ZyWAN User Manual Configuring the ZyWAN

The Table of Terminal Servers looks like this:

The following fields and options are available and must be set for each configured

Terminal Server configuration:

Field/Option Explanation

IP Port

Enter the IP port number (between 1 and 65535) to be used on

the ZyWAN for incoming TCP/IP connections from a network

client application. The IP address to which the client connects

may be any valid address configured for the ZyWAN on any

interface.

Time to Live

Enter the Time To Live for the connection (in seconds). This is

the maximum time of no activity from the network-connected

client, before the ZyWAN closes the Terminal Server connection.

Duplex

Select the duplex mode for the Terminal Server. This selects a

mode of operation for handling bi-directional communication with

a serial device.

Half Duplex: This mode is designed for simple request-response

networks, especially where serial port sharing with another

Terminal Server may be required. After a request is received

from the network and sent to the serial port, one response is

expected. After the serial port times out or after one response is

received and returned to the network client, the Terminal Server

does not read any more serial data until the next request.
