M5000 Portable Data Terminal American Microsystems, Ltd.

Non-Portable Mode

Once the Non-port mode is selected from the Main Menu, the interface mode is automatically

determined based on your cable connection. It may be necessary to reselect non-port mode on the

Main Menu if cable changes are made during non-port mode. Two ways in which the M5000 PDT

relays bar code data to the host computer are keyboard wedge and RS232 serial.

Keyboard Wedge transmits bar code data to the host computer via a hardware device called the

M5100 Keyboard Wedge. This device is connected in-line to the host computer’s keyboard and sends

data to the host computer as if it were typed from the host keyboard.

RS-232 Serial transmits bar code data to the host computer’s serial port. This mode uses the protocol

and serial parameters from the Communications Setup option. (Refer to Comm. Setup page 21.)

Upgrade Flash

—

Previously, if you wanted to update portable bar code reader

firmware, you would physically open the scanner and replace the EPROM and in some cases is

costly, time consuming and complicated. Today you can use a much easier method. The flash

memory can be easily updated using our communications interface cable, IBM compatible computer

and a software file.

You can download amended firmware only if American Microsystems Technical Support has

instructed you to upgrade the firmware on your M5000 PDT.

Warning! When this option is selected the M5000 PDT warns you that you

will lose all program files and data files if you proceed. You may wish to

validate proper xmodem communication through your serial port.

1. Connect the communications interface cable (RS-232) into an available RS-232 port on your

computer.

2. Connect the opposite end of the communications interface cable to the RJ45 10-pin connector

the bottom of the M5000 PDT.

3. On your M5000 PDT from the Main Menu select Upgrade Flash (U). You will be prompted by

the confirmation message, All Data & Programs Will Be Lost! Are You Sure? Choose Y or toggle

this selection to (yes). The M5000 PDT is now waiting for connection.

4. To access the M5000 Programmer software from WIN95 taskbar, click Start, select Programs,

select M5000 Utilities and select M5000 Programmer.

Under the Communications menu, select Upgrade Flash. The communications submenu is then

brought up on the screen and file selection dialog box will prompt you to select a UPG file

(image.upg).

Press ok to select UPG file.

The Communications dialog will again appear press Send to upload flash upgrade.

Once the file has been transmitted, the flash upgrade is complete. The M5000 PDT automatically

returns you to the Main Menu. The options will be reset to factory defaults.
