which is discussed in

(PortVision DX) on Page 135.
Accessing RedBoot Overview
To access RedBoot, you can use one of the following methods:
• A serial connection between Port 1 on the DeviceMaster and a COM port on a
PC (Page 140). 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 is not on the same
Ethernet network segment as the PC.
If you do not know the IP address of the DeviceMaster you must use a serial
connection to communicate with the DeviceMaster.
• A telnet connection (Page 141), if the DeviceMaster 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 default IP address if you have not changed the IP address to
operate on your network.
