4.4.1F100 BASET – 100 BASE-T/10 BASE-T Control

Use the BASET command to query the current Base-T setting. If you set the unit to 10Base-T, it operates only at that speed. If you set the unit to 100Base-T, it negotiates between 10/100Base-T. This does not necessarily mean the unit will connect at 100Base-T, but will connect at the fastest possible speed. Any change to the current Base-T setting causes the unit to reset.

To query the maximum Base-T speed, send the following command:

F100<SP>BASET<Enter>

where

F	=	ASCII character F
100	=	unit function number
<SP>	=	space
BASET	=	specify Base-T command
<Enter>	=	input line terminator

An example of the response is:

F100 BASET 100T

To set the maximum connection speed to 100Base-T, send the following command:

F100<SP>BASET<SP>100<Enter>

where:
100	=	set maximum Base-T speed to 100

To set the maximum connection speed to 10Base-T, send the following command:

F100<SP>BASET<SP>10<Enter>

where

10 = set maximum Base-T speed to 10

In both these cases, the unit responds:

Are you sure? (y/N)

As a safety feature, after sending this command, you have 10 seconds to respond affirmatively (enter the letter “y”) to the confirmation prompt, after which the unit executes the command and resets. Within that 10 second time period, any other response, including no response, results in the unit canceling the command.

For details about an initial 100Base-T setting, see “NET Port Network Parameters: First Time Configuration” on page 2-28.
