, the multi-line command
response (for example, FRW? response) will be displayed as one line, with the latt er lines ove rwriti ng
the previous lines. In order to view the full response messages, CEFD recommends using
HyperTerminal configured as Telnet Client.
Configure HyperTerminal as follows:
1. Use TCP/IP (Winsock)
nstead of COM1 or COM2 for
the connection, as per the
example to the near right.

A.1 Introduction
This appendix describes the protocol and message command set for remote monitor and control of the MBT-5003 L-Band Up/Down
Converter System.
The electrical interface is an EIA-485 multi-drop bus for the control of many devices, 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.
The Remote Control connector pinout is shown in Chapter 3.2.6 COM (EIA-485 Interface), J3 (DB-9F).
NOTE
A.2 EIA-485
For applications where multiple devices are to be monitored and controlled, a full-duplex (4-wire plus ground) EIA-485 is preferred. Halfduplex (2-wire plus ground) EIA-485 is possible, but is not preferred. In full-duplex EIA-485 communication, there are two separate,
isolated, independent, differential-mode twisted pairs, each handling serial data in different directions.
Appendix A. REMOTE CONTROL
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 linedriver connected to this pair; the Target devices have only line-receivers connected.
A–1
MBT-5003 L-Band Up/Down Converter System Revision 1
Appendix A MN-MBT5003
In the other direction: On the other pair, each Target has a tri-state line driver connected; 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; 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.
EIA-485 (full duplex) summary:
• Two differential pairs - one pair for Controller-to-Target, one pair for Target-to-Controller.
• Controller-to-Target pair has o ne line driver (C ontrol ler), a nd all Ta rgets have line- receivers .
• Target-to-Controller pair has one line receiver (Controller), and a ll Targets have tri-state drivers.
A.3 Basic Protocol
With EIA-485 mode, all data is transmitted as asynchronous serial characters, suitable for transmission and reception by a UART. The
asynchronous character format is 8-N-1 (8 data bits, no parity, one stop bit). The supported baud rates are 2400, 4800, 9600, 19200, and
38400 baud.
All data is transmitted in framed packets. The Controller is assumed to be 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 cha nge th e configurat ion of the Target.

