Functional Description
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. When configured with the redundancy option, the system may contain two diode “OR‐ed” internal power supplies for increased reliability, and microprocessor‐based Monitor and Control (M&C) functions. Figure 1‐4 depicts the block diagram for a typical LBC‐4000 L‐Band Up/ Downconverter System application. Figure 1-4. LBC-4000 Typical Application Block Diagram

connected to the protective earth connection at all times. It is therefore
imperative that the unit is properly grounded, using the ground stud provided
on the unit rear panel, during installation, configuration, and operation.
•
PROPER AIR VENTILATION IS REQUIRED. In a rack system where there is
high heat discharge, provide forced-air cooling with top- or bottom-mounted
fans or blowers.
o
Make sure there is adequate clearance inside the enclosure, especially
at the side for air ventilation.
o
Air temperature inside the rack enclosure should never exceed 50°C
(122°F).

The LBC‐4000 firmware download hyperlink appears as F9965X_V####, where ‘X’ denotes the revision letter, and ‘####’ represents the firmware version (e.g., V1116 = Version 1.1.16). • About File Archive Formats: Comtech EF Data provides its downloadable files in two compressed archive formats: *.exe (self‐extracting) and *.zip (compressed). The *.exe file does not require a 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. Some firewalls do not allow the download of *.exe files. Download the *.zip file instead, and extract the firmware files from the archive download with a user‐supplied utility program. For detailed information on handling archived files, refer to the utility program Help documentation. G. Download the archive file to the temporary folder. • Once the EXE or ZIP hyperlink is selected the ‘File Download’ window opens and prompts selection of [Open] or [Save]: 4–5

Chapter 6. SERIAL-BASED REMOTE PRODUCT
MANAGEMENT
6.1
Introduction
Serial‐based Remote Product Management of the LBC‐4000 L‐Band Up/Down Converter System is available using the rear panel ‘J1 COM1’ port. This interface is either an EIA‐485 multi‐drop bus (for the control of many devices) or an EIA‐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. 1. To proceed with Serial‐based Remote Product Management, assumptions are made that: •
The LBC‐4000 is operating with the latest version firmware files. The LBC‐4000 is connected to a user‐supplied Windows‐based PC as follows: o The PC’s serial port is connected to the LBC‐4000 rear panel ‘J1 | COM1’ port with a user‐supplied serial cable. o The PC is running a terminal emulation program (for operation of the LBC‐4000 serial remote control interface). •
2. See Chapter Sect. 3.2.2.3 J1 | COM 1 (EIA-485/232) Interface Connector (DB-9F) for the serial interface connector
pinout information.

EIA-485
For applications where multiple devices are to be monitored and controlled, a full‐duplex (4‐wire plus ground) EIA‐485 is preferred. Half‐
duplex (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. 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‐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. o The Controller‐to‐Target pair has one line driver (Controller), and all Targets have line‐receivers. o The Target‐to‐Controller pair has one line receiver (Controller), and all Targets have Tri‐state drivers. 6.1.2
EIA-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 EIA‐232 electrical levels, on one conductor, and Target‐to‐Controller data is carried in the other direction on the other conductor. 6–2

Remote Commands and Queries Overview
6.2.1
Basic Protocol
Revision 4
MN/LBC4000.IOM
Whether in EIA‐485 or EIA‐232 mode, all data is transmitted as asynchronous serial characters, suitable for transmission and reception by a UART. The default asynchronous character format is 8‐N‐1 (8 data bits, no parity, one stop bit). The supported baud rates are 1200, 2400, 4800, 9600, 19K2 (19200), or 38K4 (38400) bps. All data is transmitted in framed packets as asynchronous serial characters, suitable for transmission and reception to the Controller using a universal asynchronous receiver/transmitter (UART). Controller‐to‐Target data is carried via EIA‐232 electrical levels on one conductor, and Target‐to‐Controller data is carried in the other direction on the other conductor: • Controller‐to‐Target – The Controller device (e.g., the user PC) is used to transmit instructions (commands) to – or to request information from (queries) – the Target device (i.e., the LBC‐4000). • Target‐to‐Controller – The Target, in return, only transmits response information to the Controller when specifically directed by the Controller. For Serial Remote Control, all issued commands (Controller‐to‐Target) require a response (Target‐to‐Controller). This response is either to return data that has been queried by the Controller, or to confirm the Target’s receipt of a command to change the Target’s configuration. 6.2.2
Packet Structure
The exchange of information is transmitted, Controller‐to‐Target and Target‐to‐Controller, in packets. Each packet contains a finite number of bytes consisting of printable ASCII characters, excluding ASCII code 127 (DELETE). 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 EIA‐485 mode. 6–3

