The ISAAC InMetrics is a stand-alone data recorder for ISAAC Instruments vehicle telemetry and a wireless Internet access point. It captures and transmits the data collected from sensors and the vehicles CAN bus to the vehicle telemetry server, and also provides wireless connectivity for external devices such as the ISAAC InControl rugged tablet and ISAAC InView camera solution. The built-in components of the ISAAC InMetrics feature a GNSS, and allow for cellular, Wi-Fi and Bluetooth communication. The ISAAC InMetrics allows connecting a communication module (ex. satellite Iridium), IDN modules (ISAAC Device Network) and 4 digital inputs. Internal sensors 3 accelerometers and gyroscopes for measuring forces on lateral, longitudinal and vertical axes Temperature and voltage. External ports Diagnostic ports

The recorder also includes protection against reverse polarity and supply over-voltage. In the event of reverse polarity ( 70 V) or voltage outside operating range (32 70 V), the recorder automatically shuts down to avoid damage, and resumes operation when voltage returns to operating range. EMI/RFI and Electrostatic Discharge Protection All power and signal wires connected to the system are shielded and filtered against electromagnetic/radio frequency interference to offer excellent data collection in highly radiated environments. ISAAC Instruments recorders and peripherals undergo rigorous EMI/RFI testing to ensure system reliability in the harshest environments. Vehicle Data Ports (CAN) The CAN 2.0 A/2.0B ports are capable of recording information from:
Diagnostic on CAN (ISO 15765)
- OBD on CAN SAE J1979
SAE J1939 CAN Bus compatible electronic devices Single frame broadcast messages with standard (11 bit) or extended (29 bit) identifiers The SAE J1708 port is capable of recording information from SAE J1708/SAE J1587 and SAE J1922 data links. Note: only 3 diagnostic ports can be activated simultaneously Internal Accelerometers and Gyroscopes The 3 accelerometers and gyroscopes measure the longitudinal, lateral and vertical forces the recorder is subjected to. Digital Inputs The input measures the state of an input. The recorder can be configured to apply pull-up (default) or pull-down resistance:
Use pull-up when signal input switches to 0 V (GND) Use pull-down when signal input switches to +V Shutdown Timer The recorder features a shutdown timer that can be used to automatically power off the recorder after a set amount of time, in order to avoid battery drainage. The shutdown timer delay is configurable. Shutdown timer logic:
- When ground or an open signal is detected to the SHTDWN cable, the countdown to power shutdown begins.
(Shutdown power consumption is less than 1 A.)
- When a high signal level (3 to 35 Vdc) is detected on the SHTDWN cable, the timer is reset, and the recorder is powered on. Wake-up Feature The recorder includes a wake-up timer feature that can be used to communicate with the system server at regular intervals. Designed to work in conjunction with the shutdown timer, the wake-up feature lets system users know that the recorder is still functional, although it has been shut down. The wake-up time interval and duration are configurable. Automatic Over-the-air (OTA) software updates Configuration and firmware updates are completed over-the-
air (OTA).
