Working with Terminal
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.
