See Pinout Table below.
Setup: 9600, n, 8, 1.
Start HyperTerminal.
Power up the ES-22 board.
Press "M" to enter the menu system.
The following menu will appear:
Note: If the board are in the free-run mode, it will
print data to the screen at one sec interval.
Turn off by typing "C", This toggles "Con't run" on/off as shown below:

• Ser:01 PIN:#### Board:ES-22 Mode:Polling
• M - Menu
• C - Con't run - Toggle on/off
• V - Change free run interval
• D - Default mode - free run/poll
• S - Single sample output
• A - Auto-Zero : 12-bit A/D
• X - FSO : 12-bit A/D
• R - Reset Ah-Counters & lamps
• T - Time
• P - PIN Code
• L - List data
• E - Erase List

Typing "M" will show the ES22 menu.
The first line contains The board serial number, the active PIN-code, and active mode.
Typing "C" Toggles between "free-run" mode and "Polled mode".
In "Polled mode", the board will send out a data string to a call.
The char "S" is used here.
In "free run" mode the board are sending continously, with no need for a call.
Note that the logg functions are not interupted, and will run in the background, as normal.
The default setting are "Polled mode".
This can be changed by typing a char "D", and entered into the parameter memory, and recalled later at startup,
even if the power has been lost.
The "free run" interval can be altered in the "V" menu. This value can not be saved, but will
be active untill a new value are entered or the power is removed.
The default interval setting are 1 sec.

Typing "A" will sample any voltage present at the 12bit inputs, and memorise it for a new reference.
This function makes it possible to null out an offset voltage, and make it a relative zero.
The value will stay in memory until a new value are entered.
Typing "X" will enable modification of the Full Scale Output (FSO) value.
This value sets the maxVal for a full scale A/D converter input (5V).
Set to 15, the outVal will be 15.00V at 5.0V input. The same are true for the Amp input,
as all A/D Converter inputs accepts a 0 to 5V full scale input signal.
