Introduction

In modern Building Management Systems (BMS) and Industrial Automation environments, a critical challenge arises from the diverse array of communication protocols used by equipment from different manufacturers. Achieving seamless interoperability between these heterogeneous systems is essential for creating unified, efficient, and intelligent operations. Without a common language, valuable data remains siloed, and integrated control becomes complex and costly to implement.

The San Telequip GW BMS 02 02 Automation Protocol Converter is an external, multi-protocol device server engineered to solve this fundamental integration problem. Its primary function is to provide robust and reliable protocol translation between Serial-Serial, Serial-Ethernet, and Ethernet-Ethernet devices. By natively supporting a wide range of industry-standard protocols—including LonWorks®, BACnet, MetasysN2, and Modbus—the converter acts as a powerful universal translator. It includes all the necessary hardware and software drivers to enable a customer's products to interface with various field networks, delivering powerful interoperability through a dedicated and feature-rich design.

Standards
RS485 Protocols: Modbus RTU, Allen Bradley DF1, BACnet MS/TP, MetasysN2, LON Ethernet Protocols: Allen Bradley Ethernet/IP, BACnet IP, BACnet Ethernet, Modbus TCP/IP, SNMP, XML, DNP3 Ethernet
BACnet Data Types: AI, AV, AO, BI, BV, BO, MI, MV, MO, LSP, Device
Performance
Point Count: Max 1200 points
Point Upgrades: Point count can be upgraded to 5000/10000 on some models and to 4096 on Device Capacity: Up to 32 devices can be multi-dropped on the Modbus RTU/BACnet MSTP/N2 side. This number is dependent on site conditions. An RS485 repeater may be required to meet network criteria and achieve maximum device count.
Interface
Serial Port: 1x RS485 (2-Wire / 4-wire, 5-pin connector)
Ethernet Port: 1x 10/100 Ethernet Port (RJ45 Connector).
Configuration: Via web browser
Indicators
LEDs for Tx, Rx, and Power status.
Cable Distance
RS485 Repeater may be necessary to meet basic RS485 network criteria, implying standard distance limitations apply.
Electrical Characteristics
