To establish a network connection to the DMP 64:

Open a TCP socket to port 23 using the mixer 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 DMP 64 responds with a copyright message including the date, the name of the
product, firmware version, part number, and the current date and time.

If the DMP 64 is not password-protected, the device is ready to accept SIS
commands immediately after it sends the copyright message.

If the DMP 64 is password-protected, a

password

prompt appears below the

If the device is password protected, enter the appropriate administrator or user
password.

If the password is accepted, the device responds with

Administrator

If the password is not accepted, the

Password

prompt reappears. Repeat step 3.

Connection Timeouts

The Ethernet link times out after a designated period of time of no communications. By
default, this timeout value is set to 5 minutes but the value can be changed. See the
Configure Port Timeout commands in the

“Command and Response Table for

Basic SIS Commands”

beginning on page 98.

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 a serial port. 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.
