MTU4 Page 5 of 14 Issue 1.11 MTU4 Technical Manual 1 Overview The Microlise Tracking Unit 4 (MTU4) is battery backed, vehicle tracking and telematics unit utilizing GPS, GSM / GPRS and Bluetooth technology. The unit is available in two hardware variants: a) MTU4-A with integral GSM and GPS antennas b) MTU4-B with SMA connectors for connecting external GSM and GPS antennas Units are supplied to customers pre-configured by Microlise with appropriate configurations along with wiring harnesses to suit the intended application. 2 Installation The MTU4 is designed for installation both within the vehicle cab and also for installation on a trailer. Depending on the application the device may be permanently powered (e.g. an in cab installation) or powered only periodically (e.g. in a trailer tracking application only when the trailer is hooked up to a tractor unit.) However, in either application the unit is designed to make efficient use of the power available through the use of sleep modes when there is no activity. When selecting a suitable mounting location, please be aware of: • Excessive temperatures (operating temperature: -25°C to 55°C) • Corrosive fluids • Areas where the unit may obstruct the drivers view or impede operation of the vehicle • Locations which may shield the unit and affect GPS and GPRS reception. If an external antenna is being used with the unit, then it should be located at least 30 cm from the MTU4 and any other ECU in the vehicle. Any excess antenna cable must not be tightly coiled up. The installation must be carried out in accordance with FCS1362:2010 or later, by a competent auto-electrician. GPS connection (MTU4-B only) GSM connection (MTU4-B only) Primary 48 way connection Secondary 32 way connection
MTU4 Page 6 of 14 Issue 1.11 MTU4 Technical Manual 3 Wiring For basic in cab installations only the following wires need be connected: MTU4 primary connector pin no Wire colour Signal In-line fuse* required P2M Red 12V or 24V supply 3A P3K Yellow Ignition 1A P4K Orange Engine run 1A P1M Black Ground None For bench testing, connect the red, yellow and orange wires to a +12V or 24V supply and the black wire to 0V / Ground. * Fuses and all replacements need to be automotive blade type ATO. 4 Description of operation Providing external power is applied, or the internal battery is sufficiently charged, and the unit is within GPS and GPRS coverage the unit will periodically (based on time and/or distance, and configuration) transmit location and telematics information to the relevant Microlise system. If out of GPRS coverage then messages are stored into non-volatile Flash memory for transmission later when a GPRS connection can be established. Whilst operating on external power the unit will charge the internal battery as required. Two CAN interfaces are incorporated which are typically used to either listen for, or request information on automotive CAN busses. The unit incorporates three RS232 interfaces which can be used for connection of a variety of peripherals, e.g. Mobile Data Terminals, refrigeration temperature monitoring equipment, printers, sensors or other devices. A Dallas 1 wire interface is provided. This is typically used for driver identification via Dallas iButtons, but could also be used with any other device in the “1 wire” range. Connection can be made to a vehicle Digital Tachograph via the built in digital tachograph interface. This can be as an alternative way to identify the driver and also capture information needed to comply with regulations regarding drivers’ hours. The unit incorporates seven digital inputs. Two are available for monitoring ignition status, another for engine run, the remainder are general purpose inputs which can be used for monitoring doors switches, panic buttons or other digital signals. A real time clock is incorporated for time-stamping all events recorded by the unit. The unit monitors its own internal temperature. Battery charging is only permitted when the temperature is within the specified limits of the battery pack. The Bluetooth interface can be used for diagnostics, for connection to peripheral devices, e.g. a data terminal, and also for audio connection to a Bluetooth car kit for hands free voice calls. A USB OTG (on the go) port is provided. This can also be used for diagnostics, but can also be used for connection to a range of USB host or slave devices. Using the built in Codec and a audio output via Bluetooth the unit can play tones or make audible announcements to the driver of a vehicle, e.g. to provide real time feedback on driving style. Depending on the device purchased, the unit is fitted with internal GSM and GPS antennas, or is provided with SMA connections to which separate, or a combined GSM/GPS, antennas may be connected. A microSD card may be fitted internal for applications requiring additional Flash storage capacity.
MTU4 Page 7 of 14 Issue 1.11 MTU4 Technical Manual Two relay outputs with change over contacts are provided for remote control of other devices. The built in accelerometer can be used to monitor harsh braking, acceleration, cornering, and any lean of the vehicle. The built in GSM modem supports four GSM frequency bands (850, 900, 1800 & 1900 MHz). The 900 and 1800 MHz bands are used in Europe, but are not operational in the USA. The 850 and 1900 MHz bands are the only bands used for GSM in the USA and Canada. 5 Antenna details 5.1 Bluetooth Both variants of the product (MTU4-A and MTU4-B) incorporate the Bluegiga WT32-A Bluetooth module. This module has a built in chip antenna with a peak gain of 1.5 dBi. 5.2 GSM The MTU4-A has a build in custom designed GSM antenna. This has a gain of 0 dBi. The MTU4-B has a SMA connection to which an external GSM antenna can be connected. A typical antenna is the Hirshmann GPS1890LP, the GSM gain of which is 0 dBi. Please note: To comply with FCC regulations the external antenna gain, including cable loss, must not exceed 3.0dBi at 1900 MHz / 1.4dBi at 850 MHz 6 Tuning and serviceable parts The MTU4 contains no user tunable parts. The MTU4 contains no user serviceable parts.
