GNSS antenna connector

for external GNSS anten-

(optional accessory)

SMB (male) - (antenna - female)

Supply voltage range 3.3 V

Minimum antenna gain at 3 V: 20 dB

Maximum antenna gain: 40 dB

Maximum noise rating: 1.5 dB

Bluetooth

Integrated Bluetooth

(class 2) for connection to Driver Terminals and acces-

sories.

1-Wire Interface A 4-pin MicroFit connector with 1-wire interface and LED current source (approx.

17 mA) for an indicator light is available. The 1-Wire master is using a 3.3 V sup-

ply.

Ignition input To be connected to the ignition clamp of the vehicle to switch on/off the device

with the vehicle ignition signal, if available.

Digital inputs 5 inputs switchable to supply voltage

Digital output 4 output switchable to ground (open drain)

CAN bus The three LINK 740 CAN bus interfaces are listen only CAN interfaces by de-

fault. In this mode, the CAN interfaces cannot block the connected CAN net-

work.

It is possible to switch every CAN Interface between listen only and full function-

ality by a DIP switch. The CAN DIP switch configuration can be read back by the

MCU.

5 PE power supply for external capacitive CAN sensors: For Webfleet Solutions ac-

cessories only. Please contact Webfleet Solutions Customer Support.

CAN3 is equipped with a switchable 120 Ohm load resistor.

CAN2 Low speed CAN port can be used alternatively as dedicated 5V output port

for contactless CAN sensor support.

CAN1H, CAN1L, High speed CAN

CAN2H, CAN2L, High speed CAN*

CAN2HLS, CAN2LLS, Low speed CAN*

CAN3H, CAN3L, High speed CAN

* Only one of the CAN2 ports can be used.

USB A Mini USB connector for service functionality, for example software update.

Powering the device over USB for service reasons is possible without cellular mo-

dem functionality.
