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 94.
Accessing RedBoot Overview
To access RedBoot, you can use one of the following methods:
•A serial connection between P
ort 1 on the DeviceMaster LT and a COM port on
a PC (Page 100). 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
Bootloa
der 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 LT is not on the
same Ethernet network segment as the PC.
If you do not know the IP address of the
DeviceMaster LT you must use a
serial connection to communicate with the DeviceMaster LT.
•A tel
net connection (Page 101), if the DeviceMaster LT is locally accessible by
Ethernet. A te
lnet 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 LT default IP address if you have not changed the IP address to
operate on your network.
