Eno Scientific LLC WS310 Manuel D’Utilisation
The Well Watch 310 display unit contains an expanded memory which provides
enough memory to record one data point per minute for over 50 years. This memory
supports a windows compatible file system which can be accessed using the USB port.
When the display unit is connected to a computer with the included USB cable, the
computer will identify the unit as a mass storage device and show the available log files
in an explorer window which can be copied directly to a directory on the computer and
deleted from the memory.

The log data files are simple ascii text files which can be opened with any common
program such as Notepad, MS Word or Excel. The data files created are named
WLOGxxx.TXT where xxx is the remote device address in the form 001 etc. Each data
point stored is appended to the file corresponding to the currently installed remote
device address. If a file does not exist for that address, it is created. Once the data is
copied to the computer, the file can be deleted from the display unit. A new file will be
created if the same address is used.

RS232 COMMUNICATIONS
The Well Watch 310 display unit offers a standard serial communications port for
connection to a computer or remote device such as a SCADA system or remote
readout. Screw terminals are provided for connection to the RS232 port. To connect to
a standard device such as a PC with a standard 9 pin D connector, only 3 wires are
necessary. The RX terminal on the well watch goes to pin 2 on the D connector, TX
goes to pin 3 and GND goes to pin 5. 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 Watch is 19200 baud, 8 data bits, 1 stop bit, no
parity, and no flow control. These settings can be changed from the menu as described
earlier.

The serial port is bi-directional and allows communication from the display unit to the
remote device and back. This allows some of the main settings to be changed from a
remote location. A standard terminal emulator program such as HyperTerminal
(included with windows) or Tera Term Pro (available for free download from
remote device and back. This allows some of the main settings to be changed from a
remote location. A standard terminal emulator program such as HyperTerminal
(included with windows) or Tera Term Pro (available for free download from
) can be used from a computer to operate the display unit or
view data remotely (see the section on remote operation).
The Well Watch display can also be instructed to automatically transmit new data over
the serial port as it is generated. Enable this feature from the RS232 SETUP menu as
described earlier.
