Managing Bootloader
Bootloader refers to the operating system that runs on the DeviceMaster LT
hardware during the power on phase, which then loads SocketServer.
Note: T
ypically, you should not update the Bootloader unless advised to do so by
Comtrol Technical Support.
There are several methods and tools that you can use to
check the Bootloader
version or update the Bootloader.
• Po
rtVision DX is the easiest way to check the Bootloader version and upload
the latest version.
• Optionally, RedBoot can be used to check the Bootloader version and update
the
Bootloader. See
RedBoot Procedures on Page 99 for procedures.
Checking the
Bootl
oader Version
The following procedure uses PortVision DX to check the Bootloader version.
Optionally, you can use RedBoot, see
Determining the Bootloader Version on Page
103.
1. If you have not done so, install PortVision DX (
Installing PortVision DX on
Page 15) and Sca
n the network.
2. Right-click the DeviceMaster LT in the Device List pa
ne and click Advanced >
Reboot.
3. Click Ye
s to the Confirm Reboot query.
4. Right-click the DeviceMaster LT in the Device List pa

Uploading
Bootl
oader
Use the following procedure to upload Bootloader to the DeviceMaster LT.
Typically, you should not update the Bootloader unless advised to do so by Comtrol
Technical Support or a notice has been posted to the firmware download page on
the ftp site.
Note: T
echnical Support does not recommend updating Bootloader across a WAN.
For best results, connect the DeviceMaster LT directly to a PC or laptop to
upload Bootloader.
Make sure that power is not interrupted while uploading Bootloader.
P
ower interruption while uploading Bootloader will require that the
DeviceMaster LT must be sent into Comtrol so that it can be reflashed.
If you are not successful uploading SocketServer into the DeviceMaster
L
T, do not upload Bootloader.
1. If you have not done so, install PortVision DX (
Installing PortVision DX on
Page 15) and Sca
n the network.
2. If necessary, check the Bootloader version (Checking the Bootloader Version
)
and download the latest version.
