Two commands allow you to check the communication links from a computer or
network to the TimeProvider: PING and RTRV-HDR.
Ping
Use the PING command to check an Ethernet connection to the TimeProvider.
PING:[<tid>]::[<ctag>]::<ipaddr>;
This command has a default access level of USER.
Sample Command
PING:::TS1000::192.168.12.10;
Normal Response

;
Retrieve Header
Use the RTRV-HDR command to display the response header, which includes the
system identification <sid>, date, and time. You can also use this command to verify
that the communication link to the TimeProvider is working properly.
This command has a default access level of NONE.
