RS232 COMMUNICATIONS
The Well Watch 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 TX terminal on the well watch goes to pin 2 on the D connector, RX 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 set screen on the keypad.

The serial port is bi-directional and allows communication from the Well Watch to the
remote device and back. This allows the Well Watch to be programmed and operated
from a remote location. The Well Watch offers a complete command set over the serial
link to allow configuring the Well Watch settings. A standard terminal emulator program

Well Watch remotely (see the section on remote operation).
The Well Watch can also be instructed to automatically transmit new data over the
serial port as it is generated. To activate this feature from the keypad, press the SET
button until RS232 data is displayed. Press the UP or DOWN button to select
continuous, or depth only. When set to continuous, the complete data set is transmitted
with each pulse. When set to depth only, only the depth is transmitted.

If using a terminal emulator on the computer, establish a connection with the Well
Watch by selecting the COM port connected to the Well Watch. 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
