StudioStation 100 • Remote Communication and Control
73
Connection Timeouts
The Ethernet link times out after a designated period of time with no communication. By
default, this timeout value is 5 minutes, but the value can be changed.
NOTE:
Extron recommends leaving the default timeout at 5 minutes and periodically
issuing the Query (
Q
) command to keep the connection active. If there are long idle
periods, disconnect the socket and reopen the connection when another command
must be sent.
Verbose Mode
Telnet connections can be used to monitor for changes that occur, such as SIS commands
from other Telnet sockets or serial port changes. For a Telnet session to receive change
notices, the Telnet session must be in verbose mode 1 or 3. In verbose mode 1 or 3, the
Telnet socket reports changes in messages that resemble SIS command responses.
Host-to-device Communications
The StudioStation 100 accepts SIS commands through the rear panel Remote RS‑232 port,
the front panel Config port, and the rear panel Ethernet (LAN) port. SIS commands consist
of one or more characters per command field. They do not require special characters to
begin or end the command character sequence. Each response to an SIS command ends
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.
StudioStation 100 - initiated Messages
The StudioStation 100 initiates messages under specific conditions. No response is required
from the host. The StudioStation 100 initiated message is as follows:

The StudioStation 100 sends the copyright messages under the following circumstances:
•
If the StudioStation 100 is off and an RS‑232 connection is already set up (the PC
is cabled to the StudioStation 100 and a serial communication program such as
DataViewerl is open), the connected unit sends these messages via RS‑232 when first
powered on.
•
If the StudioStation 100 is on, it sends the copyright message when a Telnet connection
to the StudioStation 100 is first opened. The day of the week, date, and time are
shown when the StudioStation 100 is connected via Telnet, but not via RS‑232. If using
a Telnet connection, the copyright message, date, and time may be followed by a
password prompt.
Password Information
The

, depending on the password entered. If passwords are the same for
both administrator and user, the unit defaults to administrator privileges.
