1. Scope The present document describes the Acuity Edger Router ER-550 hardware features. 2. Introduction • • • • • • • • • The Acuity Edge Router ER-550 is designed to fulfill communications and data acquisition requirement and use multiple communication channels (GPRS/EDGE WAN + 10/100Base-T Ethernet port) and gather data via the 2.4GHz mesh network radio link. The board is configured as intelligent LAN to WAN gateway for mesh sensor networks applications.

The Edge Router includes an ARM9 processor as the main processing entity that controls most of the system features (some features are integrated internally into chip). Subsystems controlled by the ARM processor are: • Two directly connected serial channels. First channel is used for serial console port used for factory programming and as debug console and is available on the as RS232 connection.
present in order to efficiently provide the voltages for OEM modules and control the power. Power supply can be switched ON/OFF under ARM control (separate for each OEM module installed), the ARM power and USB hub power can be switched ON/OFF under MSP430 control in order to support fine power management and a large combination of modes of operation.
5. User Configuration & Connections 5.1 Power Connection • • • Power is connected trough grummet situated on the right side of the unit Recommended connection via PVC or Teflon insulated power cable with minimal AWG #24 conductor size. Please check installation manual for other available connection types GPRS Antenna Ethernet AC Power Input Proprietary & Confidential – NIVIS LLC Page 7 - V1.0 2.
5.2 External Ethernet Port Connection (10/100Base-T, RJ45) • • • Ethernet port connects externally trough an RJ-45 type water proof connection on top of the enclosure Proper cabling need to be used according to specifications for network cabling.
5.4 Antenna Ports • • Antenna ports are situated on the sides of the enclosure. Antennas used have been specified in accordance to FCC certifications for the device. 2.4GHz Mesh LAN Antenna • GPRS/EDGE Antenna On the left side of enclosure (the pedal shaped antenna) is the WAN connection antenna. This is a quad band antenna specifically designed for GSM/GPRS operation. GPRS/EDGE – WAN ANTENNA Description ANTENNA RUBBR DUCK MULT-BAND SMA Model T6140AM-AGDPU-S Manufacturer Nearson Inc.
