3.3 REMOTE OPERATIONS
The equipment is supplied with an RS485/RS422 bus interface or, as an option, with RS232,
IEEE-488 or Ethernet TCP/IP. The command structures for the serial buses are identical.
17
3.4 SERIAL REMOTE PROTOCOL (RS485/RS422/RS232)
The command structures for the serial buses; RS485, RS422 and RS232 are identical. All
transmissions are multi-byte sequences beginning with a header byte and ending with a trailer
byte and checksum byte. The transmitted bytes are all ASCII printable characters in the range
of 20H to 7EH.
Serial data format is a 10-bit sequence consisting of 1 Start, 7 Data, 1 Parity, and 1 Stop bit. All
characters, including the checksum character, are checked for parity. If any character in a
command message contains an error (parity, framing or overrun) or the checksum is incorrect,
the command is ignored and no response is made. The remote parameters: Address, Baud
Rate, and Parity are programmable from the front panel. The response time from command to
acknowledge is 100 ms. maximum.
All messages addressed to the equipment are acknowledged with a response message. The
unit continually monitors the communication bus and will accept commands, addressed to it,
even in Local mode. When in Local mode, receipt of any SET commands (commands
beginning with “$”) will be ignored and the unit will respond with an error code.
The response time from command to acknowledge is 100 ms. maximum. Since all bytes are
ASCII printable characters, a compatible terminal may be used to control the equipment or
monitor traffic on the communication bus.
3.4.1 SERIAL MESSAGE FORMAT
The Serial Message Format is as follows:
HEADER - ADDRESS - COMMAND/ERROR CODE - PARAMETERS - TRAILER –
CHECKSUM
The Header byte is 7BH, ASCII character "{".
The address may take on the values from 64 to 95 decimal (40H to 5FH).
Commands are three ASCII characters preceded by an ASCII “?” or “$.” Commands preceded
by “?” are QUERY commands and those preceded by “$” are SET commands. Query
commands are used to examine system parameters while SET commands are intended to
modify system parameters.
Parameters are all ASCII printable characters in the range of 20H to 7EH. Numeric parameters
are sent MSD first, LSD last. Values which do not adhere to the command format, or are
beyond the allowable range, will be rejected and cause the unit to respond with an error code.
The Trailer byte is 7DH, ASCII character "}".
The checksum byte is the sum modulo 95 of all message characters beginning with the header
byte up to and including the trailer byte. The value 32 is subtracted from each character value
before taking the modulo 95 sum. The value 32 is added to the final sum to obtain the
checksum value. All values are in decimal.
Checksum = MOD [(character value - 32), 95] + 32
18
Below is a program, written in the ‘C’ programming language that illustrates the checksum
calculation.
char check_sum(char*,char);
char check_sum(array,mes_len)
/* return the checksum character for the message in array */
/* subtract 32 from each character before taking modulo 95 sum */
/* add 32 to the final sum */
/* mes_len = message length */
char array[32],mes_len;
{
char i,sum;
sum = 0;
for ( i = 0; i < mes_len; i++ ) {
sum = sum + ( array[i] - 32 );
if ( sum >= 95 ) sum = sum - 95;
}
return(sum + 32);
}
3.5 IEEE-488 MESSAGE PROTOCOL
The equipment performs the basic Talker and Listener functions as specified in the IEEE-488
standard. It is also capable of sending a Service Request to the active IEEE-488 controller and
will respond with a status word when the Serial Poll Enable message is received.
The messages to and from the unit are ASCII character strings terminated with CR, LF and EOI.
The response time from command to acknowledge is 100 ms. maximum.
3.5.1 IEEE-488 MESSAGE FORMAT
The IEEE-488 message format is as follows:
COMMAND CODE - PARAMETERS
Commands are three ASCII characters preceded by an ASCII “?” or “$.” Commands preceded
by “?” are QUERY commands and those preceded by “$” are SET commands. QUERY
commands are used to examine system parameters while SET commands are intended to
modify system parameters.
SET commands do not affect the unit’s response when it is addressed to talk by the IEEE-488
controller.
QUERY commands determine the unit’s response when it is addressed to talk by the IEEE-488
controller. The context of the unit’s response remains in effect until another QUERY command
is received. The response to the Alarm Status Query command (?ALR) is in effect at power up
as the default format.
Parameters are all ASCII printable characters in the range of 20H to 7EH. Numeric parameters
are sent MSD first, LSD last. Values that do not adhere to the command format, or are beyond
the allowable range, will be ignored.

