DATA LOGGER ON/OFF

The data logger uses communication strings to pass data through the serial port based on the values entered in
DATA LOGGER TRIGGER VALUE and DATA LOGGER TRIGGER UNITS. Whenever a value or console switch is
changed, data strings are sent by the console to the remote computer.
NOTE: When connecting to a Raven field computer, it is not necessary to turn the DATA LOGGER on.
Some options within the Data Menu are unavailable when certain other features are active. The console data
printout is not available when the data logger is on.
Remote Computer to SCS 440 Console Data Strings
All request strings begin with $R, indicating a Raven communication string.
Rate 1 Change Request = $R, RC, <rate_1_cal> <CR> <LF>
Calibration String Values Request = $R, CR <CR> <LF>
Data String Request = $R, DR <CR> <LF>

Used to set the maximum desired RPM or hydraulic output of the Pulse-Width
Modulated (PWM) control valve.
1. In the DATA MENU, use the arrow keys to advance to HIGH PWM OFFSET 253.
2. Move the product switch to MAN and the boom switches and master switch to
ON.
3. Hold the INC/DEC switch to increase the RPMs. If the motor exceeds the
desired RPMs, decrease the number by 10 and push INC again.
4. Decrease the 253 value displayed until the motor runs at the desired RPM.
5. Enter a number of 10 or greater.
6. Press the arrow up key to advance to LOW PWM OFFSET 1.
Used to set the minimum desired RPM or hydraulic output of the control valve.
Used to set the zero point or shut-off point of the PWM control valve.
1. In the DATA MENU, use the arrow keys to advance to LOW PWM OFFSET 1.
2. Move the product switch to MAN and the boom switches and master switch to
ON.
3. Hold the INC/DEC switch to decrease the RPMs until the motor stops.
4. Increase the value displayed until the motor runs at the desired RPMs.
5. Enter a number of 10 or fewer.
6. Hold the INC/DEC switch to decrease. If the motor does not stop, lower the
offset number by 10 and push DEC again.
7. Press the arrow up key to advance to LOW PWM OFFSET 1.
Used to enter the coil frequency of the PWM valve type being used. The default
frequency is 122 Hz.
Sequence to activate the data lock code, the feature that prohibits data entry
without the data lock code. The four-digit code must be entered within 15
seconds.
