5.5. COM Port Configuration
Users can configure Serial parameters including UART mode, baud rate, parity, data bit and type of flow
control and the mode of operations, which are TCP Server, TCP Client, and UDP modes. The COM Port
Configuration page is shown in Fig. 26.
5.5.1. TCP Server Mode
TCP Server mode is the default Link mode of Serial Settings as shown in Fig. 27. In this mode, the
connection waits for a connecting requirement from a remote host PC which is running a “Serial to IP” utility
or setting EW5302 in tunneling mode. Users need to configure a listening port to allow clients establishing a
connection to this server. Default port number of COM1 is 4660.
IP filtering function is a simple ACL (Access Control List) for incoming IP packets. It can be disabled by
setting Source IP to “0.0.0.0”. Users can configure one or a group of IP address for Source IP. If IP filter is
enabled, only source IP assigned can be connected to EW5302.
Note: Enable Virtual COM mode if the remote site PC’s “Serial to IP” tool is installed
5.5.2. TCP Client Mode
Users may enter a Destination IP and Destination port (default: 4660) to establish a connection of
counter-pair (remote) host (for example, another EW5302 or PC for data collection) as shown in Fig. 28.
EW5302 can support up to two destination hosts simultaneously.
