BTMG-10 BACnet to Modbus protocol conversion module Application and function • BTMG-10 can map the current value of BACnet, the maximum of 100 AI / AO / AV and 100 BI / BO / BV. • BTMG-10 has two data ports, RJ-45 port to connect via BACnet IP protocol BACnet network, EIA-485 port via Modbus RTU protocol to connect from the device as a Modbus network, communication baud rate can be set to 4800/9600/19200 / 38400. • Users can use any editing software conbtm turn MODBUS BACnet variable mapping table, edited after the download to the gateway, the data can be achieved and MODUBS BACnet device data Free. • CMOS circuit, high reliability four-layer PCB board, and use the power / ground separation barrier. Powerful hardware and software of the controller and power supply filtering to ensure reliable and stable operation. CMOS microprocessor using an internal "watchdog" to monitor the supply voltage to provide automatic shutdown and data backup. BTMG-10 BACnet to Modbus protocol conversion module Technical parameters • Power 24 VAC @ 10VA. Half-wave rectifier, allowing the use of 24V with an AC power transformer to multiple controllers. AC 24V power supply which one foot grounded. • battery 3 .0 V battery to the clock power supply, power-down situations to work in 1.5 years. Charged case in the system, the battery life of 10 years. Battery model BR1225, users can replace themselves. • processor AVR CMOS processor (with FLASH, EEPROM, RAM) • BACIP support a BACIP bus, RJ-45 connection, communication speed of 76.8 Kbps. • Modbus communication support for EIA-485 (twisted-pair communication) 10 Modbus devices to connect. Communication configuration options ASC Ⅱ / RTU, 4800, or 9600 baud, odd / even / no parity, and stop bit options to suit all kinds of Modbus communications equipment. • size (112mm) H × (140mm) W × (38mm) D • Environment 0-55 ℃ .0-95% RH, non-condensing. • Software support for 100 BACnet AVs and 100 BVs, supports Modbus and BACnet map, you can read and write all of the AV or BV variable. • BACnet BACnet protocol conformance standards Comply with the standard EMC GB / T 17626
