Introduction

The IT controller for 4G communication is a location information communication terminal device with packet data communication function of 4G/3G/GSM system and GPS receiving function (L1 1.5GHz band). It uses TCP/IP/PPP as the communication protocol.

Overview

Supported Frequency Bands

Output Power

Configuration

Note 1: The scope of our quality assurance for the communication module is limited to the isolation of whether problems caused by the communication module or not. The quality assurance of the communication module is to be performed by Telit. Therefore, we will ask Telit to conduct a detailed analysis of the cause of the problem and to confirm the spread of the defective lot.

Note 2: The built-in battery pack is warranted for 1 year for function and 3 months for performance. Please replace the battery pack on a regular basis. If periodic replacement is difficult, the performance of the battery itself may deteriorate or the battery may malfunction, which may cause the emergency call function not to operate when the heavy equipment battery is removed. In addition, do not use metal products (tools, etc.) when removing and installing the battery connector. The battery may short-circuit, resulting in excessive current flow, which may cause the battery to overheat, rupture, leak, or damage the equipment.

Note 3: The built-in battery pack must be restored to a fully charged state by replenishing (charging) power to the built-in battery pack when external power is supplied. If no power replenishment continues, the remaining capacity of the built-in battery pack may decrease or become empty.

Configuration Diagram

The diagram shows the following components and their connections:

• IT Controller (JRN-340K): The central unit.
• Communication Module: Connected to the IT Controller.
• Built-in battery pack: Connected to the IT Controller.
• eSIM: Connected to the IT Controller.
• LTE antenna: Connected to the IT Controller.
• GPS antenna: Connected to the IT Controller.
• Power supply and control unit: Provides power.
• Mechatronic I/F cable: Connects to the Mechatronic Controller and Vehicle batteries (via a fuse).

Note 1: Please prepare mechatronic I/F cables by customer.

Note 2: A fuse (recommended current rating: 2[A]) is required for the mechatronic I/F cable to protect against overcurrent. Fuses should be inserted at two locations: battery and GND.

Note 3: Do not take main power from a DC cigar. Poor contact may cause malfunction.

Functions

(1) Operation during key OFF

• Periodic batches are performed at the specified time.
• The server responds to the call from the server side.
• Acquire current location information by GPS and generate out-of-area alerts.

(2) Standby (power saving) control function

Return from standby (power saving) is as follows:

*Set to allow return by the following interrupt when shifting to standby:

• CAN1_EN/CAN2_EN (Engine Key) ON from mechatronics
• Detect ACC ON↔OFF change
• Interrupt by RING0 signal from communication module
• Date and time notification return by date and time setting
• UART (serial data) receiving from PC
• Charge signal (HOUR_METER) ON

When the device is restored from standby, the application is notified of the restoration. Shift to standby follows the instruction from the application.

The receiving interval of intermittent receiving varies according to the DRX (Discontinuous receiving) value specified by the communication operator as follows. (DRX is specified from 32 to 256)
Receive interval: 10 ms * DRX value.
Every 0.32 seconds for DRX=32
Every 0.64 seconds for DRX=64
Every 1.28 seconds for DRX=128
Every 2.56 seconds for DRX=256
(*) When out of range, the standby current increases due to carrier search.
