BTIMER:
Set the broadcast timer for 32/64/128/256/512/1024
seconds interval
Level 4:
Same as level 3 operation.
Example:
If the SSU2000 has a GPS module installed and the module is locked
with satellites, it then has UTC time. The SSU-2000 is automatically an NTP
SERVER at Stratum Level 1. When the system (with GPS module installed and
UTC time) is a SERVER, it cannot operate as a client.
If the system is an NTP server, you can set your system for broadcast mode by the
commands:
NTP ADD BROADCAST XXX.XXX.XXX.255
and
NTP BTIMER NNNN
Note
: The broadcast mode only works with class C networks with no gateway.
Example:
If your unit IP address is 172.16.18.20, then the broadcast mask may be
172.16.18.255.
Your system can be configured as a client (if you don’t have a GPS module
installed) by the command:
NTP ADD CLIENT XXX.XXX.XXX.XXX
This is the most common mode to get timing packets.
If your system is not a server, it can also be configured as a broadcast client to
receive timing packets from a broadcast server by the command:
NTP ADD BCLIENT XXX.XXX.XXX.XXX
For more information on these and other NTP commands, refer to
, on page 266, and
SNMP Protocol
This section describes the two versions of SNMP that the SSU-2000 supports. The
Communications module software determines the version of SNMP used by the
SSU-2000. See
for the part number for the various software loads that are
available.
SNPMP v2 Details
SNMP is based on a client-server query-response mode that requires an Ethernet
connection. A manager application (software installed on a computer) is the client
generating the queries, and an agent (software on the SSU-2000) is the server
generating responses.
