How to Upgrade a TimeCalculator from Serial/USB to TCP/IP Network

Upgrading a TimeCalculator from a serial or USB connection to TCP/IP networking allows the clock to communicate directly over your local network for faster, more reliable data transfer. This process involves installing a network interface board and configuring the hardware connection properly. The following procedure reflects standard upgrade practices used by technicians working with systems from Icon Time Systems.

Hardware Preparation and Disassembly

Before installing the network module, the unit must be safely opened and the internal board prepared. Proper handling prevents damage to the display board and internal connectors. Unplug the machine and lay it face down Remove the four rear housing screws and take off the back cover Remove the four PC board mounting screws using a small Phillips driver Carefully tilt the board outward Locate the 1-inch removable chip on the board Remove the chip using a small flat-blade screwdriver Reposition the board and secure mounting screws

Install the TCP/IP Interface Board

The network upgrade uses a Tibbo interface module that mounts above the display board and connects directly to the existing circuitry. Mount the Tibbo board behind (above) the display board Use the provided 1.25-inch screws and spacers between boards Secure the board using the two available mounting points Connect the cable to both the top and bottom connectors Ensure wire alignment matches top-to-top terminal orientation Confirm all connections are firmly seated before closing This network module is manufactured by Tibbo Technology and must be wired in a direct one-to-one configuration to function properly.

Reassembly and Network Activation

After installation, the device must be reassembled and connected to the network before software communication can occur. Replace the rear housing cover Plug the custom network cable into your LAN Power the unit back on Launch the time clock software Install updated drivers if required (commonly for Windows 7 or 8 systems)

Conclusion / Operational Takeaway

Upgrading a TimeCalculator to TCP/IP replaces limited direct connections with full network communication, improving reliability and accessibility. When the interface board is mounted securely, wiring is matched correctly, and drivers are installed, the clock integrates seamlessly into your network environment. Careful hardware handling and proper cable alignment are the critical factors that determine upgrade success.
