ADVANTECH BB-MESR921-MT

Modbus Ethernet/Serial Gateway – DB9/TB, Multi-mode ST, UL C1/D2

The BB-MESR921-MT Modbus Gateway bridges devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP networks, allowing seamless integration. Serial ports can be accessed over a LAN or WAN using Direct IP Mode connections. Supporting up to 16 masters and 32 slaves, the gateway features auto-detecting 10/100 copper and fiber optic. Easy-to-use software is designed for Windows 2000, 2003 Server, XP, Vista, 2008 Server, 7, 8, 10. Serial data rates up to 230 kbps ensure maximum network flexibility.
