Preparing for a Control Session 4-1

Chapter 4

Managing ASMi-52 via a

Terminal

The configuration of ASMi-52 is performed via menu-driven embedded software,

using a standard ASCII terminal or a PC running a terminal emulation application

connected to the rear panel CONTROL port. Alternatively, ASMi-52 can be

managed from a Telnet host connected to the 10/100BASE-T port on the rear

panel.

4.1 Preparing for a Control Session

This section describes how to prepare ASMi-52 and the supervisory terminal for a

control session.

Managing ASMi-52 via Terminal Port

Control Port Interface Characteristics

ASMi-52 includes a V.24 (RS-232) asynchronous DCE port, designated CONTROL

and terminated in a 9-pin D-type female connector. The control port continuously

monitors the incoming data stream and immediately responds to any input string

received through this port.

The terminal can be connected either directly to the ASMi-52 control port, or

through a modem or any other type of full-duplex data link. The ASMi-52 control

port interface type must be set in accordance with the connection method, as

follows:

• DCE – direct connection to terminals. Since terminals usually have DTE

interfaces, the connection to the port is made by means of a straight-through

cable.

• DTE – connection through a modem or data link. In this case, you need a cross

cable (also called a null modem cable) to connect to the CONTROL connector.

The ASMi-52 control port can be configured to communicate at the following rates:

9.6, 19.2, 38.4, 57.6 or 115.2 kbps.

The word format consists of one stop bit, 8 data bits, and no parity.
