RI  
ERR  
RCV - This LED blinks when data is being received, on for a space, off for a mark. The state of this  
RCV LED matches that of the RCV circuit on Pin 3 of the RS232C/V.24 interface.  
XMT - This LED blinks when data is being transmitted, on for a space, off for a mark. The state of  
this LED matches that of the XMT circuit on Pin 2 of the RS232C/V.24 interface.  
CO - This LED lights when a valid carrier tone has been detected.  
56 - This LED is lit when the modem connects using V.92 protocol. The actual connection speed  
depends on ISP server capabilities and line conditions.  
33.6 - This LED is lit when the modem is connected at 33,600 bps. Note that when both 33 and 14  
LEDs light, modem is in 16,800 to 33,600bps mode of operation.  
14.4 - This LED is lit when the modem is connected at 14,400 bps.  
OH - This LED is lit when the phone line is “off hook”. This occurs when the modem is dialing, on  
line, or answering a call. The LED also flashes when the modem is pulse dialing in the  
Command Mode.  
DTR - When the DTR LED is lit, the modem is permitted to answer an incoming call. When DTR  
goes off, a connected modem disconnects if dependent on DTR. The state of this DTR LED  
matches that of the DTR circuit on Pin 20 of the RS232C/V.24 interface.  
RI - This LED is lit during the ringing interval as an incoming call is received.  
ERR - When the ERR LED is flashing, the leased line is down and the modem is in self-test mode  
has failed. When ERR LED is on, this indicates the modem is in an out of service (OOS) state.  
When the modem is out of service, it is busy to incoming calls.

The sixteen DIP-Switches and berg jumper control various modem options or set default values for the  
MT5600BR-V92 Command mode. There is a difference in how several of the switches operate depending  
on whether you are in synchronous or asynchronous mode (DIP-Switch #12).  
Most communications software packages have installation procedures of their own, which call for certain  
modem DIP-Switch settings. If you are using such a package, follow the software's instructions.  
DIP-Switch Settings  
The vast majority of installations are similar, with the MT5600BR-V92 being used to dial up a remote  
installation where the call is automatically answered. The factory default DIP-Switch settings are based  
on this assumption. The following is a brief description and summary of the MT5600BR-V92's DIP-Switch

OOS (Busy Out) Toggle Switch  
The MT5600BR-V92 contains a two-position OOS switch on the front panel. This switch can be used to  
create a “busy out” (OOS) condition for the modem (i.e., take the modem off-hook). To place a modem in  
the Busy condition, move the OOS toggle switch to the (BUSY) position. The modem then goes off-hook,  
its OOS and OH LEDs light, and incoming calls to this modem get a busy signal. If you suspect a problem  
with a particular modem, you can use the BUSY switch to have an optional device (such as a “hunt  
group”) that looks for a non-busy line to perform a “roll over” to the next available modem while you check  
the status of the Busy modem.  
Out of Service/Test Jumper  
When the MT5600BR-V92 is Out Of Service (OOS), it is busy to incoming calls. In the Test (default)  
setting, the modem drives pin 25 high when the modem is in Test mode. In the OOS (optional) setting, the  
computer or terminal forces pin 25 high and puts the modem in a busy condition. Note that jumper  
(shorting) plugs are not shipped with the MT5600BR-V92, but is provided by Multi-Tech’s Tech Support  
group on request.

