Baud Rate

This is the asynchronous rate that the maintenance port will run. The possible values are 300, 1200, 2400, 4800, 9600 (def), 19200, 38400, and 57600.

Data Bits

This is the asynchronous bit rate that the maintenance port will run. The possible values are 7 or 8 (def) bits.

Parity

This is the asynchronous parity that the maintenance port will run. The possible values are NONE (def), ODD, or EVEN.

Stop Bits

This is the stop bit used for the maintenance port. The possible values are 1 (def), 1.5 or 2.

> Network Time

The TA 544 unit time can be entered manually from the SYSTEM INFO menu, or the unit can receive time from an NTP/ SNTP server. The NETWORK TIME menu includes all parameters relating to how the unit communicates with the time server.

Server Type

The server type defines which port the TA 544 will listen on to receive timing information from the time server.

NT Time

The TA 544 will receive time from an NT server running SNTP software on its TIME port.

SNTP

The TA 544 will receive time directly from an SNTP server.

Active

This network timing feature can be turned on and off. It determines whether the unit will request and receive time from a time server.

Time Zone

There are several time zones available for the time to be displayed in. All time zones are based off of Green- wich Mean Time (GMT).

Adjust for Daylight Saving

Since some areas of the world use Daylight Savings Time, the TA 544 is designed to adjust the time on the first Sunday in April and the last Sunday in October accordingly if this option is turned on.

Host Address

This is the IP address of the time server that the TA 544 will request and receive time from.

Refresh

This is the interval of time between each request the TA 544 sends out to the time server. A smaller refresh time guarantees that the unit receives the correct time from the server and corrects possible errors more quickly, but it is more taxing on the machine. A range of refresh times is available for the user to decide which is best for their unit.
