SX15-PRO the latest evolution for the RCM3700 control board Publication Date: 10-03-2008 | Versione Italiana  | English Version Tags: - Rabbit - Rabbit Serie 3000 - Schede Area SX -

SX15-PRO is the last evolution of the SX15 board. It is equipped with all the features of the former versions, moreover now SX15-PRO adds new functions very interesting for the developing of several applications: among the main new characteristic consider the radiofrequency module on 2.4GHz with ZigBee technology, providing also two AD channels with 10bit resolution.

Introduction

Rabbit modules from RCM3600 and RCM3700 series, even if on the market for some time, still have the leadership for the best ratio cost / performances of the entire product range; for this reason the third evolution of the SX15 board has born. Still keeping unchanged the general structure that encountered good success, then it adds more flexibility and peripherals very useful for the developing of large of number of projects.

Among the most interesting new features, we want top ut in evidence the introduction of an host connector for Xbee module (The Xbee and Xbee Pro modules: the wireless Zigbee transmissions made easy); This module allows realizing, in an extreme easy way, a very reliable wireless network in Zigbee 2.4GHz technology, with a coverage range up to 1500 meters in ideal conditions (version Pro of the module and antennas in straight view).

Beside this main feature, the module provides also other side functions, but very useful. For example, it is possible to use 2 A/D conversion channels with 10 bit resolution, both readable directly through AT command, the same for module control.

Another new is the elimination of the adapting small board between the Telit GM862 (GSM/GPRS/GPS) module and the SX15-Pro board itself. This allows to fully use many of the interesting features of this module, for example receiving the NMEA sentences from the GPS receiver directly on second serial port of the modem, so without interacting with the normal AT communication.

The hardware equipment is completed by a robust power supply section, where the response to noises and transients on the power line has been improved to obtain an higher reliability.

General features

The main features of the SX15-Pro board are summarized in the following lines:

• Extended voltage range power supply (9-15V AC/DC)
• Power line noise cancelling device
• Backup lithium battery for RCM module
• Host connector suitable for RCM3600/RCM3610/RCM3700/RCM3710/RCM3750 processors
• Host connector for Telit GSM/GPRS/GPS module (GSM/GPRS Quad Band Modem Engine with S1 adapter board)
• Host connector for reader module of SD/MMC cards with PC compliant filesystem (SD and MMC card reader with serial TTL interface)
• Host connector for humidity and temperature sensor SH75 (Sensori di umidità e temperatura monolitici con uscita digitale)
• Host connector for Xbee module, in both versions normal and PRO (The Xbee and Xbee Pro modules: the wireless Zigbee transmissions made easy)
• Host connector for radofrequency transceiver module ER400TRS (Trasmissioni in Radiofrequenza facili con Easy Radio)
• Host connector for serial microcamera CAM-VGA100 (Una compatta video camera seriale in soli 3.2 x 3.2 cm) to be uese as a CMOS serial port
• RS232 DTE serial port
• RS485 serial port
• 2 AD channels (0V-3.3V) with 10 bit resolution (on board of the optional XBee module)
• 1 expander connector for FLEX boards (FLEX-Analog: an analog acquisition board with flexibility in mind! and Flex-Output board: a 6 rele expander forr all the Area SX master boards) and SX16 (SX16B - IN/OUT expansion board)
• 1 expander connector for SXLCD display board (SXLCD: how to drive an LCD display with a serial line) and dimmer SX13 (Multifunctions dimmer)
• 3 expander connectors for general purpose
• 1 expander connector for analog audio signal of the modem
• 5 signalling LEDs
• 1 button

  Board configuration

  The wide availability of board peripherals makes the hardware not completely usable at the same time. For this reason on the board you fine 16 configuration switches that allow assigning the microprocessor serial ports only to the needed peripherals. A clear and simple serigraphy allows setting the chosen configuration without and need of further documentation.
  
  In the following the allowed configuration are described:
  

  
  

  Serial Port	Peripherals
  SER D	Serial DTE
  	MMC Card
  	VGA CAM
  SER B	FLEX Bus
  	MMC Card
  	GPS
  SER E	XBee Module
  	GPS

  Compliance with the former version and hardware extensions

  The new SX15-PRO board is fully compliant with the former version SX15-EVO.
  The only differences deal with the GSP module REB700, that is not available anymore in this version since the GPS receiver is directly integrated in the Telit GM862-GPS modem, and the input for the backup battery that has been removed.
  But all the firmware codes developed for the SX15-EVO board, included the source codes you fine in the article SX15-Evo - Even more power and flexibility!, still remain properly working and may be used as projects start-up.

  Expander connectors of the SX15-PRO allow the same hardware connections of the former version. So it is possible to control chains of the following optional boards: SX16B input/out boards (SX16B - IN/OUT expansion board), FLEX Output boards (Flex-Output board: a 6 rele expander forr all the Area SX master boards), FLEX Analog boards (FLEX-Analog: an analog acquisition board with flexibility in mind!), dimmer SX13 (Load and power control with the new version of SX13 Dimmer), LCD display with SXLCD interface (SXLCD: how to drive an LCD display with a serial line). This way it is also possible to realize remote control systems with the chosen number of input and output both analog and digital, but also other interfaces able to fit a lot of needs.

  The compliance with the former version concerns also with mechanical matters: so the board has the same dimensions and the same fastening bores position. This way it still can fit the same anodized aluminium case to realize end user devices.
