Antaira STM-501C 1-Port Modbus TCP to Serial RTU/ASCII Gateway

The STM-501C, MODBUS gateway allows legacy MODBUS RTU/ASCII devices to operate on a MODBUS TCP network. MODBUS serial master or slave may communicate with MODBUS TCP's slave or master. For Modbus TCP master to Modbus RTU/ASCII slave mode, the STM-501C allows multiple MODBUS TCP masters to communicate with a MODBUS serial network. Since a MODBUS serial network can only handle one query at one time, queries from different masters are pipelined and processed one by one. For Modbus RTU/ASCII master to Modbus TCP slave mode, the STM-501C functions as the MODBUS RTU/ASCII master to MODBUS TCP slave gateway. The STM-501C can connect up to 8 MODBUS TCP slaves. Users can specify a UID range for each MODBUS TCP slave.

An inactive timeout that allows users to specify a time period to disconnect TCP/IP connection if there is no activity in the network. If the connection does not disconnect, it would occupy one connection slot and prevent any another connection again. User friendly software management tools offer an easy way to configure the STM-501C. The software utilities search all serial device servers within a local area network independent of its subnet. It will find a serial device server of a specific IP address over a wide area network. The STM-501C may be configured by its console port, through telnet connection, or by a web browser.
