WELL WATCH 1100 USER MANUAL - Eno Scientific

To automatically log data on a schedule, press the SET button repeatedly until the
logging screen appears. Then press the UP or DOWN button until the second display
line reads ENABLED. Then press the SET button again to show the log period screen.
Press the UP or DOWN button to set the log interval in minutes. If the log period is set
to 2 minutes, the Well Sounder will initiate a log sequence every two minutes. The time
between logged data may vary by a few seconds depending on how long it takes to get
a stable reading. If the log period is set to zero minutes, then every reading is logged.
Log margin is a second logging option available to reduce the the amount of data
collected on wells where the water level may not change for long periods. To turn on
this feature, press the SET button repeatedly until the logging screen appears. Then
press the UP or DOWN button until the second display line reads “ON CHANGE”. Then
press the SET button again to show the log period screen. Press the UP or DOWN
button to set the log interval in minutes. Then press the SET button again to show the
log margin screen. Press the UP or DOWN button to set the log margin in feet (M). If
the log period is set to 2 minutes and the log margin is set to 1 ft, then every 2 minutes
the current reading is compared to the last logged reading. If the difference is less than
1 ft then the current log sequence is cancelled.
RS232 COMMUNICATIONS
The Well Sounder offers a standard serial communications port for connection to a
computer or remote device such as a SCADA system or remote readout. A 9 pin D
connector on the side of the unit allows the unit to connect to a computer or other
RS232 device using a standard straight through serial cable. A simple serial to USB
adapter is available from Eno Scientific or most computer stores to use with laptops
without serial ports. The default serial configuration on the Well Sounder is 19200
baud, 8 data bits, 1 stop bit, no parity, and no flow control. The baud rate can be
changed from the set screen on the keypad.
The serial port is bi-directional and allows communication from the Well Sounder to the
remote device and back. This allows the Well Sounder to be programmed and
operated from a remote location. The Well Sounder offers a complete command set
over the serial link to allow configuring the Well Sounder settings as well as requesting
a down load of the log data. A standard terminal emulator program such as
HyperTerminal (included with windows) or Tera Term Pro 4.69 (available for free
download) can be used from a computer to operate the Well Sounder remotely (see the
section on remote operation).