Dial-Up and Leased Lines  
Connection to the phone system is made via RJ11 type jacks such as an RJ11C or RJ11W. It can also  
be connected to an analog RJ41 or an RJ45S jack, but would not use these jack's digital dB-level  
programming features. The MT5600BR-V92 is designed to transmit at a permissive level of -11dB.  
To connect the modem to the phone lines, one end of the RJ11 cable that is provided with the modem  
plugs into the RJ11 connector located on the back plane of the modem rack and the other end into the  
phone-company-provided RJ11 or RJ11W modular phone jack. Make sure that DIP-Switch #10 is in the  
UP position (default) when in dial-up mode.  
Although the majority of installations involves dial-up lines, the MT5600BR-V92 also connects to two-wire  
leased lines (sometimes referred to as dedicated, private, or 3002 lines) and four-wire lease lines.  
To connect the modem to leased lines, first determine the type of line termination provided by the phone  
company. Most phone companies provide a terminal block with a pair of screws. Some provide a  
conventional RJ11 type of connector. If the RJ11 connector is used, you can use the same cable that you  
use for dial-up connection. If the screw terminal type connector is used, you may need to order the  
#CA167 cable from Multi-Tech Systems.  
For a lease line connection, make two DIP-Switch setting changes on the modem's PC board. The first  
involves placing DIP-Switch #10 in the DOWN position (changes the modem from dial-up to leased line  
operation). The second DIP-Switch change requires that one of the two modems on the leased line circuit  
is set to "originate", and the other is set to "answer". To do this, change the setting of DIP-Switch #5.  
When you changed the DIP-Switch #10 setting, you also changed the function of DIP-Switch #5. Now the  
UP position selects answer mode while the DOWN position selects originate mode. Place DIP-Switch #5  
in the UP position on one of the two modems, and on the other modem, place Switch #5 DOWN. It  
doesn't matter which is which, just so you have local and remote modems in opposite modes.

2 Installation  
Installation  
Perform the following procedure to install modem cards into the CC1600 rack. The installation process  
involves:  
1.  
2.  
Verify that the DIP-Switch settings conform to your application (dial-up or lease line).  
Slide a modem card into one of sixteen available modem slots. Start by inserting a modem  
into the left-most channel (slot #1) of the rack. The toggle switch should be at the bottom of  
the card, with the component side of the card facing the right. The modem’s gold edge con-  
nector is offset so that the modem cannot be inserted incorrectly. Continue installing modem  
cards as necessary.  
3.  
Connect one end of an RS232C Cable to the appropriate modem slot (DB25/25-pin connec-  
tor-female) at the rear of rack. The other end of the RS232C cable is connected to the serial  
port of the computer.  
Note: Any cables connected to the computer must be shielded to reduce interference.  
4.  
5.  
Plug one end of the RJ11 cable provided with the modem into the rack's RJ11 connector  
(located on the back plane of the modem rack) and the other end into the phone-company-  
provided RJ11 or RJ11W modular phone jack.  
Verify the remote modem's current configuration settings with your MT5600BR-V92 in terms  
of data compression, error correction, transmission rate, etc. (Refer to Chapter 4 for AT com-  
mands).  
6.  
7.  
Make sure modem and computer/terminal serial port baud rates are adjusted.  
Proceed to Chapter 3 of this manual, or to your data communications software manual for  
modem configuration.

MT5600BR-V92 User Guide  
3 Configuration  
Chapter 3 - Configuration  
Configuring Your Software  
Communications software must be configured to work with your modem, your computer, and the remote  
system it is calling. Fortunately, most communications programs make the process easy by providing a  
default initialization string for your modem as well as defaults for most of the other required parameters.  
Configuring Software for Your Modem  
Because remote computers may have different connection requirements such as speed, number of bits,  
parity, log-on sequences, etc., communications software is typically configured by sessions, each session  
having a unique configuration for a given connection (e.g., to an FTP site or commercial online service).  
Most communications programs, however, have a separate modem configuration menu because modem  
configurations rarely change from session to session.  
The most important configuration is the modem initialization string. This is a sequence of commands the  
software uses to configure the modem when the communications software is loaded or when a session  
begins. Always begin the initialization string with the ATtention command AT, then follow it with the  
modem reset command, &F. Issuing a reset command before other commands ensures that you are  
starting with a known state.  
The rest of the commands in the initialization string depend on the capabilities of the modem and what  
you want it to do. Some older communications programs require you to create the initialization string by  
yourself. Most modern communications programs, however, provide you with a ready-made initialization  
string that is automatically selected when you choose your modem model from a list. It is a poor idea to  
use an initialization string intended for another modem, especially one from another manufacturer,  
because modem capabilities and command implementations vary from modem to modem. However, if  
your MT5600BR-V92 does not appear on a modem list, you may use the MultiModemII initialization  
string.  
PC Initialization Strings  
We recommend the following initialization string for a MT5600BR-V92 connected to a PC-compatible  
computer:  
AT &F X4 S0=0 ^M  
This string resets the MT5600BR-V92 to the factory default settings, selects extended result codes with  
NO DIAL TONE and BUSY, and turns off auto-answer. ^M must end every string sent to the modem from  
software. It is the ASCII code for the RETURN key on most keyboards, and the default code for the  
carriage return character in the MT5600BR-V92 and most communications programs. The carriage return  
character is defined in the MT5600BR-V92 in S-register S3; if you change it, you must also change the  
carriage return character code used in your communications software. If you send a command directly to  
the modem in terminal mode rather than indirectly through communications software, you must end the  
command string by pressing the RETURN key (<CR>) instead of adding ^M to the string.  
14  
 
