Remote Time Setting On The NDACS 6000 Instruments

TImseSetter.jar Utlity Software

The NDACS 6000 contains it’s own real-time clock that can be set automatically to the time on the data server computer by using a simple utility program named TImeSetter.jar. No matter what type of data connection is made to the NDACS the same command is used to set the instruments time.

java - jar TImeSetter.jar ip-address Offset

where

IP address - is the address of the instrument
Offset - Hours offset from current time on the data
server PC. The offset is useful when the
instruments are located in different time
zones to the data server computer.

Example 1.

Setting NDACS systems time across a local area network
for all instruments shown in Fig 1 with no offset from the data server time.

Use a DOS batch file containing the following instructions

java -jar TImeSetter.jar 192.168.0.1 0
java -jar TImeSetter.jar 192.168.0.4 0
java -jar TImeSetter.jar 192.168.0.7 0
java -jar TImeSetter.jar 192.168.0.11 0

Example 2.

Setting the instrument time for systems on a dial-up distributed network as shown in Fig 2. For this example the instruments are connected to a modem located on telephone number 0845 1264001. Use a +2 hours offset to the local data server time.

rasdial.exe is the standard Windows Operating system utility to dial a modem. Any other method for dialling up a remote modem can be used.

Use a DOS batch file containing the following instructions

rem optional modem dial software
rasdial 0845 1264001
java -jar TImeSetter.jar 23.0.0.36 2
java -jar TImeSetter.jar 23.0.0.37 2
