DeviceMaster Installation and Configuration Guide: 2000506 Rev. B RedBoot Procedures - 75
RedBoot Procedures
Use this section as a reference if you want to perform tasks in Redboot. Typically, most of
these procedures can be performed using PortVision Plus.
Overview
You can use a serial connection between Port 1 on the DeviceMaster and a COM port on a
PC. If you plan on using the serial method, you will need a null modem cable and a
terminal program installed and configured on the PC.
Note: Use the serial connection method, if the DeviceMaster is not on the same Ethernet
network segment as the PC.
You can use a telnet connection, if the DeviceMaster is locally accessible by Ethernet.
If necessary, see Establishing a Serial Connection
on Page 75 or Establishing a Telnet
Connection on Page 76 to disable the Bootloader before performing any of these
procedures.
Establishing a Serial
Connection
Use the following procedure to set up serial connection with a terminal server program
(for example, Test Terminal (WCom2), HyperTerminal or Minicom) and the
DeviceMaster. Test Terminal (WCom2) is available in PortVision Plus or you can also
install the Comtrol Utility package.
1. Connect a null-modem cable from an available COM port on your PC to Port 1 on the
DeviceMaster.
Note: See DB9 Serial Cables and Loopback Plugs
on Page 59 or RJ45 Serial Cables and
Loopback Plugs on Page 61 to build a null-modem cable.
2. Configure a terminal server program (such as, HyperTerminal or Minicom) to the
following values:
• Bits per second = 57600
• Data bits = 8
• Parity = None
• Stop bits = 1
• Flow control = None
3. Reset the DeviceMaster.
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.
Note: If you do not disable the loading feature of the
Bootloader 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.
6. Verify that the system responds with a Loading disabled message.
