DuraNAV – Hardware Manual

Notes about the main power supply and ignition key:

The power supply section is made as follows:

• Input power filtering and protection circuitry, featuring a tranzorb to prevent over-voltages (load dump

up to pulses 10/1000μs with 1500W).

• DC/DC converters and regulators, ensuring the correct supply voltage to the board’s components.

• The control section that manages the whole power supply section.

An opto-isolated digital input acts as an “ignition key”: a voltage from 8.4 to 36.0 V DC needs to be applied to

pins 17 and 18 of connector M1 to enable the main system power.

For example, this can be part of the ignition key circuitry of a vehicle where the system is installed.

Power down is software managed.

Fuse

Figure 6. Power supply schematic

Note that a fuse must be present on the positive supply cable. This is a safety requirement that helps to

avoid damage to the device in case of mismatches or short-circuits.

The fuse should be a slow-blow with the following characteristics:

Characteristic Amperes Delay Time

12 Volt systems 4 Amps @ 24 Amps = 10 → 200ms

24 Volt systems 2 Amps @ 12 Amps = 10 → 200ms

For further information, refer to Power On and Power Off.

DuraNAV – Hardware Manual

Notes about the Digital I/O

Up to 4 Opto-isolated Digital Inputs and 4 Opto-isolated Digital Outputs are available on connector M1

Isolated Digital Inputs

Each of the digital inputs consists of a phototransistor, optically coupled to two infrared emitting diodes

connected inverse parallel.

The electrical levels are as follows:

Logical zero 0 V <= VIN_low <= 1.5 V

Logical one 10 V <= VIN_high <= 36.0 V

Note:

Do not exceed 36V between the positive and negative opto-coupler input pins

The Maximum propagation time from opto-isolated input to sampling digital input is 8 ms

The minimum detectable pulse length depends on:

• Polling method

• Better interrupt-based method

There is a programmable interrupt control block inside AC97 CODEC, which can generate an interrupt for 0-

to-1 and/or 1-to-0 transitions on one or more of digital inputs.

In both cases, the overall interrupt or polling rate depends on operating system, drivers and application

software.

Figure 7. Schematic of the Isolated Digital Inputs

DuraNAV – Hardware Manual

Isolated Digital Outputs

Four NPN opto-isolated digital outputs are available.

Outputs use a low-side switch scheme and can drive up to 33V and 200mA maximum.

Outputs have a common ground connection.

Electrical characteristics for Digital Outputs over working temperature range:

Maximum Drain Source voltage 36 V

Maximum Output ’Low’ voltage 0.4 V (at Id=200 mA)

Minimum Current limit 230 mA

Over-current protection intervention delay 5 us (typical)

Maximum propagation time from digital output to

opto-isolated open-drain

300 us

Note that DuraNAV has to be powered-off to recover from an over-current protection intervention.

Figure 8. Schematic of the Isolated Digital Outputs

Notes about the Identifier

The identifier line can be used to connect a Dallas/Maxim 1-wire EEPROM device, useful for identification

purposes.

The DuraNAV supports 1-Wire devices as DS2431, working at standard speed only.

The working voltage for I/O line is 5V.

Notes about the odometer:

The odometer line "ODOMETER_IN" is an opto-coupled counter input for odometer devices such as those

commonly used in vehicle speed measurement devices.

The negative reference "GND_ODOMETER" is a filtered ground connected to COMMON_DOE ground.

DuraNAV – Hardware Manual

Electrical Specification for input signal:

Voltage range: 0 ~ 36V

High / Low threshold: 2 ~ 20V software selectable

Maximum input frequency: 10kHz

Minimum High Time: 40us

Minimum Low Time: 40us

Odometer Supply:

A voltage output for an Odometer device is available on pin "ODOMETER_SUPPLY".

Note that common GND pins are used as reference for "ODOMETER_SUPPLY".

