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
N
ONE
(def),
O
DD
,
or

>NetworkTime
The TA 544 unit time can be entered manually from the S
YSTEM
I
NFO
menu, or the unit can receive time from an NTP/
SNTP server. The N
ETWORK
T
IME
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, theTA 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 theTA 544 will request and receive time from.
Refresh
This is the interval of time between each request theTA 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.
