Eno Scientific Well Watch 310 Page 13 WIRELESS OPERATION The Well Watch 310 display includes a built-in radio frequency (RF) transceiver for communicating with Well Watch 660 series well sounders. It uses a proprietary communication protocol operating at 2.405 GHz. There are 11 RF channels available provided both the display unit and the Well Watch are both set to the same channel. If the unit has difficulty communicating due to interference, try another channel. The default is set to 11 on both the display unit and the Well Watch. Each RF device using the channel is identified with an arbitrary address in the range 1-
254. The default is set to 6 on both the display unit and the Well Watch. Again, any address can be used provided it is the same in the Well Watch and display unit. Unless multiple Well Watch units are in use, this need not change. The transmission range of the transmitter is about 300 ft outdoors with an uninterrupted path. If the unit is indoors or obstructions exist in the path, the range will be reduced. Factors such as aluminum siding, metal lathe in stucco, or even low metalized coatings on windows will cause a significant reduction in range. Best results will be achieved when the unit is near a window or wood frame wall without much metal. Similarly for the Well Watch unit, if possible, try to place the unit at the well as high as possible and such that it can have a good unobstructed line of sight path to the display unit. If the Well Watch is installed in a metal pump house or below ground, the signal may not be strong enough to establish a link. WIRED OPERATION The Well Watch 310 display also includes a built-in RS485 transceiver for communicating with Well Watch 660 series well sounders. It acts as a modbus master using a proprietary protocol, and will not work with other modbus devices. The RS485 connection requires three conductors to operate, 2 conductors and a ground. Shielded cable is recommended, in which case the shield should be used as the GND connection. A wired connection is more reliable than RF and has the ability to communicate at distances up to 2000 ft regardless of obstructions. An additional benefit is that with one additional conductor, power may also be supplied to the Well Watch unit. Eno Scientific Well Watch 310 Page 14 If a wired connection is to be used, then the RS485 A and B terminals of the display unit need to be connected to the corresponding terminals on the Well Watch A to A, and B to B. The GND terminals must also be connected. Shielded cable is recommended, in which case the shield should be used as the GND connection. If the Well Watch is to be powered from the display unit, then connect the 7-12VDC terminal on the display unit to the PWR terminal on the Well Watch. The RS485 bus, like the RF, has the ability to communicate with multiple devices on the same wires. An address is therefore required so that a specific device can be accessed. The same address must be selected in the display unit as in the Well Watch 660. LOGGING The Well Watch 310 display includes a built-in data logger which can record the measurement data automatically at preset intervals when automatic logging is enabled. Each data point includes the system time and date, and depth. The data is recorded in the internal flash memory which maintains the data even if the battery goes dead. The internal memory is large enough to hold more than 25 million data points. This memory is only accessible using the USB interface as described in the next section. To automatically log data on a schedule, enable logging as described above on the LOGGING ENABLE menu. Three logging modes are available: Disable, Enable or Change. Enable sets the unit to record data each logging period. Change sets the unit to compare data each period against the last logged data point. The new data point is stored in memory if the measurement has changed more than the log change margin
(as defined in the Change menu). If logging has been selected, then the LOG PERIOD menu becomes available to set the time interval between logged data points. And if change was selected, then the CHANGE menu also becomes available to set the amount of level change required to log a new data point. If the log period is set to 2 minutes, the Well Watch display unit 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. USB COMMUNICATIONS Eno Scientific Well Watch 310 Page 15 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 http://www.logmett.com) 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. Eno Scientific Well Watch 310 Page 16 REMOTE SERIAL OPERATION OVER RS232 When the Well Watch display is connected to a computer or other bi-directional remote device, the display unit can be controlled and configured using a set of simple commands. If using a terminal emulator on the computer, establish a connection between the computer and the display selecting the COM port connected to the display. If your computer has a built-in com port, it will probably be COM1. If you are using a USB adapter it may be any where from COM3 thru COM12. Then enter the port settings:
19200 baud, 8 data bits, parity none, 1 stop bit, and flow control none. Turn on the Well Watch display and press the <return> key on your computer. If it is set up correctly, the display will return with a line of data and a WS310> prompt on the screen. If the Well Watch display does not respond, select a different COM port and try again. Once the connection has been established, commands can be send from the computer to the Well Watch. The remote commands are case sensitive and must be entered exactly as shown on the list below. One command per line, terminated by a <return>. Extra tabs or spaces will not be accepted. Examples:
Press "s1<return>" to enable continuous transmission of data on the RS232 port. Press "u0<return>" to set english units mode or "u2<return>" to set metric. If serial output is enabled, the prompt and input may be written over on the screen but the input will still be interpreted correctly. It may be easier to disable the serial output while using remote commands. Press s0<return> to turn off serial reporting and s1<return> to turn in back on when finished. USER REMOTE COMMANDS - In the following list, [iiii] indicates a parameter of up to a 4 character integer (no decimal point), [ddddd] indicates up to 5 character decimal number (decimal point optional), [cc] indicates two nonnumeric characters, and <ret>
