Description of Arguments
Command or Query.
Sets External Frequency Reference in the form x, where:
0=Internal 10MHz (default)
1=External 1 MHz
2=External 2 MHz
3=External 5 MHz
4=External 10 MHz
5=Internal 10MHz plus output - this means that the Reference is available on
the "Ext Ref" rear connector (small rear-panel LED indicates when ON).
Example: EFR=1 (External 1MHz)
Command or Query.
Enable/disable flow control (applies to all ports) in the form x, where:
0=Disable GBEI Flow Control
1=Enable GBEI Flow Control
Command only.
Resets internal pointer to allow RNE? queries to start at the beginning of the stored
events log.
Query only.
Active software image in the form x, where:
0=Bulk Image #1 currently active
1=Bulk Image #2 currently active
Command or Query.
Used to set the IP Address and network prefix for the 10/100 Base T Ethernet

follows:
aaa: 0-223
bbb: 0-255
ccc: 0-255
ddd: 0-255
yy is the network prefix (range: 8 to 31)
Example: IPA=010.006.030.001.24
Command or Query.
