Q38: I updated Observer software and recorder firmware to V 2.22 or above, DDE is not working
properly with application of the third party.
A38: From Observer 2.22 on, DDE format has been changed with the Tag name. For example, instead of
Analog input1 AIn, now it becomes TAGn, which n stands for the number of channel.
Q39: I want to exchange available data from Real- time Viewer with third-party applications in
other computers in the same local area network, is there any solution?
A39: Real time viewer supports DDE application. It is possible to configure NetDDE and then exchange
data from Real-time Viewer to other computers connected in the network via DDE. Please refer
section 4.4.1.4 NetDDE for configuration details.
Q40: A customer complains that the clock of recorder is faster in 2 minutes each month. What is
solution?
A40: Because of the nature of crystal, the real time clock of recorder might get a big error if the ambient
temperature of recorder is high. The user should use the synchronization feature of PC software to
synchronize the time of recorder with the time of PC. In configuration of PC software, click
“ Clock ” icon, and click the “ Synchronize ” button, then it is done.
