| − | <big>'''Connecting Wires'''<br /></big>
| |
| | | | |
| − | • Wires should be connected while module is not plugged in.<br />
| |
| − |
| |
| − | • Wires should be fastened to the other wires or non-moving parts. Try to avoid heat
| |
| − | emitting and moving objects near the wires.<br />
| |
| − |
| |
| − | • The connections should not be seen very clearly. If factory isolation was removed while
| |
| − | connecting wires, it should be applied again.<br />
| |
| − |
| |
| − | • If the wires are placed in the exterior or in places where they can be damaged or exposed
| |
| − | to heat, humidity, dirt, etc., additional isolation should be applied.<br />
| |
| − |
| |
| − | • Wires cannot be connected to the board computers or control units.<br /><br />

| − | <big>'''Connecting Power Source'''<br /></big>
| |
| − |
| |
| − | • Be sure that after the car computer falls asleep, power is still available on chosen wire.
| |
| − | Depending on car, this may happen in 5 to 30 minutes period.<br />
| |
| − |
| |
| − | • When module is connected, be sure to measure voltage again if it did not decrease.<br />
| |
| − |
| |
| − | • It is recommended to connect to the main power cable in the fuse box.<br />
| |
| − |
| |
| − | • Use 3A, 125V external fuse.<br /><br />

| |
| − | '''Connecting Ignition Wire'''<br /></big>
| |
| − |
| |
| − | • Be sure to check if it is a real ignition wire – power does not disappear while starting the
| |
| − | engine.<br />
| |
| − |
| |
| − | • Check if this is not an ACC wire (when key is in the first position, most electronics of the
| |
| − | vehicle are available).<br />
| |
| − |
| |
| − | • Check if power is still available when you turn off any of vehicles devices.<br />
| |
| − |
| |
| − | • Ignition is connected to the ignition relay output. As alternative, any other relay, which has
| |
| − | power output, when ignition is on, may be chosen.<br /><br />
| |
| − |
| |
| − |
| |
| − | <big>'''Connecting Ground Wire'''<br /></big>
| |
| − |
| |
| − | • Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.<br />
| |
| − |
| |
| − | • If the wire is fixed with the bolt, the loop must be connected to the end of the wire.<br />
| |
| − |
| |
| − | • For better contact scrub paint from the place where loop is connected.<br /><br />

| |
| − | ''<nowiki>PAY ATTENTION! Connecting the power supply must be carried out in a
| |
| − | very low impedance point on-board vehicle network. These points in the car
| |
| − | are the battery terminals. Therefore, we recommend connecting the power of
| |
| − | FMB640 (wire GND and POWER) directly to the battery terminals. Another valid
| |
| − | option is to connect the wires to the main POWER cable inside the fuse box (if
| |
| − | there is none, then to the power supply where the fuses of vehicle’s computer
| |
| − | are), wire GND must be connected in a special point, designed to connect GND
| |
| − | vehicle computer. Connecting the GND at an arbitrary point to the mass of the
| |
| − | car is unacceptable, as static and dynamic potentials on the line GND will be
| |
| − | unpredictable, which can lead to unstable FMB640 and even its failure.</nowiki><br /><br />''

| − | <big>'''Connecting Antennas'''<br /></big>
| |
| − |
| |
| − | • Gently connect antennas to device by hands, without using additional equipment like
| |
| − | pliers. The tightening torque for fixing the connector must be up to 0.5 – 0.7 Nm (‘handtightened’).<br />
| |
| − |
| |
| − | • When placing antennas avoid easily reached places.<br />
| |
| − |
| |
| − | • Avoid GNSS antenna placement under metal surfaces.<br />
| |
| − |
| |
| − | • Avoid placing FMB640 device near car radio, speakers or alarm systems.<br />
| |
| − |
| |
| − | • GNSS antenna must be placed so its state is as horizontal as possible (if antenna is leant
| |
| − | more than 30 degrees, it is considered incorrect mounting).<br />
| |
| − |
| |
| − | • GNSS antenna cable cannot be bent more than 80 degrees.<br />
| |
| − |
| |
| − | • GNSS antenna must be placed sticker facing down.<br />
| |
| − |
| |
| − | It is recommended to place GNSS antenna behind dashboard as close to the window as
| |
| − | possible. A good example of GNSS antenna placement is displayed in a picture below (area
| |
| − | colored green).<br />

| |
| − |
| |
| − | • Module should not be seen or easily reached.<br />
| |
| − |
| |
| − | • Module should be firmly fixed to the surface or cables.<br />
| |
| − |
| |
| − | • Module cannot be fixed to heat emitting or moving parts.<br />
| |
| − |
| |
| − | • SIM card should be inserted in the module while the connector is plugged off (while
| |
| − | module has no power).<br />