3.7 ETHERNET OPERATION WITH OPTION 17H
3.7.1 FUNCTIONAL DESCRIPTION
The MITEQ 9800/9900 Series Converter can be equipped with an Ethernet Interface (Option
17H) feature permitting control and monitoring via a 10 or 100 Mbps Ethernet connection.
Available interface protocols are HTTP (web access), SNMP (Simple Network Management
Protocol), and Telnet. In addition, a capability to remotely upgrade the Ethernet firmware is
provided.
The use of standard protocols makes it possible to provide (password-protected) access to the
converter from any location in the world where an internet connection is available
3.7.2 ETHERNET SETUP
Connection The Converter must be connected to the facility Local Area Network (LAN) network via an
industry-standard 10baseT RJ45 cable. The cable should be a “direct” cable, not a “crossover”
cable. The Converter may also be connected directly to a PC without a LAN. (See below for
details).
Setup Setup of the Ethernet Interface should be attempted only after the Converter is fully installed
and functioning. Once operating, the Ethernet Interface may be configured.
Configuring Internet Protocol (IP) Operating Parameters An Internet Protocol (IP) address and associated parameters must be configured in the unit so
the controlling device can address it. Normally, the individual or organization managing the
facility’s LAN assigns this address. (See below for information on connecting directly to a PC
without a Local Area Network). Three parameters will be required:
IP Address
Subnet Mask
Gateway
(Factory setting 192.168.1.1)
(Factory setting 255.255.255.0)
(Factory setting 192.168.1.0)
Note: Factory setting IP address is assigned at time of final testing of the converter. The
default IP is recorded on the Final Test Data Sheet for the unit. Unique MAC addresses are
provided and recorded on the basis of serial number at MITEQ.
The Ethernet IP address can be configured via the local interface see Section 3.2.4.
Verifying Proper Connection and Configuration The connection and configuration may be verified from a PC attached to the LAN using the
network “ping” command. From a command prompt, enter “ping <assigned IP address>”
The response will indicate whether a connection was established.
32
3.7.3 ACCESSING THE SYSTEM
Access via the Web Interface
All system settings may be may be queried or modified via the Web Interface. The web page
designs have been optimized for the use with the Microsoft Internet Explorer (MSIE) Version 5.0
web browser, or higher. Use of Cookies must be enabled (see the TOOLS|INTERNET

Access via SNMP The Converter may be accessed and monitored via the Simple Network Management Protocol
(SNMP). SNMP is designed for control of network elements from a central management point.
The SNMP Management Information Base (MIB) file for the system, available from MITEQ
defines the specifics of the interface. The MIB file is read by the SNMP management tool and
will provide an “understanding” of the interface. The MIB file is in a format that can be ready
with any text editor. Do NOT modify this file.
SNMP operating parameters may be set on the COMMS web page. If SNMP operation is not
desired, this feature may be rendered inaccessible by inserting a long arbitrary string in the
Read Community and Write Community fields.
Access via Telnet The Converter may be accessed via Telnet. There is no special protocol on the Telnet channel;
the Converter will expect the same commands, and offer the same replies, as via the serial port.
Telnet access must first be enabled on the COMMS web page. If not being used, it is
recommended that it be left disabled for security reasons.
When a Telnet connection is established, the Converter will request the password, which should
be sent in the standard MITEQ wrapper (‘{‘<address byte (ignored)><password>’}’<checksum
byte>). The connection will be refused if a user is already logged in via the web interface.
Once the connection is established, standard serial commands may be sent and responses will
be received. Logout is automatic when the Telnet connection is broken.
3.7.4 ETHERNET FIRMWARE UPGRADE
Should it become necessary to upgrade the Ethernet firmware onboard the Converter, a file will
be provided by MITEQ for this purpose. Firmware upgrade is accomplished via File Transfer
Protocol (FTP). Numerous FTP client programs are available, or MSIE may be used for this
purpose. If MISE is being used, be sure to enable the FTP feature on the TOOLS|INTERNET
OPTIONS|ADVANCED page.
Firmware Upgrade must be enabled on the MISC web page before beginning. Once it is set,
connect to the Converter via FTP. If using MSIE, enter the command:
“ftp://<assigned IP address>”
The user will be prompted for a user ID and password. The user ID is always “MITEQ”, and the
password will be the assigned system password viewable from the local interface.
No files will be visible in the FTP server directory. Upload the file provided (if using MSIE, by
dragging and dropping into the IE window), and wait for the upload to complete. The file will
NOT be visible in the FTP file name list or window after loading. The firmware upgrade will
begin when the FTP connection is broken, and may take as long as 15 seconds, during which it
will be impossible to connect to the Converter.
After the upgrade, it will be necessary to log in again. The new firmware version will be visible
on the login page.

