5.0 Installation

The i50 is designed to be installed inside a vehicle or other asset. It operates over a wide

temperature range (-20C to 50C), but should not be placed in an engine compartment or anywhere

temperatures can exceed the operating values. An external case is recommended if operating the

unit in wet or dusty environments. See section 3.0 for detailed specifications.

5.1 Device Orientation

The i50 may be installed in any orientation. However, if the optional internal accelerometer is being

used to detect high g-forces, the mounting angles must first be set. See section 9.0 for details on

configuring the accelerometer.

5.2 Power Supply

Connect the i50 ground line to vehicle ground (or negative battery terminal). Then connect the power

line to a continuous voltage source (or positive battery terminal). Make sure to select a voltage

source that remains active while the vehicle starter motor is engaged. It is recommended to use an

external 5 amp fuse on the power line.

Connect the VOUT line to any device you want to power up while the i50 is awake. This is commonly

used to power an external data terminal such as the Datalink Mobile Data Terminal (MDT).

5.3 I/O Connections

The i50 will operate successfully with only power and ground I/O connections. In this configuration, it

can be set to use battery voltage to detect engine running, and use its accelerometer to detect motion

to wake up from sleep.

However, it is recommended to connect the IGN input to a vehicle ignition source (high voltage only

when ignition is turned on). The i50 can then be configured to wake up and go to sleep as IGN is

turned on or off.

If accurate engine hour calculations are required, the default method of using battery voltage to

detect engine running may not be reliable enough. In this case, one i50 input can be configured as an

“Engine On” input, and connected to a vehicle circuit that is active only while engine is on (oil

pressure, fuel pump, etc).

See section 13.0 for more information about Input configuration.

You can also use the i50 digital outputs to control external circuits. These outputs can be controlled

remotely, and maintain their state while the i50 is sleeping.

5.4 COM Connections

Use the three serial ports (COM1, COM2, and COM3) to connect external RS-232 devices to the i50.

These ports are commonly used to connect modems or external data sources.
