After replacing the battery, and checking the voltage on the small lipo battery soldered to the circuit board I still cannot get my desktop to communicate with the Siemens. I am using an old Dell optiplex with a 25 pin serial port and a SDNC program in a surfcam suite to transfer the data. I have followed the instruction, but cannot get Tea1, Tea2, and SEA to show up and confirm the transfer. Anyone have any ideas? The Hardinge service rep lives in colorado and would be pretty pricing to fly him out and install it.