Connecting Without a Network For testing, familiarization, or configuration, the Converter may be connected to a PC without a
LAN. This may be done two ways:
•
•
Connect via an Ethernet hub, using standard cables
Connect directly using a single, reversing cable
In this configuration, the PC must be configured with a Static IP address. The procedure for this
varies between OS types and versions. Consult the operating manual or help files available
with the computer to be used to determine the proper procedure.
The computer must be configured with the same Subnet Mask, but a different IP address, to
connect properly. For connecting with the converter as shipped from the factory, the following
settings are recommended:
IP Address
Subnet Mask
Gateway
192.168.1.2
255.255.255.0
192.168.1.0
Note: Factory setting IP address is assigned at time of final testing of the converter. The
default IP is recorded on the Final Test Data Sheet for the unit. Unique IP addresses are
provided and recorded on the basis of serial number at MITEQ.
Both standard and reversing cables are widely available. The following chart is provided for
assembling cables if desired, or for identifying a specific cable type:

Reaching the Converter By NAME Instead of IP Address If the Converter is connected to a LAN equipped with a Domain Name Server, the network
manager may be able to configure the server to associate a particular text name with an IP
address. If this is not the case and addressing by name is desired, machines equipped with
Microsoft Windows may be configured for this capability.
Locate the “hosts” file on the PC to be configured. Some common locations for the host’s file
are:
Windows XP:
Windows 2K:
Win 98\ME:
C:\WINDOWS\SYSTEM32\DRIVERS\ETC
C:\WINNT\SYSTEM32\DRIVERS\ETC
C:\WINDOWS
The hosts file is a plain-text file of the form:
<ip address> <associated name>
Add the desired address/name pair(s) to the list. Generally, it is a good idea to back up any
system file before modification. An example host file is provided here:
216.239.39.99
127.0.0.1
192.168.1.1
192.168.1.2
google.com
localhost
miteq9800_1
miteq9800_2
In some cases, it may be necessary to reboot the PC before changes to the host file take effect.
Other operating systems may use a different mechanism. Consult the appropriate
documentation to change host settings.

Controlled-impedance cable used for Ethernet wiring.
An Ethernet cable wired with the signal pairs reversed, to
permit connection of two computer devices.
An Ethernet cable wired with the signal pairs directly
connected, to permit connection between a computer and
hub or router.
File Transfer Protocol, a protocol for moving files between
computers via a TCP/IP connection.
An IP setting parameter that indicates how a device may
connect to other devices that are not a member of the
immediate sub-network.
Hypertext Transport Protocol. The standard protocol for
moving web pages between servers (e.g. the Converter)
and clients (e.g. the web browser).
A component used to connect several Ethernet-equipped
devices together.
Internet Protocol address. A unique address used to
identify and connect to a device.
Local Area Network. A means (usually, but not always
Ethernet) for connecting multiple computing devices
together for high-speed communications.
Internet Protocol. Specifies an organization of data
packets sent between computers for network
communications.
Microsoft Internet Explorer, the web browser integrated
with most versions of Microsoft Windows. The Converter
interface design was optimized for operation with MSIE 5.0
or higher.
The standard telephone-style connector used for
terminating twisted-pair Ethernet cables.
Simple Network Management Protocol, a system of
communication between managed network elements (e.g.
the Converter), and a network control program, e.g. HP
Openview.
A numeric mask defining the size of a subnetwork. Bits
cleared in the mask define IP addresses that may
communicate on the subnetwork.
Transmission Control Protocol. Specifies a mechanism for
establishing a virtual connection between network
elements, usually via IP.
A simple mechanism for communicating between two
devices via TCP. A connection is opened between the
devices, and bytes may then pass freely between them, as
with a serial connection.

3.8 AUXILIARY CONTROL INTERFACE OPERATION (RS485/RS422)
An additional RS485/RS422 serial port has been provided to support ancillary system functions.
This port can be used to connect to the MITEQ NSU Series 1:N Redundancy Switchover
Systems leaving the remote port available for direct connection to a conventional monitor and
control (M&C) system. Another use for this port is to support applications where both remote
control from a MIMIC panel as well as an M&C system is required. An additional application is
available for upconverters. This port can be used to control an external high-powered amplifier
(HPA). This is useful when rack space is at a premium, eliminating the need for a dedicated
controller for the HPA. The command structures for the Auxiliary Control Interface are identical
to those described in the RS485/RS422 Remote Operation section of this document. Refer to
MITEQ Technical Note 25T061 for commands that apply to HPA control specifically.