MT5600BR-V92 User Guide  
3 Configuration  
Changing Default Parameters  
The default values for the other parameters in modem configuration menus rarely need changing. They  
typically include the dialing prefix (ATDT for touch-tone service and ATDP for rotary service), the dialing  
suffix (^M), the hang-up string (+++) ”Response” then (ATH0^M), and response messages (RING, NO  
CARRIER, BUSY, etc.). Communications software with a host mode might also include an auto-answer  
string (AT S0=1^M).  
Macintosh Initialization  
Macintosh computers cannot use RTS/CTS hardware flow control without a serial cable wired for  
hardware control.The Macintosh 128 and 512 models cannot use RTS/CTS flow control at all. For those  
Macintoshes turn off the default RTS/CTS hardware flow control, turn on XON/XOFF flow control, and  
ignore DTR:  
AT &F X4 &k4 &D0 ^M  
For hardware flow control, use the following initialization string:  
AT &F X4 &K3 &D0 ^M  
Add S0=0 to both strings to disable auto-answer if the MT5600BR-V92 is on a voice line.  
You can store the initialization string in nonvolatile memory. With your communications software open and  
connected to the modem’s COM port, type the initialization string in the terminal window, substituting a

Fax Commands  
Fax commands resemble AT commands, but are more complicated to use. Because of this, we  
recommend that you use a fax program to send and receive faxes rather than attempting to control the  
modem directly. Developers who need to know the fax commands for the MT5600BR-V92 can find Fax  
Class 1 and Fax Class 2 Reference Guides on the MT5600BR-V92 CD as well as the Multi-Tech Web

Appendix B - Firmware Upgrade  
Appendix B - Upgrading the Firmware  
Introduction  
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory.  
Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can  
be changed by either the manufacturer or the user as bugs are fixed or new features are added.  
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes  
by using the following procedures.  
Upgrade Overview  
The upgrade procedure consists of the following steps, which are described in greater detail in the  
following sections.  
1. Identify the model number and firmware version of your modem.  
2. Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has  
the current firmware, there is no need to update it.  
3. Download the upgrade file for your modem.  
4. Extract the firmware .HEX file and the appropriate flash upgrade program from the file you  
downloaded.  
5. Document and clear your stored parameters.  
6. Upgrade the modem’s firmware using the .HEX file and the flash upgrade program.  
7. Restore your parameters.  
Step 1 - Identify the Modem Firmware  
You must know the model number and firmware version of your Multi-Tech modem to know whether or not  
you should update it.  
1. Run your favorite terminal program. If you are using Windows, you can use HyperTerminal.  
2. In the program’s terminal window, type AT&F. Even if you cannot see the AT&F command on your  
screen, be sure to type it completely, and then press Enter. If the modem does not respond with OK,  
repeat the AT&F command.  
3. Now type ATI3, press Enter and record your results. The firmware version should appear first in the  
response, which should look similar to the following:  
ACF3_V1.702a_V90_P21_FSH  
23  
 
