Versions Affected:

Problem affects versions: Firmware R9.4a
Problem is fixed in version: R9.4b

Resolved In Version:

Problem is fixed in version: R9.4b


Symptoms:

When using the PAC Control command Synchronize Clock SNTP, if the specified time server address can't be reached, the chart or host task may become unresponsive. Anything that prevents a connection to the specified time server, including a bad address, an unplugged cable, or an unresponsive server, may cause this issue.

A power cycle is required to recover.

Workaround:

Attempt to open a COM handle to the time server address. If the connection is opened successfully, close it and do the time sync; if the open fails, do not attempt the time sync.

Resolution:

Opto 22 has resolved this issue.
