by The Leading Enterprise Internet of Things Solution ALTA Serial Modbus Gateway General Description ALTA Serial Modbus Gateway Features The ALTA Serial Modbus Gateway (SMG) acts as a Wireless range of 1,200+ feet through 12-14 walls * data concentrator for Monnits ALTA long range wireless 900 MHz Frequency Hopping Spread Spectrum sensor networks. This device allows you to connect up (FHSS), 868 and 433 MHz Frequency Agile to 50 wireless sensing devices, per gateway, to your Improved interference immunity existing serial Modbus RS-232C and RS-485 sensing Encrypt-RF Security (Diffie-Hellman Key Exchange + and control infrastructures. AES-128 CBC for sensor data messages) 16,000 sensor message memory Monnit has recognized the importance of using open Over the air updates (future proof) standards like Modbus, allowing ALTA wireless sensors Communicates with Modbus RTU / ASCII Serial to be used in the majority of industrial applications. Protocols Modbus is often used to connect a supervisory computer Supports RS-232C / RS-485 Interfacing with a remote terminal unit (RTU) in supervisory control LED Status Indicators and data acquisition (SCADA) systems. Modbus allows NEMA 4X / IP65 Rated Enclosure for communication between many (approximately 247) RP SMA Antenna Connector (Antenna Included) devices connected to the same wired network. Therefore, ALTA SMGs allows for seemingly unlimited wireless * Actual range may vary depending on environment. expansion to a traditional wired network. A system incorporating an ALTA SMG would consists of Wireless Range Comparison the following: Wireless Range Comparison Modbus Master PLC, SCADA, etc. Existing RS-232C or RS-485 Infrastructure Monnit ALTA ALTA Serial Modbus Gateway (SMG) ALTA Wireless Sensors Monnit Applications Process automation protocols Other Wireless Platforms Industrial control system protocols Building automation protocols Power system automation protocols Automatic meter reading protocols Wifi Automobile / Vehicle protocol buses In any existing Modbus system Bluetooth PAGE 14.528 in (139.700 mm) L System L Wired L Wireless Serial Modbus Gateway for Long Range Wireless Sensors 4.528 in 7.07 in (139.700 mm) (179.603 mm) L System L Wired Wireless Serial Modbus Gateway L for Long Range Wireless Sensors 7.07 in (179.603 mm) ALTA Serial Modbus Gateway Specifications Wireless Wireless Range 1,200+ ft. non-line-of-sight * Security Encrypt-RF (256-bit key exchange and AES-128 CTR) Monnit Radio Support ALTA Wireless Module by Monnit Frequencies: 900, 868 and 433 MHz Antenna Connector: RP-SMA Gain: 5.0 dBi Standard Industry Certifications 900 MHz product FCC ID: ZTL- G2SC1 and IC: 9794A-G2SC1. 868 and Canada 433 MHz product tested and found to comply with: EN 300 220-2 V3.1.1 (2017-02), EN 300 220-2 V3.1.1 (2017-02) and EN 60950. 3 Wire Communication Interface RS-232C TXD (OUT), RXD (IN), and Ground / Common RS-485 D+, D-, and Ground / Common Protocol Selector Jumper for RS-232 and RS485 Power Input Voltage Range 4.5 - 36.0 VDC ** Minimum Current Required 100mA (500mA Recommended) Environmental Operating Temperature -40C to +85C (-40F to 185F) *** Storage Temperature -40C to +85C (-40F to 185F) Mechanical LEDs Wireless Activity, Wired Activity, System Status Reset Feature Communication / Factory Settings Reset Jumper Enclosure Durable, Impact-Resistant UV Stabilized Polycarbonate (IP65 of IEC 529 and NEMA 1, 2, 4, 4x, 12 and 13 Rated) Dimensions 179.603 x 90.678 x 41.30 mm Weight 16 ounces * Actual range may vary depending on environment. ** Hardware cannot withstand negative voltage.
