• RedBoot Command Overview
Optionally, you can install PortVision DX on a Windows system on the network
and perform all of these tasks. PortVision DX provides a Telnet/SSH session,
which is discussed in Accessing RedBoot Commands in Telnet/SSH Sessions
(PortVision DX) on Page 37.
To access RedBoot, you can use one of the following methods:
• A serial connection between Port 1 on the DeviceMaster UP and a COM port
on a PC (Page 42). If you plan on using the serial method, you will need a null
modem cable, a terminal program installed and configured on the PC, and a
Bootloader Timeout value in excess of 15 seconds. If the Bootloader Timeout
value has been reduced to 1 second, this procedure will NOT be possible.
Note: Use the serial connection method, if the DeviceMaster UP is not on the
same Ethernet network segment as the PC.
If you do not know the IP address of the DeviceMaster UP you must use a
serial connection to communicate with the DeviceMaster UP.
• A telnet connection (Page 43), if the DeviceMaster UP is locally accessible by
Ethernet. A telnet connection requires that you know the IP address. In
addition, the IP address must also be valid for the network to which it is
attached.
For example: The network segment must be 192.168.250.x to telnet to the
DeviceMaster UP default IP address if you have not changed the IP address to
operate on your network.
