Transferring readings from TTR to PC (Get from TTR window)
To transfer data to a PC, log to the disk drive and/or directory that contains the
COMLink program and select it. Connect the TTR's RS232 port to the PC
through a cable (Megger p/n 33147-18) supplied.
If the USB port is used, plug a USB serial adapter, USA-19QW or equivalent, into
the USB port of the PC. Connect the TTR's RS232 port to the adapter. Install the
software drivers for USB serial adapter (supplied with the adapter).
The COMLink program starts with the opening window. In the Select Device
window, select Single Phase TTR. The Transfer Readings to PC screen appears.
Select Maintenance tab, then, select the Setup Serial Port tab. The COMLink
Setup serial port window will appear. This window allows you set up the serial
port for communication to the remote device.

remote device. The following parameters should be selected:
Select the com. port to be used
Baud Rate: 38.4 kBaud
Parity: N(none)
Stop bits: 1
Data bits: 8
NOTE: The serial port settings are already appropriately set for the selected
device. However, the COM port will need to be selected.
Select Save Settings to set the serial port parameters to those you selected and
to initialize the serial port. Select OK button.
Select Restore Settings to leave the serial port parameters unchanged.
