The ESX-C2C is a compact CANbus module that combines extensive data logging functions with mobile communications to provide a complete solution for vehicle-based telemetry. Offering up to five I/Os, which can be specified in combinations of analogue inputs, digital inputs, frequency inputs, digital outputs and PWM outputs, the module bristles with communications capabilities to provide teleservice, gateway and data-logger functions to connect vehicle-mounted systems with the wider world.
At the heart of the ESX-C2C lies a powerful 16bit microcontroller, with 128Kbyte of static RAM, up to 2Mbyte of Flash memory and 4Kbyte of EEPROM. Its battery backed real-time clock will run for 15 years without power, and can be used to provide a wake-up call to the rest of the controller when in power saving mode.
The unit can be specified with one or two CANbus interfaces, one or two RS232 serial interfaces and there are even options for Bluetooth communications and GPS location services. But the key component in the ESX-C2C’s armoury is its dual-band GSM/GPRS module, providing a choice of telemetry facilities for vehicle systems.
Using this interface enables a huge range of applications, including remote control of vehicles-mounted systems, remote diagnostics using SMS text messages, data telemetry and even sophisticated security systems such as theft prevention and vehicle tracking (when used in conjunction with the GPS option).
The compact module comes in a rugged die-cast aluminium housing measuring 97 x 125 x 45mm and weighing in at around 500g. It is protected against electromagnetic interference, shock and vibration in accordance with international automotive, construction industry and agricultural standards. Sealing to an IP65 ingress rating is assured using a Gore-Tex breathing filter, which provides fanless operation over a wide -40 to +85C ambient temperature range while protecting the sensitive electronics from the environment typical in construction and agricultural applications.
The ESX-C2C runs from a similarly wide power input range from 9 to 32V DC, allowing its use in all standard vehicular electrical systems. Power consumption is low, with a typical operational current drain of 300mA, and a variety of power saving modes to reduce this to as little as 0.5mA.
With all these capabilities, the ESX-C2C is an ideal choice for monitoring and controlling a wide range of electrical and hydraulic systems mounted on all manner of vehicles, from the smallest delivery vehicle to the largest off-highway equipment.
