ETA by Abie Baker ESTIMATED TIME of ARRIVAL This document will show how to use the ETA file and its associated MPHDIR directory. 1. Load both the ETA directory and the MPHDIR directory into your 48. 1A. Load "Beeper" into the HOME directory. 2. The MPHDIR can be ORDERed to the end of your directory if you would like, as it is the actual running programs and data storage buffers. PROCEDURE 3. Press the ETA directory key. "TRIP" "DISPL" "ODO" "ET" STOP" "STRTD" will come up one page one. Press NXT and on page two will be "STPDS" "SETBE" "INI" "CLRBE" "LSTPR". 3A. TRIP, is used to input miles traveled thus far, via a trip odometer, or known distance. DISPL, puts the latest TRIP or ODO screen on the display. ODO, this works the same as "trip", except you input your distance as an odometer reading. This is usually done if you have an older vehicle that does not have a trip odometer. ET, press this at any time to get the current Elapsed Time since you press the Start button. STOP, this is pressed when you reach your destination. Input of ending odometer reading is required. STRTD, this simply displays again, the very first starting screen. STPDS, this simply displays the Stop screen again, if Stop has been pressed. SETBE, this asks for an input in minutes, and then sets a repeating Beeper so that reading can be taken at a constant interval. INI, this is the cautious one. This Initializes everything. Press this just before starting your trip. CLRBE, this Clears the interval Beeper set with SETBE. Simply press and the interval is deleted. LSTPR, this is used after your trip and if you were unable to print your reading as you input them. This will print all the readings you took and the StopDisplay. 4. Start ETA by pushing the "INI" key on page two. 5. You will then be asked to input your PRESENT ODOMETER READING. Input that value and press ENTER. 6. You will now be asked your APPROX. MILES TO DESTINATION. Input this value, to the best of your knowledge. Press ENTER. 7. You will now see a "START or ABORT" screen and the softkeys will also show START or ABORT. As you are ready to start your actual trip, press START. ABORT will abort the program from here. 8. As soon as START is pressed you will see another screen that shows your START TIME:, START DATE:, & STARTING ODO:. At the bottom the softkeys will ask for you to press "PRINT" or "DONE". If you have one of the IR printers for the 48, aim the 48 at the printer and press "PRINT". If you do not have a printer, press "DONE". You will now return to your original stack screen. Notice though that the softkeys will display page one of the ETA directory. 9. At this time you may use any of the keys you would like on page one, except STOP. DO NOT push STOP until you are at your destination. 9a. Pressing "ET" will give you the Elapsed time since you started your trip. Pressing the ON key, or ATTN key will clear this screen, if you would like but it is not necessary. 9b. Use the "TRIP" key by first putting the miles traveled thus far according to your TRIP ODOMETER if you have one, then press "TRIP". Of course this should be as precise as possible. You will then get a new screen with your present MPH, change in MPH (a positive value is an increase and a negative value is a decrease), next will be your ETA with day, date, and time. Fourth will be the Estimated time yet to travel. Or your remaining driving time, if you make no stops and speed does not change. If any of this changes, then it will be reflected the next time you input a new TRIP or ODO reading. The fifth line is your Miles traveled thus far. Sixth is the miles YET to travel. Seventh is the Elapsed time since you started your trip or at least stared this program. Eighth is the current date and time that you took this reading. Good to keep a printed record. Last is the estimated Total travel time. This is a total of time so far and time remaining. At this point you are asked to press a softkey. "PRINT" or "QUIT". If you have a printer, it would be nice to print a copy. When you get to your destination you will be able to look at all the data and see how you've done. If you do not have a printer or not with you press "QUIT" to quit this screen. You may go back at any time and press the "DISP" key to review the last "TRIP" or "ODO" screen. If you do not have a printer with you, your data is saved in the "lststo" buffer for later printing, as long as you do NOT do another INIT. 9c. If you do not have a trip odometer, use the "ODO" key. This is done the same as 9b except you input your current odometer reading and press "ODO". Everything else will be the same as 9b. 9d. If you are going on a rather long trip and would like to take ETA reading at a consistent interval, use the "SETBE" key. This is for SETBEEP. It will ask you the interval, in minutes, that you would like to be beeped. At the end of each interval you will hear the 48 beep you and ask for input. If you would like to shut the beeper off, press the "CLRBE" softkey. This is the clearbeep key. The setbeep will be automatically cleared. If you have SETBEEP turned on, it will also be automatically cleared when STOP is pressed. 9e. This is the STOP key. Press this precisely when you arrive at your destination. The current date and time will be logged as soon as the STOP key is pressed. You will now be asked to input your final or ending odometer reading. Do so, then press ENTER. There is NO hurry here as your ending date and time are already logged. Just be sure to input the correct ENDING ODOMETER reading. The only thing that must be as precise, besides the actual pressing of the STOP key is you ending odometer reading. Once this is input, you will get a STOPDISPLAY screen. It will show your STARTING TIME, STARTING DATE, STOP TIME, STOP DATE, DISTANCE TRAVELED, ELAPSED TIME, AVE. SPEED, Your last ETA and the error, due to driving to fast, or driving to slow or an incorrect estimated destination mileage. But you will now have the actual mileage from your start point to your end point now. Print this screen if you have a printer, else press DONE. 10. Once STOP is pressed, the ET key will now show not only Elapsed time for the trip, but total elapsed time since last starting this program. This could be hundreds of hours. 11. A buffer containing your most recent displays are now also saved for later printing. When you are have "STOPed" simply press the "LSTPR" key on page two, and follow the directions. "DONE" will be displayed when the buffer is fully printed.Once again the default to print is to the IR printer, since this is portable. Feel free to add more output to this buffer. It is very straight forward. 12. ***** Please use care when operating this program and driving. It would always be nice to have a second party with you to help input the data for you and print each screen as you travel. * A special thanks to James Donnelly for his TOOL KIT and in particular his TOOL LIBRARY without which this program could not display each screen so very nicely. ** This is a first pass and a quick one at that, so feel free to make comments and changes. It is written entirely in normal user code on the 48. This way quick edit changes can be made if desired. Note that the MPHDIR is never needed by the user. Only by the ETA directory. There are a lot of variables. This is so that data can be as accurate as possible, both now and at a later date.