body of the message.
A–3
MBT-5003 L-Band Up/Down Converter System Revision 1
Appendix A MN-MBT5003
A.4.2 Target Address
Up to 9,999 devices can be uniquely addressed; in EIA-485 applications, the permissible range of values is 1 to 9999. The address is
programmed into a Target unit using the remote control port.
Each block converter module has its own address:
Module Address
MBT-5003 Base
Block Converter A Base + 1
Block Converter B Base + 2
If several devices share an EIA-485 bus, it must be noted that the MBT-5003 will require three addresses, and should be spaced apart
accordingly.
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
IMPORTANT
Controller does not have its own address.
A.4.3 Address Delimiter
This is the “forward slash” character '/' (ASCII code 47).
A.4.4 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. For example,
FRE is for Operating FREquency,
FBU is for Force Backup Unit, etc.
This aids in the readability of the message if seen in its raw ASCII form. Upper case and lower case alphabetic characters may be used (AZ and a-z, ASCII codes 65 – 90 and 97-172).
A–4
MBT-5003 L-Band Up/Down Converter System Revision 1
Appendix A MN-MBT5003
A.4.5 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 ‘=’ and ‘?’:
=
(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) which follow it.
For example, in a message from controller to target, MUT=1 would mean ‘enable the mute function’.
The ? code 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, in a message from controller to target, MUT? denotes ‘return the current state of the mute function.’
2. From Target-to-Controller, the only permitted values are ‘=’, ‘?’, ‘!’, ‘*’, ‘#’, a nd ‘$’:
=
(ASCII code 61)
?
(ASCII code 63)
!
(ASCII code 33)
The = code is used in two ways:
First, if the controller has sent a query code to a ta rget (for example: MUT? meaning 'is mut e e nab le d or d isabled ?'), th e targ et
would respond with MUT=x, where x represents the state in question: 1 being enabled, and 0 being disabled.
Second, if the controller sends an instruction to set a param eter 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 follow s:
If the controller sends an instruction to set a parameter to a particular value, then, if the value sent in the argu ment is not vali d,
the target will acknowledge the message by r eplying (for example) with MUT? (without 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 t he target does not recognize, the target will acknowledge the message by
echoing the invalid instruction, followed by the ! character with. Example: XYZ!
*
(ASCII code 42)
The * code is only used as follows:
If the controller sends an instruction to set a parameter to a particular value, and, if the value sent in the argument is vali d,
however the target is in the wrong mode (for example, standby mode in redundancy configuration) that it will not permit that
particular parameter to be changed at that time, then the target will acknowledge the message by replying (for example)
with MUT* (without message arguments).
A–5
MBT-5003 L-Band Up/Down Converter System Revision 1
Appendix A MN-MBT5003
#
(ASCII code 35)
$
(ASCII Code 36)
The # code is only used as follows:
If the controller sends an instruction code which 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. This response
can only occur if the operator sends two or more ‘hardware configuration’ type commands without allowing adequate time
between commands for the hardware to be configured. For example, if the operator issued commands to change both the
frequency and the attenuation with less than 100 milliseconds between commands, and if this response is returned, then
the command has not been accepted and the operator must resend the command.
The $ code is only used as follows:
The target acknowledges the message indicating that this block converter is not installed.
A.4.6 Optional Message Arguments
Arguments are not required for all messages. Arguments are ASCII codes for the characters 0 to 9 (ASCII codes 48 to 57), period (ASCII
code 46), and comma (ASCII code 44).
A.4.7 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 code 13, and ASCII code 10).
Both indicate the valid termination of a packet.
A.5 Configure Mute Mode
Turns the mute mode ON or OFF. When mute mode is OFF (default), the unit will mute upon changing RF frequency. When mute mode
is ON, the unit will remain whatever its mute state upon changing RF frequency.
Command Details
Configure Mute Mode: <DEV/MUT=y'cr' DEV = Conv A or Conv B address, y = 0 or 1
Confirmation: >DEV/MUT='cr''lf'
Mute Mode Status: <DEV/MUT?'cr'
Confirmation: >DEV/MUT=y'cr''lf'

Command or Query.
The BUC/BDC output will automatically be muted in the event of
detected fault. If auto fault recovery is enabled, it will cause the
output return to its pre-fault mute condition if all faults are cleared.
If disabled, the output will remain muted even if all faults are
cleared.
The clearing of the fault condition will not cause a switch over in a
redundant system unless the currently online unit is faulted. In
which case the newly un-faulted unit will be brought online.
Default Value: 1
Example: <1/AFR=1’cr’
>0001/AFR=’cr’’lf’

There could be a variable delay in the time it takes for the internal
reference to lock to an external reference, due warm-up
characteristics and frequency differences between the references.
Therefore, the default setting is "masked" for the reference lock
detect. This setting may be changed if the customer so desires.
The delay should be less than 1 s after 30 minutes of warm-up
time.

B.2 Redundant Operation
Refer to Appendix A. REMOTE CONTROL for further information about the remote commands
mentioned in this section.
B.2.1 Auto Mode
In this mode, one converter is always online (determined by the switch position and indicated on
the fro nt p anel), and the other converter is always offline and muted. If a fault is detected on the
online converter, either by loss of communications between the base unit and the online
converter, or via the summary fault, the base unit will switch the RF and IF switches and the
offline converter then become the active (online) unit (assuming the offline unit is not faulted).
B.2.2 Force Switchover
The online converter can be forced to become the offline unit (assuming the offline unit is not
faulted) either via the remote command (RED) or by front panel operation (
FORCE).
CONFIG ► REDUN ►
B.2.3 Gain Equalization of Redundant Units
Both converters are temperature compensated at same gain level, so the gain will stay the same
during a switchover.
B.2.4 Operational Configuration Commands
The attenuation command (ATT) sent to the online u nit will be mirrored in the offline unit. The
commands sent to the offline unit will be rejected.
