[. . . ] feet/miles/kilos pulse is ON) 12 V PDI CONNECTION See P/N 1050 Manual. SETTING PDI DISTANCE (i. e. feet/miles/kilos between pulses) STEP 1 : Set the measurement units, (feet, miles or KM), you wish to use for your PDI distance. Even though the default "1" appears, you must re-enter the required PDI Distance number and press MARK/ENTR. STEP 2 : Next, press the following keys: 8PDI key, 2UNIT key (DISTANCE), MARK/ENTR key. STEP 1 : Press the following keys: 8PDI key, 3PD key, DISP/HOLD key, (DISTANCE) MARK/ENTR key. 20 21 STEP 2 : At the PLEN prompt, enter the length in current units you would like your pulse to be on. The length duration will have an error = +/- CALIBRATION NO. /1000 FEET. If you had a calibration number of 800, your PDI pulse duration would be your set length +/- 0. 8 FOOT. If you had a calibration # of 700 your max duration would be: MAX Duration = 32, 768* 700/1000 = 22, 958 Feet. or 0. 044 km If you enter a value over this it will fold your input value back down into this range. The output shown below is for Low Going High: HIGH GOING LOW If you want the output normally low ( 0 volts) and pulsing LOW at each PDI distance depress the following sequence of keys: 8PDI key, 5BRIGHTNESS key, MARK/ENTR key. IMPORTANT NOTE: Do not set this length greater than the PDI distance. If you have a PDI distance of 100 feet, do not set the duration to 200 feet. The output shown below is for High Going Low: SETTING THE TYPE OF PDI The device that uses the PDI signal sometimes has certain requirements for the signal. Let us take for example a PDI set for every 10 feet and a duration of 1 millisecond. LOW GOING HIGH (DEFAULT SETTING) The default setting would be with the output normally low (0 volts) and pulsing high at each PDI distance. If you want to return to this default setting depress the following sequence of keys: 8PDI key, 6PRINT key, MARK/ENTR key. FLIP FLOP If you want to set FLIP/FLOP high on every other 10 ft stretch depress the following sequence of keys: 8PDI key, 4UP/DOWN key, MARK/ENTR key. 22 23 . . . and your output would be: SET COUNT PRE-DISTANCE To have your PDI count to start at a value other than 0 depress the following sequence of keys: 8PDI key, 8PDI key again, (ENTER PREDISTANCE VALUE), MARK/ENTR key. The value will appear in the INTERVAL window. SUMMARY PDI KEYS Note that the duration does not apply to this one, it just alternates HIGH & LOW on each PDI distance. First Press 8PDI and then: 2. ) - Set PDI Distance 3. ) - Set PDI Duration by TIME 3. ) - Set PDI Duration by DISTANCE - (DISP/HOLD) 4. ) - Set Flip/Flop PDI (High then low on alternate PDI distances) 5. ) - Set HIGH going LOW signal 6. ) - Set LOW going HIGH (Standard) 7. ) - Set distance increment for PDI Count dis play 8. ) - Set initial value for PDI Count display CLEAR - Turn OFF PDI (& PDI count display)PDI ADVANCED PDI USES As pre-mentioned a count of the PDI pulses can be displayed in the INTERVAL window. The INTERVAL window will then display the Starting Value and then with the vehicle moving and the COUNT/HOLD off, the INTERVAL window will display the Count Increment value as derived from the PDI pulse output. PDI COUNT USE An example will make this function a little clearer. When a person calls for help, the Emergency Response Center can, via phone company equipment, determine the phone number of the caller. The Emergency Response Center can then dispatch police, fire or ambulance teams to handle the problem. This may work well except in rural areas when the addresses are undefined or Rural Route box numbers. Rural governments are solving this problem by naming all their roads (and putting up signs) and assigning addresses to the houses on these roads. The phone numbers are then associated with a street address that police, fireman and ambulance drivers can find. Each house can not be numbered consecutively since new houses will probably be built between existing houses and these places will need numbers. If a standard lot width is determined (say 50') then every 50 feet assign a new address. [. . . ] If you have any questions, please call for Technical support at (724) 438-8750. If you return your DMI always include a note with your Name, Address (Both street and P. O Box) and a telephone number so that we can contact you if necessary. 38 39 HYPERTERMINAL SET-UP FOR NS-60 Hyperterminal is a terminal emulation program that comes built into Windows.