The voltage supply is jumper selectable between 5V and the "VIN+" (battery) voltage.

In both cases, the output current is protected over the threshold of 200mA.

Refer to The Jumpers and their functions paragraph for further information about the jumper selection.

Selection of threshold:

The odometer circuit compares the input signal with a software programmable threshold, and uses the

comparator output as the clock of a 16-bit counter.

The purpose of the programmable threshold is not to measure the value of the input voltage, but to allow the

system integrator to choose the best threshold value for his application.

First, the odometer input signal is applied to a resistor divider with a ratio of 1:4.7, with 100kOhm input

resistor. Then the signal is compared with a programmable reference voltage from 0 to 5V in 64 steps of

78mV each.

The programmable reference voltage comes from an EEPOT device, whose wiper position is programmed at

power-on and stored until next power-down or reprogramming.

Note that due to tolerances and rail limits, the lower and upper limits of reference voltage are not usable.

There are 55 usable threshold values, which correspond to wiper position from 6 to 60.

The comparator itself has 15mV of hysteresis for a clean transition.

On the following table, there are the allowed wiper position and the corresponding threshold, with a 4%

tolerance.

DuraNAV – Hardware Manual

Notes about the Audio Input and Audio Output signals

The DuraNAV includes some audio circuitry that is useful for typical vehicles applications. Here is a list of the

audio signals available and their use:

• MIC_IN/LINE_IN: this can be used for a Microphone or Line-in; the Microphone signal is fed to an

amplifier with gain selectable 1X or 10X. Then the signal goes into three audio recording inputs: the

Microphone input of AC97 CODEC, the Line input of the same AC97 CODEC, and the MIC1 input of

the GSM module. Use what best fit your needs.

For a short distance installation, a microphone can be connected using the MIC_IN and the other

signals MIC_SUPPLY and GND_MIC. For longer distances, the best approach is to input a Line-level

signal using an external amplifier.

• LINE-OUT-L and LINE-OUT-R: these can be used as Line-out for left and right speaker amplifier. This

signal comes directly from AC97 CODEC.

• HEADPH_L and HEADPH_R: these can be used to connect a pair of headphones. Audio signals that

come from the GSM or AC97 (see table 4) are fed to a dual audio power amplifier that is capable of

delivering 250mW per channel. The audio sources for left and right channels are different and

selectable, this gives the user an easy way to use the VOIP.

VOIP applications and Preferred use of Audio signals

The main problem when using VOIP is that the AC97 CODEC has to be used for public messages and the

(separate) private conversations of operator.

The separation of public messages and private conversations can be done on a channel basis (A) or on a

time-slot basis (B).

A: Separation on a Channel basis relies completely on software. Use the LINE-OUT-R or the HEADPH_R for

the public announces, and connected to external speakers. Use the LINE-OUT-L or the HEADPH_L for the

private conversations using VOIP, and connected to operator’s headphone.

Keep the signal MX_GSM_CODEC High. The stereo settings in AC97 Codec have to be separate, and the

audio file to be played has to be built separated and managed properly.

B: For the time-slot basis, the software uses the signal MX_GSM_CODEC to turn-off the Right speakers

when making a private conversations. Refer to the table below:

Signal MUX_GSM_CODEC = High MUX_GSM_CODEC = Low

HEADPH_L GSM AC97 Codec Line-out Left

HEADPH_R AC97 Codec Line-out Right None

Table 4. Audio source for HEADPH_L and HEADPH_R

When the application has to support the VOIP and wants to use the time-slot basis, use the Headphone

audio output in this way:

Use the HEADPH_R for the public announcements and connected to external speakers.

Use the HEADPH_L for the private conversations using VOIP and connected to operator’s headphone.

The software must set MUX_GSM_CODEC to high when playing a public message, and set

MUX_GSM_CODEC to low when making a call using VOIP. The stereo settings in AC97 CODEC can be

joined with the audio files to play and can be simple mono or stereo.
