ASMi-52 Ver. 2.5 Configuration Alternatives 3-7
• Remote management via out-of-band 10/100BaseT port or dedicated timeslot.
Remote management is performed using Telnet, or ConfiguRAD (RAD’s
Web-based application), or RADview (RAD’s SNMP-based management
system).
Managing ASMi-52 via a Terminal Port
This section describes how to prepare ASMi-52 and the supervisory terminal for a
control session.
Control Port Interface Characteristics
ASMi-52 includes a V.24 (RS-232) asynchronous DCE port, designated as
CONTROL and terminating 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 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.
ASMi-52 can also be managed via a hand-held control device, Easy Config. Refer to
Appendix C for detailed description of the device.
Preparing the Terminal
Any standard ASCII terminal (a “dumb” terminal or a personal computer running
a terminal emulation application) equipped with a V.24 (RS-232) communication
interface can be used to configure ASMi-52. Appendix A details the pin
assignments and control signal directions of the ASMi-52 control connector.
Data Terminal Ready (DTR)
When connected and turned on, the terminal sets the DTR line ON (active) to gain
control over ASMi-52 and starts a configuration or monitoring session.
Initiating a Control Session
To initiate a control session:
1. Connect the terminal cable to the CONTROL connector of ASMi-52.
2. Turn the control terminal on.
