determined using the ping (ICMP) utility (see
for more details). If the addresses have not been changed, the factory-specified defaults
are: IP address: 192.168.254.254, subnet mask: 255.255.0.0, gateway address: 0.0.0.0
Establishing a Connection
Establish a network connection to the processor as follows:
1.
Open a TCP socket to port 23 using the processor IP address.
NOTE: If the local system administrators have not changed the value, the factory-
specified default, 192.168.254.254, is the correct value for this field.
The processor responds with a copyright message including the date, the name of
the product, firmware version, part number, and the current date/time.
NOTES:
•
•
2.
If the processor is password protected, enter the appropriate administrator or user
password.
•
If the password is accepted, the processor responds with Login User or
Login Administrator.
•
If the password is not accepted, the Password prompt reappears.
NOTE: The factory configured passwords for all accounts on this device have
been set to the device serial number. In the event of a complete system reset,
the passwords convert to the default, which is no password (see
page 70 to change the password using PCS or
change the passwords using the internal web page).
Connection Timeouts
The Ethernet link times out after a designated period of time of no communications. By
default, this timeout value is set to five minutes but the value can be changed.
NOTE: Extron recommends leaving the default timeout at five minutes and periodically
issuing the Query (Q) command to keep the connection active. If there are long
idle periods, Extron recommends disconnecting the socket and reopening the
connection when another command must be sent.
Number of Connections
The Annotator 300 can have up to 200 simultaneous TCP connections, including all HTTP
sockets and Telnet connections. When the connection limit is reached, the processor
accepts no new connections until some have been closed. No error message or indication
is given that the connection limit has been reached. To maximize performance of an IP
Link device, the number of connections should stay low and unnecessary open sockets
should be closed.
If the processor is not password-protected, the device is ready to accept SIS
commands immediately after it sends the copyright message.
If the processor is password-protected, a password prompt appears below
the copyright message.
