22. Serial Protocols
22.1. Introduction
This chapter familiarizes the user with:
• RawSocket Applications
• TCP Modbus Server Applications
• DNP (Distributed Network Protocol)
• Configuring Serial ports for RawSocket
• Viewing Serial Port and TCP Connection Status and Statistics
• Resetting Serial ports
• Tracing Serial Port activity
22.1.1. Serial IP Port Features
The RuggedCom Serial Server provides the following features for forwarding serial traffic over IP:
• Raw Socket Protocol - a means to transport streams of characters from one serial port on the router
to a specified remote IP address and TCP port
• RX1500 supports up to 24 serial ports; RX1501 supports up to 36 serial ports
• Bit rates of 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400 bps.
• Supports RS232, RS422 and RS485 party line operation.
• XON/XOFF flow control.
• Supports a point-to-point connection mode and a broadcast connection mode in which up to 32 remote
servers may connect to a central server.
• TCP/IP incoming, outgoing or both incoming/outgoing connections mode, configurable local and
remote TCP port numbers.
• Packetize and send data on a full packet, a specific character or upon a timeout.
• Supports a “turnaround” time to enforce minimum times between messages sent out the serial port.
• Debugging facilities including connection tracing and statistics
22.1.1.1. LED Designations
Each RJ45 connector on the 6S01 serial module features a single LED. The LED illuminates to indicate
serial traffic.