MN/LBC4000.IOM
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
LBC-4000
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 LBC‐4000 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 Controller does not
have its own address. 6.2.2.3
Address Delimiter
This is the “forward slash” character '/ ' (ASCII code 47). 6.2.2.4
Instruction Code
This is a three‐character alphabetic sequence that identifies the message subject. Wherever possible, the instruction codes have been chosen to have some significance – e.g., FRE for Operating FREquency, IPA for Management IP Address, etc. This aids in the readability of the message, should it be displayed in its raw ASCII form. Upper case and lower case alphabetic characters may be used (‘A’ to ‘Z’ and ‘a’ to ‘z’, ASCII codes 65‐90 and 97‐172). 6–5

Instruction Code Qualifier
This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules: From Controller‐to‐Target, the only permitted characters are: Character
Definition
=
(ASCII code 61)
This character is used as the Assignment Operator (AO). It establishes that the Instruction Code that precedes it is to
be used as a command to assign or configure operation. The instruction set that follows serves to assign the Target’s
new parameter setting or operational value.
Example: From Controller-to-Target, MUT=1 means “enable the mute function.”
?
(ASCII code 63)
This character is used as the Query Operator (QO). It establishes that the Instruction Code that precedes it is to be used
as a query that returns the Target’s current configured parameter setting or operational value.
Example: From Controller-to-Target, MUT? means “what’s the current state of the MUTE function?”
From Target‐to‐Controller, the only permitted characters are: Character
Definition
=
(ASCII code 61)
This character is used in two ways:
a. If the Controller sends a query to the Target – for example: MUT? meaning “what’s the current state of the MUTE function?”, the
Target would respond with MUT=x, where x represents the state in question: 1 being enabled, and 0 being disabled.
b. If the Controller sends an instruction to set a parameter to a particular value, and the value sent is valid, the Target acknowledges
the message and responds with MUT= (with no message arguments).
?
(ASCII code 63)
If the Controller sends an instruction to set a parameter to a particular value, and the value sent is not valid, the Target then
acknowledges the message and responds with, for example, MUT? (with no message arguments). This indicates that there was an
error in the message sent by the Controller.
!
(ASCII code 33)
If the Controller sends an instruction code that the Target does not recognize, the Target responds by echoing the invalid instruction,
followed by !
Example: XYZ!

Character
Definition
*
(ASCII code 42)
If the Controller sends the command to set a parameter to a particular value, and the value sent is valid BUT the router will not permit
that particular parameter to be changed at present, the Target acknowledges the message and responds with, for example, MUT* (with
message arguments).
#
(ASCII code 35)
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.
$
(ASCII code 36)
The Target acknowledges the message indicating that this block converter is not installed.
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). 6.2.2.7

End of Packet
Controller‐to‐Target – This is the ‘Carriage Return’ ([CR]) character (ASCII code 13). Target‐to‐Controller – This is the two‐character sequence ‘Carriage Return’, ‘Line Feed’ ([cr][lf]) (ASCII codes 13 and 10). Both indicate the valid termination of a packet. 6–7

Introduction
The LBC‐4000 L‐Band Up/Down Converter System can optionally be configured for redundant system operation. This appendix provides detailed information for cabling and otherwise configuring the LBC‐4000 for 1:1 redundancy. B.2
Redundancy Operations Overview
•
Figure B‐1 provides a functional schematic for LBC‐4000 redundant operation. •
Figure B‐2 illustrates the cabling requirements for redundant operation. Note the following: o
o
BNC connections, where applicable, use 50Ω BNC male‐to‐male cables. It is recommended that all Type ‘N’ to Type ‘SMA’ cable connections are best accomplished using a Type ‘N’ male to Type ‘SMA’ female adapter, then using Type ‘SMA’ female‐to‐female cables.
•
Sect. B.3 addresses the control and configuration of an LBC‐4000 Redundancy System via the LBC‐4000 front panel. •
Sect. B.4 addresses the control and configuration of an LBC‐4000 Redundancy System via serial remote control. B–1

Gain Offset is set at installation only. In operation, the normal attenuation setting should be used. The procedure to set the Gain Offset parameters for redundant operation is as follows: Step
Task
1
Monitor output signal level on power meter / spectrum analyzer.
2
Enable Redundancy on converter (CONFIG: REDUND Æ STATE=Enable).
3
Put converter into “Manual” Redundancy Mode (CONFIG: REDUND Æ MODE=Manual).
