Internal back-up battery automatically switches online when the vehicle’s battery voltage reaches 10.0 VDC. Vehicle battery auto-reconnects when vehicle voltage reaches 11.5 VDC or higher. • Internal Battery Charger • Built-in, 3-Stage temperature compensated battery charger maintains internal battery at full charge, ready to provide back up power for an extended period. • Noise filter eliminates electronic noise and interference, providing clean power required by mobile electronics for proper operation. • Overvoltage transient protection prevents damage to sensitive circuitry due to voltage line spikes. • When activated, load disconnect timer (TMR) eliminates dead vehicle batteries caused by power drain from radios and mobile data terminals that must operate while the engine is off. Allows use of accessory loads per programmed time limit (user adjustable) while preserving battery for emergency starting. Factory default is not active, see page 5.

Page 4: Operational Features Summary
MATERIALS PROVIDED The MDP-25.0 is supplied with the following materials: (4) # 8 ring lugs for 8 gauge wire (1) Terminal block cover (attached) (1) Installation/Operation Manual Check to see that these have been included with the packaging. For any missing items, please contact Factory. INSTALLATION Mechanical: Locate a flat surface close to the power line that feeds the electronics. For best results, the MDP should be within 24” of the critical electronics. -

Motorola Output Signals: The MDP is programmed to provide early warning signals to mobile data computers designed for this input (such as Motorola® MW 800 Series workstations and video recording system cameras .) Interface signals for this output is located on the D-sub 9 pin connector per the following pin out (please contact factory for mating connector with pigtails, part number 425-5233-0): Fig. 2: Input/Output Signals (D-Sub 9 Pin) - Motorola Apps. Signal Key: Ignition OUT 1) Ignition OUT: to be connected to MDT interface with signal which initiates Not Used Ignition IN startup and shutdown sequence of computer. -

1 hour after which the charger is turned off. The charger will periodically re-start to top off the battery. (The charger re-start time interval is adjustable, see Advanced Settings page 7). Complete charging cycle of fully discharged battery is approximately 3-4 hrs. Charger over-temperature protection: The battery charger circuit will automatically switch to reduced float voltage if the MDP internal temperature reaches 55° C. The over-temperature protect circuit will automatically reset once internal temperature reduces to approximately 50° C Disconnect Timer (TMR) Operation The MDP-25.0 incorporates an optional timed load disconnect feature (TMR). When activated the timer will begin timing when the vehicle battery drops to 12.0 VDC or less. If the ignition override feature is wired to the ignition switch (J1 pin 2, ‘Ignition IN’), it will disable the TMR timed disconnect as soon as it senses 2 volts or greater. To enable the TMR feature and select a disconnect time period via the DIP switches, you must do following: P.O. Box 1306 Phone: 714-751-0488... - Page 7 1. If the MDP-25.0 is already installed, turn off all 12 volt loads connected to the output and disconnect the 12 volt input. If unable to remove power first, make the DIP switch changes and then capture the changes by pressing the RESET button once. 2. Access the DIP switches by removing two Phillips head srews securing the access plate located on the side of the unit (left side if looking at the front of MDP).

Back-Up Trigger Voltage 10.5V Back-Up Hysteresis Charger Re-Start Interval 6 hrs. 1. DIP switch group S5, switch numbers 1 - 3 are for changing the Back-Up Timer Interval (See Table 2). This adjustment sets the amount of time the MDP’s internal back-up battery remains connected to the output/load when a low voltage event is detected. 2. DIP switch group S5, switch numbers 4 - 6 are for changing the Back-Up Trigger Voltage Threshold (See Table 3). This adjustment sets the voltage at where the internal battery is applied to the output/load and the input source (vehicle battery) is disconnected.

When connecting or reconnecting input power to the MDP it is normal for the “INPUT CONNECTED” LED & “BACK- UP POWER” LED to both illimunate for 2-3 seconds. 3) Charging LED: a) It is normal for the CHARGING LED to extinguish when the three stage charger goes in to sleep mode. (Sleep mode reduces MDP input current draw when the internal battery is full charged.) If fuses blow repeatedly, this usually indicates a shorted component. Contact NEWMAR for further trouble shooting advice. Always verify that the replaced fuses are of the correct rating. Use standard ATC fuses. Do no use slow-blow fuses. c) Flashing Red LED - internal charging temperature exceeds 50° C. FACTORY CONTACT INFORMATION If a problem persists after you have applied the above-outlined solutions, or if you have any questions about the installation and proper operation of the MDP-25.0, please contact NEWMAR’s Technical Services Manager: Phone: 714-751-0488 - From the hours of 7:00 A.M. to 4:30 P.M. weekdays, P.S.T.