MT5600BR-V92User Guide  
Appendix B - Firmware Upgrade  
Step 2 - Identify the Current Firmware Version  
Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the  
current firmware, there is no need to update it.  
1. Using your favorite Web browser, go to http://www.multitech.com/support/MultiModemII/  
firmware.asp.  
2. Scroll down the table to your modem model number.  
3. Look at the firmware version number for your modem.  
4. If the firmware version number matches the firmware version number found in “Step 1: Identify the  
Modem Firmware,” your modem has the current firmware version, and does not need to be updated.  
5. If the firmware version number is greater than the firmware version number found in “Step 1: Identify  
the Modem Firmware,” your modem has an older firmware version. Continue with “Step 3: Download  
the Upgrade File.”  
Warning: The first digit of the new firmware must match the first digit of the old firmware, or the modem  
may not work properly; e.g., if your current firmware version is 4.16, replace it only with 4.xx firmware, not  
6.xx firmware.  
Step 3 - Download the Upgrade File  
1.  
2.  
3.  
If you are not already at the MultiModemII Firmware page of the Multi-Tech Web site, follow the  
procedure in “Step 2: Identify the Current Firmware.”  
Download the upgrade file for your modem by clicking its name, and save the file in a temporary  
folder on your hard disk.  
In the same section of the Web page, click the Flash Wizard utility for your operating system to  
download it, and save it in the same folder.  
Step 4 - Extract the Upgrade Files  
1.  
Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.  
2.  
Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file,  
which contains the upgrade data, and a Readme file.  
3.  
Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is at  
C:\Program Files\MultiTech Systems\Flash Wizard\.  
24  
 
MT5600BR-V92User Guide  
Appendix B - Firmware Upgrade  
Step 5 - ClearYour Stored Paramenters  
Before you flash your modem, you should record the parameters that are currently stored in it, so you  
can reprogram it after flashing. After you have recorded them, send the AT&F command to the the  
modem to clear the stored parameters.  
1.  
Run your favorite terminal program. If you are using Windows 98, Windows NT, Windows 2000,  
or XP you can use HyperTerminal.  
2.  
In the program’s terminal window, type AT&V and press Enter to list your modem’s current  
parameters.  
3.  
4.  
Record your parameters by saving the screens and sending them to your printer.  
Type AT&F and press Enter to clear your stored parameters and reset your modem to factory  
default.  
5.  
Close the terminal program.  
Step 6 - Upgrade the Modem’s Firmware  
Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive  
file. Note the file name for the boot code (e.g., F35ALOAD.S37) and the file name for the new firmware  
(e.g., BKQG300G.HEX).  
WARNING: Never install an older version of firmware over a newer version. Doing this WILL DESTROY  
THE FLASH PROM! If the flash PROM is destroyed, the modem must be sent in for repair.  
1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the Start menu. The  
Identifying Devices dialog box is displayed as Flash Wizard locates and identifies the devices  
connected to your system.  
Note: If the message ERROR: No valid devices detected is displayed, verify that the modem is  
turned on and that all cables are correctly and securely attached.  
2. Click the modem to be upgraded, and then click Next to proceed.  
3. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex File  
list, and then click Next to continue.  
Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.  
4. The Progress dialog box appears, showing a status bar that indicates the progress of the upgrade.  
Caution: Any disruption of the program during this stage of the upgrade can cause your modem to  
become inoperable. Wait for the Next button to become active before proceeding.  
5. When the flash upgrade is complete, the message Programming Complete appears. Click Next to  
continue.  
6. The Results dialog box appears next. Click Finish to exit Flash Wizard.  
Step 7 - RestoreYour Parameters  
Your modem has been updated. You can now open your terminal program to reprogram your modem  
parameters or to confirm the update by typing ATI3 in the terminal window and pressing Enter.

Appendix D - WEEE Statement  
Appendix D – Waste Electrical and  
Electronic Equipment (WEEE)  
The WEEE directive places an obligation on manufacturers, distributors and retailers to take-back  
electronics products at the end of their useful life. A sister Directive, ROHS (Restriction of Hazardous  
Substances), complements the WEEE Directive by banning the presence of specific hazardous  
substances in the products at the design phase.  
The WEEE Directive covers all Multi-Tech products being sold into the EU as of August 13, 2005.  
Manufacturers, distributors and retailers are obliged to finance the costs of recovery from municipal  
collection points, reuse, and recycling of specified percentages per the WEEE requirements.  
Instructions for Disposal of WEEE by Users in the European Union  
The symbol shown below is on the product or on its packaging which indicates that this product must not  
be disposed of with other waste. Instead, it is the user’s responsibility to dispose of the user’s waste  
equipment by handing it over to a designated collection point for the recycling of waste electrical and  
electronic equipment.The separate collection and recycling of waste equipment at the time of disposal  
will help to conserve natural resources and ensure that it is recycled in a manner that protects human  
health and the environment. For more information about where you can drop off your waste equipment for  
recycling, please contact your local city office, your household waste disposal service or the seller from  
whom you purchased the product.
