26. to send the programming of the LIN103 via the network The LIN103 can exchange data with remote stations using the TCP IP or UDP IP protocol according to the configuration of the Transport Protocol parameters and can operate both as master and slave Other settings refer to the IP address the address of the destination Data Port the IP address of the gateway the NetMask and the connection time out In addition to the TCP and UDP protocols the LIN103 also supports ARP and ICMP ping This makes it possible to send a ping to any other appliance of the network in order to check effective connection A 2 RS232 Port The serial port of the LIN103 supports TX RX CTS and RTS signals and can work at baudrates up to 115200 In Transparent Mode MODE 1 the serial port transmits the data between the LIN103 and attached serial device microcontroller In the Serial Programming Mode the port is used to program the LIN103 s Settings Settings that define the operation of the serial port include the Baudrate 150 115200bps Parity none even or odd Bits Per Byte 7 or 8 and Flow Control none or CTS RTS Each of these Settings has a matching Parameter that overrides the value of a corresponding Setting A 3 Routing Buffers The data between the Ethernet port and the serial port is routed via two independent 255 byte buffers one for each routing direction Buffers are necessary because the Ethernet and the serial port operate at different sp
