Application Examples
7.1
ASCII Terminal to Host for Login
To connect a DTE (Data Terminal Equipment), a standard non-crossed cable
can be used for port 1.
Channel one is configured for speed, interface mode (typically 4C, N,8,1) and
flow control (hardware or XON/XOFF).
TCP port number is a user-selected arbitrary number (10000 is fine). Connect
Mode 01 (connect with any character--never accept network initiated
connections), remote IP Address set to the host, and the remote port number to
23 (telnet service).
Flush mode can be set to 80 to select the block-saving packing algorithm, and
no buffers are cleared.
A disconnect timeout can be set, whereas the DTR disconnect feature is
disabled (00)
7.2
RS-485 2-wire Prolongation Over Network
Two UTSes are used for this application: one at the "local" site and one at the
"remote" site. Only Channel 1 can be used because Channel 2 supports only
RS-232.
Assuming that one device initiates the dialog, the following shows a sample
setting.
Interface mode can be set based on RS-485 on 4-wire or 2-wire applications.
See Figure 4-2.
Flow control is usually not used in these applications (set to 00). The port
number can be any number; it is recommended to use the same value for both
units at the local and remote sites. (i.e. 10000)
Flush mode should be set to 80 to minimize packet count, unless both UTSes
are connected to a local LAN and minimal transmission delay is important.
Send Characters can be programmed to Block trailing Characters (like <CR>)
to speed up transmission.
Disconnect Mode should be set to 00.
