TN: 08040456 Installing BT-5000 series modems into vehicles IMPORTANT Any installations involving electrical wiring and connections should be done by someone who is experienced in this field. Power Source: To power the modem, a 12 VDC nominal power (8Vdc to 30Vdc) source is required. The modem package includes a 15 foot power cable with 2A inline fuse with, on one end, a 4pin Molex MiniFit connector that connects to the modem, and stripped wires on the other end to connect to your power source. The ignition sense line (white wire) acts as an ON/OFF power switch. The modem will turn on when the ignition sense line is set between 8 and 30 volts DC. The modem will turn off if the ignition sense line is less than 5 volts DC. Figure 19 – Power cable Connect. Monitor.

Connect the black wire directly to the battery’s negative (-) terminal or to ground (GND) The white wire must be connected to either: o The red wire to keep the modem powered on when there is power o A switch for manually turning on and off the modem o The vehicle’s “Accessory for position 2”, for turning ON the modem without turning on the engine. o The vehicle’s “Accessory for position 3”, for turning ON the modem only when the engine is turned on. Testing the Connection: Check the PWR light on the modem: if it is turned on then the modem is powered. If it’s off, then review the installation procedures. If LED indicators are not accessible to the installer, a personal computer can be used to verify it’s functionality by running BlueVue Device Manager and attempt to connect to the modem. Connect.

It should be noted that the I/Os of the modem are not insulated. Caution must be used in order to avoid causing damage to the modem and its attached peripherals. The 15foot 10pin I/O cable is available for purchase from BlueTree. The Molex plug shown in the figure below is found at one end of the cable, and stripped wires are found at the other end for easy connection to your equipment or sensors.

Connect the negative side of the analog source to GND. 2. Connect the positive side of the analog source (0VDC – 5VDC) to one of the digital inputs 3. These analog inputs are not designed to detect a signal at high speed. This approach was adopted to minimize the errors which could be caused by the noise of high frequencies captured by wiring. The detection of a DC source with a slow variation will not cause any problems. Connect. Monitor. Control.
