Host-to-IPI Communications
SIS commands consist of one or more characters per field. No special characters are required
to begin or end a command sequence. When the IPI determines that a command is valid, it
executes the command and sends a response to the host device. All responses from the IPI to
the host end with a carriage return and a line feed (CR/LF =
]
), which signals the end of the
response character string. A string is one or more characters.
IPI-initiated Messages
If you are communicating with the IPI via RS-232 or via a verbose Telnet connection when a local
event such as a front panel selection or adjustment takes place, the IPI responds by sending a
message to the host. No response is required from the host. The IPI-initiated messages are listed
here (underlined).

The IPI sends the boot and copyright messages under the following circumstances:
•
If the IPI is off and an RS-232 connection is already set up (the PC is cabled to the IPI 200
series unit and a serial terminal emulation program such as HyperTerminal is open), the
connected unit sends these messages via RS-232 when it is first powered on.
•
If the IPI is on, it sends the boot and copyright messages when you first open a Telnet
connection to the IPI. You can see the day of the week, date, and time if the IPI is connected
via Telnet, but not via RS-232. If you are using a Telnet connection, the copyright message,
date, and time are followed by a password prompt.
Additional messages may be sent by the IPI in response to front panel selections and volume
adjustments and when scripts are executed during scheduled events.
Password Information
The
]
Password: prompt requires a password (administrator level or user level) followed by a
carriage return. The prompt is repeated if the correct password is not entered.
If the correct password is entered, the unit responds with
]
Login Administrator
]
or
]
Login
User
]
, depending on the password entered. If passwords are the same for both
administrator and user, the unit will default to administrator privileges.
