MT5600BA MultiTech Modem Information

Step 1: Verify that the MT5600BA was designed specifically for IBM. On the bottom of the modem, there is a sticker to identify the modem.

Caution: If this modem is not from IBM, flashing any firmware will destroy the modem.

Step 2: To verify the firmware level and to update the firmware level, the modem must be attached to a PC. However, before attaching the modem to the PC, it must be set for asynchronous mode so that the modem can communicate with the PC. Refer to the modem diagram above. Set the modem to the factory defaults to set it in asynchronous mode. To return the modem to the factory settings, do the following:

1.	With the modem in idle status, press the down arrow until you see BASIC OPTIONS.
2.	Press the right arrow until you see ONLINE OPTIONS.
3.	Press the down arrow until you see RESET FACTORY DEFAULTS.
4.	Press the right arrow, and you will see RESET TO FACTORY NOW?
5.	Press the Enter key, and you will see FACTORY DEFAULTS RESTORED.

Step 3: Attach the modem to the PC.

Step 4: After the modem is attached and powered on, insert the setup CD that came with the modem. If autorun is enabled on the PC, a screen similar to the following is shown:



Step 5: Click on Initial Setup & Country Selection, and choose Run Global Wizard From CD. Click Next, and the software attempts to locate the modem. If successful, a screen similar to the following is shown. Record the port. Click Next to continue, and select the country for the modem.



Step 6: To determine the firmware, on a Microsoft Windows operating system, open Hyperterminal. Click on Start > Run, and type hypertrm.exe. If this program is not found, refer to the operating system documentation. The next screens will take you through getting a terminal session to the modem.

Type a name for this description. Click OK.



Select which port the modem is connected to. Refer to Step 5. Leave everything else as the default. Click OK.



Choose 115200 for the speed. Leave everything else as the default. Click OK.



Step 7: When Steps 1 through 6 are completed, you are shown a terminal screen. Type ATI3 (AT, letter I), and press the Enter key. The firmware version is shown. In this example, V1.702M is the firmware level. If the modem being tested is not at this minimum level, it must be updated.

Caution: This is for the MT5600BA modem manufactured for IBM only. Updating the firmware on other MT5600BA modems damages the modem. Contact your IBM Hardware support for this modem to obtain the latest firmware version. After the modem is flashed, downgrading is not possible. Do not attempt to reflash the same firmware because this causes damage. Ensure all background programs are closed (anti-virus, anti-spyware, and so on) and the power save mode is disabled. Do not download firmware from the manufacturer's Web site. Consult with IBM hardware support for firmware information.

Attached Firmware



Step 1: Follow Steps 2 and Step 3 in the above section to attach the modem to a PC.

Step 2: Go to www.multitech.com/SUPPORT/Families/MultiModemII/software.asp to download the Flash Wizard application to update the firmware. The included CD for the modem contains a Flash Wizard program; however, it is best to download the latest version.

Note: This modem is from the MultiModem II family. Ensure the Flash Wizard is compatible with the MT5600BA modem.

Step 3: Install the Flash Wizard program. Record the directory that this application is installed to.

Step 4: Download the firmware for this modem, and unzip it to the directory that the Flash Wizard is installed to. To find the directory, click on Start > Programs > find the Flash Wizard icon. If the icon is found, right-click on that icon, and go to Properties. The directory is listed in the Short Cut tab. In this example, the directory is C:\Program Files\Multi-Tech Systems\Flash Wizard\. This is where to unzip the firmware.



Step 5: Once the firmware is unzipped to the directory, run the Flash Wizard by Start > Programs > Flash Wizard. Follow through with the instructions until it is updated.

Highlight the modem.



Ensure the firmware level is selected and the port is highlighted.



Note: This process can take a while.

To configure for SDLC, do the following:

Step 1: Refer to Step 2 in the Verifying Firmware Level section to return the modem to factory defaults.

Step 2: With the modem showing IDLE, press the down arrow until BASIC OPTIONS is shown.

Step 3: Press the right arrow key until you see ONLINE OPTIONS.

Step 4: Press the down arrow key until you see SYN/ASYNC OPTIONS.

Step 5: Press the right arrow key until you see V.25bis HDLC NRZ. Press the Enter key. You will see OPTION SET. Power the modem off and on again.

Step 6: To verify the configuration, follow Steps 1 through 3 to get to SYN/ASYNC OPTIONS. Press the right arrow one time. You are shown CURRENT SETTING=SYNC H.

Step 7: Set the modem baud rate :

1.	Follow Steps 1 and 2 until you see ONLINE OPTIONS.
2.	Press the down arrow key until you see CONNECTION RATE OPTIONS.
3.	Press the right arrow key one time. You will see SERIAL BAUD RATE.
4.	Press the down arrow key until you see MODEM SPEED.
5.	Press the right arrow key until you see a speed of 33,600 with V.34 option. Press the Enter key, and it should be changed.
6.	Press the left arrow key until the modem shows IDLE in the front panel.
7.	Repeat Steps 1 and 2 until you see CONNECTION RATE OPTIONS again.
8.	Press the right arrow key one time. You will see SERIAL BAUD RATE.
9.	Press the right arrow key once again. You will see the current settings. If the setting is not set at 115200, then press the right arrow key until you find the correct speed. Press ENTER. Press the left arrow key until the modem shows IDLE in the front panel.

Step 8: Change the Carrier Detect option :

1.	With the modem showing IDLE, press the down arrow until ADVANCED OPTIONS is shown.
2.	Press the right arrow key until DTR OPTIONS is shown.
3.	Press the down arrow key until CARRIER DETECT OPTIONS is shown.
4.	Press the right arrow key until CD NORMAL shows.
5.	Press the Enter key.
6.	It might be necessary to power cycle the modem to turn off the CD light.

Step 9: At this point, power off and power on the modem.

MT5600BA modem profiles have been added to the system with the following PTFs:

V5R3 PTF SI22314
V5R4 PTF SI22428

Both of these modem profiles assume that the modem is set to its default configuration, which is for asynchronous operation using AT commands.
