ISAAC InMetrics – WRU201

Recorder and Wireless Router

WRU201-EN-Rev3

1 / 7

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 vehicle’s 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.

ISAAC InMetrics – WRU201 Recorder and Wireless Router Operation Details Circuit Protection Digital Inputs The recorder features built-in fuses that provide circuit protection to the entire system and peripherals. 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.
