Robustel’s R1511 router is a Dual Ethernet port (LAN + WAN) 2G/3G/4G/LTE router with advanced software functions and a dedicated serial port at a very competitive price point.
The R1511 is a sister product of the R1510 series offering a choice of (3-wire) RS232 or (2-wire) RS485 instead of the Digital Input and Digital Output found on R1510 series.
This means that RS232 and RS485 devices, including Modbus RTU equipment can connect to the internet directly through the R1511 router. The Ethernet port can be independently configured as WAN, LAN1 or LAN2 and Ethernet port 1 as LAN1 or LAN2.
