The intent of this Technical Note is to provide an abbreviated set of commands and procedures to initially check out the functionality of a Lily Borehole Tiltmeter, and configure it for storing data to the non-volatile memory. Refer to the LILY Self-Leveling Borehole Tiltmeter Manual for complete detailed information.
Initial Check-Out Procedures
Before installing your Lily, verify that it is functioning properly by following the steps below. Refer to the firmware command summary in Section 8.3 of the manual. The following instructions assume that the operator is using HyperTerminal (Windows 95 and later) or any other suitable program to communicate with the Tiltmeter:
- On your computer open HyperTerminal. Select the proper COM port and baud rate. The default baud rate for your Tiltmeter is 19200 and the default output is on the RS-232 port. NOTE: double-check your RS-232 or RS-485 converter’s DB9 pinout against the pinout for the Lily’s DB9s. See tables A1-A3 in the manual.
- Plug in the power supply, then attach the barrel connector to the Lily cable.
- Back in HyperTerminal, you should notice the power-up screen.
- Type the command *9900XYC2. If properly attached, the Tiltmeter will now start outputting data through the serial port at a rate of 1 reading per second, and the data will be displayed in HyperTerminal. NOTE: The Tiltmeter firmware commands are case sensitive.
- Tilt the unit in the +X and then the +Y direction (Figure 6 in manual). Next, tilt it in the –X and –Y directions. Verify that the tilt values move through the full measurement range (Section 3) and that the sign (polarity) of the output changes on opposite sides of null.
- While holding the unit more or less vertical, rotate the unit and observe that the compass reading is changing.
- Type the command *9900XYC-OFF to stop the output.
- Your LILY Tiltmeter is now ready for installation.
