RedBoot Procedures

Establishing a Serial Connection

Use the following procedure to set up a serial connection with a terminal server
program. You can use HyperTerminal (Windows) or optionally, Test Terminal
(WCom2), which can be accessed from PortVision DX using Tools > Applications >
Test Terminal (WCom2
).

1.

Connect a null-modem cable from an available COM port on your PC to Port 1
on the DeviceMaster UP.

Note: See

Connecting Serial Devices

on Page 25, if you need to build a null-

modem cable.

2.

Configure the terminal server program to the following values:

Bits per second = 57600

Data bits = 8

Parity = None

Stop bits = 1

Flow control = None

Note: If you do not disable Bootloader from loading (Steps 3 through 5) within

the time-out period (default is fifteen seconds), an application will be
loaded from flash and started. If this happens, repeat Steps 3 through 5.
The #!DM command is the only case-sensitive command and must be in
uppercase.

3.

Reset the DeviceMaster UP.

Note: Depending on the model, disconnect and reconnect the power cable

(external power supply and no power switch) or turn the power switch
on and then off (internal power supply).

4.

Immediately type #!DM and press Enter in the terminal program.

5.

At the RedBoot> prompt, type dis, and press Enter.

6.

Verify that loading has been disabled.

7.

You can use the appropriate procedure listed on Page 41 or use the
