I thought of putting this article as you might also come across similar issues, also trust me on this, up to the date, until I uploaded this blog post, myself or any one of my team mates couldn’t find a single article about solving the data download from AC121 through internet. Even the AC 121 manual couldn’t do much for us.
AC 121 was fixed at a client site in location X and the Cyber Concepts Time Attendance software was installed at the HQ of the same client. There was only a network cable connected to the Realand AC 121 and there was no computer on site which could connect to the AC 121 Biometric device to download attendance data.
Since i have configured few types of biometric scanner devices with our Time and Attendance solution, I thought AC 121 would be another walk in the park.
Sadly it was not. Even though I tried all possible configurations, the pc on the HQ was not even able to connect to the biometric device.
Since the usual setup did not work I had to go to the drawing board.
Going back to the drawing board
Going through what you have already done, up to now always lead you to a solution at least in this case a lead to a solution.
Here is my check list
IP : 192.168.1.85
Gateway : 192.168.1.254
Subnet : 255.255.255.0
DNS : 0.0.0.0
Also keep in mind that DHCP should be always set to NO, as if this is active the device will not let you enter any network settings.
I went through the RT PUSH menu; it had RS234, UDP and NO as options. Since we had nothing to do with RS234 and it was already set in as NO, I went with UDP, without changing anything and ONLY doing what I mentioned above, I tried to connect to the machine from the HQ, still nothing.
It hit me at this point since the RT PUSH was set to UDP; it was a no brainer that the port forwarding record should be changed to UDP protocol as well.
What a relief!!, it connected beautifully,
A special thank you goes out to Tharindu and Jayan for being aside me and helping me out,
