1. Introduction This manual is the reference book when setting up the DinBox RTU device. Because of the nature of this product and it's field of application, some degree of technical background knowledge regarding the application and data-communication is assumed. This RTU has the technical specifications to monitor 16 digital and 4 analogue inputs. It can send data to a CTU (central processing unit) or host via GSM data, GPRS or SMS messaging. The main functionality’s of the DinBox RTU are : • DIN rail mountable housing • Configuration, setup and monitoring via serial interface • 4 x analogue inputs • 16 x galvanically separated and independent digital inputs • 2 x galvanically separated and independent digital outputs • Wavecom Q24Plus GSM/GPRS or Q24Classic GSM module • Atmel AVR processor with RTC and FRAM • Power backup via SuperCaps or optional NiMH battery pack

2. Block Diagram The block diagram below details the location and interconnection of the different functional units within the RTU.

Power Supply The DinBox RTU is powered via a wide range ac mains power supply. The RTU is standard delivered with 10F SuperCap capacitor for –short time- power backup. If a -long time- backup is needed the RTU can optional be equiped with a battery charger and a NiMH battery pack. ps. backup periods depends on kind of application and firmware !

Configuration interface

All local communication with the RTU for configuration, setup and monitoring is done via the serial “config interface”.

GSM Module This RTU has a build-in Wavecom GSM/GPRS module. This module will be used to transfer data from/to the CTU or host system. The GSM module needs a SIM card with a disabled PIN code request. A dual band GSM antenna is mounted into the enclosure.

Atmel AVR processor All functionality’s are automatically guided by the Atmel processor. This processor will control the following tasks ; - enables/disables power supply regulators and DC/DC converters - communication with the real time clock - communication with the Wavecom GSM/GPRS module - communication with the AD converters to measure the AI’s - calculation on measured AI data - read data from DI - write data to DO - write and read data in non volatile memory

IO This RTU has 4 analogue inputs, 4 digital outputs and 16 digital inputs. 4 x AI - not galvanically separated - optional separation is possible on 2 channels 16 x DI - galvanically separated (opto coupler) - 8 dry inputs (needs 5 - 24Vdc to activate) - 8 dry inputs OR active inputs (short circuit to activate) (changeable via jumpers) 2 x DO - galvanically separated (opto mos relay)

FRAM The DinBox RTU has 4 FRAM (ferro electric RAM) of 64 Kb (8.192 x 8 bits). This non volatile memory will be used to store the configuration, measured data and log information. ps. the use of FRAM depends on the firmware used !

RTC The RTU has a built-in real time clock.

Disconnect the mains power before connecting or

disconnecting the power and/or DTE plugs ! 4. Ports and Connectors Before you start the installation, take a moment to become more familiar with the possible connections to and from the DinBox RTU.

4.1 Power Connection The DinBox RTU must be powered from mains. Power backup is provided via SuperCaps or via NiMH battery pack (optional). Always disconnect the mains power before connecting the power connection. 4.1.1 ac mains connection Connect the ac mains power supply to the ac mains connector. Make sure the voltage supplied to the DinBox RTU is in the range of the power supply specification (see specifications for details on voltage range). 4.1.2 SuperCap connection The DinBox RTU is standard delivered with a SuperCap backup. The SuperCap board with 4x Maxwell PC10 is directly soldered, via two wires, onto the DinBox PCB. 4.1.3 NiMH battery pack connection Connect the NiMH rechargeable battery pack (with 10K NTC resistor) to the battery connector. Only battery packs with a 10K NTC resistor can be used. Beware the correct polarity, black (-), red (+) and yellow (NTC) wire.

4.2 Configuration interface

Only devices which are conform with the safety regulations can be connected to the DTE port!

All local communication with the DinBox RTU for configuration, setup and the necessary maintenance tasks is done via the serial “configuration interface”. The RTU has a serial RS-232 interface (RJ-45) which can be connected to a computer or similar device via a RJ-45 to DB-9 serial cable. Only RxD (pin2, from RTU to PC), TxD (pin3, from PC to RTU) and DTR (pin 4, from PC to RTU) are used. If DTR is active the LED DTR will illuminate.

Output: from DCE (DinBox RTU) to DTE (terminal) Input: from DTE (terminal) to DCE (DinBox RTU)
